StakeStone is an omnichain liquidity asset protocol that introduces liquid staking tokens (LSTs) for Ethereum (ETH) and Bitcoin (BTC), specifically STONE and SBTC, respectively. These tokens allow users to stake their ETH and BTC to earn staking rewards while maintaining liquidity. StakeStone's architecture supports integration with various staking pools and is designed to be compatible with future restaking functionalities. The protocol employs an Optimizing Portfolio and Allocation Proposal (OPAP) mechanism, enabling decentralized optimization of asset allocation to maximize staking yields. Built on LayerZero, STONE functions as an Omnichain Fungible Token (OFT), facilitating seamless cross-chain transfers and interoperability across multiple blockchains. This design provides users with flexibility in managing their staked assets across different networks. Additionally, StakeStone offers a multi-chain liquidity market centered around its native tokens, providing users with diverse use cases and enhanced yield opportunities.
