Test

$ forge test

Format

$ forge fmt

Gas Snapshots

Anvil

$ anvil

Deploy

$ forge script script/Message.s.sol:MessageScript --rpc-url <your_rpc_url> --private-key <your_private_key>

Cast

Working with a local network

Foundry comes with local network anvil baked in, and allows us to deploy to our local network for quick testing locally.

To start a local network run:

make anvil

This will spin up a local blockchain with a determined private key, so you can use the same private key each time.

Then, you can deploy to it with:

make deploy-anvil contract=<CONTRACT_NAME>

Similar to deploy-sepolia or deploy-mumbai

Working with other chains

To add a chain, you'd just need to make a new entry in the Makefile, and replace <YOUR_CHAIN> with whatever your chain's information is.

deploy-<YOUR_CHAIN> :; @forge script script/${contract}.s.sol --rpc-url ${<YOUR_CHAIN>_RPC_URL}  --private-key ${PRIVATE_KEY} --broadcast -vvvv
