Sanctum Development Guide

A comprehensive guide for building Solana applications with Sanctum - Solana's largest LST (Liquid Staking Token) platform powering 1,361+ LSTs.

Overview

Sanctum provides unified liquid staking infrastructure on Solana:

Infinity Pool: Multi-LST liquidity pool with zero-slippage swaps

Router: Instant LST-to-LST swaps via stake account routing

Reserve: Instant SOL liquidity for LST withdrawals

LST Creation: Launch custom liquid staking tokens

INF Token: Yield-bearing token representing Infinity pool shares

Key Stats

1,361+ LSTs supported

$1.4B+ in swap volume facilitated

~8,000 SOL ($1M+) in fees shared with stakers

Partners: Jupiter (jupSOL), Bybit (bbSOL), Drift (dSOL), crypto.com (cdcSOL)

Quick Start

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();
