Verisart: Using Blockchain to Verify the Authenticity of Art

Published

on

British contemporary artist Philip Colbert has long been considering creating his own catalog system to prove the authenticity of his expanding collection: enter Rob Norton, the founder of Verisart, a U.S.-based startup that’s using blockchain to verify the authenticity of artwork.

As we know, blockchain creates an immutable record of every transaction — whether it be art, labor and land, or cryptocurrencies. Widespread adoption of the technology could give a boost to the market for art online, which has yet to explode. Online sales currently account for only about 8%, or $5.4 billion, of the global art market, according to a report by UBS Group AG and Art Basel released this month.

“Art is a currency in a way; at the end of the day when they come to auction, the provenance is a very important element of their value.”

Trust, or lack of it, is at the core of the challenge, with potential buyers balking at the possibility of spending considerable sums on works whose authenticity can’t be fully verified. In fact, according to Norton, the value of fake art sold is almost double the real thing.

When it comes to art, “there’s a higher hurdle of trust that you have to clear, you have to know that what you’re buying is real,” said Norton. “Art is the second-largest unregulated market after illicit drugs and it’s significantly overshadowed by fraudulent activity. You can accelerate trust and liquidity by providing better standards for verifiable, global certification.”

Verisart

Verisart started in 2015 as a phone app that permitted artists to create their own systems of art verification. When that approach didn’t take off as expected, the company built a web app working with Ahmed Elgammal, a computer science professor at Rutgers University.

“We were a little bit early, we were figuring out where the market was, getting feedback from artists, and building a platform that people could use,” Norton said. “Now increasingly working with partners, those certificates can be customized.”

Colbert’s certificates, for example, contain small reproductions of the piece itself called “image hashes,” along with all of the relevant information about its creation, ownership, and movement — such as whether it was part of an exhibition.

“The blockchain is a more efficient method of verification,” Colbert said. “You’re not worried about the authentic value of your work, because it’s all about locking down the time and place. Then all those fakes aren’t doing you any damage. All those fake Mona Lisas don’t do the Mona Lisa any harm.”

Ultimately, putting art on the blockchain could lead to a decentralized art registry that would cover a significant amount of the world’s art. Although blockchain certification on its own may increasingly turn into a generic service, potentially being explored by big players such as Alphabet, Facebook, and Microsoft, Norton hopes Verisart’s ability to allow artists to customize their own certificates and image hashes will give it a competitive edge.

DAstra Network’s Launchpad and Token Constructor: Simple and Decentralized

Published

on

Currently, the world of cryptocurrencies and Decentralized Finance (DeFi) is developing rapidly, offering new opportunities and solutions for various areas of life. Attracting investments was no exception: unlike traditional investment platforms, where all decisions are made by a centralized team, crypto panels are based on blockchain technology, which allows network participants to independently make decisions and control their investments. The trend towards decentralization and increased user control over their data is called WEB3. To promote WEB3, you need simple and affordable solutions – this is what DAstra Network is ready to Tokenization and WEB3 provide.

Tokenization and WEB3

Launchpads, ICOs and IDOs are effective and proven ways to raise investments within the WEB3 paradigm. In exchange for investment, investors receive native tokens of the project, which they can use at their discretion.

Tokenization allows for fractional ownership and liquidity of traditionally illiquid assets, such as real estate or early-stage startups. Tokens can represent shares in a company, access to certain products or services, or have other features and benefits. If this is a GameFi Play2Earn project, then the tokens can represent in-game currency or in-game assets. Ultimately, tokens can be liquid and traded on cryptocurrency exchanges, allowing investors to quickly sell them or exchange them for other assets.

However, despite all the advantages of WEB3, the entry threshhold for using decentralized services remains quite high. For example, most people interested in cryptocurrency still prefer to use centralized crypto exchanges (CEX) such as Binance and Coinbase, but face difficulties when trying to use decentralized exchanges (DEX).

What is DAstra Network?

