Celo Composer Subgraph

Requirements​

  • The graph cli
  • Contracts deployed with Hardhat with deployment information saved in packages/hardhat/deployments/hardhat_contracts.json
  • Run yarn get-abi to print contract info and save ABI to packages/subgraphs/abis. Enter the network that the contract you want to watch is deployed at, and the name of your contract. This script reads the hardhat deployment info from packages/hardhat/deployments/hardhat_contracts.json.

This README was created following this post. Consult it for more detailed information.

Setup​

Run

graph init
  • Select ethereum as the protocol.
  • Select hosted-service
  • Name your subgraph following the convention github-username/subgraph-name
  • Select celo-alfajores as the network (or celo for mainnet)
  • Enter the appropriate contract address (printed when you ran yarn get-abi)
  • Enter the path to the ABI (also printed when you ran yarn get-abi)

cd into the new directory

Run

graph codegen
graph auth --product hosted-service <ACCESS_TOKEN>

Deploy​

graph deploy --product hosted-service <GITHUB_USER>/<SUBGRAPH NAME>

It will take some time for the Graph to sync your subgraph. You can view the progress on the Graph's hosted service dashboard.

Reference​

You can view an example subgraph mapping, schema and subgraph manifest file in the ./storage-subgraph folder. Note that this folder is missing the autogenerated files that the graph cli tool generates when you go through the steps above.
