Infrastructure service provider Conduit introduced support for deploying Arbitrum Orbit Layer 3 chains using Base as the settlement layer. Conduit's rollup-as-a-service platform offers customizable rollup configurations, granting teams the ability to configure the rollup framework, data availability solution, and settlement layer options. Arbitrum Orbit is a tech stack for the deployment of L3 appchains on Arbitrum AnyTrust chains and features the capability to use custom gas tokens. The L3 chains are designed to reduce computational costs and provide dedicated block space. Conduit offers the deployment of L3 chains on either the testnet or mainnet.

Over 16 ecosystem projects joined forces to launch unblockcrypto.org, an initiative seeking to further adoption of EIP-6963, a standard for wallet connection to dapps. EIP-6963, which was finalized in October 2023, enables the discovery of multiple injected wallet providers and addresses existing conflicts with EIP-1193 wallets. Wallet extensions load in an unpredictable sequence when multiple wallets are installed. Zerion, WalletConnect, Rainbow, MetaMask, and Coinbase Wallet, among others, now support EIP-6963 to address this issue. Users can participate in the unblock crypto initiative by minting a commemorative NFT, with proceeds going to EIP authors.

Velodrome, an Optimism-native DEX , launched Slipstream, a new concentrated liquidity AMM designed for low-volatility and high-volume token pairs. Slipstream aims to capture a bigger share of daily trading volume on Optimism. Concentrated liquidity pools provide liquidity providers with exposure to higher volume and fees. LPs on Velodrome can now deposit into clAMM pools with VELO emissions ramping up in the coming weeks. The Slipstream implementation is based off of UniV3. The clAMM features a fee algorithm that adjusts according to market volatility. Velodrome is the largest DEX on Optimism by TVL with over $140 million in assets.

Base announced that its Layer 2 rollup will support the Dencun upgrade from day one. Dencun represents the next upgrade for Ethereum, featuring EIP-4844, a proposal that dramatically lowers the data availability costs for rollups by up to 99%. The Dencun upgrade is scheduled to activate on Ethereum-mainnet on Wednesday, March 13th, at 13:55:35 UTC. Dencun will be implemented on OP Stack chains shortly after as part of Optimism’s Ecotone upgrade. Coinbase has played a role in contributing to the core development of EIP-4844.

OP Labs released a bond-based dispute game mechanism design for the OP Stack. Dispute games are used to facilitate fault detection in a fault-proof system. The proposed mechanism design encourages honest participation by imposing a bond requirement on claims, penalizing dishonest claims with a cost barrier. "Big Bonds" are the initial strategy, setting high ETH-denominated bonds adjusted for gas costs and claim depth to cover costs for honest participants and deterring spam. The fault dispute game marks a step towards further decentralizing the OP Stack through implementation in a future protocol update.

SEC Commissioners Hester M. Peirce and  Mark T. Uyeda issued a statement in regard to enforcement action against crypto exchange ShapeShift. The SEC filed a cease and desist against ShapeShift for not registering as a securities dealer between 2014 and 2021. ShapeShift settled the charges and paid a $275,000 fine. Commissioner Peirce criticized the order for not specifying which assets were deemed securities and the reasoning behind it. She highlighted the ongoing ambiguity surrounding the definition of a security, noting that this uncertainty undermines innovation and places entrepreneurs in a difficult position due to the absence of clear regulatory guidelines.

The Wormhole multichain bridge introduced an eligibility checker tool for its $W token airdrop. The W token has a total supply of 10 billion, and 6.17% of this supply is dedicated to the community airdrop. Users can check their eligibility and W token allocation by checking their wallets across EVM, Sei, NEAR, Kujira, and Evmos chains. The airdrop is based on a snapshot captured on February 6. The distribution of the W token will be in both ERC20 and SPL formats, covering several chains such as Ethereum, Solana, Arbitrum, Optimism, and Base. The criteria for eligibility include interactions with applications within the Wormhole ecosystem, stakers, and certain NFT communities. The W token has not yet been launched.

Rollup-to-rollup bridge Hop Protocol will now support Circle’s Cross-Chain Transfer Protocol (CCTP). Users will be able to bridge native USDC across supported networks on Hop. The Cross-Chain Transfer Protocol allows USDC to be natively burned on a source chain and natively minted on a destination chain, removing the need for USDC liquidity providers on the bridge.

• Snapshot introduces Boost rewards.

• Fraxtal’s native bridge goes live.

• Fluidkey introduces the Stealth Account Kit.

• Astar Network launches the Astar zkEVM.

Snapshot, an offchain governance voting platform, introduced Boost, a new feature that allows DAOs to incentivize voting participation by rewarding voters with ERC-20 tokens. The feature allows DAOs to select a token and amount for the voter rewards, choose between lottery or proportional distribution mechanisms, and define eligibility parameters. DAOs can also customize winning prababliities and set caps for an upper limit for large token holders. Boost is currently available in a private beta release for select DAOs. Snapshot hopes that the new feature will help address voter apathy in cases where only a small subset of token holders vote on DAO proposals.

The Fraxtal native bridge is now live on mainnet, enabling deposits of ETH, CRV, sfxETH, and various tokens from the Frax ecosystem directly to Fraxtal. As a Layer 2 network built on the OP Stack, Fraxtal introduces a novel incentive mechanism called Flox, rewarding users and developers with FXTL points based on their gas spend. Frax Finance is also offering FXTL point rewards for FXS stakers. Fraxtal is also part of Optimism’s Superchain collective, supporting shared upgrades and a commitment to public goods funding. Frax Ether (frxETH) serves as the rollup’s native gas token. Fraxtal currently holds just over $1 million in frxETH deposits.

Transaction privacy tooling provider Fluidkey introduced the Stealth Account Kit, an open-source TypeScript library that offers the essential cryptographic functions for generating and recovering Fluidkey stealth accounts. The release aims to promote the development of privacy-focused applications. The library is influenced by Umbra.js, viem, and Safe. The library's functionalities cover generating private keypairs from signatures, extracting and generating private viewing keys, creating stealth addresses, and predicting stealth Safe addresses. Fluidkey automatically directs payments sent to a private ENS to a new address that only the user can control. Users can currently sign up for a waitlist to use the privacy tool.

Astar Network launched its Astar zkEVM on mainnet, built on the Polygon CDK and integrated with the AggLayer. The implementation enables Astar to access unified liquidity across ZK-powered chains on Polygon through a single bridge. The rollup was built in collaboration with automation infrastructure provider Gelato Network.
