mSOL

The liquid staking token issued by Marinade Finance when users stake SOL through the protocol, representing staked SOL that earns Solana network staking rewards while remaining freely tradeable and usable in DeFi applications. When a user deposits SOL into Marinade, they receive mSOL tokens that appreciate in SOL terms over time as staking rewards accumulate; rather than rebasing (increasing mSOL balance), the exchange rate between mSOL and SOL increases, so one mSOL becomes worth increasingly more SOL as rewards compound. Marinade's delegation algorithm distributes the pooled SOL across hundreds of Solana validators using a scoring system that optimizes for yield while avoiding excessive concentration in any single validator, contributing to Solana's stake decentralization. mSOL can be used as collateral in Solana lending protocols, as liquidity in DEX pools, and in yield aggregators, enabling liquid staking participants to continue earning DeFi yields on top of their staking base. Example: During Solana's DeFi expansion in 2021 and again in 2024, mSOL became a foundational collateral asset in Solana's lending protocols, with significant TVL deposited in Solend and Marginfi as collateral for SOL-denominated or stablecoin loans. This composability allowed stakers to earn both staking yield and DeFi yield simultaneously on the same capital, demonstrating liquid staking's capital efficiency advantage over native staking. Why it matters for Web3: mSOL is Solana's original liquid staking token and established the liquid staking primitive on Solana as Lido did on Ethereum. Its architecture, particularly Marinade's validator diversification strategy, demonstrates that liquid staking protocols can be designed with network health objectives rather than purely yield optimization, providing a model for how DeFi infrastructure can create positive externalities for the broader ecosystem it depends on.
