Spiral Stake is a non-custodial leveraged looping protocol that amplifies yields on yield-bearing assets using flash-loan leverage on Morpho lending markets. The protocol works with any yield-bearing collateral that has a Morpho market - staked stablecoins like sUSDe, yield-bearing ETH like wstETH, and non-correlated directional markets like ETH/USD and BTC/USD. You get full control over your positions once they’re open. Add collateral, repay some debt, increase your leverage, withdraw collateral, or borrow against it without having to close and reopen. The core idea is simple. The protocol exploits the spread between what your collateral earns and what it costs to borrow against it. When collateral yield is higher than the borrow rate, leverage amplifies that positive spread. Spiral Stake automates the entire loop into one atomic flash-loan transaction, so there’s no multi-step execution risk and gas costs stay low.
