Duo Token Model

Aspida's LSD operates on a dual-token model consisting of the wrapped token, aETH (a deposit certificate of native ETH tokens wrapped 1:1 with ETH), and saETH (ERC4626), the staking token representation minted upon aETH staking.

Primarily, aETH serves as a means for protocol-controlled liquidity provision, significantly enhancing liquidity efficiency. The amount of saETH staking yield increases as users hold more aETH (with no yield). This dual-token model allows users the freedom to choose the yields they wish to capture, whether from liquidity provision or staking.
