Constant Finance says fixed-rate DeFi lending still misses one key thing: time

Constant Finance argues that fixed-rate lending in DeFi does not fully solve borrower and lender matching on its own, because most markets still organize liquidity around maturity dates rather than actual usage periods. In a long-form post by Stephen, the project says current fixed-rate structures can lock an advertised rate but still leave a borrower’s final cost uncertain if the position needs to be closed early. That uncertainty can come from paying for a longer term than needed or from having to unwind through a secondary market at whatever price the market offers at the time. The article traces the development of fixed-rate lending from Yield Protocol and Notional Finance in 2020 to Term Labs’ inclusion in a16z CSX in 2024 and Morpho’s launch of Midnight alongside Blue. It contrasts those efforts with floating-rate markets such as Maker, Aave and Venus, where borrowing costs can rise during a strategy’s life. Using BNB Launchpool as an example, it says a borrower may enter at 2% APY only to see costs rise to 6% or 7% once demand jumps. Constant Finance says its own design pairs fixed rates with agreed early repayment rules, allowing borrowers to pay interest only for actual days used while enabling repaid lender capital to be automatically rematched if the original lending order remains valid and suitable demand exists.

Multicoin says DeFi 1.0 tools were built for volatile crypto, not tokenized traditional assets

Multicoin Capital argues that the core machinery of DeFi 1.0 was designed around the traits of native crypto assets such as BTC, ETH, SOL and HYPE: high volatility, heavy speculation, long-tail token supply and permissionless access. In that setting, automated market makers, perpetual futures, overcollateralized lending and floating-rate pools made sense, even if they looked inefficient through a traditional finance lens. The firm’s latest market structure essay says that logic breaks down as tokenized U.S. Treasuries, equities, corporate credit, commodities and FX move on-chain in greater size. The paper lays out what it calls a DeFi 2.0 stack. For lower-volatility assets with tighter spreads, defined maturities, predictable cash flows, stronger collateral and more identifiable borrowers, Multicoin sees central limit order books, RFQ systems, propAMMs, fixed-rate lending, rate derivatives, options, repos, dark pools, dated futures and portfolio margin becoming much more important. It also argues that value capture will not be limited to one layer. Blockchains, core protocols, aggregation and prime-brokerage functions, and customer-facing applications that control order flow could all benefit if RWA activity expands on-chain. In Multicoin’s view, the next phase after tokenization is making those assets actually useful once they are on-chain.

Why fixed-rate crypto lending struggles: maturity mismatch, not just pricing

A Foresight article by Stephen argues that weak activity in fixed-rate lending does not necessarily mean borrowers lack demand. The bigger issue, the piece says, is that many existing products fail to handle maturity mismatch between a loan’s contractual term and the borrower’s actual funding window. If a borrower can only repay at par or exit at market price, the contract does not automatically allow settlement based on the original fixed rate for only the time the capital was actually used. The article uses a simple example: a borrower receives 100,000 USDC and owes 100,600 USDC after 30 days. If the strategy ends on day 7, repaying at face value still requires the full 100,600 USDC, even though interest for seven days would be only 140 USDC under the same simple-interest assumption. The remaining 460 USDC becomes the cost of unused time. Stephen also argues that adding more pools or quoted markets does not by itself solve fragmentation if matching still requires the same asset, amount, and maturity. The piece says Constant Finance, now live on testnet, is built around fixed-term loans, prepayment based on actual borrowing time, and an embedded refinancing mechanism. In that framework, the meaningful comparison is not the headline rate alone, but the borrower’s total financing cost over the period the funds are actually used.

