Amazon Managed Blockchain (AMB) Query, which provides serverless access to multi-blockchain datasets, now delivers non-finalized blockchain transactions. This enables applications to quickly respond to the most recent events on the blockchain, including events from internal transactions.

Developers can now use AMB Query to build Web3 applications that need instant access to blockchain events once they are confirmed on the blockchain, even if the transactions are not finalized. For example, a wallet custody provider or gaming application developer can use the AMB Query ListTransactions API to learn about non-finalized transactions, and then invoke the AMB Query ListTransactionEvents API to notify their users of incoming funds or tokens as soon as the transactions are confirmed on the blockchain.

AMB Query is generally available in the US East (N. Virginia) region, making it easier than ever to access blockchain data such as historical balances and transactions with sub-second latency without the need for specialized infrastructure. Customers of AMB Query get blockchain data from the most popular networks delivered at scale and speed to meet the performance needs of real-world applications. Customers pay only for the API calls made with simple and predictable pricing. To learn more about AMB Query, see the user documentation.
