Valha is a DeFi abstraction layer for developers. It enables Web3 DApps, wallets, and investment platforms to integrate DeFi protocols into their interfaces and offer investment opportunities to their end users. Valha maintains a RESTful API for standardized interaction commands with underlying DeFi protocols (deposit, redeem, stake, unstake, claim). It covers 25 DeFi protocols on many chains and every DeFi vertical, including lending, liquid staking, LPs, and yield aggregation. Also, Valha develops a set of smart contracts to execute batch transactions (zap-in, zap-out) and enable client companies to monetize features by setting up transaction fees.
