Yield, safety, liquidity. Every DeFi product makes you pick two. Royco Day, is a serious attempt at all three at once. Here's how it works👇 First, the core idea: Risk tranching = Splitting a pool of yield-bearing assets into layers that absorb losses in a fixed order. - Junior layer eats losses first and earns extra yield for standing in front. - Senior layer sits behind and gives a slice of its yield to pay for it, and only takes a hit once junior is fully wiped out. Same pool, two risk profiles: total risk stays the same, it just gets moved onto the party being paid to hold it. ( just like the PRJX pools i shared on a post earlier today) So why does DeFi need this? 1. Tranching lets 2 types of investors hold the same pool at different risk levels. ( gambler + investor ) 2. in 2008 senior bondholders learned their buffer was too thin only after it was gone. - > Royco Dawn enforces the loss waterfall by smart contract and publishes every market's coverage ratio on-chain, so you can watch the buffer in real time. Royco Dawn solved protection, but it did nothing for liquidity: a protected position in an RWA strategy that settles T+7 or T+30 still waits that long to exit. Safely stuck capital... Day is the fix. It adds a third tranche, the SLP: an AMM pool pairing Senior Shares with a stablecoin. Senior holders who want out swap through the pool instantly instead of joining the redemption queue, and Senior pays the SLP a liquidity premium out of its yield, the same way it pays Junior for first-loss cover. Protection and liquidity become two separate dials an issuer can configure, both contract-enforced. @roycoprotocol has been in the @xerberus register for a while (rated A+ as of our July evaluation), but this was the first time I personally went this deep into risk tranching and what Dawn and Day actually do. One thing I'll be watching as Day goes live: SLP depth. Instant exit holds up to the size of the pool. In a crowded exit the queue converts into slippage, and once Senior Shares get looped as collateral, that single liquidity assumption carries the whole stack. A must read for anyone allocating to on-chain yield 👇
