Symbol URI Scheme
URI Scheme library to serve Symbol transactions ready to be signed.
This is a PoC to validate the proposed NIP2 Transaction URI Scheme. When stable, the repository will be moved to the nemtech organization.
Requirements
- Node.js 12 LTS
Installation
npm install symbol-uri-scheme
Usage
Generate URI from Transaction
// examples/TransactionToURI.ts
import { Account, Deadline, EmptyMessage, Currency, NetworkType, TransferTransaction, TransactionMapping } from 'symbol-sdk';
import { TransactionURI } from '../src/uris/TransactionURI';
const epochAdjustment = 1637848847;
const serializedTransaction = TransferTransaction.create(
Deadline.create(epochAdjustment),
Account.generateNewAccount(NetworkType.TEST_NET).address,
[Currency.PUBLIC.createRelative(10)],
EmptyMessage,
NetworkType.TEST_NET
).serialize();
const generationHash = 'ABC'; // replace with network generation hash
const nodeUrl = 'http://localhost:3000';
const webhookUrl = 'http://myapp.local/id';
const transactionURI = new TransactionURI(serializedTransaction, TransactionMapping.createFromPayload, generationHash, nodeUrl, webhookUrl);
console.log(transactionURI.build());
Create Transaction from URI
// examples/URIToTransaction.ts
import { TransactionMapping } from 'symbol-sdk';
import { TransactionURI } from '../src/uris/TransactionURI';
const serializedTransaction = 'B600000000000000000000000000000000000000000' +
'0000000000000000000000000000000000000000000000000000000000000000000000000' +
'0000000000000000000000000000000000000000000000000000000000000000000000000' +
'0000000000000000000000000000190544100000000000000005816E98404000000900FFE' +

'C80969800000000000068656C6C6F';
const URI = 'web+symbol://transaction?data=' + serializedTransaction + '&generationHash=test' +
'&nodeUrl=http://localhost:3000&webhookUrl=http://myapp.local/id';
const transactionURI = TransactionURI.fromURI(URI, TransactionMapping.createFromPayload);
const transaction = transactionURI.toTransaction();
console.log(transaction);
