SDK 3.0.0 / API 2026-09.caucasus

​
Rhinestone SDK v3 and Caucasus API

SDK v3 adopts the 2026-09.caucasus API for EVM and Solana transactions. Direct HTTP integrations pin it with x-api-version: 2026-09.caucasus.
  • Solana accounts and execution: Configure EVM and Solana accounts independently, fund transactions from Solana, and run native Solana instructions.
  • Explicit funding: Select one source chain/token and one destination token instead of relying on automatic or multi-source funding.
EVM-only integrations also need to migrate.Migrate from SDK v2 to v3 · Migrate from Blanc to Caucasus

​
Unified onramp API

One order model for fiat checkouts and exchange connections.
  • Start an order: POST /onramp/orders returns a hosted checkout for kind: "fiat" or kind: "exchange".
  • Track every order: GET /onramp/orders and GET /onramp/orders/{id} report each order stage by stage, for good, including pending and cancelled ones.
  • Complete means landed: an order is completed once its crypto arrived on-chain as a deposit; exchange orders now reach a terminal state too.
  • Push updates: the ramp-order webhook sends the whole order on every stage move.
  • List options: GET /onramp/options returns fiat payment methods or exchange connections.
The /onramp/swapped/* routes and the onramp-order webhook are deprecated. They keep working unchanged until their retirement is announced.Create an onramp checkout

SDK 2.0.0

​
Rhinestone SDK v2

A ground-up rework of the SDK aligned with the Blanc API.
  • Non-EVM destinations: Settle transactions to Solana and Tron.
  • Multi-route quotes: prepareTransaction returns quotes: { best, all }; sign the recommended route or select another.
  • Simplified intent lifecycle: IntentStatus uses PENDING, COMPLETED, and FAILED, with a flat per-chain operations[] shape.
  • Settlement control: Include or exclude specific bridges for each transaction.

API 2026-04.blanc

​
Blanc API

A major revision of the Intents API, introduced with x-api-version: 2026-04.blanc. See API versioning for current integration guidance.
  • Non-EVM destinations: Settle transactions to Solana and Tron.
  • Destination executions on more layers: Run calldata on the destination after bridging across supported settlement providers.
  • Multi-route quotes: POST /quotes returns server-ranked routes[].
  • Improved cost reporting: Each route has one cost object with input, output, and a fee breakdown.
  • Server-stored intents: A quote returns an intentId; submit signatures by ID instead of returning the complete intentOp.
  • Server-provided EIP-712: Pass signData directly to wallet.signTypedData() instead of reconstructing types in the client.
The previous 2026-01.alps version is deprecated.