DAstra Network is a decentralized, but simple to use investment platform that empowers startups and businesses to obtain financial support for their solutions. By harnessing the power of tokenization , the platform facilitates startups in creating and listing tokens to attract funding opportunities. With just a few clicks, startups can now create tokens and list them on the platform to secure funding. This grants them the opportunity to tap into funds from private investors, venture capital firms, and passionate supporters worldwide.

DAstra Network ecosystem consists from 3 modules:

  1. The Launchpad platform offers a secure way to attract investments and protect investor capital by utilizing smart contracts.
  2. The platform uses a native DAN token that can be used to pay for services related to the issuance of digital rights. Additionally, token holders can enjoy additional benefits
  3. Our platform provides an internal exchange where investors can trade and sell digital financial assets of various projects. This exchange facilitates the seamless transfer of assets between investors.

Key strategic decisions on the development of the DAstra Network are made by the Decentralized Autonomous Organization. DAO participants not only take part in the management of Dastra, but also have the opportunity to earn up to 2 percent of the investments they attract to the project. The level of privileges in the DAO is determined by the number of DAN tokens held and involvement in the development of the DAstra Network

Native token

The DAstra Network uses native ERC-20 token called DAN. This token provides holders with various privileges:

  • Priority queue for investments in the most promising projects
  • Opportunity to participate in the wide selection of business projects for admission to the platform
  • Discounts on services for promoting investment projects.
  • Reduced fees for companies from attracted investments

The price of the token at the presale is only $0.008, and at the listing stage it is $0.021. This means that investors will be able to receive almost 300% profit!

Conclusion

Our future plans include expanding the DAstra Network platform to become an internationally recognized investment accelerator management system. This platform will feature its own decentralized fund, enabling startups selected by DAO members to receive funding. Our plan is to promote web3 and decentralization, bring more liquidity to the crypto market and venture capital, while keeping things simple and easy.

Polkadot reveals future-proof scaling updates at sub0 developer conference

Published

on

Developers of Polkadot, the blockspace ecosystem for boundless innovation, will start testing a new process that will provide radical scaling solutions for the network within a matter of weeks.

The plans were unveiled at sub0, the Polkadot Developer Conference, by Sophia Gold, Engineering Lead at Parity Technologies, a leading contributor to Polkadot.

She said asynchronous backing would enable Polkadot to more than triple its number of validators by the end of 2024 to around 1,000, describing this as “the most significant evolution of parachain consensus since we launched parachains almost two years ago.”

She added: “What’s unique about backing in Polkadot is that it’s enshrined – it’s implemented natively on the protocol level and not on the smart contract level, which gives us capital efficiency and censorship resistance. Asynchronous backing enables flexible scheduling for our future scaling work through elastic scaling and instantaneous coretime. We have a credible roadmap to get Polkadot to support 1,000 parachains and 1m+ transactions per second. The design is there – we know how to scale Polkadot for the indefinite future.”

A release of asynchronous backing is due to be deployed to Polkadot’s Rococo testnet in about two weeks.

Habermeier expands blockspace narrative

Sophia Gold was followed on-stage by Polkadot cofounder Robert Habermeier, who unveiled new concepts and architectural components that would enable roadmap features first outlined at Polkadot Decoded in June.

These features, including those known as ‘agile coretime’ and ‘elastic scaling’, would enable more flexible and efficient use of Polkadot’s blockspace and computing power, better serving innovators at all stages of growth, and taking the network beyond the existing parachain model.

He outlined a proposal for a new process of submitting work to Polkadot that would enable the network to process a much wider range of activity than parachains alone, including the ability to deploy smart contracts directly to a Polkadot core.

He explained: “This is how you would get to the point of cores being used by different parachains or bundled in all these different ways without having to enshrine that directly into Polkadot’s protocol. Rather, we make it possible through experimentation at higher levels.”

This new model would also enable a much anticipated feature known as atomic composability, enabling simultaneous execution of operations from multiple parachains at a time for more complex cross-chain transactions.

