What is Chainhopper?
Chainhopper moves complex assets like Uniswap LP positions between different EVM chains. Instead of unwinding an LP position and moving individual tokens manually, Chainhopper does it all in one go.

How does Chainhopper work?
Chainhopper works by moving the entire LP position as a single asset. It burns the LP position to extract both assets (and uncollected fees) and sends either both or one asset via Across to the destination chain. On desination chain, it receives asset and constructs a new position based on parameters encoded in the bridge transfer.

What type of positions can Chainhopper move?
Chainhopper can move any Uniswap V3 and V4 LP positions where one token is ETH or WETH.

Chainhopper can move any Uniswap V3 and V4 LP positions where one token is ETH or WETH.
What happens if a migration fails midway?
If a migration fails on source chain, the entire transaction will revert and your original LP position will be untouched. If a migration fails on destination chain, you'll receive the tokens directly to your wallet and can use them to construct a position manually. In that scenario, there will be no fees charged.

How do fees work?
Chainhopper protocol charges a 0.1% fee on all successful transfers. If a transfer fails to deliver an LP position on destination chain (and you receive ETH instead), there is no fee.

How long do transfers take?
Usually a few seconds with reasonable slippage values (like 1%)

What is the maximum size of an LP position that Chainhopper can move?
Chainhopper is only limited by the capacity of bridges to move assets efficiently. As long as a bridge supports it and pools have enough liquidity (for swaps), Chainhopper can move the position. While we are in the auditing face, we have limited Chainhopper to only move positions less than $1000.
