Full overviewShow less
The protocol offers three core products: STONE (liquid staking ETH earning 5.8-7.2% APY), SBTC (liquid index BTC), and STONEBTC (yield-bearing BTC derivative).
StakeStone's Optimized Portfolio Allocation Protocol (OPAP) uses AI analytics to automatically distribute user assets across staking pools, restaking protocols, and DeFi yield platforms to maximize risk-adjusted returns. Launched in 2023, the protocol has accumulated over $12B in TVL according to Chainlink Research, making it one of the largest liquid staking infrastructure providers.
StakeStone 2.0, launched in December 2025, introduced enhanced AI-driven optimization and gasless transactions via EIP-7702. The STO governance token powers the vote-escrowed (veSTO) system for protocol governance and includes a deflationary Swap & Burn mechanism.
The project raised $22M in funding led by Polychain Capital with participation from Binance Labs and OKX Ventures. Currently trading at rank #615 with a $30.7M market cap, STO has 230M tokens circulating out of a 1B maximum supply.
