How Fuel Earn works

Position lifecycle

1. Open: deposit approved collateral with a fresh signed O2 price quote and choose a 6, 9, or 12-month term.
2. Receive: the Vault mints one native Fuel position NFT to your wallet.
3. Hold or transfer: the NFT holder owns the collateral claim and fixed USDC return rights.
4. Sell: escrow the NFT in BondMarket at a fixed FUEL or USDC asking price.
5. Exit: claim principal plus USDC at maturity, or begin a 14-day early-unbonding period and forfeit the return.

Fixed opening economics

The Vault records the collateral, opening price, term, maturity, and promised USDC when the transaction confirms. Transfers and market sales do not reset or modify these terms.

opening value = collateral raw × signed price e6 ÷ 1e9
fixed return = opening value × 10% × term ÷ 365 days

Authority

Wallet-signed transactions change protocol state. Cloudflare Workers provide signed quotes, indexing, and read APIs but cannot open, transfer, list, buy, unbond, or claim a position for a user.

Important limitations

• The current market is fixed-price and ask-only. Escrowed bids and auctions are not implemented.
• Rewards unlock only at maturity; there are no partial reward claims.
• Managed custody means collateral can be deployed outside the Vault.
• Test assets are valueless and testnet-only.
