Events Indexed

Factory Events:

• NewERC721Pair - When a new ERC721 pool is created
• NewERC1155Pair - When a new ERC1155 pool is created
• ERC20Deposit - ERC20 token deposits into pools

Pair Events (dynamically indexed):

• SwapNFTInPair - NFTs swapped into pool (buy)
• SwapNFTOutPair - NFTs swapped out of pool (sell)
• SpotPriceUpdate - Spot price changes
• TokenDeposit / TokenWithdrawal - Token liquidity changes
• NFTWithdrawal - NFT withdrawals
• DeltaUpdate - Bonding curve delta changes
• FeeUpdate - Fee changes
• AssetRecipientChange - Asset recipient changes

Setup

1. Install dependencies:

npm install

2. Generate TypeScript types:

npm run codegen

3. Build the subgraph:

npm run build

Deployment

Deploy to The Graph Studio (Hosted Service)

1. Create a subgraph on The Graph Studio
2. Get your deployment key
3. Deploy:

npm run deploy

Deploy Locally

1. Start a local Graph node (see Graph Node docs)
2. Create the subgraph:

npm run create-local

3. Deploy:

npm run deploy-local

Schema

The subgraph indexes:

• Pool entities - All pool configurations and current state
• Swap entities - All buy/sell transactions
• Deposit entities - All deposits (NFTs, tokens, ERC1155)
• Withdrawal entities - All withdrawals

Query Examples

# Get all pools for a specific NFT contract
{
  pools(where: { nftContract: "0x..." }) {
    id
    spotPrice
    poolType
    currentNFTBalance
    currentTokenBalance
  }
}

# Get all swaps for a pool
{
  swaps(where: { pool: "0x..." }, orderBy: timestamp, orderDirection: desc) {
    id
    type
    tokenAmount
    nftIds
    timestamp
  }
}

Development

• npm run codegen - Generate types from schema and ABIs
• npm run build - Build the subgraph
• npm run deploy - Deploy to The Graph Studio
• npm test - Run tests (if configured)
