Typus DOV Review 2026: Sui Options Vaults in Transition

Typus DOV is the DeFi Options Vault line of Typus Finance, a derivatives protocol on the Sui blockchain. It was listed in May 2023 and lets users deposit assets into automated options strategies, or buy short-dated options with high leverage.

The product has changed. The homepage now leads with a perps relaunch and the Typus Liquidity Pool, while the SAFU vaults are closed and a search result says Typus V1 is being sunset. The homepage still links to options vaults, described as a place to review current terms and risks or manage an existing position.

On-chain value locked is about $926,000, with a small weekly change. That is modest, so users should treat Typus as a niche, higher-risk venue. The protocol has its own TYPUS token.

An options vault pools user deposits and runs a fixed strategy, such as selling covered calls or cash-secured puts, or a call spread. The vault sells options to traders and collects the premium. That premium is the yield for depositors, and it can be offset by losses if the market moves against the strategy.

On the other side, traders buy options with short expiries, from 10 minutes up to a month. Because the buyer's maximum loss is the premium, Typus says positions carry no liquidation risk even at very high leverage. A buyer can still lose the entire premium if the option expires out of the money.

Typus has since added a perpetuals exchange and the Typus Liquidity Pool (TLP), which supplies liquidity for trading. The V1 products are being sunset, and the older SAFU vaults are closed but redeemable.

Typus does not publish a detailed fee schedule in the material reviewed. The homepage describes fees as low for perps, and states that redemption from the closed SAFU vaults carries no exit fee.

Option premiums, perp trading fees, vault performance fees and Sui network gas costs would appear in the app before a user confirms a transaction. Check these on the vault or trading screen, and read the terms linked on the site.

Typus lists two audits, and the homepage has Audited By and Backed By sections, but the audit firms are not named. Like all DeFi derivatives, it carries smart-contract, oracle and market risk, and vault depositors can lose principal if a strategy performs badly. Users keep custody through their own wallet, so wallet security is the user's responsibility.

The V1 sunset and closed SAFU vaults mean users with older positions should redeem them rather than leave funds idle. No licence or regulatory status is published in the material reviewed. Check that derivatives trading is permitted where you live. High-leverage products are risky and unsuitable for money you cannot afford to lose.

Typus is aimed at traders already comfortable with options, perpetuals and Sui wallets who want short-dated, high-leverage exposure or option-premium yield. It is a poor fit for newcomers looking for simple, low-risk passive income, and for holders of old V1 positions who should focus on redeeming them.
