ABIs

ABIs for every DEX-side contract you might call live in integrator-kit/abis/ (13 files):

Contract	File
ERC-20	ERC20.json
Uniswap V3 Factory	UniswapV3Factory.json
Uniswap V3 Pool	UniswapV3Pool.json
NonfungiblePositionManager	NonfungiblePositionManager.json
SwapRouter02	SwapRouter02.json
UniversalRouter	UniversalRouter.json
QuoterV2	QuoterV2.json
TickLens	TickLens.json
Permit2	Permit2.json
Multicall	Multicall.json
Multicall2	Multicall2.json
V3 Migrator	V3Migrator.json
UniswapV3Staker	UniswapV3Staker.json

For launchpad contract ABIs (the Fire* contracts), build the fire repo with forge build - the artifacts land in fire/out/.

Regenerating

The integrator-kit has a script that regenerates ABIs from upstream artifacts:

cd integrator-kit
pnpm fetch-abis

The same repo also has scripts/compare-bytecode.ts for verifying that the deployed contracts match the upstream Uniswap V3 bytecode (where they should match).
