Bitcoin-style dapps

Pali's UTXO provider makes browser dapps possible for Bitcoin-style account flows, including Syscoin UTXO and compatible transaction models.

What changes versus EVM

EVM dapps usually ask one account to sign a transaction object. UTXO dapps usually:

1. Read account and UTXO state.
2. Build a PSBT.
3. Include a change address.
4. Ask the wallet to sign.
5. Finalize and broadcast.

Minimum integration shape

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

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

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

Best practices

• Build PSBTs deterministically and show users a transaction summary in your app.
• Use Pali's change address instead of reusing receive addresses.
• Handle testnet/mainnet differences.
• Handle wallet lock, rejection, and network mismatch errors.
• Avoid requesting xpub or signing until the user initiates a meaningful action.
