Quick start

import Signer from "@meowcoin-foundation/meowcoin-sign-transaction";

const network = "mewc"; // or "mewc-test"

const rawUnsignedTransaction =
  "02000000010d5fc31678777ee0c338379325df8cd0bc75249a607c408de6c012fa007c50ae0100000000ffffffff0200e40b54020000001976a9141239cd8e03d180a55b75763f9ef7424b7e2eee8f88acc0958bc42e0800001976a9147ba628b84127e132b1352022b2bb58eaeaed340888ac00000000";

const UTXOs = [
  {
    address: "mgRYHdMqD1gwm9QQqBRUPcDKdEZ9oVeChA",
    assetName: "MEWC",
    txid: "ae507c00fa12c0e68d407c609a2475bcd08cdf25933738c3e07e777816c35f0d",
    outputIndex: 1,
    script: "76a91409f2017224efdaf3633d26b1cf11a1df418496f688ac",
    satoshis: 9006961000000,

const signed = Signer.sign(network, rawUnsignedTransaction, UTXOs, privateKeys);

console.log(signed); // hex string ready to broadcast

API

Signer.sign(network, rawTxHex, utxos, privateKeys)

• network: "mewc" | "mewc-test" | "evr" | "evr-test"
• rawTxHex: string – unsigned transaction hex
• utxos: array of objects containing address, txid, outputIndex, script, and satoshis
• privateKeys: object keyed by address with WIF strings for the selected network

Returns the signed transaction hex. Broadcasting is up to you (RPC, electrum, etc.).
