Open a position

Choose collateral

Fuel Earn accepts only the configured FUEL and stFUEL assets. Deposit eligibility is based on the selected asset's current wallet balance. Amounts use exact nine-decimal conversion; the slider and 25%, 50%, and Max presets never exceed that balance.

Review the estimate

The interface reads the live O2 bid and simplified rolling TWAP directly from Fuel RPC, then displays the lower value and retained sample count. Estimates are informational; the Vault validates both prices itself when the transaction executes.

Confirm the deposit

When you select Deposit, the wallet submits the collateral and selected term. The Vault selects the lower validated 1e18 bid and floors it once to e6. Any genuine rolling sample count is accepted, but a stale, unavailable, malformed, or zero value from either oracle fails closed.

Confirmation

After finality, the success receipt shows:

• collateral committed
• selected term
• exact conservative on-chain opening price
• fixed USDC return
• expected maturity
• transaction link

The app then opens My positions, where the newly minted position NFT is read directly from your wallet.
