Solid USD (soUSD)

SOLID is a full-stack DeFi protocol that lets users earn, spend, and save directly from their self-custodial wallet. At its core is SoUSD, a yield-bearing, gasless, cross-chain stablecoin. With SOLID: 1. You earn passive income via BoringVaults, a curated DeFi yield engine. 2. You spend directly with the SOLID Card, both online and in stores (coming soon). 3. You operate across chains, with zero gas, signatures, or bridges. SOLID is designed for users who want control, clarity, and composable value—without blockchain headaches.
