Circle Releases Agent Wallets Template for Mastra Developers

October 20, 2026

Circle has released a Circle Agent Wallets template for developers building with Mastra, the AI agent framework. The template lets developers add a USDC-powered wallet to an agent so it can pay for APIs and services and transact onchain, without custom integration code.

Agents can find marketplace services, estimate costs, and buy responses with USDC after user-approved payments, per Mastra's template page
Extends Circle's Agent Stack push to put programmable money inside the tools AI developers already use The announcement follows Circle's broader Agent Stack rollout, which also supports OpenAI Agents SDK, Claude Agent SDK, LangChain, Vercel AI SDK, and Google AI ADK.
