Will AI Ever Be Good Enough to Not Need Spending Limits?
As AI agents improve, will they become reliable enough to handle money without guardrails? We argue that deterministic policy layers will always be necessary—and that's a feature, not a bug.
Non-Custodial Security: Why We Don't Want Your Keys
PolicyLayer enforces spending policies without ever touching your private keys. Learn how non-custodial architecture enables compliance without custody risk.
The Kill Switch: Emergency Controls for Autonomous Fleets
How to instantly halt all AI agent spending with a single click when bugs or attacks are detected in your autonomous fleet.
Under the Hood: How Two-Gate Enforcement Works
Technical deep-dive into PolicyLayer's two-gate cryptographic architecture that prevents transaction tampering without holding private keys.
The Anatomy of a Wallet Drain: How One Logic Loop Cost $100k
Case study of how a simple infinite loop bug can drain an AI agent's entire wallet in seconds, and how velocity limits prevent catastrophic loss.
Why Prompt Engineering is NOT Security: The Case for Policy Engines
System prompts can be jailbroken. Learn why deterministic policy engines are the only way to secure AI agent wallets against prompt injection attacks.
The Binary Permissions Problem: Why Traditional Wallets Fail AI Agents
Traditional crypto wallets offer all-or-nothing access. Learn why AI agents need granular policy layers between binary permissions.
Multisig vs Policy Layers: Which Approach Secures AI Agents Better?
Compare multisig wallets and policy layers for AI agent security. Learn when to use each approach—and why the best answer is often both.
ERC-20 Approval Attacks: Why AI Agents Are the Perfect Target
How infinite approval attacks work, why AI agents are uniquely vulnerable, and how to prevent token drain with intent-level controls.
Custodial vs Non-Custodial: The Key Architecture Decision for AI Agent Wallets
Should you give your AI agents their own keys or use a custodial service? The trade-offs, risks, and when to use each approach.
Securing the X402 Protocol: Why Autonomous Agent Payments Need Spending Controls
Deep dive into X402 protocol security risks and why autonomous AI agents need policy enforcement to prevent wallet drainage and payment attacks.
