Kintsu

About

Kintsu is a composable liquid staking protocol built on Monad (and Hyperliquid) that issues reward-bearing Liquid Staking Tokens (sMON, sHYPE) backed by staked native gas tokens. It pools user deposits, delegates them across a DAO-governed validator registry, and returns both staking consensus rewards and MEV yield to the pool — while the sTokens remain fungible and usable across DeFi (lending, DEXes, farming, perps, restaking, and more). The protocol also offers superMON, a curated on-chain vault that combines base staking yield with additional DeFi trading strategies managed by professional high-frequency traders and risk managers.

Where Does Yield Come From?

Kintsu generates yield from two sources built into the blockchain network itself:

  1. Staking rewards — the network creates new tokens and gives them to validators who help secure it.
  2. MEV fees — extra profits that validators can capture by ordering transactions cleverly.

How it works

Users deposit native gas tokens (MON on Monad, HYPE on Hyperliquid) into Kintsu's Vault. In return, they receive liquid staking tokens called sMON or sHYPE (sTokens for short). These sTokens are "reward-bearing" — they grow in value over time, not in number.

Kintsu pools everyone's deposits together and delegates them across a group of validators. Which validators get how much stake is decided by the Kintsu DAO (governed by holders of the KSU token) through an on-chain Validator Registry. Validators compete for larger delegation by producing better yields. They are required by Kintsu's smart contracts to send all staking rewards and MEV fees back to the Vault. Blockchain slashing (penalties for misbehavior) helps enforce this.

Automatic compounding

Kintsu automatically takes the returned rewards and re-delegates them as additional stake, so your yield compounds without you needing to do anything.

How sTokens increase in value

sTokens are non-rebasing — their total supply stays fixed. Instead, the ratio of pooled MON to outstanding sMON (the "redemption ratio") rises over time. When you unstake your sMON, you receive more MON than you originally deposited. So your yield shows up as a better redemption rate, not as more tokens in your wallet.

Protocol fees

Kintsu charges protocol fees, though the exact split is not detailed on the pages reviewed.

superMON — the curated vault

Beyond basic staking, superMON is a separate vault that takes the staking yield and adds extra DeFi strategies on top. These strategies (lending, pooling, trading) are managed by professional high-frequency traders and risk managers, aiming for higher returns than network staking alone.

Composable yield with sTokens

Because sTokens are fungible and non-rebasing, they work like normal tokens across DeFi. You can use them as collateral in lending markets, provide them as liquidity on DEXes, put them into farming pools, trade perpetual futures with them, or restake them. This means you can earn two yields at once — the underlying staking yield from the blockchain plus whatever yield you get from your DeFi activity.

Audits

Audit / DateFindingsVerdict
  • Critical0
  • High3
  • Medium3
  • Low2
  • Info3
The audit uncovered several high-severity accounting and fee logic flaws, all of which were fixed and verified before publication, meaning the protocol's core staking mechanics are materially more robust. The residual informational items are unlikely to pose a safety risk but serve as useful design notes for ongoing development.

All 7 findings were remediated and verified, including the critical share-price manipulation and high-risk locked-asset bugs, so the audited commit presents a materially secure codebase; the removal of instantUnlock and syncStaking also simplified the attack surface.

This audit found zero security vulnerabilities across all standard severity bands; only three Best Practices items were identified and all were fixed, reflecting a well-engineered codebase with sound architectural design for the Monad liquid staking protocol.

  • Info0
Nethermind's audit of Kintsu found zero security vulnerabilities across all severity bands (Critical, High, Medium, Low, Informational), with only three Best Practices issues that the Kintsu team promptly fixed. The protocol's design for liquid staking on Monad demonstrates sound security posture for mainnet deployment.
