I have, for the most part, been avoiding @RobinhoodCrypto chain. That said, two of the three existing @Morpho markets are pretty interesting for trusted stablecoin loops. 1) USDe (@ethena) • 4.5% Collateral Yield • 3.63% Borrow Cost • $12M to Borrow ➢ 15% Net APR at 10x 2) syrupUSDG (@maplefinanc

@defi_dadJul 2026

Can we get 100 people to say “Monad”?
