Nunchuk Wallet Transactions

If auth or network setup is the blocker, use nunchuk-setup.

Default workflow

Progress:

• Create the transaction
• Sign the transaction
• Broadcast the transaction

If the user explicitly asks for only sign, only broadcast, or only inspect, do only that step.

Create

Create a transaction:

nunchuk tx create --wallet <wallet-id> --to <address> --amount <satoshis>

Sign

Sign with all matching stored keys:

nunchuk tx sign --wallet <wallet-id> --tx-id <tx-id>

Sign with a specific stored key:

nunchuk tx sign --wallet <wallet-id> --tx-id <tx-id> --fingerprint <xfp>

Merge an externally signed PSBT:

nunchuk tx sign --wallet <wallet-id> --tx-id <tx-id> --psbt <signed-psbt-base64>

Inspect

List transactions:

nunchuk tx list --wallet <wallet-id>

Get one transaction:

nunchuk tx get --wallet <wallet-id> --tx-id <tx-id>

Broadcast

Broadcast a fully signed transaction:

nunchuk tx broadcast --wallet <wallet-id> --tx-id <tx-id>

Common requests

User asks: send 100 USD to an address:

nunchuk tx create --wallet <wallet-id> --to <address> --amount 100 --currency USD

User asks: send 250 USD to an address, then sign and broadcast:

nunchuk tx create --wallet <wallet-id> --to <address> --amount 250 --currency USD
nunchuk tx sign --wallet <wallet-id> --tx-id <tx-id>
nunchuk tx broadcast --wallet <wallet-id> --tx-id <tx-id>

User asks: sign with a hardware wallet or external signer:

# Get the current pending PSBT.
nunchuk tx get --wallet <wallet-id> --tx-id <tx-id> --json

# Sign that PSBT externally, then merge it back.
nunchuk tx sign --wallet <wallet-id> --tx-id <tx-id> --psbt <signed-psbt-base64>

Defaults

• tx create treats --amount as satoshis by default.
• Use --currency for fiat or BTC amounts.
• tx create estimates the fee rate automatically.
• If no key option is provided, tx sign auto-detects matching stored keys for the wallet and signs with all of them.
• Use tx get --json to retrieve the current pending PSBT before signing externally.
• Use --json when the user needs exact machine-readable output.

Gotchas

• tx sign skips keys that already signed the PSBT.
• tx sign --psbt cannot be used with --xprv or --fingerprint.
• tx broadcast requires a fully signed transaction, status is READY_TO_BROADCAST.
