# Uniswap Contracts

<Info>
  The latest versions of Uniswap v4 and v3 contracts are deployed at the addresses listed below, on both Celo mainnet and the Celo Sepolia testnet. Integrators should no longer assume that they are deployed to the same addresses across chains and be extremely careful to confirm mappings below.
</Info>

## Uniswap V4 Contracts

Uniswap v4 introduces a new modular architecture with hooks and singleton pool manager design. The core contracts are deployed on Celo mainnet and on the Celo Sepolia testnet.

<Note>
  On Celo Sepolia the `UniversalRouter` and `PositionManager` use the CELO ERC-20 (`0x471EcE3750Da237f93B8E339c536989b8978a438`) as their wrapped-native (`weth9`) slot, matching Celo mainnet. CELO does not implement `deposit()` / `withdraw()` on the L2, so the router's `WRAP_ETH` / `UNWRAP_WETH` commands will revert. Pools using the native asset (`address(0)`) or CELO as an ERC-20 are unaffected.

  Two test routers (`PoolSwapTest` at [0x42592B9fFA3be9351cf06EC499e28b88a4A99f50](https://celo-sepolia.blockscout.com/address/0x42592B9fFA3be9351cf06EC499e28b88a4A99f50), `PoolModifyLiquidityTest` at [0x643ddc282cD4C65a40cd96c27968B63a2e31cF6d](https://celo-sepolia.blockscout.com/address/0x643ddc282cD4C65a40cd96c27968B63a2e31cF6d)) are also deployed on Celo Sepolia for convenience.