Accelerating smart contract delivery

The second day provided some important updates on the work carried out by OpenZeppelin on the OpenBrush contract library, intended to ease the development of Polkadot’s native ink! smart contracts. This includes the creation of easily implementable and extensible smart contract standards and translating Solidity contracts into ink!.

Felix Wegener, Security Services Manager of OpenZeppelin, said: “We made suggestions on how to change design choices, tooling, upgradeability and macros, and moving forward we see great promise in the ongoing developments of the Polkadot ecosystem.”

João Santos, Project Manager of OpenZeppelin, said his team had proposed open-source parachain runtimes and underlying FRAME pallets to accelerate the development and deployment of new and secure parachains.

He added: “We believe the initial step here is a generic runtime to allow projects to have a common base and start building immediately. Then we can start taking the learning we had developing this runtime, take the community feedback and then think about what’s next.”

New Ledger app coming

Juan Leni, CEO of Zondax, a major software developer for the Ledger hardware wallet, explained how his team is developing a new Ledger app for Polkadot that depends on verifiable metadata. He said: “I haven’t seen anything similar in other ecosystems. It will feature very minimal updates to the runtimes and to the wallets, we started research and development back in June.”

The single Ledger app can support any parachain in the Polkadot ecosystem, a boost for user experience of cold wallets on Polkadot, as previously, a separate app was required for each network. The app will feature clear signing of all transactions for maximum security.

His colleague Fernando Theirs said: “The integration for new parachains should be super simple. If you respect the metadata protocol it should be almost out of the box.”

Attendees also heard how Snowbridge, an Ethereum bridge to be built on the Polkadot Bridge Hub, is in position to deploy on the protocol’s canary network before the end of the year.

The plan is for each parachain to have its own dedicated messaging channel to Ethereum, unlocking a high degree of flexibility. Snowbridge is a trustless, decentralized mechanism for linking the Ethereum and Polkadot ecosystems, and is designed for general purpose.

About Polkadot

Polkadot is the blockspace ecosystem for boundless innovation. It enables Web3’s biggest innovators to get their ideas to market fast, with flexible costs and token options. By making blockchain technology secure, composable, flexible, efficient, and cost-effective, Polkadot is powering the movement for a better web.

Solar Dex to relaunch on Quai Network

Published

on

While many solutions for blockchain scalability have been proposed, they remain unable to crack the blockchain trilemma, sacrificing security and decentralization. Quai is the first blockchain protocol that is simultaneously decentralized, censorship resistant and infinitely scalable. Quai, in contrast to traditional cryptocurrencies, functions as a network of many interoperable blockchains braided together. Due to a breakthrough discovery that occurred during research on proof-of-work, Quai Network utilizes a new consensus mechanism, proof of entropy minima (PoEM), which eliminates all consensus-based forks and enables all Quai nodes to remain in “perpetual consensus.”

Solar Dex began as the first United States-based decentralized exchange on Solana, and will now be pivoting to build on Quai as one of its first DEXs. Due to a loss of TVL on Solana and many Solana-based projects moving strictly to NFTs, the Solar team has decided to get ahead of the DeFi curve and take advantage of Quai’s low-cost, high-speed decentralized network in order to better position Solar Dex for the next bull run. The team at Solar is building on top of Quai Network to “ensure a more sustainable future for Solar Dex.”

Roy Fardin, chief business officer, said: “After talking to the Quai Network team, we have never been more bullish about a layer 1 with scalability and its passion for growth. It was a clear eye-opener that they care about DeFi and want other projects that utilize this network to succeed. The vision behind Quai brings the best of Ethereum and Solana all together into this new network.”

Solar Dex will be reworking the DEX into several components as it builds on Quai. The DEX will not only support traditional swaps, but also add in customizable swap themes. In addition, Solar Dex’s Solar Sentries NFTs will allow staking as a yield opportunity derived by all exchange fees earned from Sentry Mode projects.

Richard, CEO of Solar Dex, said: “On top of traditional DEX swaps, Solar Dex will be adding limit orders on Quai. “We’re doing a total revamp of the website and DEX which should be very aesthetically pleasing and simplistic to onboard new users to DeFi and also Quai.”

