Agent hijacking is a security threat in which an autonomous software agent is manipulated or taken over by an unauthorized party. This can occur through vulnerabilities in code, malicious inputs, or compromised permissions that alter the agent’s intended behavior. In systems that rely on AI agents, such as automated trading or blockchain interactions, hijacking can lead to unauthorized transactions or harmful decisions. The risk is particularly relevant in crypto environments where agents may control wallets or execute smart contract operations. Preventing agent hijacking involves implementing strong security practices, including access controls, validation mechanisms, and continuous monitoring.
Coinbase CEO Brian Armstrong has pushed back against suggestions that artificial intelligence competes with crypto, arguing instead that AI agents are driving massive demand for programmable blockchain payments.
Coinbase says AI now helps produce between 95% and 100% of its code, with most engineers operating multiple agents as the exchange restructures around AI-native teams.
AgentCard provisions AI agents with Visa tokens, dedicated emails, phone numbers, and crypto wallets via a single API.
