Dual SDK: Frontend and Server
SDKAPIIntegration
May 6, 2026

Two SDKs, two auth modes

Blend now supports both browser-based and server-side integrations.
  • @blend-money/fe replaces @blend-money/sdk for frontend apps. Uses publishable keys and SIWE wallet signing.
  • @blend-money/node is a new server SDK for backends using Privy, Turnkey, or other embedded wallet providers. Uses API keys (sk_live_).
  • Both SDKs share business logic from @blend-money/core - same quote format, intent lifecycle, and amount helpers.
  • API routes restructured: /sdk/* becomes /extern/fe/* (frontend) and /extern/svr/{accountTypeId}/* (server).
  • New Credentials admin page for managing SIWE domains, signing key rotation, and API keys.
  • JWT revocation: per-token sign-out via Redis blocklist, plus org-wide key rotation for security incidents.
See Authentication for how the two modes work.
Frontend SDK and Intent Sessions
SDKAPIIntegration
May 4, 2026

SDK docs updated for publishable keys and SIWE

Integration docs now reflect the frontend-first SDK flow: BlendSdk runs in the app with a client-safe publishableKey, users authenticate with SIWE, and deposits and withdrawals use transaction-intent quote and execution sessions through the Blend /sdk backend.
