What is Sanctum?
Sanctum is a liquid staking protocol and infrastructure layer on Solana that lets validators, decentralized applications, and centralized exchanges launch custom liquid staking tokens (LSTs). Instead of fragmenting staking balances across isolated pools, Sanctum links them through unified liquidity reserves and lets holders trade across hundreds of tokens.
Team and governance
Led by FP Lee, the engineering team behind Sanctum has built on Solana since 2021, directly contributing to Solana Labs' reference stake pool program. Sanctum operates as a decentralized infrastructure provider governed via its CLOUD ecosystem token. The protocol safeguards program modifications through an 11-member multisig upgrade authority that includes ecosystem partners such as Jupiter, Jito, Sol Strategies, and Solblaze.
Staking mechanics and architecture
The protocol runs on non-custodial Solana smart contracts. Its core components include the Infinity pool, the Sanctum Router, and the Reserve. The Infinity pool is a multi-LST liquidity engine that accepts deposits of supported LSTs or SOL, returning the yield-bearing receipt token INF. The Router calculates swap pathways across validators and pools to enable instant conversions between native SOL and niche validator tokens without unbonding delays. Major platforms rely on Sanctum's framework to deploy branded tokens, including Jupiter (jupSOL), Bybit (bbSOL), and Drift (dSOL).
Fees and operational costs
Staking directly into automated Sanctum LSTs incurs a 10% epoch fee split equally between node operators and Sanctum. Standard LST redemptions via stake or SOL withdrawal instructions charge 0.10% (10 basis points). Using the Sanctum Router to deposit stake costs 10 basis points, while SOL withdrawals cost 1 basis point. Within the Infinity pool, 90% of swap fees flow to liquidity providers, with 10% allocated to the protocol vault.
Track record and audits
Total value locked across Sanctum reached approximately $1.81B to $2.07B in October 2026, holding over 1,361 deployed LSTs. In June 2026, the team debuted mobile staking applications for iOS and Android, followed by the Sanctum App 2.0 release in October 2026 featuring integrated Squads multisig security. The protocol codebase has completed audits by Halborn, Kudelski Security, OtterSec, Neodyme, and Quantstamp, while the Reserve program underwent an audit by Sec3.
Risks and limitations
Stakers face smart contract vulnerabilities inherent to complex pool routing. Receipts also bear slashing exposure and underperformance risk from individual validator nodes backing custom tokens. During extreme market volatility or heavy liquidations, secondary market LST depegs can occur if Infinity pool reserves deplete before underlying epoch unbonding finishes.

Pros and cons
Pros
- Connects over 1,360 Solana liquid staking tokens into shared liquidity
- Audited by six firms including Quantstamp, OtterSec, and Halborn
- Program upgrades secured by an 11-member multi-organization multisig
- Enables immediate unbonding through liquidity pools rather than epoch waits
Cons
- Withdrawal instructions incur a 0.10% fee
- Restricted exclusively to the Solana blockchain
- Underlying custom LSTs remain subject to individual validator slashing risks
- Secondary pool trades face potential depeg risk during liquidity shocks
Our review
4.5/5
Excellent
Sanctum offers deep liquidity and instant swaps across more than 1,361 Solana LSTs, but users face epoch-based management fees and smart contract risks across multiple interconnected pools.
Sanctum is the primary liquidity and token infrastructure powering Solana liquid staking, hosting over 1,361 liquid staking tokens (LSTs) including jupSOL, bbSOL, and dSOL. Its architecture replaces isolated staking pools with a unified liquidity system centered on the Infinity pool, which issues the yield-bearing receipt token INF, alongside the Sanctum Router for low-impact swaps between SOL and various LSTs.
The protocol yields between 5.65% and 5.69% APY on staked SOL as of October 2026. Sanctum LSTs charge an epoch fee of 10% on staking rewards, split evenly between node operators and the protocol, along with a 0.10% withdrawal fee on withdraw SOL and withdraw stake transactions. Standard routing incurs no base fee, but the Sanctum Router charges 1 basis point on SOL withdrawals and 10 basis points on stake deposits. Total value locked exceeded $2.07 billion in October 2026, giving it the largest liquidity footprint among Solana staking protocols.
Protocol security relies on multiple completed audits from Halborn, Kudelski, OtterSec, Neodyme, Quantstamp, and Sec3. Program upgrade authority is governed by an 11-member multisig that includes ecosystem participants like Jupiter, Jito, and Solblaze. However, users still bear smart contract risk across the underlying SPL stake pool program and the Infinity pool. Holding custom LSTs also exposes stakers to potential validator underperformance or depeg events if pool balances become imbalanced.
Sanctum suits Solana users seeking flexible staking yields without sacrificing liquidity across custom validator tokens. Stakers wanting a single, straightforward validator pool with lower administrative layers may prefer standard native staking or isolated liquid staking providers like Jito.

In 2025, at least $713M was stolen from people's personal crypto wallets.
80,000 victims across 158,000 wallet compromises.
Of the $604M where the cause is public:
~71% ($430M) - wallet access stolen through social engineering or malware 🦠
~14% ($84M) - signed malicious transaction ⚠️
~8% ($50M) - lookalike address copied from transaction history 📋
~7% ($41M) - physical attacks 🔧
We can’t stop all of this, but we can make sure one leaked key isn’t enough to empty your wallet.
