A grant update for the development of ChainHopper, enabling single-click migration of Uniswap LP positions between EVM chains and supporting liquidity migration to Unichain and Uniswap v4.

Today, moving an LP position between chains requires multiple separate steps: removing liquidity, bridging each token individually, waiting for confirmations and recreating the position on the destination chain. To help users optimize their LP positions, the Uniswap Foundation committed $235,000 to Melio to develop ChainHopper, an LP migration protocol, currently live on Mainnet, Unichain, Base, Arbitrum and Optimism.

"We built ChainHopper to move - what I consider to be perhaps the most common 'composed' asset on-chain - Uniswap LP Positions. 10M+ have likely been created across a dozen chains. Instead of liquidity stuck in an inefficient pool, it can easily migrate to a more vibrant part of the on-chain ecosystem" says Aseem Sood, ChainHopper’s lead contributor.

ChainHopper converts the existing 5-step manual process into a single transaction, handling both tokens in an LP position simultaneously while abstracting away gas requirements on destination chains.

Features include:

• Single Transaction Flow: One-click migrations

• Multi-Asset Bridging: Handles both tokens in an LP position simultaneously (via Across Protocol)

• Gas Abstraction: Destination chain gas tokens not required

• Protocol Flexibility: Supports v3 → v3, v3 → v4, and v4 → v4 position transfers, including v4 hooked pools

• Tooling: For easy integrations

We’re excited to see how ChainHopper can improve liquidity mobility for the Uniswap ecosystem. If you're building platforms that manage LP positions, developing cross-chain DeFi interfaces, or working on Unichain integrations, ChainHopper can help.

The SDK is audited and ready for production integration today, try it out below:

A demo frontend focused on Unichain LP migrations is launching within the next few weeks.
