Welcome to Compass API
Compass is a non‑custodial API for on‑chain finance. Add Earn, Swap, Borrow, Leverage, Monitoring, and more to your product with a few lines of code. No smart contracts and protocol integrations required. Multi‑step strategies run as one safe, atomic transaction with the Transaction Bundler. Our mission: make on‑chain finance products as easy to build as any Web2 product. The Compass API and SDKs let you ship on‑chain features in days while we handle the blockchain plumbing. Whether you’re a wallet, fintech, trading platform, or crypto super app, use Compass to grow users and revenue, without new smart contracts or protocol maintenance.We launched Compass Transaction Bundler: build and execute complete DeFi workflows in one atomic transaction, without writing or deploying smart contracts.

Key features
- Unified API: 90+ actions across DeFi (swap, lend, borrow, LP, leverage, monitor, and more); same interface for data (historic and real-time) and execution across all protocols.
- Always non‑custodial: we return unsigned payloads; you (or your users) sign. Works with EOAs, custodians, and smart accounts like Safe and ZeroDev.
- Intent bundles: Bundle multiple DeFi actions across protocols in a single request, cutting failures, partial flows, and saving ~50–70% gas. Read more here.
- Python & TypeScript SDKs: Fast and easy-to-use Python and TypeScript SDKs so you can focus on building incredible products.
- Agent-ready: Compass LangChain toolkit; works with any supported LLM.
