    This is an example of a package that can be deployed to Substreams.
    It shows some common patterns like params, networks and imports.

# You can use the `protobuf` section to specify the protobuf files
# containing the types used by your modules.
protobuf:
  files:
    - my_type.proto
  importPaths:
    - ./proto

# The `binaries` section is used to specify the WASM binaries.
# They should be compiled each time you change your code.
binaries:
  default:
    type: wasm/rust-v1
    file: target/wasm32-unknown-unknown/release/substreams.wasm

# The `imports` section allows importing other spkg files for their modules, binaries or embedded protobuf definitions.
imports:
  # we will use the protobuf definitions from the substreams-sink-sql spkg
  sql: https://github.com/streamingfast/substreams-sink-sql/releases/download/protodefs-v1.0.3/substreams-sink-sql-protodefs-v1.0.3.spkg
  # we will use modules from the erc20-balance-changes package
  erc20: https://github.com/streamingfast/substreams-erc20-balance-changes/releases/download/v1.2.0/erc20-balance-changes-v1.2.0.spkg

modules:
  - name: filter_erc20_balance_changes
    kind: map
    #initialBlock: 0 # specified in the networks section
    inputs:
      - params: string
      - map: erc20:map_balance_changes # this is the map from the erc20-balance-changes package
    output:
      type: proto:my.type.FilteredBalanceChanges # this is the fully-qualified message name from the my_type protobuf file

  - name: db_out
    kind: map
    #initialBlock: 0 # specified in the networks section
    inputs:
      - map: filter_erc20_balance_changes
    output:
      type: proto:sf.substreams.sink.database.v1.DatabaseChanges # this message type is imported from the `substreams-sink-sql` package.

## We don't specify params here because we define it under 'networks'
# params:
#   filter_erc20_balance_changes: "addr=0x1234"

networks:
  mainnet:
    initialBlock:
      erc20:map_balance_changes: 200 # overloading an imported map
      db_out: 200
    params:
      filter_erc20_balance_changes: "addr=0x1234"

    initialBlock:
