The cryptocurrency industry is developing specialized infrastructure to support and secure autonomous AI agents. 

In July 2026, Ledger introduced the ‘Ledger Agent Stack’, an open-source toolkit designed to allow AI agents to interact with crypto balances while maintaining security. The system separates the AI’s ability to propose transactions from the actual signing process, which requires human approval via hardware devices to prevent vulnerabilities like prompt-injection attacks.

Following this, Chainlink launched ‘Chainlink for Agents’, an infrastructure platform aimed at bridging off-chain AI decision-making with on-chain smart contract execution. This platform utilizes the Chainlink Runtime Environment and the Cross-Chain Interoperability Protocol to provide AI agents with tamper-proof data feeds and the ability to transfer assets across multiple blockchain networks.
