PSBT and transactions

UTXO applications should construct transactions carefully, request a signature through Pali, and broadcast only after the user approves.

Pali PSBT signing review screen
Pali prompts the user before signing UTXO PSBTs.
const signed = await window.pali.request({
  method: 'sys_sign',
  params: [psbtBase64],
});

Sign and send​

const txid = await window.pali.request({
  method: 'sys_signAndSend',
  params: [psbtBase64],
});

Fetch transactions​

const transactions = await window.pali.request({
  method: 'sys_getTransactions',
});

const tx = await window.pali.request({
  method: 'sys_transaction',
  params: [txid],
});

Validate an address​

const valid = await window.pali.request({
  method: 'sys_isValidSYSAddress',
  params: [address],
});

Dapp responsibility​

Pali signs what the user approves. Your application is responsible for constructing sane PSBT inputs, outputs, fees, change, and asset metadata before requesting a signature.
