DeFi—stusdGG

Staked usdGG

Staked usdGG

When users deposit USDC into the Genius Protocol, they receive usdGG, a 1:1 fully backed receipt token that passively accrues yield from cross-chain swap fees. The problem is that while usdGG appreciates in value relative to its backing (each token is worth more than 1 USDC over time), it is non-rebasing and not natively DeFi-compatible with protocols that expect fixed-value stablecoins. Holding usdGG earns yield, but it cannot easily be used as collateral or LP capital without sacrificing the underlying fee accrual benefits.

To solve this, users can stake their usdGG to mint stgusdGG, a liquid staking token (LST) that represents a claim on usdGG + accrued yield. stgusdGG maintains a fixed 1.0 unit representation, while usdGG itself appreciates in backing value. When a user wants to exit, they redeem stgusdGG back to usdGG and then usdGG to USDC, receiving the full yield earned during the staking period.

This mirrors what stETH does for Ethereum: it decouples the yield-bearing asset (usdGG) from its liquid wrapper (stusdGG), enabling seamless integration with DeFi protocols. A user can hold stgusdGG in Curve, use it as collateral in lending markets, or LP it in Uniswap-style pools – all while their position continues to benefit from swap fee revenue, abstracted away inside the usdGG backing.
