Sentinel SDKs

Three SDKs are available for building on Sentinel. Each one covers a different language and use case, but they all let you query chain state, manage subscriptions and sessions, and connect to dVPN nodes.

Golang SDK

Full-stack SDK built on Cosmos SDK. Blockchain client, node communication, and native WireGuard/V2Ray/OpenVPN tunnel management.

Javascript SDK

CosmJS-based SDK for browser and Node.js. Queries, signing, WebSocket events, and VPN session handshakes.

Python SDK

gRPC-based SDK for scripting and backend services. Node queries, subscription management, and session handling.
