Uniswap and Across announced a partnership yesterday to power permissionless cross-chain swaps for the former.

With the rapid sprout of L2 rollups in recent years, trading cross-chain has proven increasingly frustrating as users have to manually bridge assets to different chains in order to trade specific assets or take advantage of deeper liquidity elsewhere.

The integration of Across’s intent-based bridging now allows traders to easily bridge and perform cross-chain swaps, all within Uniswap.

Across Protocol is built by Risk Labs, the team also behind the Universal Market Access (UMA) optimistic oracle.

Based on Risk Labs’ Dune dashboard, Across has bridged a cumulative $12.7 billion in lifetime volumes, with about $20-40 million in daily volumes over the last week.

According to Across’s blog, its bridging infrastructure is a “…robust, intents-powered solution that aims to execute certain L2-to-L2 transfers in just 3 seconds for transactions under $10,000 — which represent 99% of all L2 bridging activity.”

Nine EVM chains are included in the Across integration, which went live yesterday: Ethereum, Base, Arbitrum, Polygon, OP mainnet, Blast, ZKsync, Zora and the just-announced World Chain.

Initially supported tokens will include stablecoins, WBTC, and any native chain assets i.e., OP on Optimism, ARB on Arbitrum or ETH on Ethereum.

Uniswap and Across co-developed ERC-7683, a new cross-chain intent-centric token standard that would make it easier for cross-chain transactions to be executed by intermediary solvers/relayers on different chains.

As explained by Across CTO Nicholas Pai, ERC-7683’s goal “…is to shrink the scope of the problem so that Bridges and DEXs can use the standard today while maintaining composability with existing messaging networks.”

For Uniswap’s upcoming L2, Unichain, ERC-7683’s planned use is to enable cross-chain swaps for blockchain networks that fall outside of Optimism’s network of blockchains, dubbed the Superchain.
