Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

Usage

Setup .env file with the following:

ETHERSCAN_API_KEY="TBD"
ARBISCAN_API_KEY="TBD"
BASESCAN_API_KEY="TBD"
OPTISCAN_API_KEY="TBD"
POLYSCAN_API_KEY="TBD"

Setup Deployer Wallet

Should use deploykey.cb.id private key and password:

cast wallet import deployer --interactive

Deploy

Deployed to 0x774E33F3271357E978440b9894a8a3bB3572933c on base. Don't forget to set the API key for verification!

forge script script/SubscriptionManager.s.sol:SubscriptionManagerScript --rpc-url ${DESIRED NETWORK} --account deployer --verify --broadcast

Verify

If you messed up on verifying the contract on deploy then you can do it with the following command:

forge verify-contract ${NEW CONTRACT ADDRESS} src/SubscriptionManager.sol:SubscriptionManager --rpc-url base --chain base --watch --guess-constructor-args
