Term Finance is a fixed-rate on-chain lending protocol built on Ethereum that uses a sealed-bid auction mechanism — called the Term Auction — to clear market-determined fixed interest rates for short-duration loans (typically 1 week, 4 weeks, and 12-week maturities). Unlike variable-rate protocols such as Aave or Compound (where rates fluctuate algorithmically in real time based on supply/demand), Term Finance’s rate is set once at auction clearing and remains fixed for the entire loan duration — both the borrower and the lender know their exact rate at the moment the auction settles. The auction process: during a 24-hour bidding window, borrowers submit sealed bids specifying how much they want to borrow and the maximum rate they’ll accept; lenders submit offers specifying how much USDC they’ll supply and the minimum rate they require. After the bidding window closes, Term Finance’s algorithm solves for the clearing rate — the single rate at which the maximum supply-demand overlap occurs — and all matched borrowers/lenders transact at that clearing rate. This creates genuine on-chain yield curve discovery: the 1-week rate, 1-month rate, and 3-month rate emerge from market participants’ actual demand and supply at each maturity. TERM is the protocol’s governance token. Term Finance targets institutional defi users: crypto-native trading firms that need fixed financing costs for specific strategies, DAO treasuries managing yield, and sophisticated LPs who want to lock in fixed yields without exposure to rate model fluctuations.
Key Facts
- Protocol: Term Finance
- Network: Ethereum (Mainnet)
- Mechanism: Sealed-bid auction (clearing price = fixed rate for all matched parties)
- Loan maturities: ~1 week, 4 weeks, 12 weeks
- Governance token: TERM
- Target users: Institutional DeFi, DAO treasuries, sophisticated LPs
- Differentiation: Only major protocol using auction-based rate discovery for fixed-rate DeFi
How the Term Auction Works
- Auction opens: Borrowers and lenders submit sealed bids (not visible to others)
- Bidding window (~24 hours): Participants submit their rates and amounts
- Clearing: Algorithm finds clearing rate (max matched supply/demand)
- Settlement: All matched borrowers/lenders locked in at clearing rate
- Loan duration: Fixed until maturity (e.g., 28 days)
- Repayment: Borrowers repay principal + fixed interest at maturity
Sealed-bid advantage: Participants cannot see others’ bids → strategic behavior limited → rates closer to true market equilibrium
Fixed-Rate vs. Variable-Rate Lending
| Feature | Aave (Variable) | Term Finance (Fixed) |
|---|---|---|
| Rate | Changes every block | Fixed at auction |
| Rate risk | Borrow rate can spike overnight | Known in advance |
| Use case | Short-term, flexible borrowing | Specific-duration financing |
| Exit flexibility | Repay any time | Must repay at maturity |
| Rate discovery | Algorithmic (utilization model) | Market auction |
| Yield curve | No | Yes (1w, 4w, 12w) |
Collateral and Risk
- Accepted collateral: Primarily blue-chip assets (USDC, ETH, wstETH, wBTC, stETH)
- Liquidation: If collateral falls below maintenance ratio before maturity → liquidated
- Smart contract risk: Immutable core with audited contracts
- Rollover: Borrowers can roll to new auctions at term end
