Usage

Server (acts as the co-signer in the two-party signing protocol):

import { Ed25519Party1 } from '@kzen-networks/tezos-thresh-wallet';

new Ed25519Party1().launchServer();

Client:

import TezClient, { Ed25519Party2, Ed25519Party2Share } from '@kzen-networks/tezos-thresh-wallet';
const client = new TezClient('http://127.0.0.1:8732');

const P1_SERVER_ENDPOINT = 'http://localhost:8000';
const party2 = new Ed25519Party2(P1_SERVER_ENDPOINT);

(async () => {
  await client.importEd25519Party2(party2);  // activates two-party key generation protocol
  const address = client.party2.publicKeyHash();
  console.log(address);
  // tz1csGALMvB6sh3KJyHAMYVYVMUaucBgBDw7

  /* Now you should deposit XTZ into this address */

  console.log(await client.getBalance(address));  // in mutez (1 XTZ = 1,000,000 mutez)
  // 982974

  const { hash } = await client.transfer({
    source: address,
    to: 'tz1YaqLFe8nywjCiAF1vK1U1yns69nPQoyg1',
    amount: 10000
  });
  console.log(hash);
