  -m, --mnemonic <MNEMONIC>

      --mnemonic-random [<MNEMONIC_RANDOM>]
          Automatically generates a BIP39 mnemonic phrase, and derives accounts from it. Cannot be used with other `mnemonic` options You can specify the number of words you want in the mnemonic. [default: 12]

      --mnemonic-seed-unsafe <MNEMONIC_SEED>
          Generates a BIP39 mnemonic phrase from a given seed Cannot be used with other `mnemonic` options
          CAREFUL: this is NOT SAFE and should only be used for testing. Never use the private keys generated in production.

          [aliases: no-mine]

      --order <ORDER>

  -s, --state-interval <SECONDS>
          Interval in seconds at which the state and block environment is to be dumped to disk.
          See --state and --dump-state

          Don't print anything on startup and don't print logs

      --state <PATH>
          This is an alias for both --load-state and --dump-state.
          It initializes the chain with the state and block environment stored at the file, if it exists, and dumps the chain's state on exit.

      --timestamp <NUM>
          The timestamp of the genesis block

      --transaction-block-keeper <TRANSACTION_BLOCK_KEEPER>
          Number of blocks with transactions to keep in memory

  -V, --version
          Print version

Server options:
      --allow-origin <ALLOW_ORIGIN>
          Set the CORS allow_origin
          [default: *]

      --host <IP_ADDR>
          The hosts the server will listen on
          [env: ANVIL_IP_ADDR=]

          Disable CORS

Fork config:
      --compute-units-per-second <CUPS>
          Sets the number of assumed available compute units per second for this provider
          default value: 330
          See --fork-url. See also,

  -f, --fork-url <URL>
          Fetch state over a remote endpoint instead of starting from an empty state.
          If you want to fetch state from a specific block number, add a block number like `http://localhost:8545@1400000` or use the `--fork-block-number` argument.
          [aliases: rpc-url]

      --fork-block-number <BLOCK>
          Fetch state from a specific block number over a remote endpoint.
          See --fork-url.

      --fork-chain-id <CHAIN>
          Specify chain id to skip fetching it from remote endpoint. This enables offline-start mode.
          You still must pass both `--fork-url` and `--fork-block-number`, and already have your required state cached on disk, anything missing locally would be fetched from the remote.

      --fork-header <HEADERS>
          Headers to use for the rpc client, e.g. "User-Agent: test-agent"
          See --fork-url.

      --fork-retry-backoff <BACKOFF>
          Initial retry backoff on encountering errors.
          See --fork-url.

          Disables rate limiting for this node's provider.
          default value: false
          See --fork-url. See also,
          [aliases: no-rpc-rate-limit]

          Explicitly disables the use of RPC caching.
          All storage slots are read entirely from the endpoint.
          This flag overrides the project's configuration file.
          See --fork-url.

      --retries <retries>
          Number of retry requests for spurious networks (timed out requests)
          Default value 5

      --timeout <timeout>
          Timeout in ms for requests sent to remote JSON-RPC server in forking mode.
          Default value 45000

Environment config:
      --block-base-fee-per-gas <FEE>
          The base fee in a block
          [aliases: base-fee]

      --chain-id <CHAIN_ID>
          The chain ID

      --code-size-limit <CODE_SIZE>
          EIP-170: Contract code size limit in bytes. Useful to increase this because of tests. By default, it is 0x6000 (~25kb)

          Disable the `call.gas_limit <= block.gas_limit` constraint

      --gas-limit <GAS_LIMIT>
          The block gas limit

      --gas-price <GAS_PRICE>
          The gas price
