cast wallet sign

Sign a message or typed data

$ cast wallet sign --help
Usage: cast wallet sign [OPTIONS] <MESSAGE> Arguments: <MESSAGE> The message, typed data, or hash to sign. Messages starting with 0x are expected to be hex encoded, which get decoded before being signed. The message will be prefixed with the Ethereum Signed Message header and hashed before signing, unless `--no-hash` is provided. Typed data can be provided as a json string or a file name. Use --data flag to denote the message is a string of typed data. Use --data --from-file to denote the message is a file name containing typed data. The data will be combined and hashed using the EIP712 specification before signing. The data should be formatted as JSON. Options: --data Treat the message as JSON typed data --from-file Treat the message as a file containing JSON typed data. Requires `--data` --no-hash Treat the message as a raw 32-byte hash and sign it directly without hashing it again -h, --help Print help (see a summary with '-h') -j, --threads <THREADS> Number of threads to use. Specifying 0 defaults to the number of logical cores [aliases: jobs] Wallet options - raw: -f, --from <ADDRESS> The sender account [env: ETH_FROM=] -i, --interactive Open an interactive prompt to enter your private key --private-key <RAW_PRIVATE_KEY> Use the provided private key --mnemonic <MNEMONIC> Use the mnemonic phrase of mnemonic file at the specified path --mnemonic-passphrase <PASSPHRASE> Use a BIP39 passphrase for the mnemonic --mnemonic-derivation-path <PATH> The wallet derivation path. Works with both --mnemonic-path and hardware wallets. --mnemonic-index <INDEX> Use the private key from the given mnemonic index. Used with --mnemonic-path. [default: 0] Wallet options - keystore: --keystore <PATH> Use the keystore in the given folder or file [env: ETH_KEYSTORE=] --account <ACCOUNT_NAME> Use a keystore from the default keystores folder (~/.foundry/keystores) by its filename [env: ETH_KEYSTORE_ACCOUNT=] --password <PASSWORD> The keystore password. Used with --keystore. --password-file <PASSWORD_FILE> The keystore password file path. Used with --keystore. [env: ETH_PASSWORD=] Wallet options - hardware wallet: -l, --ledger Use a Ledger hardware wallet -t, --trezor Use a Trezor hardware wallet Wallet options - remote: --aws Use AWS Key Management Service Display options: --color <COLOR> The color of the log messages Possible values: - auto: Intelligently guess whether to use color output (default) - always: Force color output - never: Force disable color output --json Format log messages as JSON -q, --quiet Do not print log messages -v, --verbosity... Verbosity level of the log messages. Pass multiple times to increase the verbosity (e.g. -v, -vv, -vvv). Depending on the context the verbosity levels have different meanings. For example, the verbosity levels of the EVM are: - 2 (-vv): Print logs for all tests. - 3 (-vvv): Print execution traces for failing tests. - 4 (-vvvv): Print execution traces for all tests, and setup traces for failing tests. - 5 (-vvvvv): Print execution and setup traces for all tests, including storage changes.
