Dexter provides a non‑custodial payment layer that lets autonomous agents operate with their own on‑chain accounts and spend within user‑defined caps. Each agent receives a virtual card that meters calls in real time, settling only the amount earned and preventing overspend, all secured by the user’s passkey on Solana. The system works without a separate wallet app, using Face ID authentication and open‑standard rails for seamless integration.

Problem
Developers of autonomous agents need a way to pay for each API call without exposing their wallet to overspending or requiring complex custodial solutions. Existing payment models often rely on custodial accounts or manual approvals, leading to security risks, unexpected fees, and operational overhead.
Solution
Dexter offers a non‑custodial money layer that assigns each autonomous agent its own on‑chain “tab” with a hard spending cap set by the user. Payments are metered per API call and settled in real time on the Solana blockchain, ensuring that an agent can only spend up to its predefined limit. Authorization is performed via Face ID on the user’s iPhone, eliminating the need for separate wallet apps or browser extensions. All funds remain under the user’s control, with no custodial intermediaries, and the system enforces caps directly on‑chain, preventing overages and unexpected charges.
Target Audience
Primary customers are developers and enterprises that deploy autonomous AI agents—such as trading bots, data‑scraping services, and media generation tools—who require secure, programmable payment controls.
