Our verdict on Typus Safu
4.5/10Typus Safu suits only existing holders who need to redeem, as the vaults are closed to new deposits. Its idea of lending yield with options upside and a 99.99% protection target was interesting, and redemption stays free of exit fees. The caveats are the reported October hack on Typus, no listed audits on DefiLlama, small TVL, and a protection claim that is hard to verify. Anyone considering other Typus products should read the docs and incident report first.

What is Typus Safu?
Typus Safu is the Secure Asset Fund for Upside, a yield product from Typus Finance on the Sui blockchain. It combined base yield from lending protocols with potential upside from options, and was described as offering 99.99% protection.
The homepage now says SAFU vaults are closed. Existing positions stay redeemable at any time with no exit fee. Typus currently promotes its relaunched perpetuals, the Typus Liquidity Pool (TLP), options bidding and options vaults instead.
DefiLlama lists Safu with roughly $128,000 in TVL and no audits, and it has been tracked since September 2024. Public reporting also point to a hack on Typus Finance in October, with perpetuals paused afterwards. Anyone with exposure should read the official incident report and terms.
How Typus Safu works
Typus Safu was built as a structured yield vault. Deposited assets earned base yield by being lent out through established lending protocols. Part of that yield funded options positions, which could add upside if the market moved in the right direction. The aim, as stated, was 99.99% protection with options-driven extra return.
Typus options are cash-settled. Call options settle in tokens such as SUI, and put options generally settle in stablecoins such as USDC. Vaults ran in cycles. When a vault entered auction, deposits moved into a lockup period and could not be withdrawn until the cycle ended.
The homepage now states that SAFU vaults are closed. No new deposits are taken, but users who still hold positions can redeem them at any time without an exit fee.

Pros and cons
What we like
- Existing positions can be redeemed at any time with no exit fee, according to the homepage
- The structure paired lending yield with options upside rather than relying on a single source
- Options settlement rules are documented, including which assets settle calls and puts
- Typus runs on Sui and has a broader product set around Safu
- Redemption stays open even though new deposits are closed
Watch out for
- SAFU vaults are closed to new deposits, so the product can no longer be used for fresh yield
- Typus suffered a reported hack on the Sui blockchain in October, after which perpetuals were paused
- DefiLlama lists no audits for this product, and the homepage does not name auditors in the text available
- TVL is small, about $128,000, which limits depth and reflects low usage
- The 99.99% protection claim is a marketing figure; the sources reviewed do not explain how it is backed
- Options carry risk of losing the premium, and the project's own vault terms warn users to review risks
Typus Safu fees
Typus does not publish a Safu fee schedule in the material reviewed. The homepage says there is no exit fee on redeeming existing SAFU positions.
Vault products of this type usually take performance or management fees, and options premiums affect returns. Users should check the vault terms in the app and docs. Sui network gas fees also apply to transactions.
Is Typus Safu safe?
DefiLlama lists no audits for Typus Safu. The homepage has an "audited by" section, but the auditors are not named in the text available, so readers should check the docs.
Public reporting report a hacker attack on Typus Finance on the Sui blockchain on October 16, with an incident report from the team. Another result says collateral on paused perpetuals was safe and liquidation halted after an internal vulnerability was fixed. The 99.99% protection figure is a project claim and not a guarantee. Options vaults carry smart-contract, counterparty and market risk, and the Safu product is closed to new deposits.
