Pretty cool to see Cyclical Rates finally go live.
I came up with the original mechanism during my time at Euler as a way to bridge the gap between variable-rate lending and fixed-term credit.
Instead of fixed maturities, Cyclical Rates use recurring repayment windows that repeat forever. Borrowers get a predictable rate for most of the cycle, but face sharply higher rates during the repayment window, creating a strong incentive to refinance or repay.
The result is a perpetual fixed-rate lending market: borrowers get rate certainty, lenders get structured liquidity events, and positions remain fungible and composable onchain.
As far as I'm aware, there isn't really a traditional finance analogue. It's a genuinely crypto-native lending primitive that only works because smart contracts can coordinate these recurring incentive cycles automatically.
Very cool to see the team take it from concept to production.
1/ Predictable pricing is what lets capital lend and borrow at scale. Onchain ETH credit has rarely had it.
KPK ETH Yield Term, live on
@eulerfinance, brings a fixed, benchmark-set rate to ETH lending.
