Show HN: PolicyLayer – Non-custodial spending limits for AI agents (www.policylayer.com)

PolicyLayer has introduced a non-custodial solution that addresses the critical security concerns of AI agents by enforcing spending limits and transaction policies before approval. This innovative tool allows developers to set customizable parameters such as daily spending caps, transaction limits, and recipient whitelists, thereby mitigating risks associated with rogue AI actions or exploitation. The technology employs robust cryptographic methods, including SHA-256 fingerprinting and one-time-use JWT tokens, to ensure that any unauthorized modification of transaction details results in immediate rejection, making it nearly impossible for attackers to exploit the system. This development is significant for the AI/ML community as it fosters safer interactions between autonomous agents and financial systems, enabling wider deployment of AI applications without compromising security. By decentralizing control and eliminating the need for human approvals on every transaction, PolicyLayer streamlines processes while maintaining strict oversight. Its ease of integration—requiring just five lines of code—makes it accessible for both startups and enterprises, promoting responsible innovation in AI-driven finance. As organizations increasingly rely on AI for transactions, PolicyLayer's approach could transform how digital assets are managed and safeguarded in automated environments.
