What is Sanctum Infinity (INF)?

Quick Facts

• Blockchain: Solana
• Token type: Liquid staking token (LST)
• Yield sources: Staking rewards + trading fees
• Pool type: Multi-LST liquidity pool
• Token model: Reward-bearing (not rebasing)
• Instant unstaking: Available with a small fee
• DeFi compatible: Usable across Solana DeFi protocols

Introduction

Sanctum Infinity is Solana's first multi-LST liquidity pool, designed to unify fragmented liquid staking liquidity across the ecosystem. Its native token, INF, represents a proportional share of the pool's total staked SOL value and automatically accrues yield just by being held.

The Sanctum protocol sits behind many of Solana's largest liquid staking tokens, including JupSOL, dSOL, and bbSOL, positioning INF as the flagship product of the broader Sanctum ecosystem.

History & Background

Sanctum evolved from Socean, an early noncustodial stake pool on Solana. As liquid staking on Solana expanded — growing from a handful of LSTs to over 1,000 — the need for shared, deep liquidity became clear. Sanctum launched the Infinity pool to solve the fragmentation problem, enabling any supported LST to tap into a shared liquidity layer.

How Sanctum Infinity Works

Infinity holds a curated basket of high-performing LSTs. When users deposit SOL or any supported LST, they receive INF tokens in return. The pool earns yield from two sources simultaneously:

• Staking rewards — the weighted-average yield from all LSTs in the pool
• Trading fees — generated whenever users swap between LSTs through Sanctum's router

A dynamic fee structure adjusts based on each LST's share of the pool, encouraging rebalancing trades and reducing concentration risk. Because INF is a reward-bearing token, its value grows relative to SOL over time rather than minting new tokens for holders.

Tokenomics

INF is minted when users deposit SOL or LSTs into the Infinity pool and burned upon withdrawal. There is no fixed cap — the supply reflects pool participation. Its economic design prioritises sustainable, real yield: returns come from genuine staking activity and swap fee revenue, not token inflation. Sanctum also has a separate governance token, CLOUD, which governs broader protocol decisions.

Ecosystem & Use Cases

Because INF is an SPL token, it plugs directly into Solana DeFi. Holders can use INF as collateral for lending, provide liquidity on DEXs, or simply hold it to earn compounding yield. Instant unstaking is available through the Infinity AMM for a small 0.1–0.3% fee, making it practical for active traders who need to rotate collateral quickly.

Team, Governance & Community

Sanctum is the team behind the protocol, with roots in the Socean project. Governance is handled through the CLOUD token, enabling community participation in key protocol decisions. The project has integrated with major Solana wallets and aggregators including Jupiter and Solflare.

Advantages

• Dual yield — earns both staking rewards and swap fees, outperforming single-validator LSTs
• Deep shared liquidity — all LSTs benefit from the pool's combined depth
• No lockups — instant unstaking available at any time
• DeFi-ready — directly usable as collateral or in liquidity strategies
• Diversification — exposure to a basket of LSTs reduces single-validator risk

Risks & Challenges

• Smart contract risk — bugs or exploits in pool contracts could affect funds
• LST depeg risk — if a held LST depegs, the pool's overall value can be impacted
• Concentration risk — if the pool grows too large in one LST, fee incentives must rebalance it
• Solana ecosystem dependency — performance is tied to the health of the Solana network

Long-Term Vision

Sanctum's stated mission is to 'make all SOL liquid.' Infinity is the cornerstone of that vision — a universal liquidity layer where every LST, large or small, can thrive. As the Solana staking ecosystem continues to grow, Infinity aims to be the default destination for yield-seeking SOL holders seeking both simplicity and optimised returns.
