Bảo mật ở cấp phần cứng cho các tác nhân AI tự động giao dịch crypto vừa có bước tiến đáng chú ý. MoonPay công bố tích hợp công nghệ Secure Element của Ledger vào các AI agent giao dịch, nhằm khắc phục lỗ hổng lâu nay khi khóa riêng tư được lưu trong môi trường kết nối internet. Với kiến trúc mới, khóa riêng tư được giữ trong mô-đun bảo mật phần cứng của Ledger, còn AI chỉ chuẩn bị giao dịch bên ngoài, giảm nguy cơ bị tấn công.
Hệ thống cũng bổ sung “guardrails” lập trình được để đặt giới hạn giao dịch, như chỉ hoán đổi giữa các tài sản nhất định hoặc giới hạn giá trị mỗi lệnh. Đồng thời, cơ chế thực thi theo “ý định” cho phép người dùng chỉ cần nêu mục tiêu giao dịch, còn AI tự xử lý bridge và thanh khoản đa chuỗi.
Theo dữ liệu từ Circle, hơn 140 triệu giao dịch AI-to-AI trong đầu năm 2026 chủ yếu được thanh toán bằng USD Coin. Song song đó, Worldcoin cũng triển khai xác thực khuôn mặt để xác minh danh tính người dùng trong các giao dịch AI giá trị cao.
