FxAeon is an independent interface for f(x) Protocol. Use the web app or Telegram Mini App to trade ETH and BTC, save with fxSAVE, borrow fxUSD, and bridge supported assets. Your selected wallet confirms each transaction.
Choose the right network
The asset’s name is not enough to identify where it can be used. Check its network before funding an action.
| Action | Network | What you use |
|---|---|---|
| Trade | Ethereum | ETH or BTC long and short positions, with the input assets offered by the form. |
| Earn | Ethereum | fxSAVE deposits, withdrawals, and claims. Deposit assets include fxUSD, USDC, and fxSP. |
| Borrow | Ethereum | ETH or BTC collateral positions with fxUSD debt. |
| Move | Ethereum ↔ Base | fxUSD and fxSAVE, with ETH on the source network for fees. |
Bridging fxSAVE to Base does not move the Earn vault or make the Ethereum Earn form available on Base. Move it back to Ethereum to use that form.
Understand the assets
- fxUSD is the protocol’s USD-pegged asset. Its market value can differ from one dollar.
- fxSP is a Stability Pool share. It is distinct from fxUSD and fxSAVE.
- fxSAVE is an ERC-4626 vault share that compounds Stability Pool rewards. A share balance and its underlying asset value are different quantities.
The protocol’s Stability Pool documentation (opens in a new tab) explains the underlying pool and vault. The glossary explains the names used in FxAeon.
