Ever needed to receive webhooks for blockchain events on EVM chains? We did! Existing commercial solutions can be too expensive for an early-stage startup. Also, what if you want full control of what's happening? We encountered this task in Yoki Finance and developed this open-source library to help you with webhooks – welcome Yoki-web3hooks!
api- API written with Nest.js to add webhook listeners.yoki-event-worker- worker that listens to blockchain events and puts webhooks into the queue (written in Golang)yoki-webhook-executor- worker that delivers webhooks to listeners (written in Golang)
Only Postgres DB is needed.

Manually create "supported_chain" in db

go clean -testcache
