About DeFindex
DeFindex is yield infrastructure for wallets, neobanks and fintech apps. It lets developers add stablecoin savings to an existing product through a REST API and SDK, without writing smart contracts. Vaults are described as non-custodial, use automated yield strategies with rebalancing, and support USDC, EURC and other Stellar assets. The company reports live partner deployments across LATAM, EMEA and APAC.
Integration is supported by documentation with step-by-step guides and code examples; a sample deposit flow initializes the SDK, generates a deposit transaction, has the user's wallet sign it, and sends it to the network. Smart contracts are described as audited, with a linked audit report. Pricing, revenue-share terms and expected yields are not stated on the homepage.
