02 — Operate

Install once — then just ask.

One command wires Aura into your agent. After that you move USDC by asking, not by wiring endpoints.

Then ask your agent:

“How much USDC did I receive this week?”

“What’s the balance of my main wallet?”

“Estimate the fee to withdraw 500 USDC to Base.”

FAQ

Answers before you get paid.

Six quick answers about wallets, custody, and getting paid in USDC.

Do I need crypto experience or a wallet?
No. Aura provisions a Circle Developer-Controlled Wallet for you — Circle manages the keys. You get a USDC receiving address and start free on testnet. If you can call an API, you can get paid.
Does Aura hold my money?
No. Aura is non-custodial — USDC settles to a wallet you control. Aura is the connector and the software around it, not a custodian of your funds.
What can my agent actually do?
Over MCP your agent gets 33 tools: check balances, see what you’ve received, estimate and request withdrawals, list escrows, and read treasury insights. Read tools are safe by default; money-moving tools are annotated and gated.
Which agents and hosts does it work with?
Any MCP client — Claude Desktop, ChatGPT, Cursor — plus a CLI and a TypeScript SDK. One install, every surface.
Which chains, and is it real USDC?
Native USDC on Arc (primary), Base, and Polygon, issued through Circle. Cross-chain moves use Circle’s CCTP.
What does it cost?
Free on testnet, no card. Production runs on a simple monthly SaaS plan — you keep what you receive; Aura doesn’t take a cut of your payments.
