Royco Dawn is a non-custodial risk-tranching protocol. It takes a given yield source: a lending market, a staking deposit, or tokenized RWA, and splits it into two risk tranches:

• Senior: earns yield with smart-contract-enforced downside coverage. A defined amount of Junior capital absorbs losses before Senior is ever impacted.
• Junior: earns higher yield by serving as first-loss capital and receiving a risk premium paid by Senior in return.

​

The Yield Distribution Model

Yield distribution between tranches works similarly to lending markets. In Morpho or Aave, high utilization pushes supply rates up to attract lenders, and vice versa. Dawn utilizes a similar mechanism, with a different definition of utilization. In Dawn, utilization measures how much Junior capital is currently backing Senior exposure. If the market needs $1 of Junior coverage and there is exactly $1 of Junior, utilization is 100%. If there is $2 of Junior, it is 50%. When Junior is scarce, more yield flows to Junior to attract more first-loss capital. When Junior is abundant, more yield flows to Senior. The pool rebalances toward equilibrium based on where each side wants to deploy. For example, if the market needs $1 of Junior coverage and there is exactly $1 of Junior, utilization is 100%. If there is $2 of Junior, it is 50%. The protocol targets 90% utilization as the equilibrium point:

• Senior depositors need the 10% buffer. At 100%, the market closes to new Senior deposits because there’s no Junior left to back them.
• Junior depositors need utilization high enough that their boosted yield is meaningful. At low utilization, Junior’s premium gets diluted across the pool and the risk isn’t sufficiently compensated. At 90%, Junior earns real extra yield, and the curve steepens aggressively above that point; so when coverage gets tight, new Junior capital is strongly incentivized to show up.

​

Why Does This Matter?

Seniors get smart-contract-enforced downside coverage. Every Senior position has a quantified Junior buffer defined in the protocol’s contracts. This gives risk committees a concrete, verifiable loss-absorption layer. This enables Seniors to evaluate yield sources they might otherwise be prevented from accessing. Junior absorbs losses from the first dollar. There is no buffer on losses. Junior capital absorbs any Senior drawdown from the very first dollar, up to the full coverage amount. Seniors are not impaired until Junior capital is fully exhausted. For Juniors, this effect is similar to a levered position. Juniors benefit from an observation period. When the underlying strategy draws down, the protocol enters a time-bounded observation window before allocating losses. Temporary, expected volatility that reverses within the window does not slash Junior capital. Juniors only absorb actual, persistent losses, not noise. (Note that not all markets have an observation period. See Section 2 for details on when the observation period is triggered and how it resolves.) Juniors earn a premium for risk they already underwrite. Every yield source Dawn tranches already has LPs depositing into the underlying asset directly. Dawn lets those same participants earn a risk premium for formally taking the first-loss position, rather than simply accepting the base rate. This risk premium is paid by Senior positions.

​

The Vault Products

For investors who do not want to evaluate and manage individual Dawn markets, the protocol offers managed vaults. The Dawn Senior Vault (srRoyUSDC) is the foundational product, deploying USDC into Senior tranches across a diversified set of yield sources to offer buffered yield backed by Junior first-loss capital. Royco ETH (roywstETH) is built for ETH holders who want to earn yield without selling their ETH: it borrows USDC against wstETH collateral and deploys the proceeds into srRoyUSDC, capturing staking rewards plus the carry spread. Each vault is managed by a professional, independent curator.
