Marinade

Marinade Finance is a non-custodial Solana staking protocol that automates validator delegation through a competitive auction marketplace, giving users a choice between liquid staking tokens and direct native staking while optimizing for yield and network decentralization.

What Marinade Does

Launched in March 2021, Marinade lets SOL holders stake without picking a single validator manually. The protocol manages delegation across more than 170 validators, distributing stake according to performance and bidding behavior. Users keep custody of their assets throughout: nothing moves to a Marinade-controlled wallet. The protocol has accumulated over 8 million SOL across its staking products, making it one of the largest staking venues on Solana.

The central infrastructure powering Marinade is the Stake Auction Marketplace (SAM). Validators bid for delegated SOL in an open, transparent market. Winning bids flow back to stakers as additional yield on top of base network rewards. Because the auction is permissionless, any validator can compete, and the outcome is determined by market forces rather than committee decisions.

Staking Products

Marinade Liquid Staking issues mSOL, a yield-bearing SPL token with mint address mSoLzYCxHdYgdzU16g5QSh3i5K3z3KZK7ytfqcJm7So. When a user deposits SOL, they receive mSOL at the current exchange rate. That rate rises each epoch (approximately every two to three days) as staking rewards and MEV tips accumulate, so holding mSOL is equivalent to compounding staked SOL. mSOL can be moved freely across Solana DeFi used as collateral on Kamino, traded on Orca and Raydium, or held in a wallet while the underlying SOL continues earning rewards. Instant unstaking is available at a variable fee typically between 10 and 40 basis points; delayed unstaking (one epoch) costs 20 basis points on the mSOL path.

Marinade Native lets users stake SOL directly to validator stake accounts without receiving a liquid token, eliminating smart contract exposure for those who do not need DeFi composability. Two delegation strategies are available: Marinade Max Yield (spread across 100-plus bidding validators for maximum return) and Marinade Select (a curated set of validators with verified identities and stronger MEV oversight). Native staking TVL reached 5.3 million SOL by Q4 2025, a 21 percent quarter-over-quarter increase, and surpassed the liquid staking pool for the first time that quarter.

Protected Staking Rewards (PSR) adds a loss-absorption layer for native stakers. Validators participating in SAM must post a bond. If a validator underperforms or raises their fee mid-epoch, the bond covers the shortfall for delegators rather than passing the loss to stakers.

The USDC Vault earns yield on idle stablecoins through a Kamino Lend integration, enabling users to hold a SOL staking position and a stablecoin yield position from a single Marinade interface.

Marinade Borrow, rolled out in May 2026, added borrowing functionality, with Kamino and Jupiter Lend positions now visible directly inside the Marinade dashboard, consolidating staking and lending management in one place.

Tokens

mSOL (mint: mSoLzYCxHdYgdzU16g5QSh3i5K3z3KZK7ytfqcJm7So) is the liquid staking receipt token. It appreciates against SOL each epoch as rewards accumulate; the exchange rate is calculated using a 30-day simple moving average of 14-day APY, with MEV rewards included automatically.

MNDE (mint: MNDEFzGvMt87ueuHvVU9VcTqsAP5b3fTGPsHuuPA5ey) is the Marinade governance token with a total supply of 700 million. Holders lock MNDE on Realms to vote on protocol proposals, with a 30-day unlock commitment required for voting participation. MNDE does not accrue staking yield directly; its primary functions are DAO governance and historic liquidity-mining incentive programs used to bootstrap mSOL adoption across DeFi.

Fees

Marinade charges no deposit fee across any product. The protocol takes 6 percent of staking rewards as a performance fee, already reflected in displayed APY figures. On SAM, 75 percent of validator bids return to stakers. Instant unstake on the native side costs a dynamic market-maker fee; on the liquid side it is a swap with potential price impact. Delayed unstake is free for native staking and costs 20 basis points for mSOL, with a minimum of 1.0043 SOL.

Security and Audits

Marinade has been audited six times by five independent security firms, including Kudelski Security, Ackee Blockchain, and Neodyme. The protocol holds SOC 2 Type I and Type II certifications, an institutional compliance standard that documents security controls around its systems. Smart contracts are non-custodial by design: users retain ownership of stake accounts and mSOL at all times. The main on-chain program runs at MarBmsSgKXdrN1egZf5sqe1TMai9K1rChYNDJgjq7aD on Solana mainnet with product status listed as Live.

Governance and Community

Marinade operates as a community DAO. Major decisions such as fee changes, new product launches, and delegation strategy updates go through on-chain governance via Realms. The protocol describes itself as community-funded from its treasury. An active research forum supports proposal development, and MNDE holders participate in shaping the protocol direction through binding on-chain votes.

Ecosystem Fit and Integrations

Marinade is integrated with major Solana wallets including Phantom, Solflare, Coinbase Wallet, and Ledger, as well as institutional custodians including BitGo, Anchorage Digital, Zodia Custody, and Copper.co. The Canary Marinade Staked Solana ETF (ticker SOLC) launched with BitGo custody, extending Marinade staking infrastructure into a regulated investment product. In April 2026, Anchorage Digital began offering Marinade automated staking strategies to institutional clients, enabling them to combine Marinade validator selection with qualified custody.

On the DeFi side, mSOL is one of the original liquid staking tokens on Solana and remains broadly supported across protocols for lending, liquidity provision, and collateral, integrated with Kamino, Orca, and Raydium among others. Marinade publishes an annual Solana Staking Report tracking the broader staking landscape; by end of 2025, approximately 415 million SOL was staked (around 75 percent of circulating supply), with unique staking wallets growing 20 percent year-over-year to 660,350.

Marinade SAM directly supports Solana validator decentralization: by distributing stake across more than 170 validators through an open bidding process, the protocol discourages stake concentration and expands the set of economically viable validators on the network. The platform has served over 150,000 token holders since its 2021 launch.
