Optimism supports ERC-7683

This standard was created by Across Protocol in collaboration with Uniswap and provides a framework for cross-chain actions based on intents. This unlocks better UX for users, easier swaps, and shared liquidity. Support for this standard pushes forward interoperability between the Superchain and Ethereum as a whole.

Fault proofs are live on Base

Anyone can monitor and permissionlessly challenge invalid withdrawals, removing the need for a trusted third party and paving the way for greater community participation. With this, Base moves closer to Stage 1 decentralization, although a Security Council and modifications in the approval process for Base protocol upgrades are still needed. Base is on track to reach Stage 1 in the coming months.
