The best risk-adjusted USDC yield across DeFi

Gauntlet USD Alpha is a DeFi vault strategy that automatically rebalances USDC into a mix of stablecoin yield opportunities across chains, with the stated main goal of maximizing risk-adjusted, real yield. The strategy is built on Base and draws from over 200 stablecoin vaults across more than 10 networks and dozens of protocols. According to the page, its backtest weighted yields from vaults.fyi averaged 4.5% as of June 2025, after ranging from 5% to 15% over the prior year. The page says the strategy caps risk-on stablecoins at a 40% parameter, and that individual users can deposit USDC non-custodially through The Gauntlet App.
