Sanctum

API Setup

const SANCTUM_API_BASE = 'https://sanctum-api.ironforge.network';

// All endpoints require API key
const headers = {
  'Content-Type': 'application/json',
};

// Example: Get all LST metadata
const response = await fetch(
  `${SANCTUM_API_BASE}/lsts?apiKey=${API_KEY}`
);
const lsts = await response.json();

Core Concepts

1. LST (Liquid Staking Token)

LSTs represent staked SOL that remains liquid. When you stake SOL through a stake pool:

• You receive LST tokens representing your stake
• The stake earns validator rewards
• LSTs can be traded, used in DeFi, or swapped back to SOL

2. INF Token

INF is Sanctum's flagship yield-bearing token:

• Represents share of Infinity pool's multi-LST holdings
• Reward-bearing: Value increases vs SOL (not rebasing)
• Earns weighted average of all LST yields + trading fees
• No lockups - hold to earn, swap out anytime

// INF increases in value over time
// Example: 1 INF deposited at 1.0 SOL might be worth 1.05 SOL later
const infValue = await getInfSolValue(); // Returns current INF/SOL rate

3. SOL Value Calculators

On-chain programs that convert LST amounts to intrinsic SOL value:

// Each LST has a dedicated calculator
const SOL_VALUE_CALCULATORS = {
  SPL: 'sp1V4h2gWorkGhVcazBc22Hfo2f5sd7jcjT4EDPrWFF',

  SanctumSplMulti: 'ssmbu3KZxgonUtjEMCKspZzxvUQCxAFnyh1rcHUeEDo',
  Marinade: 'mare3SCyfZkAndpBRBeonETmkCCB3TJTTrz8ZN2dnhP',
  Lido: '1idUSy4MGGKyKhvjSnGZ6Zc7Q4eKQcibym4BkEEw9KR',
