FAQ

Common questions about the Enzyme Onyx SDK and API.

---

When should I use SDK vs API?

Aspect	API	SDK
Read Data	Indexed, cached, fast (~10s cache)	Direct RPC, real-time but slower
Write Data	Not supported	Full transaction support
Historical Data	Time-series financials, past deposits	Current state only
Rate Limits	Per IP (capacity reviewed regularly)	RPC provider limits
Authentication	None required	Wallet signature for writes
Use Case	Dashboards, analytics, read-heavy apps	Deposits, redemptions, admin actions
Dependencies	None (REST/fetch)	viem, wallet provider, RPC
Offline Support	Can cache responses	Requires live RPC

Recommendation: Use a hybrid approach:

• API for reading vault data (metrics, deposits, history) - it's faster and doesn't count against RPC limits

• SDK for user transactions (deposits, redemptions, approvals) - required for blockchain writes

Example Architecture:

Your App
├── Display vault list → API (GET /vaults)
├── Show vault metrics → API (GET /vaults/{id})
├── Show user balance → API (GET /vaults/{id}/deposits/{wallet})
├── Request deposit → SDK (Components.ERC7540LikeDepositQueue.requestDeposit)
└── Approve tokens → SDK (Asset.approve)

Do I need an API key?

No. The Onyx Public API requires no authentication. You can start making requests immediately.

What's the rate limit?

The API is rate-limited per IP address. Capacity is reviewed regularly.