With Quai’s Iron Age Testnet beginning in September 2023, Solar Dex will be prioritizing its deployment on Quai for the coming months. There will be incentives to beta-test Solar DEX on Quai and additional generalized rewards will be provided by Quai for participating in the Iron Age Testnet. On top of this, the Solar team will be adding a surprise feature to the DEX to build excitement for Quai’s testnet launch, as well as utilizing its incentive program to reward holders.

With backing from Polychain Capital and an expert team with backgrounds at Apple, GridPlus, Tesla, Consensys, Circle and more, Quai is excited to usher in a new generation of innovative applications that don’t sacrifice decentralization.

Offchain Labs and Espresso Systems Partner to Bring Transaction Ordering Technology to Ethereum Rollups

Published

on

Today, Espresso Systems and Offchain Labs announced that they have formed a partnership towards bringing decentralized and open shared sequencing technology to Ethereum rollups. The collaboration will see the teams undertake joint research on Timeboost, a transaction-ordering design previously proposed by Offchain Labs, and will support technical integrations between the Arbitrum technology stack, Timeboost ordering, and the Espresso Sequencer.

Espresso Systems is the lead developer of the Espresso Sequencer, a platform designed to decentralize sequencing for Ethereum rollups, offering developers and users across different rollups a more seamless and secure path to interoperability while maintaining the fast response time available to users today. Espresso Systems, with the support of Offchain Labs, is now prioritizing integration with the Arbitrum technology stack, aiming to support any Arbitrum technology chain that chooses to leverage its decentralized, shared sequencer platform including support for distributed Timeboost ordering.

Timeboost is a new transaction ordering policy designed by Offchain Labs that relies on sealed-bid priority gas auction ordering. The Timeboost system limits harmful forms of MEV (frontrunning) while supporting efficient markets allowing chains to internalize other forms of MEV like backrunning. Timeboost prioritizes user experience and ensures the timely processing of all user transactions. In collaboration with the Offchain research team, Espresso Systems will develop a production-ready, open-sourced, and distributed implementation of Timeboost that can be adopted by any network, including any Arbitrum chain and can integrate directly with the Espresso Sequencer.

The Espresso Sequencer itself is a consensus protocol that supports proposer-builder separation (PBS). This enables other advanced transaction ordering policies to be implemented at the builder level, such as MEV auctions and rebate protocols like SUAVE. Rollups can choose to enshrine a builder protocol (like Timeboost) or, by default, use PBS. Espresso Systems is glad to lend its research and development resources to support a variety of ordering approaches that align with user needs, such as Timeboost.

The Espresso Sequencer recently released its third testnet and currently supports the OP Stack, the Polygon zkEVM stack, and has a dozen independent rollup teams working on integrations with the technology. Support for the Arbitrum technology stack will enable Arbitrum chains to integrate with the Espresso Sequencer and further Espresso’s implementation of a neutral and open protocol that is compatible with all of Ethereum’s rollups.

Ben Fisch, co-founder and CEO of Espresso Systems, said of the partnership: “We are excited to have Offchain Labs’ support in bringing an open, freely accessible shared sequencing platform to all ecosystems on Ethereum and it is a pleasure to partner with their team to improve user experience on rollups as we innovate on transaction ordering policies. Offchain Labs has pioneered many of the breakthroughs behind the most widely-adopted scaling solutions in the industry, and it is a privilege to partner deeply with them.”

“We’re thrilled to work with the Espresso team on researching Timeboost and bringing shared sequencing technology more broadly to Ethereum rollups,” added Steven Goldfeder, Co-founder and CEO of Offchain Labs. “The technology will enable fair and efficient ordering policies and open possibilities for deeper integrations among rollups which opt to participate in shared sequencing.”

Offchain Labs and Espresso Systems will be sharing a roadmap soon for their research and implementation of the Timeboost builder module and for the ability to integrate the Espresso Sequencer with Arbitrum technology chains. The two teams look forward to the advancement of the partnership as they share a vision for the decentralized, and user-aligned future of shared transaction sequencing on Ethereum rollups.

