};

let valid = await wallet.validAddress(p);

Transfer

import { KaspaWallet } from "@okxweb3/coin-kaspa";

let wallet = new KaspaWallet();

let p: SignTxParams = {

    data: {

        inputs: [

            {

                txId: "ec62c785badb0ee693435841d35bd05da9c8a40aa2d568dddb0dd47410e7e78a",

};

let tx = await wallet.signTransaction(p);

Calculate txId

import { KaspaWallet } from "@okxweb3/coin-kaspa";

let wallet = new KaspaWallet();

let p: CalcTxHashParams = {

    data: {"transaction":{"version":0,"inputs":[{"previousOutpoint":{"transactionId":"ec62c785badb0ee693435841d35bd05da9c8a40aa2d568dddb0dd47410e7e78a","index":1},"signatureScript":"411687d956de8e3cc53b9dbf20ede3922b422595abbad31ecf38ff90c0cf8ef7c3b5ae71628e041a3a0f1b9ad6e14bb6d49dd7c35f06c46316b67c10d477c29ac001","sequence":0,"sigOpCount":1}],"outputs":[{"scriptPublicKey":{"version":0,"scriptPublicKey":"200395c7c9703e0ff81596043f0a5e00684f860a1ab0f24c5a94931d1e0d94c4beac"},"amount":587700}],"lockTime":0,"subnetworkId":"0000000000000000000000000000000000000000"},"allowOrphan":false},

};

let txId = await wallet.calcTxHash(p);

Sign message

import { KaspaWallet } from "@okxweb3/coin-kaspa";

let wallet = new KaspaWallet();

let p: SignTxParams = {

    data: {

        message: "Hello Kaspa!",

    },

    privateKey: "d636a23d4f49fe4e0d59fcf7a6c2ab3846ff2d3a54007b3817a11dff770d06ff",

};

let sig = await wallet.signMessage(p);
