Uniswap Labs, the company behind decentralized exchange Uniswap, announced the launch of its permissionless bridging feature powered by Across Protocol.
In an Oct. 23 blog post, Uniswap said that its user base of over six million people would be able to swap on multiple chains directly from the Uniswap Interface and Uniswap Wallet.
The feature allows users to bridge assets across nine networks: Ethereum, Base, Arbitrum, Polygon, OP Mainnet, Zora, Blast, World Chain and ZKsync. Only native assets and stablecoins will be supported from bridging at launch.
“In-app bridging is one of our most requested features, and we’re excited to roll it out as a step toward our long-term vision of cross-chain swaps,” said the Uniswap team.
Across Protocol founder Hart Lambur noted on X that the ETH and stablecoins can be bridged between layer 2 networks with an average fill time of three seconds.
Across operates through a single-sided liquidity pool and relayers, using an intents-based framework that allows users to specify their desired outcome rather than the exact steps to achieve it. The protocol also leverages UMA’s optimistic oracle for security and transaction verification.
“The proliferation of rollups has solved scalablity but has introduced a new challenge: Ethereum is fragmented. To fully realize Ethereum’s vision, we must unify these chains, creating a seamless and FAST experience for users across all of Ethereum’s rollups,” said Lambur.
“A 2-second interop experience is essential for the next billion users to truly unlock DeFi, gaming, social apps, and more.”