Follow along with the work @OffchainLabs and @EspressoSys on Twitter and on the Arbitrum Research Forum for more.

About Espresso Systems

Espresso Systems is the lead developer of the Espresso Sequencer, a platform offering decentralization, speed, scale, and interoperability to rollups. The Espresso Sequencer currently has testnets that are compatible with the OP Stack and the Polygon zkEVM ecosystems with 10+ rollup teams actively building integrations. Espresso Systems is backed by over $30mm from funds including Electric Capital, Greylock, and Sequoia.

Alchemy Pay Deploys on Polygon zkEVM as an Early Stage On-Ramp Provider

Published

on

Alchemy Pay is deploying its payment services on Polygon’s new zkEVM chain, to be one of the first fiat-crypto on-ramp providers to support the zkEVM ecosystem. Users of the network from all over the globe can now purchase cryptocurrencies using their preferred local fiat payment methods.

Developers building on the new zero-knowledge proof network can now benefit from Alchemy Pay’s direct-to-customer plugin, which can be easily integrated and deployed by dApps and platforms with minimal cost and hassle. Alchemy Pay has supported tokens and projects on Polygon mainnet since 2021, and as one of the world’s premiere fiat-crypto payment gateways, it has been selected as one of the first ramp providers to integrate its on-ramp service on Polygon’s new chain.

“It’s exciting to see projects like Alchemy Pay help to improve the onboarding and usability of the Polygon zkEVM blockchain” Jack Melnick, Head of DeFi BD at Polygon Labs, “Alchemy Pay truly acts as a user-friendly gateway to the crypto spaces for users. The Polygon zkEVM ecosystem is very excited for this deployment.”

Polygon zkEVM Architecture & Benefits

Polygon zkEVM is an Ethereum Layer 2 scalability solution that uses cryptographic zero-knowledge proofs to offer validity and quick finality to off-chain transaction computation, also known as a ZK-Rollup. Developers on Polygon zkEVM can use the same code, tooling, apps, etc that they use on Ethereum, but with higher throughput and lower fees.

The ZK-Rollup executes smart contracts transparently, by publishing zero-knowledge validity proofs, while maintaining opcode compatibility with the Ethereum Virtual Machine. This documentation explains the finer details of zkEVM’s sub-components, including the zero-knowledge Prover (zkProver), the State Machines used in the zkProver, the zkEVM Bridge smart contract, and the special toolings that enable the Polygon zkEVM to achieve its objectives.

Developers are able to deploy their existing smart contracts to the zkEVM, and users can deposit assets from Ethereum and transact off-chain. These transactions are grouped into batches with zero-knowledge proof attesting to the validity of each transaction. This means the network inherits the security of Ethereum.

Alchemy Pay: Truly Global Fiat-Crypto Services

Alchemy Pay’s payment gateway enables payments using Visa, Mastercard, Discover, and Diners Club across 173 countries, along with domestic transfers and mobile wallets in developing markets. Its user-friendly KYC process, low fees, and exceptional conversion rates make buying and selling cryptocurrencies with local currencies as convenient as any typical online payment.

zkPass pre-alpha testnet opens for public testing

Published

on

In a significant stride towards revolutionizing data privacy and verification, zkPass, the innovative privacy-preserving protocol for private data verification, announces that its Pre-alpha Testnet is open for public testing.

A Glimpse into the Future: zkPass Pre-alpha Testnet

The zkPass Pre-alpha Testnet presents a transformative approach to private data verification. Built on the bedrock of Multi-Party Computation (MPC), Zero-Knowledge Proofs (ZKP), and Three-party Transport Layer Security (3P-TLS), zkPass introduces TransGate—a gateway empowering users to selectively and privately validate their data from any HTTPS website. This encompasses diverse data types, including legal identity, financial records, healthcare information, social interactions, work history, education, and skill certifications. zkPass achieves these verifications securely and privately, obviating the necessity to reveal or upload sensitive personal data to third parties.

