Development

Local Development

Start a local node

You can start a local node with the following command. The node will provide a JSON-RPC endpoint at http://localhost:8545 and test accounts.

anvil

Edit .env file to set PRIVATE_KEY from the given test account and reload .env file.

source .env

Deploy to local node

First, install the dependencies:

forge install

Then execute the script to deploy to the local node:

forge script script/Deploy.s.sol:DeployLocal --broadcast --rpc-url ${LOCAL_RPC_URL}

Debugging

For example, you can call accountImplementation() function to get the address of the account implementation address. Replace YOUR_DEPLOYED_FACTORY_CONTRACT_ADDRESS with the address of the deployed contract. For more information, please refer to Cast.

cast call YOUR_DEPLOYED_FACTORY_CONTRACT_ADDRESS "accountImplementation()(address)" --rpc-url ${LOCAL_RPC_URL}

Compile

forge build --sizes

Test

forge test

with printing execution traces for failing tests

forge test -vvv

with gas reporting

forge test --gas-report

Deployment
