tap-protocol-helper v0.1.4

TAP Protocol helper library

Helper functions for signing TAP Protocol inscriptions.

Description

This package provides a set of helper scripts designed to facilitate the creation of signed authority inscriptions for the TAP Protocol. It includes functionality for signing privilege authority messages, token authority, and token redemption using various cryptographic protocols.

The library has been implemented using references from TAP Protocol specs and TAP Protocol authority boiler plate

Installation

To install the package, run the following command:

yarn add tap-protocol-helper

or

npm install tap-protocol-helper

Usage

To use the Tap Helper functions, you can import the Tap and Utils modules into your project as follows:

const { Tap, Utils } = require("tap-protocol-helper");
const { ECPair } = require("tap-protocol-helper/dist/core");

Optionals:

const { bitcoin, ecc } = require("tap-protocol-helper/dist/core");
const { toXOnly } = require("bitcoinjs-lib/src/psbt/bip371");

1. Signing a privilege-auth inscription

Use the signAuth function to sign a privilege-auth message:

const keypair = ECPair.makeRandom(); // Replace with your keypair generation method
const msgKey = "auth";
const message = { name: "tap-protocol-privilege-auth-000" };
const salt = Math.random(); // Optional: Provide your own salt value

const priv_auth = Tap.signAuth(keypair.privateKey, keypair.publicKey, msgKey, message, salt);

Example output:

{
    test: {
        valid: true,
        pub: "0282984730b88570f86c56d475d90258d1ca9755373e18fabc130791923f9e0f4a",
        pubRecovered: "0282984730b88570f86c56d475d90258d1ca9755373e18fabc130791923f9e0f4a"
    },
    result: '{"p":"tap","op":"privilege-auth","sig":{"v":"0","r":"16305713734998215074335603060711813150048114674529647022075032070990566113517","s":"40018336075309720814901490213864323243237297900828141635735508366496148314591"},"hash":"8fa604b40f239c27995d58c773eb846c9122cc77541d1a0ac770ba4a52f4abcc","salt":"0.4840164898423085","auth":{"name":"tap-protocol-privilege-auth-000"}}'
}

The result field in the output above is the signed inscription text to be inscribed:

{
    "p": "tap",
    "op": "privilege-auth",
    "sig": {
        "v": "0",
        "r": "16305713734998215074335603060711813150048114674529647022075032070990566113517",
        "s": "40018336075309720814901490213864323243237297900828141635735508366496148314591"
    },
    "hash": "8fa604b40f239c27995d58c773eb846c9122cc77541d1a0ac770ba4a52f4abcc",
    "salt": "0.4840164898423085",
    "auth": { "name": "tap-protocol-privilege-auth-000" }
}

2. Signing a token-mint inscription

Use signMint to create a token-mint inscription text

const keypair = ECPair.makeRandom(); // Replace with your keypair generation method
const ticker = "tap-token-auth";
const amount = 1000;
const salt = Math.random(); // Optional: Provide your own salt value
const minter = 'tb1p96fnzkff6af94z0zpaahqws45rjcw5fd6wk3pe2w7cqz279wl6rqzw0k37'

const mint_auth = signMint(keypair.privateKey, keypair.publicKey, ticker, amount, minter, salt);

Example output:

{
    test: {
        valid: true,
        pub: "02801d73a46adffac2a0bc9bddce670a64b99e97df87a1c86aa38dab8f642cdcdd",
        pubRecovered: "02801d73a46adffac2a0bc9bddce670a64b99e97df87a1c86aa38dab8f642cdcdd"
    },
    result: '{"p":"tap","op":"token-mint","tick":"tap-token-auth","amt":1000,"prv":{"sig":{"v":"0","r":"28840735240323581642649166158114847033326200650757009309461520982937724983138","s":"43031653986158326967040449621257596604714194318555432467794807862498111678116"},"hash":"b117c449ebba4b9f033ad46daa55a1004369463cdc757bd98a27ac05317e7165","address":"tb1p96fnzkff6af94z0zpaahqws45rjcw5fd6wk3pe2w7cqz279wl6rqzw0k37","salt":"0.4840164898423085"}}'
}

The inscription text to be inscribed:

{
    "p": "tap",
    "op": "token-mint",
    "tick": "tap-token-auth",
    "amt": 1000,
    "prv": {
        "sig": {
            "v": "0",
            "r": "28840735240323581642649166158114847033326200650757009309461520982937724983138",