Castle Labs maps three ways fixed-rate crypto lending is trying to solve its liquidity problem

Castle Labs argues that DeFi lending has already solved one major problem for borrowers: near-instant access to collateralized credit. What it has not solved is cost certainty. In a market with $28.5 billion in active loans, almost all demand still sits in floating-rate products, leaving borrowers exposed to sharp rate changes when utilization spikes. The report says demand for fixed-rate, fixed-term credit is rising among funds, treasuries, RWA issuers, basis and arbitrage desks, revolving borrowers, leveraged yield users, traders, market makers, and capital allocators. The challenge is structural. Earlier fixed-rate protocols struggled with fragmented liquidity across maturities and collateral types, weak exit paths for lenders before maturity, and a cold-start problem when capital had to sit idle while waiting for a match. Castle Labs reviews three newer designs from Morpho Midnight, Jupiter Offerbook, and Kamino. Together, the three protocols account for $6.83 billion in active loans on the floating-rate side and have started pushing into fixed-term lending. Their approaches differ, but each tries to reduce idle capital, improve exit flexibility, and make fixed borrowing easier to access through existing distribution channels and infrastructure.

Morpho Midnight targets fixed-rate lending’s cold-start problem with intent-based matching and tradable positions

A research excerpt published by Castle Labs examines why fixed-rate, fixed-term lending is drawing renewed attention in DeFi and how Morpho’s newly launched Midnight protocol is trying to solve one of the sector’s hardest structural issues: the cold-start problem. With roughly $28.5 billion in active onchain loans still concentrated in floating-rate markets, borrowers can access credit quickly, but their financing costs can swing sharply when utilization spikes. The report argues that this uncertainty has become more problematic as DeFi lending expands into institutional treasury use, basis trading, looping strategies, and tokenized real-world asset structures. According to the article, Morpho Midnight, launched in July, uses an intent-based model in which lenders and borrowers post quotes without locking funds upfront. Capital is only called when a match is settled, allowing the same liquidity to be quoted across multiple markets and reducing idle capital. The piece also highlights Midnight’s tradable credit and debt units, which are meant to improve pre-maturity exits. Castle Labs compares that design with two other fixed-term lending efforts now entering the market: Jupiter Offerbook, which supports 1- to 30-day loans and transfers collateral at maturity instead of using price-based liquidation, and Kamino’s planned fixed-rate reserve grid embedded inside Kamino Lend. Together, the report says, the shift shows fixed-rate lending moving from a niche design problem toward a broader infrastructure race inside DeFi credit.

Term Labs Recovers All Fixed-Rate Loan Positions, Details Attack Vector

Term Labs, a fixed-rate lending protocol, announced that all fixed-rate loan positions in affected vaults have been recovered as of August 25. The incident was limited to the floating balance in Term vaults; meta-vaults and related strategies remain closed. The attacker funded via Tornado Cash, submitted a governance proposal to zero out the governance delay, deployed fake contracts, and drained funds. Term V1 and V2 contracts were not compromised, and the direct lending market continues to operate normally.

TermMax secures strategic investment from YZi Labs, with total funding above $8 million

Fixed-rate lending protocol TermMax has announced a strategic investment from YZi Labs, though the size of the deal was not disclosed. The protocol, developed under parent company Term Structure Labs, was also selected for Season 3 of YZi Labs’ EASY Residency incubation program. TermMax said it has raised more than $8 million to date, with previous backers including Cumberland DRW, which led its 2023 seed round, alongside HashKey Capital, Decima Fund, Longling Capital and MZ Web3 Fund. Since launching its mainnet in April 2025, the protocol has expanded to 10 EVM-compatible chains and now runs 60 fixed-rate markets and 40 strategy vaults. It reports total value locked in the tens of millions of dollars and more than 1.5 million registered wallets. TermMax structures fixed-rate lending by splitting debt into three tradable tokens: FT, described as zero-coupon bonds; XT, representing interest and option value; and GT, representing leveraged position certificates. Liquidation is handled through physical settlement. Its token, TMX, completed its token generation event on Aug. 25 and began trading the same day on Binance Alpha, Kraken, Bitget, MEXC and KuCoin. The team said its next focus areas include on-chain yield curves, rate and options markets for tokenized equities, and an institutional financing platform called TermPrime.
