0x Exchange Proxy Subgraph (In Progress)

This is a community-run subgraph for the 0x Exchange proxy supporting all current networks from the 0x protocol. At its current state, it aims to support the following networks: ETH, Optimism, BSC, Polygon, Arbitrum, Fantom, Avalanche, Base, and Celo.

This is an extended fork from [https://github.com/0xProject/ep-subgraph].

If you are looking for a graph more focused on NFT trading look at this repo [https://github.com/DexKit/0x-nft-v4-subgraph].

Added:

  • ERC721 NFT fills
  • ERC1155 NFT fills
  • PancakeSwap call
  • NFT fill counters for maker and taker
  • OTC order
  • OTC fill counters for maker and taker

Getting Started

  • Start by installing dependencies.
yarn
  • Generate code for subgraph
 yarn codegen
  • Build subgraph for a specific network
yarn build --network <network>

where represents the supported subgraph networks: mainnet, optimism, bsc, matic, fantom, avalanche, base, arbitrum-one, celo.

How to deploy subgraph

Hosted Service

For any network supported by the protocol,

source .env; yarn codegen; yarn build --network <network>; yarn deploy --product hosted-service dexkit/0x-exchange-proxy-v4 --access-token $ACCESS_TOKEN

replace with the target network.

For instance, for Ethereum network:

source .env; yarn codegen; yarn build --network mainnet; yarn deploy --product hosted-service dexkit/0x-exchange-proxy-v4--access-token $ACCESS_TOKEN

Subgraph Deployments (TODO)

Adding a new Network

To add a new network to this graph, fill in networks.json with the respective exchange proxy address and start blocks. Next, in src/constants/network, add the network to the namespace and fill in addresses for WETH, EXCHANGE_PROXY, FLASH_WALLET, SANDBOX, and FACTORIES if applicable.

Use as source these up-to-date list of addresses

  • Deployments
  • More documentation
