Local Development (Anvil)

requires foundry

forge install
forge test

Because v4 exceeds the bytecode limit of Ethereum and it's business licensed, we can only deploy & test hooks on anvil.

# start anvil, with a larger code limit
anvil --code-size-limit 30000

# in a new terminal
forge script script/Counter.s.sol \
    --rpc-url http://localhost:8545 \
    --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 \
    --code-size-limit 30000 \
    --broadcast
