Sanctum

Sanctum is a liquid staking protocol and LST infrastructure layer built on Solana. Launched in 2023, Sanctum enables SOL holders to stake their tokens through a growing set of validator-specific liquid staking tokens, each of which remains tradeable and composable within the Solana DeFi ecosystem. Rather than operating as a single staking pool, Sanctum functions as shared staking infrastructure that allows multiple validators to issue their own branded LSTs while pooling liquidity to reduce fragmentation across the staking market

When a user stakes SOL through a Sanctum-supported LST, they receive a token that represents their staked position and accrues validator rewards over time. These LSTs are fully transferable and can be used across Solana protocols that accept SPL tokens, meaning stakers are not forced to choose between earning staking rewards and participating in DeFi applications. The LST can be redeemed for the underlying staked SOL at any point, subject to the standard Solana unstaking epoch cycle

Sanctum's architecture coordinates staking flows between users, validators, and the shared Infinity liquidity pool. When a user wants to exit a specific LST position, they do not necessarily need to wait through an unstaking delay — instead, they can swap their LST into another supported LST or into SOL using the Infinity pool, which aggregates staked SOL reserves across all participating validators. This design addresses one of the core liquidity challenges that has historically limited adoption of validator-specific staking tokens on Solana

Sanctum's core infrastructure is built around the concept of permissionless LST creation. Any Solana validator can launch a custom LST through Sanctum without requiring approval from a central authority. The LST is backed by the validator's stake pool, and its token price reflects the accumulation of staking rewards over time. This design allows validators to offer their own branded staking product and build a direct relationship with delegators beyond what is possible through native Solana staking

Each validator LST on Sanctum follows the SPL stake pool token standard, which is the foundational specification for staking tokens on the Solana network. This standard ensures that all LSTs behave consistently at the protocol level, allowing wallets, DEXs, and lending protocols to integrate any Sanctum LST using the same interface they would use for any other SPL token. Consistency at the token standard level is a prerequisite for meaningful DeFi composability, and Sanctum builds directly on this foundation

The staking infrastructure managed by Sanctum includes a router mechanism that directs newly staked SOL into the appropriate validator pool depending on the LST a user selects. This routing layer is designed to keep individual validator pools adequately funded while maintaining the user experience of a simple token-for-stake transaction. Users interacting through the Sanctum app interface do not need to understand validator selection, epoch timing, or stake account mechanics — these are abstracted away by the protocol

Developer access to Sanctum is supported through the public documentation at learn.sanctum.so and through the open repositories available at github.com/igneous-labs. Protocol integrators can use these resources to inspect stake pool mechanics, LST token mint configurations, and the Infinity pool interface. The availability of technical documentation and open-source code enables third-party wallets, aggregators, and DeFi protocols to integrate Sanctum LSTs without relying on proprietary APIs or closed contracts

The Infinity pool is Sanctum's shared liquidity reserve that allows users to swap between any supported LST without waiting for an unstaking epoch to complete. The pool holds reserves of multiple validator LSTs and manages rebalancing to maintain adequate liquidity for each supported token. By aggregating staked SOL liquidity across validators, Infinity reduces the fragmentation that would otherwise make each individual validator LST illiquid and difficult to use in time-sensitive DeFi transactions

CLOUD is the native token of the Sanctum protocol, used for governance participation and as a utility token within the ecosystem. CLOUD tokens are distributed to participants who engage with the Sanctum staking infrastructure, creating an alignment between protocol usage and token holder incentives. Governance proposals and protocol parameters are subject to CLOUD holder voting, allowing the community to influence the direction of the protocol without relying on a centralized development team for all decisions

Sanctum's liquid staking infrastructure serves several distinct use cases within the Solana ecosystem. Individual SOL holders benefit from the ability to earn staking rewards while maintaining access to their capital through an LST that can be deployed in lending protocols, liquidity pools, or other DeFi applications. Validators use Sanctum to create differentiated staking products and grow their delegator base beyond the standard Solana staking interface. Protocol developers and DeFi builders can incorporate Sanctum LSTs into their own products using SPL token integrations without custom staking logic

Sanctum addresses a structural gap in the Solana staking ecosystem by providing shared LST infrastructure that reduces liquidity fragmentation and makes validator-specific staking tokens usable within DeFi. Its combination of permissionless LST creation, the Infinity liquidity pool, and adherence to the SPL stake pool standard positions it as a meaningful building block for Solana staking infrastructure. Users looking to stake SOL with maintained liquidity and developers building staking-adjacent products will find Sanctum's open documentation and protocol design to be a well-structured and factually grounded foundation
