The UI was reworked to allow for multiple pools on multiple chains. The first pool to be released is the ETH pool on Optimism, where both ETH and WETH can be deposited via different methods.
ETH deposits use a different method for deposit (direct deposits). These can take longer, and pending display was added to provide users with additional information during an ETH deposit.
Support was added to allow for new token pools, including support for the upcoming BOB - USDC migration on Polygon. Permit2 and TransferWithAuthorization (aka EIP-3009) standards were implemented.