The Power of Scalability

zkPass can be readily incorporated into multiple application scenarios, including composable decentralized identity passes, DeFi lending protocols based on off-chain credit, privacy-ensured healthcare data marketplaces, and dating apps featuring verifiable zkSBTs, etc. Wherever there is a need for trust and privacy, zkPass can provide a solution.

By employing cryptographic technologies like MPC, ZKP, and others, zkPass enables users to validate their private data through the verification of their HTTPS-based web session—eliminating the need for file uploads or the exposure of sensitive details.

For example, through zkPass, Alice can prove:

  • Based on her server response to the Steam/GOG website, she has purchased 10+ games with 100+ hours of gameplay and is not required to disclose any other private information about her account to a third party.
  • Based on her server response with the Harvard Alumni website, she has a Bachelor’s degree and is an alumnus of Harvard University, but does not disclose any of her other superfluous personal data.
  • Based on her server response with the Porsche website, she owns a Porsche, but does not disclose her frame number, purchase order, or other private data.
  • Based on her server response with the bank’s website, she owns assets greater than $100K, but does not disclose any of her specific account assets, transfer records, or other private data.

zkPass can be applied in various scenarios to enhance user experience, trust, and privacy:

  • The Metaverse/GameFi program is looking for gaming ambassadors to participate in a test and offer a reward, and they can easily verify that Alice is their target user.
  • Alice can seamlessly access the Alumni DAO via her zkPass zkSBT while ensuring privacy and trustworthiness.
  • Alice leveraged her RWA ZKPs to establish a reputation for high ratings, which allowed her to access a DeFi lending platform and secure lower mortgage and borrowing rates, ultimately boosting her capital efficiency.

By redesigning the TLS protocol to Three-party TLS, zkPass makes it seamless for any HTTPS-based website to be used as a trusted data source for provenance of zero-knowledge metadata without having to authorize any APIs.

Open Invitation to Shape the Future

zkPass launched its Pre-alpha Testnet in July, receiving an overwhelming response with over 200,000 waitlist signups.

Offchain Labs Brings Multi-Language Support via Arbitrum Stylus

Published

on

Offchain Labs, the initial contributor to Arbitrum, today released the code and testnet for Arbitrum Stylus, a new technical implementation that allows developers to build smart contracts in Rust, C, and C++, alongside previously offered EVM languages. Multi-language support encourages developers to build on Arbitrum Nitro, the leading scaling solution for Ethereum, by utilizing the familiar WASM-compatible languages and facilitating cheaper dApp interactions due to lower gas costs. Offchain Labs will make Stylus available to the Arbitrum DAO for a vote on adoption of the tool.

For software engineers looking to enter the blockchain space, a constant barrier to entry is the limited number of languages in which they can code. Currently, there are estimated to be 3 million developers using Rust and 12 million developers using C, both of which will now be available via Stylus, compared to approximately 20 thousand developers using Solidity. Stylus removes this barrier by letting programmers use one chain with various programming languages alongside the unparalleled security, maturity, and scalability of Arbitrum technology. An entire new class of developers can now access the largest community of protocols and partners in the Ethereum ecosystem.

“Growing and building the most inclusive developer community is incredibly important to us,” commented Steven Goldfeder, CEO and Co-Founder of Offchain Labs. “We want to open access for as many people as possible to create new applications and there is uncapped potential for innovation on the chain and technology stack. I look forward to a continuously flourishing ecosystem and collaborative community that will push the Web3 space forward.”

Blockchain use cases that were previously impractical will now be possible due to Stylus’ computational speed, improved cost efficiency, and access to the mature WASM ecosystem. Having a faster runtime than the EVM, WASM results in a faster execution – generally, a 10x improvement has been seen for contracts using WASM languages compared to contracts using EVM-based Solidity. Cryptography, mobile applications, high-compute gaming, and AI projects are specifically primed to take advantage of Stylus’ language flexibility and improved computational efficiency. Additionally, Stylus will offer security benefits to avoid exploits, as reentrancy is disabled by default and can only be manually overridden.

