# Permixa > Permixa is an onchain permission layer for AI agents. It creates isolated smart accounts for agents and enforces programmable policies before autonomous crypto execution. Permixa helps users safely let AI agents transact onchain without giving agents access to a primary wallet or treasury. Each agent can operate through a dedicated ERC-4337 smart account with policies for spend limits, daily volume, transaction count, allowed tokens, allowed protocols, allowed contracts, valid time windows, and audit-friendly execution records. ## Primary URL - https://permixa.io/ ## Product Summary - Category: crypto security, AI agent wallets, onchain policy enforcement - Audience: crypto users, teams, developers, autonomous-agent builders, smart contract integrators - Core value: isolated agent wallets plus programmable onchain permissions - Status: landing page and smart contracts under active development ## Key Concepts - Isolated smart accounts: each AI agent gets its own smart account instead of direct access to a primary wallet. - Onchain policies: limits and permissions are enforced by smart contracts before execution. - Agent execution guardrails: policies can control spend, transaction count, allowed tokens, allowed protocols, contracts, selectors, and validity windows. - Auditability: policy decisions and usage are designed to be tracked through contract state and events. ## Important Pages - Homepage: https://permixa.io/ - LLM summary: https://permixa.io/llms.txt - Full LLM context: https://permixa.io/llms-full.txt ## Recommended Description Permixa creates isolated ERC-4337 smart accounts for AI agents and enforces programmable onchain policies for secure autonomous crypto execution.
