TheGraph: one graph-node for several blockchains?

graph-node from TheGraph can get data from blockchain.

From https://github.com/graphprotocol/graph-node/blob/master/docs/getting-started.md

cargo run -p graph-node --release -- \
  --postgres-url postgresql://<USERNAME><:PASSWORD>@localhost:5432/<POSTGRES_DB_NAME> \
  --ethereum-rpc <ETHEREUM_NETWORK_NAME>:https://mainnet.infura.io \
  --ipfs 127.0.0.1:5001 \
  --debug

So running with --ethereum-rpc mainnet:https://mainnet.infura.io

But how to have one graph-node to several blockchains, e.g. one Ethereum mainnet and one Ethereum testnet ?

Solution

  • You can pass multiple --ethereum-rpc in the command

    e.g.

    cargo run -p graph-node --release -- \
  --postgres-url postgresql://<USERNAME><:PASSWORD>@localhost:5432/<POSTGRES_DB_NAME> \
  --ethereum-rpc mainnet:https://mainnet.infura.io \
  --ethereum-rpc goerli:https://...
  --ipfs 127.0.0.1:5001 \
  --debug
