Frequently asked questions about SF Yield Vault

Common questions about SF Yield Vault. New to vaults? Start with Getting Started.

General

What is SF Yield Vault?

An automated yield product built on asset-specific, ERC-4626 vault contracts. You deposit an asset, receive vault shares representing proportional ownership, and earn variable yield as the vault's strategies deploy the assets. The value of your shares changes with strategy performance. See the Overview.

How is SF Yield Vault different from Fixed-Rate Lending?

The vault gives you variable yield with no maturity and fully automated management; Fixed-Rate Lending gives you a fixed rate for a defined term with direct position management. The current vault strategies actually lend into the Fixed-Rate Lending markets on your behalf — the vault is the hands-off way in. Comparison table in the Overview.

What assets can I deposit?

Each vault takes a single base asset: the JPYC Vault accepts JPYC (Ethereum), the USDFC Vault accepts USDFC (Filecoin). See Available Vaults and Strategies.

Deposits

What happens when I deposit?

Your assets transfer to the vault contract and vault shares are minted to your wallet. The vault may then allocate the assets to its strategy — funds can also sit unallocated for a time during allocation updates or liquidity management. You never interact with the strategy directly. Walkthrough: Deposit assets.

Do I need to approve tokens before depositing?

Yes. The app requests an Approve transaction before each deposit — approvals are granted for the exact amount of that deposit, so every new deposit needs its own approval. Just follow the prompt when it appears.

I deposited, but the numbers haven't changed. Is something wrong?

Probably not. If the transaction succeeded in your wallet, your deposit is on-chain. Displayed figures like TVL and APY come from an indexing service and can lag by a few minutes — refresh after a short wait. Your Holdings is read directly from the vault contract, so it typically updates first.

Withdrawals

Can I withdraw at any time?

Yes in the sense that there is no lock-up or fixed term — you can request a withdrawal whenever you like. Completion depends on strategy liquidity: if the underlying order book cannot absorb the unwind, the transaction reverts and no funds move. You can try a smaller amount, or try again once liquidity recovers — withdrawal is not guaranteed at any given moment. See Withdraw assets.

Why is the amount I receive different from what I deposited?

The on-screen figure is an estimate at the current PPS; execution uses the PPS at that exact moment, so small differences are normal timing effects. Larger differences reflect strategy performance since you deposited.

Can I withdraw only part of my position?

Yes. Redeem any portion of your shares; the rest keeps accruing yield.

Shares and yield

Why doesn't my share balance change?

By design. Yield appears in the value of each share, not the share count — your balance moves only when you deposit or withdraw. Because gains fold into the share price, yield also compounds automatically.

How many shares do I receive when I deposit?

Your deposit amount divided by the price per share (PPS) at execution: $\text{Shares minted} = \text{Amount} \div PPS$

How much do I get back when I withdraw?

Your redeemed shares multiplied by the PPS at execution: $\text{Assets returned} = \text{Shares} \times PPS$ — more than you deposited if yield has accrued, less if the strategy has taken losses.

How is the price per share (PPS) calculated?

Total assets divided by total shares: $PPS = \text{Total Assets (idle + reported strategy balances)} \div \text{Total Supply of Vault Shares}$

Strategy and allocation

Can I choose or change the strategy?

No. Strategy selection and allocation are part of the vault's configuration — you interact only with the vault. What each strategy does is documented in Available Vaults and Strategies.

Why does the app show "Unallocated" assets?

Assets temporarily not deployed to a strategy — normal during allocation updates or liquidity management, and no action is needed from you.

Fees

Are there any fees?

No deposit, withdrawal, or management fees. The strategies charge a 5% performance fee on realized profits, deducted before gains reach the vault — the price per share is always net of fees. Details in Fees; current values also appear in the app's About tab.

Risks

Is my deposit guaranteed?

No. Vault positions carry smart contract, strategy, liquidity, and market risk — the value of your position can decrease if the strategy takes losses or conditions turn. Withdrawals are not guaranteed at all times either: they depend on order-book liquidity. Each strategy's page lists its specific risks — JPYC, USDFC — and the protocol-wide Risk Disclaimer applies.

Technical

Do vaults custody my assets?

Vaults are non-custodial smart contracts. You interact with them directly from your wallet, and every transaction requires your signature. Addresses are listed in Contracts and Security.
