Overview
- PayBox, which MoonPay launched on Wednesday, July 29, 2026, is a live noncustodial vault that connects AI assistants such as ChatGPT and Claude to payments and on‑chain actions via conversational connectors.
- Users link a wallet or card to PayBox, pick Always Ask for one‑time passkey approval or Autonomous to set bounded spending limits and rules, and then approve each change with a fresh passkey.
- The service supports Solana plus multiple EVM‑compatible networks including Ethereum, Base, Arbitrum, Polygon, Hyperliquid, Tempo and Robinhood Chain and can handle fiat‑to‑crypto buys, swaps, bridges, DeFi deposits, bookings and online purchases.
- Security relies on Sodot’s multiparty computation and secure hardware to split private keys so neither MoonPay nor the connected AI can alone access full keys, and card flows use Visa’s agentic commerce protocol and x402 to avoid exposing raw card numbers.
- Market watchers say PayBox could raise on‑chain utility and demand for networks like Solana over time but note the launch has produced little immediate change in short‑term price signals.
