The StakeLayer is a comprehensive yield aggregator designed primarily for BTC (WBTC, BTCB), ETH, and stablecoins like USDT/USDC. Its core functionality revolves around a system of vaults enabling users to stake funds and receive staked tokens (e.g., sWBTC, sBTCB) in return. Additionally, the project incorporates secondary vaults for staking these staked tokens, facilitating the aggregation of yield. Complementing this architecture is a strategy manager backend responsible for identifying the most lucrative yield-generating investments.
