Gheedra GEX

These files contain the smart contract code and associated tests for Gheedra's GEX platform.

Contract Deployment

Run Tests

  1. In a terminal window run yarn t

Run Contract Tests & Get Callstacks

  1. In one terminal run yarn buidler node
  2. Then in another run yarn t

Deploy Locally

  1. First start up a server: yarn buidler node
  2. Then run (in a different terminal tab): yarn deploy

Deploy to Ethereum

  1. Create/modify network config in buidler.config.ts and add API key and private key
  2. Run yarn buidler run --network goerli scripts/deploy.ts

Verify on Etherscan

  1. Add Etherscan API key to buidler.config.ts
  2. Run yarn buidler verify-contract --contract-name <CONTRACT_NAME> --address <DEPLOYED_ADDRESS>

The Graph Deployment

This process deploys the GEX subgraph to The Graph

1. Update config

In subgraph.yaml, update the following

  1. Set repository to your github repository (must be public for the deployment only)
  2. Set address to the address where the contract is deployed
  3. Set startBlock to 1 block before contract deployment

Note: your subgraph github repository must be public for deployment, but can be set back to private once deployed

2. Build locally

  1. Code generation (run after changes to GraphQL schema or contract ABIs): yarn graph codegen
  2. Build (final step before deployment): yarn graph build

3. Set your access token

  1. Login to The Graph and retrieve your access token
  2. Run graph auth https://api.thegraph.com/deploy/ <YOUR ACCESS TOKEN> to authorize deployment

4. Deploy

  1. Run graph deploy <SUBGRAPH_NAME> --ipfs https://api.thegraph.com/ipfs/ --node https://api.thegraph.com/deploy/ to deploy the graph
