Moonbeam lottery subgraph tutorial

MoonLotto Subgraph

An example Subgraph initially forked from The Graph example subgraph. Created by PureStake to get you started with The Graph on Moonbeam.

Setup

Install the node dependencies using yarn:

yarn

Create the TS types for The Graph (requires the artifacts folder created by contract compilation):

yarn codegen

Deploying contracts

For deploying contracts on Moonbase Alpha, you'll need a funded account and its private key. Store your private key for Moonbase Alpha deployment as an ENV variable:

export MOON_PRIVATE_KEY="YOUR-PRIVATE-KEY-HERE"  

Compile the contracts:

# compiles using hardhat and solc 0.8.3
yarn contract-build

To deploy to a development Moonbeam node you can run:

# deploys to moonbase alpha
yarn contract-deploy-local

To deploy to Moonbase Alpha you can run:

# deploys to moonbase alpha
yarn contract-deploy