In the future, any systems programming language that can compile to WASM is expected to be supported. While there are other blockchains execution environments that support a WASM virtual machine, Arbitrum’s Stylus upgrade is unique as it is a dual virtual machine that can process both EVM and WASM contracts while also maintaining interoperability and provability over Ethereum.

Maximizing earnings from liquidity provision and strengthening the Arbitrum ecosystem

August 31, 2023 — Yield IQ, the revolutionary liquidity provision tool that seeks to unlock new revenue streams for cryptocurrency token holders, is now live on the Arbitrum chain. Developed by a team of visionary developers and innovators in the DeFi space, Yield IQ limits impermanent loss and opens up new possibilities for individuals to effortlessly earn through liquidity provision.The launch presents an unprecedented opportunity for token holders, decentralized autonomous organizations (DAOs), and other DeFi projects to maximize their earnings through Yield IQ’s innovative strategies of yield optimization and liquidity management—while actively contributing to the growth and resilience of the broader Arbitrum ecosystem.

Arbitrum was chosen for this latest launch due to its scalability and efficiency, which will allow Yield IQ to maximize performance and better empower liquidity providers to generate substantial returns with improved liquidity, reduced costs, and enhanced trading opportunities. Yield IQ Vaults are also available on the Ethereum and Polygon networks.

Among the myriad benefits, Yield IQ’s introduction to the Arbitrum chain offers liquidity providers:

  • Improved Liquidity: Pairing Arbitrum tokens (ARB) with another token of choice can both enhance liquidity and foster a healthier, more vibrant ecosystem.
  • Additional Earnings for DAOs: When a Yield IQ deposit widget is integrated to a partner’s frontend paired with Chainlink Automation, projects become eligible for an additional 5% of the trading fees generated by the token’s pool. These earnings flow directly into the users’ DAO treasury, strengthening their financial position.
  • Lucrative Returns: To ensure a promising investment opportunity for DAOs seeking stable and reliable returns, Yield IQ offers a 25% Internal Rate of Return (IRR) for ARB deposits paired with ICHI over the next 12 months, backed up with up to 50k ICHI tokens.

“Right now, arbitrage traders are winning the battle over liquidity,” said Coburn Murray, CEO of values-driven investment firm Ethos Capital. “For most providers, it is not profitable or practical to ensure liquidity. Yield IQ, however, empowers providers to earn the most from their deposits, and we are excited to partner with the Arbitrum community to deliver optimal results and trading opportunities.”

Developed and launched by Offchain Labs in August 2021, Arbitrum was designed to improve transaction speeds, enable scalability and ensure increased network privacy. The ecosystem sparked industry conversations earlier this year by airdropping $120 million worth of tokens to projects built on its network—and, in the process, both highlighting the potential for blockchain projects to utilize incentives and rewards for participation.

Since inception, Yield IQ has achieved remarkable success—boasting a median 30% annualized return on Polygon and partnering with Retro—a leading ve(3,3) DEX and a new automated liquidity management marketplace. By accessing Yield IQ via Retro’s front end, users are able to lock their tokens for voting and gain influence over emission destinations, earning fees and rewards from the pools they support. This incentivizes users to thoughtfully consider their votes and helps steer the DEX in the right direction, promoting a community-driven ecosystem.

Yield IQ efficiently deploys liquidity to Uniswap V3 concentrated liquidity pools. With a single token deposit, projects can passively earn returns while the algorithm actively manages their preferred token and generates trading fees from liquidity pools. By leveraging a fully automated, on-chain liquidity provision strategy, Yield IQ enables liquidity providers to mitigate common challenges in generating consistent profits, capital inefficiencies, and a lack of expertise in liquidity provision strategies.

The launch on Arbitrum further strengthens Yield IQ’s commitment to empowering users and contributing to the growth and resilience of the broader DeFi ecosystem. When ARB tokens are deposited into Yield IQ Vaults, token holders contribute to the strength and growth of the entire Arbitrum ecosystem. This means more stable prices, more efficient trades, and a wealth of opportunities for projects to flourish.
