Cosmoshub

Cosmos Hub anchors the IBC ecosystem using the Cosmos SDK and CometBFT consensus. Accounts are bech32 (cosmos1…), and applications interact through Tendermint RPC, gRPC, and REST. Use CosmJS or gRPC clients for transactions and queries. If you’re building cross‑chain features, plan your IBC channels and relayers alongside the app logic—you’ll treat them like first‑class infra.
