DeFi spent its first cycle proving that variable-rate, overcollateralized lending works for crypto. It also proved why institutions stayed away: you cannot run a credit business when the cost of capital is repriced every block.
Institutions need predictable cost of capital
Every TradFi credit instrument, whether a term loan, a bond, or commercial paper, fixes a rate for a defined period. That is not a preference; it is how balance sheets are managed. A treasurer financing working capital has to know the cost for the life of the facility. Variable-rate debt that floats with pool utilization is not underwritable at scale.
Make it concrete. A fund holding tokenized Treasuries needs short-term working capital and weighs borrowing against them rather than selling. At a fixed rate locked for 30 days it knows the cost to the dollar and can judge whether the trade clears. At a floating rate that might read 6% today and 14% after a utilization spike, it cannot, so the deal happens off-chain or not at all. Fixing the rate is what moves that capital onchain.
Tokenization solved the collateral, not the credit
The last two years tokenized the assets, from tokenized Treasuries and money-market funds to onchain private credit, but mostly wrapped them as yield tokens. Holding a tokenized Treasury is not a credit market. The missing piece was a place to lend against those assets at terms institutions recognize.
The market is converging on fixed-term credit
This is not a contrarian bet. Fixed-rate, term-based credit is the structure all of traditional finance runs on, and onchain lending is moving the same way: Morpho is building out fixed-rate, fixed-term markets, explicitly to win the institutional credit that will not touch variable-rate debt at scale. What the existing efforts do not pair it with is permissionless lending against tokenized real-world-asset collateral, and that is the lane Splyce is built for. For the mechanics, see fixed-rate RWA lending and fixed-rate vs variable-rate lending.
Splyce's bet
Single Asset Vaults isolate one borrower and one collateral type, lock the rate at deposit, and settle at maturity. They are overcollateralized, by default KYC'd on the borrower side, governed by Master Loan Agreements, and for RWA collateral run oracle-free by default, with no price feed forcing a mid-term liquidation. splyceUSDC makes that same fixed-rate credit liquid for anyone with a wallet, earning a blended rate across the vault book.
Variable rates made DeFi liquid. Fixed rates make it bankable. Tokenized real-world assets are the collateral that lets onchain credit finally meet institutions where they are.
