DeFi Protocol

DeFi (Decentralised Finance) protocols are open-source smart-contract applications that replicate financial services, including exchanges, lending platforms, derivatives markets, and insurance products, without a central operator. Users interact directly with the contracts using their own wallets, retaining custody throughout.

The DeFi space is disproportionately affected by fraud and exploitation because it combines large pools of value, novel technology that users often do not fully understand, and a culture of moving fast without traditional regulatory oversight. Common threats include protocol exploits, rug pulls by developers who retain admin keys, oracle manipulation, and flash-loan attacks.

For consumers evaluating a DeFi protocol, key trust signals include: length of time in operation without major incidents, total value locked history, public and reputable team, multiple independent audits, and absence of privileged admin functions that could be exploited or abused by insiders.
