Validating Deposits

This section describes how to listen to incoming transactions and decrypting notes.

Transaction Streams #

If your account is receiving transactions, you can use the Transaction Stream API (see here).

async function main(): Promise<void> {
  const config = JSON.parse((await fsAsync.readFile('.ironfish.config.json')).toString());
  const sdk = await IronfishSdk.init(config);
  const client = await sdk.connectRpc();

  const account = '<account incoming view key>';
  const confirmations = <confirmations>;
  const head = <head sequence>;

  const options = {
    account,
    confirmations,
    head,
  };

  const response = await client.wallet.getAccountTransactionsStream(options);
  for await (const content of response.contentStream()) {
    console.log(content);
  }
}

It's recommended to configure confirmations to be greater than 0 if you'd like confidence that a block has been confirmed with low probability of a reorganization. The default value used in Iron Fish is 2, but you can increase this value for higher confidence.
