Cosmos RPC Proxy

JSON-RPC 2.0 proxy to the Cosmos RPC of a supported Cosmos chain. The request and response follow the standard JSON-RPC 2.0 specification.

Only a limited set of RPC methods is supported:

• status — fetch the node status. params must be {}.
• abci_query — query application state. params must include data (string), path (string), and prove (boolean). Allowed path values:
  • /cosmos.auth.v1beta1.Query/Account
  • /cosmos.bank.v1beta1.Query/AllBalances
  • /cosmos.tx.v1beta1.Service/Simulate
• broadcast_tx_sync — broadcast a signed transaction. params must contain a single tx field (string).
• tx_search — search for transactions. params must include page (string, only "1" is allowed) and query (string, must match tx.hash='<64-hex>').

Any other method or unsupported parameter shape returns a 400 error.
