• Safe supports multichain address deployments.

• Lido’s Community Staking Module goes live.

• Velodrome expands its MetaDEX to Superseed.

Safe introduced a new feature that allows users to reserve a smart wallet account with the same address across 15 supported networks. Now live on the Safe user interface, the feature allows users to reserve their address in a single click. Once reserved, the address can receive funds and the smart contract can be deployed at any time. Safe also offers sponsored transactions on networks like Gnosis, Polygon PoS, Polygon zkEVM, Base, OP Mainnet, Arbitrum, Linea, and Blast, enabling wallet deployments without requiring native gas tokens. The release includes a new sidebar interface that simplifies switching between multiple accounts. The feature is compatible only with Safe version 1.3.0 or later.

Lido’s Community Staking Module (CSM), a permissionless staking solution that allows node operators to run validators through the Lido protocol, is now live on mainnet. The module lowers the barrier for solo stakers by allowing participation with a collateral stake of 2.4 ETH for the first validator and 1.3 ETH for additional validators. The launch is an early adoption phase initially available to qualified solo stakers. Lido states that operators using CSM can earn up to 2.37x higher rewards compared to traditional solo staking. As a key component of the Lido Staking Router, a controller contract designed to integrate modular validator pools, the CSM enables node participation from solo stakers, DAOs, and DVT clusters.

Velodrome announced plans to launch support for Superseed on the Velodrome Superchain, a MetaDEX serving as the primary liquidity hub on the Superhain. Superseed is a DeFi-focused protocol built on the OP Stack that features a native collateralized debt position system called SuperCDP. SuperCDP allows users to lock assets as collateral to mint and borrow the Superseed stablecoin, enabling access to interest-free, self-repaying loans. veVELO holders will be able vote and direct emissions towards liquidity gauges on Superseed's L2. Superseed will also provide incentives for the launch. The Velodrome Superchain already includes nine OP Stack chains.

Kraken introduced Ink, a new Layer 2 built on the OP Stack, designed to streamline access to DeFi and onboard users onchain by connecting Kraken’s centralized services with a decentralized ecosystem. Ink will feature 1-second block times, settle transactions on Ethereum, and is being developed with the Gelato Network RaaS platform. Similar to Coinbase’s Base, Kraken anticipates migrating its infrastructure onchain. As a member of the Superchain, Ink will support interoperability, governance standards, and shared upgrades and contribute a portion of its sequencer revenue to the Optimism Collective. The testnet launch is scheduled for November 2024, with the mainnet launch expected in early 2025. Users can currently mint a commemorative NFT on OP Mainnet.

Arbitrum Orbit, a tech stack for building L2 and L3 chains, now supports fast withdrawals, enabling withdrawals transactions to be finalized in as little as 15 minutes for Orbit L2 chains and 15 seconds for Orbit L3 chains. Optimistic Rollups typically require a seven-day challenge period for fraud proofs, leading to long withdrawal periods. Fast withdrawals are initially available for Arbitrum Orbit chains built using the AnyTrust architecture and rely on a Data Availability Committee (DAC). The implementation is facilitated through a committee-based validation process. Arbitrum Orbit chains that meet the prerequisite criteria can customize their own withdrawal configurations.

Synthetix Perps V3 is now live on Arbitrum One through the Kwenta interface with support for 81 new markets. Synthetix V3 introduces multi-collateral support, cross-margin trading, account-based access controls, and improved liquidation mechanisms, allowing traders to use their entire portfolio as collateral across multiple positions. Supported collateral types include ETH, tBTC, USDx, and USDe. Kwenta features one-click gasless market orders, integrated bridging via Socket, and delegated wallets. According to DefiLlama, Synthetix V3 on Arbitrum currently holds about $8.5 million in TVL.

Uniswap integrated support for permissionless bridging across nine networks directly into the web app and mobile wallet. Users can access a new “Swap across networks” option within the swap interface, allowing them to seamlessly bridge native assets and stablecoins by selecting their preferred input and output networks. This functionality is powered by Across Protocol, a permissionless cross-chain bridge protocol that leverages liquidity pools and relayers for fast, secure transactions. Uniswap and Across are also co-developers of the ERC-7683 cross-chain intents standard, a standard that expands the range of order fillers available to execute user intents.

Base announced that Fault Proofs will go live on mainnet on October 30th, 2024. The upgrade introduces permissionless output proposals and permissionless challenges, empowering anyone to submit state claims about the chain and challenge fraudulent withdrawals. The activation brings Base to Stage 1 decentralization. In Stage 1, rollups are equipped with functional proof schemes and a multi-sig override mechanism, such as the Security Council. Bridge operators on Base are advised to notify their users and update their bridging logic to align with the new contracts. Optimism first implemented Fault Proofs on OP Mainnet earlier this year in June 2024.

Optimism unveiled the first participants in its OP Chain Delegation Program, an initiative that allocates OP token delegations to OP Stack chains to encourage their involvement in Optimism governance. The program grants between 250,000 and 1.5 million OP to eligible chains, equipping them with sufficient governance power to approve or reject proposal drafts. Among the first recipients are Cyber Network and Mint, both OP Stack chains. Each delegation is active for 12 months, providing the chains with a boost while they grow their user-based delegations organically. To maintain eligibility, participating chains must uphold a voting participation rate above 70% throughout the delegation.

Conduit, a rollup-as-a-service provider, released a research post analyzing the cost per MB of data availability across Ethereum blobs, Celestia blobs, and Celestia SuperBlobs. Developed through a partnership between Celestia and Conduit, SuperBlobs enable rollups to publish larger data batches on Celestia. The study found that the average data availability cost was $20.56 per MB on Ethereum mainnet, $7.31 per MB on Celestia, and less than $1 per MB using SuperBlobs.
