UniSat Wallet

UniSat Wallet API

Welcome to UniSat's Developer Documentation. This documentation is for learning to develop applications for UniSat Wallet.

Getting Started

To develop for UniSat Wallet, install UniSat Wallet on your development machine. Download here.

Once UniSat Wallet is installed and running, you should find that new browser tabs have a window.unisat object available in the developer console. This is how your website will interact with UniSat Wallet.

Browser Detection

To verify if the browser is running UniSat Wallet, copy and paste the code snippet below in the developer console of your web browser:

if (typeof window.unisat !== 'undefined') {
  console.log('UniSat Wallet is installed!');
}

You can review the full API for the window.unisat object here.

Connecting to UniSat Wallet

"Connecting" or "logging in" to UniSat Wallet effectively means "to access the user's Bitcoin account(s)".

You should only initiate a connection request in response to direct user action, such as clicking a button. You should always disable the "connect" button while the connection request is pending. You should never initiate a connection request on page load.

We recommend that you provide a button to allow the user to connect UniSat Wallet to your dapp. Clicking this button should call the following method:

unisat.requestAccounts()

signPsbt

unisat.signPsbt(psbtHex[, options])

Sign PSBT

This method will traverse all inputs that match the current address to sign.

Parameters

  • psbtHex - string: the hex string of psbt to sign

  • options

    • autoFinalized - boolean: whether finalize psbt after signing, default is true

    • toSignInputs - array:

      • index - number: which input to sign

      • address - string: (at least specify either an address or a publicKey) Which corresponding private key to use for signing

      • publicKey - string: (at least specify either an address or a publicKey) Which corresponding private key to use for signing

      • sighashTypes - number[]: (optionals) sighashTypes

      • disableTweakSigner - boolean :(optionals) Default value is false. Setting it true allows the use of the original private key when signing taproot inputs.

      • useTweakedSigner - boolean :(optionals) . By setting useTweakedSigner, you can forcibly decide whether or not to use tweakedSigner. It has a higher priority than disableTweakSigner.

Returns

  • Promise - string: the hex string of signed psbt

Example

try {
  let res = await window.unisat.signPsbt(
    "70736274ff01007d....",
