2. Gateway / Relay Layer

Purpose:

Acts as the adapter/interface between your aggregator and various external DePIN networks.

Responsibilities:

• Normalize protocol-specific communication: REST, libp2p, GraphQL, JSONRPC, gRPC.

• Translate aggregator-standard queries into each DePIN’s format.

• Handle authentication (e.g. API tokens, wallet signatures, access keys).

• Serve as a lightweight proxy to route data and commands.

Examples:

• Filecoin gateway using IPFS API or Lotus JSON-RPC.

• Helium gateway using their Console APIs or MQTT relays.

• DIMO connector fetching vehicle data via VIN & user permission tokens.
