Who can guide me I how to monitor transactions. I’m building a Wallet app, I want to send notification to wallet user devices when they received a transaction from other. I didn’t find any post about it.
Please help me.
Thank you so much.

Hi, you have two choices:
- period request… see the source code of AWallet payment gateway … Example
- create your own indexer with websocket feeds… eg this one feeds graphql and using subscription you can get the notifications right away on new block. See VoteCoin indexer
@thangbk Btw if your goal is to create new wallet, perhaps you might clone/cooperate on AWallet… the first open source community algorand PWA wallet, currently supports multisig, rekeying, payment gateway, making account online …
