Example Wallet Key Data

DashTx does not depend on any specific implementation of a wallet key storage engine, but it works great with plain-old JSON:

let yourWalletKeyMapGoesHere = {
  yTw3SFk9PbQ1kikMgJBRA7CFyLfNt2G6QD: {
    hdpath: "0bGYi3S7n2Q|m/44'/1'/0'/0/0",
    address: "yTw3SFk9PbQ1kikMgJBRA7CFyLfNt2G6QD",
    wif: "cUeUEgRQWfKiYPBeRZsYsrvvSZiKHbUNqiQE2AdKA4s7ymycdVxc",
  },
  yb4zn8MSW4hHsvmP6PxX2tUPDb9bvmxSrS: {
    hdpath: "0bGYi3S7n2Q|m/44'/1'/0'/0/1",
    wif: "cN28SZpmmuVFmmBQBHCNdwa6a14kWZM8VVpZETjzk47aGNvVGXK7",
    address: "yb4zn8MSW4hHsvmP6PxX2tUPDb9bvmxSrS",
  },
  yfrB4v4cih7os6t1tg4YuWkrTYmHyMHkZb: {
    hdpath: "0bGYi3S7n2Q|m/44'/1'/0'/0/2",
    address: "yfrB4v4cih7os6t1tg4YuWkrTYmHyMHkZb",
    wif: "cQBHjCxspabNZKGMK3gbuvSLgssqSxAuDsaMMDuzgXioYyR723Bg",
  },
  // ...
};

You can use any indexing, query, or storage strategy you like, with values in Base58Check, Hex, Byte, or whatever else you fancy - just as long as your provided Key Util functions can convert them.

Example Key Utils

DashTx does not depend on any specific implementation of signing or key transformation, but it works greeat NobleSecp256k1 and DashKeys:

getPrivateKey(txInput, i)
getPublicKey(txInput, i)
sign(privKeyBytes, txHashBytes)
toPublicKey(privKeyBytes)
let keyUtils = {
  getPrivateKey: async function (txInput, i) {
    let pkhBytes = DashKeys.utils.hexToBytes(txInput.pubKeyHash);
    let address = await DashKeys.pkhToAddr(txInput.pubKeyHash);

    let yourKeyData = yourWalletKeyMapGoesHere[address];

    let privKeyBytes = DashKeys.wifToPrivKey(yourKeyData.wif);
    return privKeyBytes;
  },

  getPublicKey: async function (txInput, i) {
    let privKeyBytes = getPrivateKey(txInput, i);
    let pubKeyBytes = await keyUtils.toPublicKey(privKeyBytes);

    return pubKeyBytes;
  },

  sign: async function (privKeyBytes, txHashBytes) {
    let sigOpts = { canonical: true, extraEntropy: true };
    let sigBytes = await Secp256k1.sign(txHashBytes, privKeyBytes, sigOpts);

    return sigBytes;
  },

  toPublicKey: async function (privKeyBytes) {
    let isCompressed = true;
    let pubKeyBytes = Secp256k1.getPublicKey(privKeyBytes, isCompressed);

    return pubKeyBytes;
  },
};

Example Tx Info

      // OP_RETURN messages are supported as HEX!

Example Coin Selection & Fee Calculation

// for backwards compatibily with JSON Payment Protocol, etc
Tx.createLegacyTx(coins, outputs, changeOutput)

// (coming soon... ?)
// for use with Contacts and Cash-Like send (uses XPubs & denominates coins)
Tx.createTx(coins, outputs, { allowChange: true, breakChange: true })

Given an array of coins (UTXOs), DashTx can do the hard work of correctly selecting a minimal set of inputs that cover the output costs and fees, and insert a change output if necessary.

let coins = [
  {
    satoshis: 1_000_00000,
    txid: "7f305558cbeba3a9271d2559e8277f473f29d6b64a7a7a27e02a8564bde8352b",
    outputIndex: 0,
    // you may have one or more address identifiers
    publicKey:
      "03755be68d084e7ead4d83e23fb37c3076b16ead432de1b0bdf249290400f263cb",

  },
  {
    satoshis: 2_500_00000,
    // ...
  },
  {
    satoshis: 1_500_00000,
    // ...
  },
];

let outputs = [
  {
    satoshis: 1_200_00000,
    // ...
  },
];

let changeOutput = {
  pubKeyHash: "5bcd0d776a7252310b9f1a7eee1a749d42126944",
};

let txInfo = await Tx.createLegacyTx(coins, outputs, changeOutput);
