Tysm @jrcarlos2000 🙌 !!

"fork": "anvil --fork-url ${0:-mainnet} --chain-id 31337 --config-out localhost.json",

Curious about what ${0:-mainnet} do ?

Also, I was wondering if there a direct way to setup to this defult in foundry.toml file ?

Like even if we people manually do anvil --fork-url URL_WITH_API_KEY it will default to chainId 31337 because of default in foundry.toml 🤔 ?

${0:-mainnet} will take the name of the network you declare in foundry.toml and use it for the fork. you can also pass an RPC_URL directly.

anvil wiill override the value of the chain id specified in toml to the chain id of the RPC specified for the fork. for now the only way of using 31337 would be pass --chain-id @technophile-04
