Solid is a non-custodial financial app that lets you:
Deposit USDC/USDT
Earn yield automatically via soUSD
Spend your balance using the Solid Visa Card
Withdraw back to USDC at any time
Behind the scenes, Solid uses modern DeFi infrastructure — but abstracts the complexity away so you don't need to think about blockchains or transactions.
Solid is currently available as a web app at app.solid.xyz. A mobile app is coming soon.
