This tool doesn't deploy V3 Swap Router

[alexeyyakimovich]

I'm going through this tutorial: https://docs.uniswap.org/contracts/v3/guides/swaps/single-swaps

I want to test full scenario in my private testnet.

Using this tool i'm only get V2 Swap Router.

We have just run across this issue (or similar) as well. The SwapRouter contract deployed appears to be from the swap-router-contracts repo using this interface which is missing the deadline variable.

It is unclear to me if the swap-router-contracts repo is deprecated, but the v3-periphery repo also has this interface - named a little differently but it is the interface that matches what is deployed to Ethereum L1 networks.

Given this mismatch, our experience with deploy-v3 is that it produces deployments that are incompatible with those on L1. Will try out the hardhat version, but the "official" documents on new chain deployments reference this codebase.

So, what is the final conclusion？ We cann't deploy SwapRouter ? why?

If we want to call contract swapRouter.exactInputSingle directly on celo, we must use the correct abi:
import SwapRouter02Abi from '@uniswap/swap-router-contracts/artifacts/contracts/V3SwapRouter.sol/V3SwapRouter.json' assert {type: 'json'} , and the params object for exactInputSinglem method need not have deadline properties. That means params should have 7 properties, not 8. See also How to swap Celo tokens on Uniswap programmatically with code , this example has 2 bugs, which have mentioned above.

Other wise, if we want to use js function swaprouter.swapCallParameters on celo, we must create a ts file which is named swapRouter02.ts : copy this code to swapRouter02.ts , then delete all the deadline properties, and use the correct abi:
import SwapRouter02Abi from '@uniswap/swap-router-contracts/artifacts/contracts/V3SwapRouter.sol/V3SwapRouter.json' assert {type: 'json'}
