Cosmos RPC Transport Research for IPI

Generated-client and browser comparison workspace for Cosmos gRPC-Web and gRPC-Gateway query paths.

What the source contains

• a Cosmos, IBC, and CosmWasm protobuf tree under proto/;
• separate generated TypeScript clients under codegen_grpc_web/ and codegen_grpc_gateway/;
• generator scripts for both transports; and
• Next.js comparison pages at /grpc-web and /grpc-gateway.

The repository evaluates how equivalent Cosmos queries can be represented and called through two web-facing transports. It is not an RPC server, canonical IPI SDK, independently verifying light client, or configured IPI network client.

Development

This codebase derives from an older Create Cosmos App / Next.js example. Review its dependency and protocol versions before exposing a deployment.

yarn
yarn dev
yarn build

Regenerate both client trees with:

yarn codegen

Integration requirements

An IPI-integrated version needs pinned protobuf source revisions, reproducible generated output, configured and displayed chain/endpoint identity, equivalent response fixtures across transports, untrusted-response handling, and tests against a versioned public node interface.

Development status

Integration research. The client-generation surface is substantial but inherited from Hyperweb's grpc-web-grpc-gateway example, and no IPI-specific endpoint or schema delta is implemented. Generated clients are transport code, not proof that returned state is canonical or independently verified.
