Please take a look at Graph protocol for more information.

Polygon hosted node endpoints

Root

  • Mainnet: https://thegraph.com/hosted-service/subgraph/maticnetwork/mainnet-root-subgraphs
  • Goerli: https://thegraph.com/hosted-service/subgraph/maticnetwork/mumbai-root-subgraphs

For Mumbai hosted node endpoints

  • Graph node: https://mumbai-graph.matic.today
  • GraphQL endpoint: https://api.mumbai-graph.matic.today/subgraphs/name/<YOUR_GITHUB_USERNAME>/<SUBGRAPH_NAME>/graphql

Subgraphs

This repository contains subgraphs for two chains: root (Ethereum) and child (Matic) with respective testnets.

To prepare root (Ethereum) subgraphs

cd root

# install dependencies
npm install

# For goerli
npm run prepare:goerli

# For mainnet
# npm run prepare:mainnet

To prepare child (Matic) subgraphs

cd child

# install dependencies
npm install

# For mumbai
npm run prepare:mumbai

# For mainnet
# npm run prepare:mainnet

Build

# generate code
npm run codegen

# build
npm run build

Deploy locally

For goerli

# create sub graph in local node
npm run graph -- create --node http://localhost:8020/ maticnetwork/goerli-matic-subgraph

# deploy sub graph locally
npm run graph -- deploy --node http://localhost:8020/ --ipfs https://ipfs.infura.io:5001/ maticnetwork/goerli-matic-subgraph

Deploy on Graph's hosted node

For goerli

# create sub graph in local node
npm run graph -- create --node https://api.thegraph.com/deploy/  maticnetwork/goerli-matic-subgraph

# deploy sub graph locally
npm run graph -- deploy --node https://api.thegraph.com/deploy/ --ipfs https://api.thegraph.com/ipfs/ maticnetwork/goerli-matic-subgraph

For mumbai

# create sub graph in local node
npm run graph -- create --node https://mumbai-graph.matic.today  nglglhtr/mumbai-matic-subgraph

# deploy sub graph locally
npm run graph -- deploy --node https://mumbai-graph.matic.today --ipfs https://ipfs.infura.io:5001/ nglglhtr/mumbai-matic-subgraph

Run local graph node

$ cargo run -p graph-node --release -- \
    --postgres-url postgresql://localhost:5432/token-transfer \
    --ethereum-rpc http://localhost:8545/ \
