pub const ADDRESS: &str = "0x73DA73EF3a6982109c4d5BDb0dB9dd3E3783f313";
const START_BLOCK: u64 = 12129118; - name: map_transfers
kind: map
initialBlock: 12129118
inputs:
- source: sf.ethereum.type.v2.Block
output:
type: proto:schema.TransfersWe now need to recompile our WASM binary with the new changes we made to the rust files.
We need to bundle the protobuf definitions and the WASM binary into a single file. This is what we will deploy the subgraph.
This endpoint will change if you are deploying to the hosted service or decentralized network. But replace this with the command that is appropriate for your setup.
