Circle Agent Stack gives agents a way to do more than generate a market summary. In this tutorial, build a research-first trading thesis agent that can use an Agent Wallet, discover Arrays market data, pay with USDC, stay within a budget, and return a thesis with receipts. No trade execution. Just paid data, reasoning, and spend tracking in one workflow.

An agent wallet is not just a crypto wallet with an API. It needs programmable spending limits, multi-party authorization, real-time risk controls, and a recoverable state if execution fails mid-transaction. That is one of the infrastructure problems on the table at Agentic Finance Summit. New York @Techweek_·

Where your agent's signing key lives is a design choice. Q402 gives three modes: - your EOA signs locally - an exported Agent Wallet key signs in-process - a server-custodied wallet signs on Q402's side All three settle gasless through the same relay. npx -y @quackai/q402-mcp

AI agents can plan the work and Circle Agent Wallet helps them pay for it. This tutorial walks through how to: → Create your first wallet → Fund it with USDC → Pay for services → Return receipts as part of the task

We shipped it, the 🦊 Agent Wallet is live for everyone today, a huge milestone for the team Agents can research, plan and decide (24/7). The moment they need to move money onchain, everything has historically gotten fragile. A self-custodial wallet built for autonomous execution: you set the spend limits, protocols and risk profile, the agent stays inside them. Gasless, batched, security checks on every transaction. I've spent most of this year close to this product, and the reason it matters to me isn't the agent — it's the rails. Autonomous finance doesn't work until the execution layer is boring and safe. Today it got a lot closer. If you build anywhere near trading, agents and crypto, take a look and come say HI. none of this ships alone. built with: @HyperliquidX — perps execution, the venue agents actually want @Polymarket — prediction markets, because agents are good at pricing beliefs @aave — idle capital doesn't have to sit idle @CoWSwap — mev-protected, intent-based swaps. agents get filled, not sandwiched @lifiprotocol — cross-chain routing so the agent doesn't care what chain the opportunity is on @blockaid_ — every transaction screened before it signs @cubistdev — the key management that makes autonomous signing safe to run unattended @awscloud — the infra underneath all of it 🧡

Q402 agents can now earn yield on @lista_dao. Idle stablecoins in a dedicated Agent Wallet earn in Lista vaults on @BNBCHAIN through one gasless MCP call. Your keys stay on your machine, separate from your main wallet. Built by @QuackAI_AI Come and join us:
