Description

Relayer service that makes calls to the smart contracts. Now it is used to work with such endpoints:

/integrations/registration-relayer/v1/register - it takes calldata in hex encoided format from Rarime mobile applications and makes call to the smart contract.

Request body example:
```
{
  "data": {
    "tx_data": "hex_encoded_call_data",
    "destination": "contract_address,optional"
  }
}
```

git clone github.com/rarimo/registration-relayer
cd registration-relayer
go build main.go
export KV_VIPER_FILE=./config.yaml
./main run service

Documentation

We do use openapi:json standard for API. We use swagger for documenting our API.

To open online documentation, go to swagger editor here is how you can start it

  cd docs
  npm install
  npm start

To build documentation use npm run build command, that will create open-api documentation in web_deploy folder.

To generate resources for Go models run ./generate.sh script in root folder. use ./generate.sh --help to see all available options.

Note: if you are using Gitlab for building project docs/spec/paths folder must not be empty, otherwise only Build and Publish job will be passed.
