Ronin Transfer Events INGESTOR

• I couldn't read call_traces from given ronin node, therefore we are limited to scratch just the surface of EVM data. If we had transaction_traces endpoint working, we could not only see token from A to B and payment from B to A, but we would be able to see even if it was from sale or staking, therefore much richer experience. What EVM are you running? I have good experience with ERIGON
• http JSON RPC was provided. If we had websocket version (wss://...) we could create a stream and once ingestor reaches last blocks, it will continue ingesting blocks indefinitely.
• the code is quite naive and needs a lot of optimisation, like I am storing transfers one by one, we could do that in batch, etc..
• I wanted just to show how we can get the latest activity of user by just listening to events from chain.

Dependencies

• direnv (https://direnv.net/) - this will load .envrc file into terminal session so that next command like docker will have our env variables ready to use

Look into .envrc to see/change some basic configs

Run locally:

direnv allow  // to activate .envrc in terminal session
docker compose up  // to start DB and ingestor

After ingestor finishes ingesting the events from last 10000 blocks, it will die and only DB will stay running this will make postgres available locally on port 5432, make sure that port is free beforehand. While DB is up and running you can run python API to read data using new GET /events/{ronin_address} endppoint.

Migration

Migrations are automated and are run at ingestor start. Basically it checks if there is anything new to migrate or not.
