building a address-query-scanner for work

Post original

If you just need a ping when an address makes a transaction, you can watch each new block and check which address made each transaction in it. The hard parts come later. If your script stops and starts again, it should continue from where it left off instead of skipping what it missed. Sometimes the network reverses a recent block, so an alert you already sent turns out wrong. And if one alert fails to send, you don't want to lose it. Honestly for a one-off work tool I'd just write the script and not over-engineer it. We ended up building a thing (Atria) that handles those edge cases for you, only worth it if this needs to run reliably long-term. If you want to see the shape of it, the quick start: https://docs.pulsy.app/atria/getting-started/overview
