Developer SDK & API (Planned)
The Solident SDK and API are currently in development and not yet available for public use.
This section outlines the design goals, planned features, and early concepts of how integration will work once released.
"For developers, integration should feel as simple as adding OAuth — but with biometric-grade security under the hood."
Planned Goals
Provide a drop-in SDK for Solana dApps to integrate Solident login.
Replace seed phrase logins with biometric session tokens.
Make it simple for developers to verify sessions and request signatures.
Support multi-chain integration in the future, starting with Solana.
Expected SDK Features
Biometric login hook: Prompt Solident app to authenticate (face + pattern).
Session token retrieval: Securely obtain a short-lived session token tied to the user’s device.
Token verification API: Endpoint for dApps to verify validity of session tokens.
Transaction signing: Request local signing via Solident, never exposing private keys.
Cross-device continuity: Support for users switching between desktop and mobile.
Planned API Endpoints
(draft, subject to change)
POST /auth/session Request a new session token after user authentication.
GET /auth/verify Validate whether a session token is active and tied to a Solident identity.
POST /transaction/sign Submit raw transaction data to be signed locally by the user’s device.
GET /wallet/balance Return balances for SOL and SPL tokens tied to the authenticated user.
Developer Roadmap
Phase 3: Initial SDK + API release for Solana dApp login.
Phase 4: SDK expansion for multi-chain and external integrations.
Beyond: Community-driven governance for SDK updates and open standards.
Current Status
SDK is not yet released.
Documentation here serves as a preview of what developers can expect.
Feedback is welcome, integration priorities may evolve with community input.
The Solident SDK & API will turn Solident from a standalone wallet into a biometric login layer for all dApps. Once available, developers will be able to onboard users with the same ease as Web2 apps, but with the trust of biometric-first security.
