# und tx multi-sign
Generate multisig signatures for transactions generated offline
# Synopsis
Sign transactions created with the --generate-only flag that require multisig signatures.
Read one or more signatures from one or more [signature] file, generate a multisig signature compliant to the multisig key [name], and attach the key name to the transaction read from [file].
Example: $ und tx multisign transaction.json k1k2k3 k1sig.json k2sig.json k3sig.json
If --signature-only flag is on, output a JSON representation of only the generated signature.
If the --offline flag is on, the client will not reach out to an external node. Account number or sequence number lookups are not performed so you must set these parameters manually.
If the --skip-signature-verification flag is on, the command will not verify the signatures in the provided signature files. This is useful when the multisig account is a signer in a nested multisig scenario.
The current multisig implementation defaults to amino-json sign mode. The SIGN_MODE_DIRECT sign mode is not supported.'
und tx multi-sign [file] [name] [[signature]...] [flags]
# Options
-a, --account-number uint The account number of the signing account (offline mode only)
--aux Generate aux signer data instead of sending a tx
-b, --broadcast-mode string Transaction broadcasting mode (sync|async) (default "sync")
--chain-id string The network chain ID
--dry-run ignore the --gas flag and perform a simulation of a transaction, but don't broadcast it (when enabled, the local Keybase is not accessible)
--fee-granter string Fee granter grants fees for the transaction
--fee-payer string Fee payer pays fees for the transaction instead of deducting from the signer
--fees string Fees to pay along with transaction; eg: 10uatom
--from string Name or address of private key with which to sign
--gas string gas limit to set per-transaction; set to "auto" to calculate sufficient gas automatically. Note: "auto" option doesn't always report accurate results. Set a valid coin value to adjust the result. Can be used instead of "fees". (default 200000)
--gas-adjustment float adjustment factor to be multiplied against the estimate returned by the tx simulation; if the gas limit is set manually this flag is ignored (default 1)
--gas-prices string Gas prices in decimal format to determine the transaction fee (e.g. 0.1uatom)
--generate-only Build an unsigned transaction and write it to STDOUT (when enabled, the local Keybase only accessed when providing a key name)
-h, --help help for multi-sign
--keyring-backend string Select keyring's backend (os|file|kwallet|pass|test|memory) (default "os")
--keyring-dir string The client Keyring directory; if omitted, the default 'home' directory will be used
--ledger Use a connected Ledger device
--node string <host>:<port> to CometBFT rpc interface for this chain (default "tcp://localhost:26657")
--note string Note to add a description to the transaction (previously --memo)
--offline Offline mode (does not allow any online functionality)
--output-document string The document is written to the given file instead of STDOUT
-s, --sequence uint The sequence number of the signing account (offline mode only)
--sign-mode string Choose sign mode (direct|amino-json|direct-aux|textual), this is an advanced feature
--signature-only Print only the generated signature, then exit
--skip-signature-verification Skip signature verification
--timeout-height uint Set a block timeout height to prevent the tx from being committed past a certain height
--tip string Tip is the amount that is going to be transferred to the fee payer on the target chain. This flag is only valid when used with --aux, and is ignored if the target chain didn't enable the TipDecorator
-y, --yes Skip tx broadcasting prompt confirmation
