A variable-rate lending market that also sells fixed terms: each 4-week maturity is its own pool, the depositor's interest is stamped into contract storage at deposit, and exit before maturity is priced by a published discount formula the protocol will quote you on-chain before you sign — but on 28 September 2026 its Optimism USDC fixed-deposit book was 140,787 USDC, only 58,622.83 of it not yet matured, in an $11.38m protocol, and on Base, where the growth is, it is exactly zero. Strongest on what happens at maturity (9/10): Exactly's Deposits guide says matured deposits can be withdrawn with "no limit to the time" but earn no further interest, and nothing rolls automatically; on Optimism 80,150 USDC sits idle in the pool that matured 24 September 2026. Weakest on is the rate actually fixed, and who can change it (4/10): Exactly sets each fixed deposit's rate from its pool, and its markets are upgradeable through a 24-hour TimelockController run by a 3-of-6 Safe, disclosed on the access-control page rather than the deposit guide. Base holds no fixed deposits at any maturity. Published price: Parameters page (https://
Fixed-Rate Yield
Fixed-Rate Yield evaluated across what happens at maturity; whether the rate is actually fixed, and who can change it; the price of leaving early; and who owes you the fixed leg if the strategy misses.
Ranked here: protocols that sell a depositor a known rate to a known maturity, through principal tokens, fixed-term lending with an expiry, or a tokenised fixed leg. Not ranked here: lending and borrowing markets with no expiry, yield aggregators, tokenised T-bills and money-market funds, which the scope excludes by construction.

What matters most before choosing in this category
A fixed rate is a promise with a date attached, so the first question is not how large the rate is — it is what happens when it ends. That carries the most weight here because the published answers diverge completely: some venues state, with a worked formula, that a matured position simply stops accruing and can be claimed with no deadline; on others nothing published tells a holder what happens if they hold past maturity and do nothing at all. Then ask whether the rate is genuinely fixed or merely quoted, because on at least one venue the protocol fee is an on-chain parameter an admin can change, with no numeric rate published anywhere in its documentation and an on-chain ceiling of one hundred percent. Then price the exit, since the whole point of a term is that leaving early costs something — and this category has consolidated so hard that depth is scarce: the leader's TVL fell roughly 86% in twelve months and is still, by a wide margin, the only venue deep enough to sell into. Read the mechanism and the order book separately, because a clean redemption invariant with nobody on the other side is a rate you can enter and cannot leave.
