Gravity Node Data Extractor

Gravity Node Data Extractor

Abstract

This package represents working example of Gravity Data Extractor.

I. Running public Docker image

1. Pull the image

docker pull gravityhuborg/gravity-data-extractor:master

2. Run

You can run SuSy dApp extractor

docker run -itd -p 8090:8090 gravityhuborg/gravity-data-extractor:master

2.1 Run SuSy dApp extractor for EVM-based or WAVES-based chains

Currently, extractor supports only EVM-chain<->WAVES direction. So we in order to add new custom(non-EVM) chain we need to provide 4 additional params and 2 bridge implementations as well - for direct and reversal swaps.

So, for EVM-based tokens we run --waves-based-to-eth-direct and --waves-based-to-eth-reverse. For WAVES-based tokens we run --eth-based-to-waves-direct and --eth-based-to-waves-reverse

II. Running the binary

1. Install Go

2. Build the binary

go build -o data-extractor

3. Run it with appropriate params

./data-extractor --api 'thekey' --pair 'WAVESBTC' --port 8099

Miscellaneous

1. Run tests

go test tests/*.go -v

2. Ergo extractors

Ergo extractors are under development. At this moment, we developed erg-erg extractors to test gravity on our network. We add other extractors when all tests passed.
