Flare Node Proxy

Description

This app works as a proxy with public Flare API providers in mind. It includes a middleware that blocks transactions to the PriceSubmitter contract by default. It doesn't modify, record, or do anything with the request other than rejecting transactions to the PriceSubmitter contract (0x1000000000000000000000000000000000000003).

It uses GoFiber's Proxy to forward requests to the specified endpoint, the requests should get there intact, and come back intact too. And it also uses goccy/go-json to make JSON marshalling/unmarshalling faster.

TODO

• Handle proxy to websockets
• Fix reading whitelist file from the current running directory, for some reason the watcher doesn't emit events
• Implement expiration dates for whitelisted addresses

How to use

Start the application

go run app.go --monitor --port :3000 --endpoint http://localhost:9650 --watchlist "/path/to/whitelist/file.json"
