Earn deposits into fxSAVE and manages withdrawals on Ethereum. fxSAVE is a vault share, so the number of shares you hold and the assets they represent are separate values. Its APY is variable.
Before you start
Use the wallet that owns your assets and keep ETH on Ethereum for fees. Deposits support fxUSD, USDC, and fxSP. Withdrawals spend fxSAVE shares, not the displayed USD estimate of those shares.
Deposit into fxSAVE
- Select Deposit and choose fxUSD, USDC, or fxSP in the asset picker.
- Enter an amount within the selected wallet’s available balance.
- Open Review deposit. Check the input, estimated fxSAVE output where available, fees, and the route’s actual minimum.
- Confirm any token approval, then the deposit. After confirmation, inspect the receipt and refreshed fxSAVE balance.
Understand the deposit minimum
For routed fxUSD and USDC deposits, the pinned SDK supplies a fixed floor checked in fxSP base-pool-share units. It is not a separately enforced final fxSAVE minimum, and changing a slippage preference does not set a custom deposit tolerance. A direct fxSP deposit has no routed minimum-output floor.
The review keeps an estimated fxSAVE output separate from a minimum expressed in fxSP. Read the units rather than treating those figures as interchangeable. The deposit method reference explains the integration limitation.
Choose a withdrawal route
Select Withdraw, enter the fxSAVE shares to redeem, and choose the receive asset or withdrawal route.
| Route | Result | What to check |
|---|---|---|
| Instant | Redeem into the selected fxUSD or USDC receive asset without a cooldown. | The instant-exit fee and conversion minimums. Max slippage changes the applicable conversion limit, not the fee. |
| After cooldown | Request a withdrawal, then submit a separate claim for fxUSD and USDC when ready. | The current cooldown and claim status. Network fees apply to both request and claim. |
| Direct to fxSP | Redeem fxSAVE directly into Stability Pool shares. | This is an fxSP payout, not fxUSD or USDC. It has no queued claim or cooldown; network fees still apply. |
The form reads the current instant-exit fee and cooldown. Check the actual review rather than assuming an old rate or waiting period. The protocol’s redemption documentation (opens in a new tab) describes the underlying withdrawal methods.
Claim a queued withdrawal
A confirmed request queues a redemption; it does not pay out immediately. Earn and Portfolio expose its claim status. When a fresh read says it is ready, open the claim, review it, and confirm the separate transaction. The pending quantity is recorded in fxSP; payout previews are estimates of fxUSD and USDC, not fixed final amounts.
Understand the return and result
The vault compounds Stability Pool rewards. A quoted APY is an annualized display rate, not a guaranteed return or your earnings to date. Read the Stability Pool and fxSAVE explanation (opens in a new tab) and risk guide before depositing.
Wait for the confirmed receipt and a refreshed balance or claim status. If a read fails, retry the read; if an action submitted, check History before sending another request. fxSAVE held on Base must return to Ethereum to use Earn here.
