sanctum

Request a quote from the Sanctum API's /swap/token/order endpoint with input mint, output mint, amount, mode, and signer, then sign the returned base64 transaction and submit it to /swap/token/execute. The router automatically selects Infinity, Router, or Reserve as the swap source.

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

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

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

Yes, use the /swap/depositStake/order endpoint with the stake account public key and desired output LST mint, then execute the signed transaction via /swap/depositStake/execute. The stake account must be active and delegated to a validator supported by the target pool.

Infinity pool swaps charge 8 bps and INF withdrawals charge 10 bps, with 90% of fees going to liquidity providers. Router operations range from 0 to 10 bps, and StakeWrappedSol carries no fee.
