What is SolidYield?

Solid is a DeFi protocol that provides users with a self-custodial interface to earn yield on stablecoins, perform cross-chain operations, and spend assets via a debit card. It centers on SoUSD, a yield-bearing stablecoin minted by depositing USDC, where the token represents shares in a vault that allocates funds to audited DeFi strategies across chains, causing its exchange rate to increase over time as yields compound without staking or lockups.

The system processes deposits into vaults like BoringVaults for strategies involving protocols such as Pendle and Morpho, supports gasless transactions for certain actions, and enables spending through a Visa card integration with cashback options. Users maintain control via smart accounts and passkeys, with chain abstraction handling cross-EVM and compatible network interactions.
