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.
