Setup

Tip

We suggest you set up local anvil account with cast.

cast wallet import --mnemonic "test test test test test test test test test test test junk" anvil

• This will allow you to use --account anvil in the deploys scripts in .dev/start_script.sh

Run local anvil node with Unichain fork

anvil --fork-url https://unichain.drpc.org
# or simulate block mining and finality
anvil --block-time 13

Local Deployment

Run deployment script

./dev/start_script.sh # scripts that you use --account setup of you choice

Note

The start scripts will do the following:

1. Deploy local PoolManger ./script/00_DeployPoolManager.s.sol
2. Deploy Hook & Router contracts ./script/01_DeployHook.s.sol
3. Initialize a pool with your hook attached ./script/02_InitilizePool.s.sol
4. Add liqudity to previously initialized pool ./script/03_AddLiquidity.s.sol
5. Submit an async swap transaction through custom router ./script/04_Swap.s.sol
6. Fill previously submitted swap transaction ./script/05_ExecuteOrder.s.sol

Testing

Run tests

forge test -vvvv

Huff tests:

# sender is poolManager address
hnc src/AsyncSwap.huff test --sender 0x0000000000000000000000000000000000000000

Offchain Indexer

Start local indexer
