Sapien Vault

Summary

Ketju does not approve Sapien Vault because its $77,000 in deposits is below the size limit for a full review. The live yield feed showed one SAPIEN vault on Base with about $77,000 deposited. Nearly all of the displayed rate came from SAPIEN rewards instead of underlying cash flow. We have made no finding against Sapien Vault. At this size, we lack evidence that a client could deposit and withdraw a position of the proposed size.

Review triggers
• A wallet-level test demonstrates the deposit, unlock and withdrawal that a contemplated position would need
• Sapien publishes current contracts, privileged roles, audits, reward funding and evidence of unlocks and withdrawals under stress, and Ketju reviews them

Ketju checks this memo every night and opens a review if its venues or files show a warning or a cited document changes. The first confirmation is due 2026-11-26.

Research

How it works

Sapien’s live collateral app accepts SAPIEN deposits, ages each position, and allows withdrawal after its lock ends. The holder therefore keeps exposure to the volatile SAPIEN token while it is locked, and the receipt is no dollar loan or savings claim. The live yield feed showed one SAPIEN vault on Base with about $77,000 deposited. Nearly all of the displayed rate came from SAPIEN rewards instead of underlying cash flow. We keep enough evidence here to show that Sapien Vault falls under the size limit for a full review. This memo is not a full review of Sapien Vault.

Who controls it

The official page identifies the live Base vault and its lock cycle. It does not publish enough about the operator, reward funding, audits or loss history to support a full review. These controls and its incident history may change Sapien Vault’s operating risk, but they do not change its size. We do not treat a clean history as proof of safety. A young deployment may have faced few attacks, and an established one can work as designed, with no exploit, and still not suit a client account.

Withdrawals

A holder must wait for the position to unlock before withdrawing. The pool’s reported $77,000 shows its accounting size, but it does not show what a given wallet can withdraw at unlock. Total TVL is an accounting figure. It does not show that a given client position can be withdrawn at the displayed value. Ketju will apply the size limit until one of the review triggers below occurs and a new review measures a withdrawal at the proposed size, instead of inferring it from a dashboard total.

Comparison

Holding a reviewed asset directly avoids the extra vault and lock. A mature staking product would need independent review of its reward mechanics, its privileged roles, its audits and how much holders can withdraw. We compare what the client would hold, and brand or headline rate plays no part. Ketju publishes one size limit instead of repeating the same judgment in slightly different words for every venue. The protocol sources below let a reader reproduce the classification and check the review triggers.

Size limit

Ketju does not approve Sapien Vault because its deposits are below the size limit for a full review. Size makes no finding about quality. Reported TVL measures how much the protocol holds. It does not show what a client would own, who can change the rules, or whether a position can be sold or redeemed at size. Ketju will review the protocol in full when its deposits pass the size limit.

Sources

Each claim above comes from one of these sources. Where Ketju could not verify a number, the memo states that.

The asset and the chain

This memo covers the protocol. A position also holds an asset and settles on a chain. Whichever of the three holds the most power over the position decides who can freeze it. These tables describe control and do not judge quality.
