SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Getting USDC into a Circle agent wallet involves choosing between fiat on-ramps, crypto transfers, and Gateway deposits, each with different chains, fees, and settlement times. This Skill guides the agent through picking the right funding path and executing it correctly with the Circle CLI, avoiding common errors like missing non-interactive flags or paying on the wrong chain. ## Core Features & Use Cases - Fiat on-ramp: Buy USDC with USD or a credit card through a browser-based on-ramp that deposits directly to the wallet on the selected chain. - Crypto transfer: Send existing USDC from wallets like MetaMask or Coinbase using a browser-rendered EIP-681 QR code, exported PNG, or manual transfer details. - Gateway deposits: Move on-chain USDC into the Gateway Nanopayments balance via eco (BASE to Polygon, ~30-50s, $0.03) or direct (same-chain) methods for sub-500ms batched payments. - Use Case: A user's agent wallet shows a low balance before calling a paid x402 service. The Skill checks balances, recommends sending existing USDC to BASE, renders a QR code in the browser, and verifies the deposit. ## Quick Start Ask the agent to fund your Circle agent wallet with 10 USDC on BASE using a crypto transfer QR code.

Frequently Asked Questions about fund-agent-wallet

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fund a Circle agent wallet with USDC?▼

Run circle wallet fund with the wallet address, chain, amount, and method flags. Use --method fiat --open to buy USDC with a card in the browser, or --method crypto --open to get a QR code for sending USDC from an existing wallet.

What is the difference between Gateway eco and direct deposit?▼

Eco deposit moves BASE USDC into Gateway and lands on Polygon in about 30-50 seconds for a $0.03 flat fee. Direct deposit stays on the source chain but takes 13-19 minutes on slow chains like BASE or ETH, so eco is preferred unless specific conditions apply.

Do I need ETH for gas when paying from a Circle agent wallet?▼

No. Agent wallet payment flows are gas-abstracted, so users pay with USDC only and never need to pre-fund native gas tokens like ETH on the wallet.

Why does circle wallet fund fail with '--method is required in non-interactive mode'?▼

Agents run non-interactively, so the CLI cannot prompt for missing values. Always pass --method fiat or --method crypto along with --address, --chain, and --amount on every circle wallet fund call.

Why is the QR code from circle wallet fund unscannable in the terminal?▼

Terminal-rendered QR codes are frequently truncated inside agent UIs like Claude Code or Codex. Re-run with --open to render the QR in the browser at full resolution, or use --export to save it as a PNG file.

Can I withdraw USDC from Gateway to a different chain?▼

No, circle gateway withdraw is same-chain only in v1. To move USDC across chains, withdraw on the same chain first and then use circle bridge transfer for the cross-chain move.
