Sanctum

Sanctum functions as a liquid staking protocol and LST infrastructure layer on Solana. Launched in 2023, it enables SOL holders to stake through a growing range of validator-specific liquid staking tokens that remain fully tradable and integrable across the Solana DeFi ecosystem. Rather than relying on a single centralized pool, Sanctum provides shared staking infrastructure that lets multiple validators issue their own branded LSTs while pooling liquidity to reduce fragmentation in the staking market.

Staking SOL through a Sanctum-supported LST provides users with a token that represents their staked position and accrues validator rewards over time. These LSTs stay fully transferable and usable in any Solana protocol that accepts SPL tokens, allowing stakers to earn rewards without sacrificing DeFi participation. Redemption back to the underlying staked SOL remains available according to Solana's standard unstaking epoch schedule.

Sanctum coordinates flows between users, validators, and the shared Infinity liquidity pool. Users exiting a specific LST position avoid the unstaking delay by swapping their LST for another supported LST or SOL directly via the Infinity pool, which aggregates staked SOL reserves from participating validators. This design overcomes liquidity challenges that once limited the practicality of validator-specific tokens on Solana.

Sanctum's infrastructure focuses on permissionless LST creation. Any Solana validator can launch a custom LST through the protocol without requiring central approval. Each LST is backed by the validator's stake pool, with its price tracking accumulated staking rewards. This allows validators to offer branded staking products and build direct relationships with delegators beyond standard Solana staking options.

All validator LSTs on Sanctum follow the SPL stake pool token standard, Solana's core specification for staking tokens. This ensures consistent protocol-level behavior, so wallets, DEXs, and lending protocols can integrate any Sanctum LST using the same interfaces as other SPL tokens. Such token-level standardization underpins effective DeFi composability, which Sanctum extends seamlessly.

Sanctum operates a router that directs newly staked SOL into the corresponding validator pool based on the chosen LST. This routing maintains funding across individual pools while delivering a smooth token-for-stake experience. Users interacting via the Sanctum app interface require no knowledge of validator selection, epoch timing, or stake mechanics, as the protocol handles these details automatically.

Developers engage with Sanctum through public documentation at learn.sanctum.so and open GitHub repositories. Integrators can examine stake pool mechanics, LST mint configurations, and the Infinity pool interface. These open technical resources and code enable third-party wallets, aggregators, and DeFi protocols to incorporate Sanctum LSTs without proprietary APIs or closed contracts.

The Infinity pool serves as Sanctum's shared liquidity reserve, allowing swaps between any supported LST without waiting for an unstaking epoch. It holds reserves across multiple validator LSTs and performs rebalancing to maintain adequate liquidity for each token. By aggregating staked SOL liquidity network-wide, Infinity eliminates the fragmentation that would otherwise make individual validator LSTs illiquid and unsuitable for time-sensitive DeFi activities.

CLOUD acts as the native governance and utility token of the Sanctum protocol, distributed to participants in the staking infrastructure to align usage with holder incentives. Governance proposals and key parameters are decided through CLOUD holder voting, giving the community independent control over protocol direction. A recent governance action has now burned a substantial portion of the community reserve, reducing total supply and updating the token ticker to SANC on Solscan while preserving its core role.

Sanctum's infrastructure enables multiple use cases across the Solana ecosystem. Individual SOL holders earn staking rewards while maintaining liquidity through LSTs that can be deployed in lending, liquidity pools, or broader DeFi activities. Validators use it to launch differentiated staking products and grow their delegator base beyond standard Solana interfaces. Protocol developers and DeFi builders integrate Sanctum LSTs via standard SPL token connections without custom staking logic.

Sanctum addresses a core structural need in Solana staking by providing shared LST infrastructure that reduces liquidity fragmentation and makes validator-specific tokens viable for DeFi. Its permissionless LST creation, Infinity liquidity pool, and adherence to the SPL stake pool standard position it as a foundational component of Solana staking infrastructure. Holding leading TVL among Solana protocols, it benefits users seeking liquid SOL staking and developers building related products through its documented, open design.
