TheGraph NFT Marketplace

Quickstart

1. Install Subgraph CLI

npm install @graphprotocol/graph-cli

2. Log into the graph UI and create a new Subgraph.

Use sepolia as the network.

3. Initialize Subgraph

graph init --studio nft-marketplace

4. Authenticate CLI

npx graph auth  --studio YOUR_DEPLOY_KEY_HERE

5. Update your subgraph.yaml

• Update the address with your NftMarketplace Address
• Update the startBlock with the block right before your contract was deployed

6. Build graph locally

npx graph codegen && graph build

• graph codegen: Generates code in the generated folder based on your schema.graphql
• graph build: Generates the build that will be uploaded to the graph

7. Deploy subgraph

Replace VERSION_NUMBER_HERE with a version number like 0.0.1.

npx graph deploy --studio nft-marketplace -l VERSION_NUMBER_HERE

8. View your UI

Back in your hardhat project, mint and list an NFT with:

npx hardhat run scripts/mint-and-list-item.js --network sepolia
