sanctum

Use the Sanctum API's /swap/token/order endpoint to get a quote and unsigned transaction, sign it with your wallet, then POST it to /swap/token/execute. Swaps route through the Infinity pool or Router at intrinsic SOL value with fees around 8 bps.

Request a swap quote with SOL as input and the target LST mint as output, sign the returned transaction, and execute it via the API. The same flow works for any of the 1,361+ supported LSTs including mSOL, jitoSOL, and INF.

INF is a reward-bearing token representing a share of Sanctum's Infinity multi-LST liquidity pool. Its value increases relative to SOL over time, earning the weighted average of all pool LST yields plus a share of trading fees, with no lockups.

Yes, instant unstaking swaps any LST back to SOL through the Infinity pool or Reserve for roughly 1-10 bps in fees. A delayed unstake option withdraws to a stake account with zero fees but requires waiting one to two epochs.

A 401 error means the apiKey query parameter is missing or invalid, since all endpoints require authentication. A 429 error indicates rate limiting, which you should handle with exponential backoff and by caching LST metadata responses.

Yes, Jupiter's aggregator integrates the Sanctum Router and automatically routes through it when optimal. Use the Jupiter SDK's computeRoutes with your input and output LST mints, and it will include Sanctum routes in the comparison.
