Pegasys Swap Router
This repository contains smart contracts for swapping on the Pegasys V1 and V3 protocols.
Local deployment
In order to deploy this code to a local testnet, you should install the npm package
@pollum-io/swap-router-contracts
and import bytecode imported from artifacts located at
@pollum-io/swap-router-contracts/artifacts/contracts/*/*.json
.
For example:
import {
abi as SWAP_ROUTER_ABI,
bytecode as SWAP_ROUTER_BYTECODE,
} from '@pollum-io/swap-router-contracts/artifacts/contracts/SwapRouter02.sol/SwapRouter02.json'
// deploy the bytecode
This will ensure that you are testing against the same bytecode that is deployed to mainnet and public testnets, and all Pegasys code will correctly interoperate with your local deployment.
Using solidity interfaces
The swap router contract interfaces are available for import into solidity smart contracts
via the npm artifact @pollum-io/swap-router-contracts
, e.g.:
import '@pollum-io/swap-router-contracts/contracts/interfaces/ISwapRouter02.sol';
contract MyContract {
ISwapRouter02 router;
function doSomethingWithSwapRouter() {
// router.exactInput(...);
}
}
Tests
Some tests use Hardhat mainnet forking and therefore require an archive node.
Either create a .env
file in the workspace root containing:
ARCHIVE_RPC_URL='...'
Or set the variable when running tests:
export ARCHIVE_RPC_URL='...' && npm run test
