Polling

---

If your transaction is successfully verified by the seed node, the transaction will be sent to the appropriate shard. Shard selection depends on a number of factors that are explained in detail in this post.

After sending the transaction object, there will be a transaction id. We can invoke the GetTransaction JSON RPC API with the transaction id periodically to check the transaction status. It is recommended to poll the seed node with GetTransaction for 3 Tx Epochs (around 3-5 minutes). If the transaction is not confirmed after that, we can assume that it has not been included in any block and should be re-broadcasted.

Example of transaction polling:

• JavaScript
• Go
• Java

const txn = await zilliqa.blockchain.getTransaction(

'1899b381d644a4892ca5ba5d8d60bbcc7bd121d511d55e438a8ddbdcc53272c4'

);

console.log(JSON.stringify(txn));
