sCUSD (Staked CUSD)

Introduction

sCUSD is a yield-bearing derivative of CUSD, implemented as an ERC-4626 vault. Users deposit CUSD into the vault to mint sCUSD, which accrues yield over time based on the protocol’s fee revenue.

Technical Implementation

  • ERC-4626 Vault:

    • The sCUSD vault adheres to the ERC-4626 tokenized vault standard, ensuring interoperability with other DeFi protocols.

    • Users deposit CUSD to mint sCUSD at a 1:1 ratio initially, with the sCUSD balance appreciating over time as vault assets increase.

  • Yield Generation:

    • Yield is generated through the auctioning of protocol-collected swap fees, as described in the Chad Swap section.

    • Auction proceeds, denominated in CUSD, are deposited into the sCUSD vault, increasing the total assets under management (AUM).

    • The vault’s share price, ( P ), is calculated as:

    P=(Total Assets/Total sCUSD Supply)

where total assets include deposited CUSD plus accumulated auction proceeds.

  • Volatility-Driven Yield:

    • The yield for sCUSD is directly tied to market volatility, as higher volatility increases trading volume on Chad Swap, leading to higher fee collection and, consequently, higher auction proceeds.

    • This creates a risk-free yield stream, as sCUSD holders are not exposed to collateral risk, unlike traditional vault strategies.

Redemption Support

The auction mechanism also serves as a secondary redemption mechanism for CUSD, supporting its price in the secondary market:

  • Arbitrage Opportunity: If CUSD trades below its peg, arbitrageurs can purchase CUSD at a discount and use it to bid in fee auctions, profiting from the difference.

  • Price Support: This creates additional demand for CUSD, helping to stabilize its peg in the secondary market.

Risk Considerations

  • Yield Variability: Yield is not fixed and depends on trading volume and market volatility. Periods of low volatility may result in lower yields.

  • Smart Contract Risk: The sCUSD vault is subject to smart contract risks, mitigated through rigorous auditing and formal verification.
