forge script

Run a smart contract as a script, building transactions that can be sent onchain

$ forge script --help

Usage: forge script [OPTIONS] <PATH> [ARGS]...

Arguments:
  <PATH>
          The contract you want to run. Either the file path or contract name.
          
          If multiple contracts exist in the same file you must specify the
          target contract with --target-contract.

  [ARGS]...
          Arguments to pass to the script function

Options:
      --target-contract <CONTRACT_NAME>
          The name of the contract you want to run
          
          [aliases: tc]

  -s, --sig <SIG>
          The signature of the function you want to call in the contract, or raw
          calldata
          
          [default: run()]

      --priority-gas-price <PRICE>
          Max priority fee per gas for EIP1559 transactions
          
          [env: ETH_PRIORITY_GAS_PRICE=]

      --legacy
          Use legacy transactions instead of EIP1559 ones.
          
          This is auto-enabled for common networks without EIP1559.

      --broadcast
          Broadcasts the transactions

      --batch-size <BATCH_SIZE>
          Batch size of transactions.
          
          This is ignored and set to 1 if batching is not available or `--slow`
          is enabled.
          
          [default: 100]

      --skip-simulation
          Skips on-chain simulation

  -g, --gas-estimate-multiplier <GAS_ESTIMATE_MULTIPLIER>
          Relative percentage to multiply gas estimates by
          
          [default: 130]

      --unlocked
          Send via `eth_sendTransaction` using the `--from` argument or
          `$ETH_FROM` as sender

      --resume
          Resumes submitting transactions that failed or timed-out previously.
          
          It DOES NOT simulate the script again and it expects nonces to have
          remained the same.
          
          Example: If transaction N has a nonce of 22, then the account should
          have a nonce of 22, otherwise it fails.

      --multi
          If present, --resume or --verify will be assumed to be a multi chain
          deployment

      --debug
          Open the script in the debugger.
          
          Takes precedence over broadcast.

      --slow
          Makes sure a transaction is sent, only after its previous one has been
          confirmed and succeeded

      --non-interactive
          Disables interactive prompts that might appear when deploying big
          contracts.

          Output results in JSON format

      --with-gas-price <PRICE>
          Gas price for legacy transactions, or max fee per gas for EIP1559
          transactions, either specified in wei, or as a string with a unit
          type.
          
          Examples: 1ether, 10gwei, 0.01ether
          
          [env: ETH_GAS_PRICE=]
