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.
