Cosmos gRPC
Cosmos gRPC is available on Tatum for teams that want a more structured way to query chain data than plain JSON-based endpoints. Under the hood, Cosmos SDK modules expose Protobuf Query services, which means you work with strongly typed request and response messages instead of hand-rolling JSON payloads. That makes Cosmos a good fit for backends, indexers, and internal services that value predictable schemas, generated client code, and efficient binary transport.
This is an important distinction from Solana Yellowstone gRPC: Cosmos gRPC is not a live event stream. It is designed for request-response queries, not subscriptions, and there are no streaming methods in this interface. If your use case is reading balances, delegations, validators, staking data, governance state, or other module-backed chain data with a typed API, Cosmos gRPC is the better framing.

What you get
- Typed queries: Cosmos SDK modules expose Protobuf-based
Queryservices, so request and response shapes are explicit. - Smaller payloads: gRPC uses Protocol Buffers, which are typically more compact than JSON.
- Cleaner integrations: Generated gRPC clients reduce manual request building and response parsing across supported languages.
- Good fit for backend reads: Ideal for balances, staking, governance, validators, and other module state queries.
- REST parity when needed: Cosmos SDK can expose REST equivalents for gRPC query methods through gRPC-gateway.
