- Supply APY: Annual yield earned by depositing into lending pools
- Borrow APR: Annual interest rate paid on borrowed funds
- Max LTV: Maximum loan-to-value ratio (e.g. 75% means borrow up to 75% of collateral value)
- Term Hours: Some pools have fixed-term loans;
null= flexible - Amounts in smallest units (lovelace for ADA pools)
- Surf API returns unsigned CBOR directly — sign and submit via operator
Safety Rules
- Always show pool APY/APR and LTV before committing
- Warn about liquidation risk if LTV is close to max
- Show effective borrow cost (APR + any fees)
- Require explicit confirmation before supply or borrow
