Usage

All necessary documentation of usage is provided via test files.

Using in browser

You will need webpack/browserify to bundle this library and it's dependencies to be able to use it in browser environment. Since tiny-secp256k1 is a WASM library, it will require such bundler to be able to load WASM code. Please consult the docs of a bundler that you use for further information.

For example current webpack will require you to set { experiments: { asyncWebAssembly: true }} in your config.

Mainnet

import {PaymentCode} from '@samouraiwallet/bip47';

const b58PCode = 'PM8TJS2JxQ5ztXUpBBRnpTbcUXbUHy2T1abfrb3KkAAtMEGNbey4oumH7Hc578WgQJhPjBxteQ5GHHToTYHE3A1w6p7tU6KSoFmWBVbFGjKPisZDbP97';

const pcode = PaymentCode.fromBase58(b58PCode);
const notifAddr = pcode.getNotificationAddress();

const myPrivKey0 = Buffer.from('8d6a8ecd8ee5e0042ad0cb56e3a971c760b5145c3917a8e7beaf0ed92d7a520c', 'hex');
const paymentAddr1 = pcode.getPaymentAddress(myPrivKey0, 1);
const paymentAddr2 = pcode.getPaymentAddress(myPrivKey0, 2);
