This skill is the narrower funding flow.\n\nFunding an agent wallet means putting USDC where the CLI can spend it. There are **two balance pools** to be aware of:\n\n- **On-chain (vanilla x402)** — USDC sitting at the wallet address on a specific chain. Each chain is separate. Used to pay endpoints whose `accepts[]` does not include `GatewayWalletBatched`. Settles in one block.\n- **Nanopayments (powered by Gateway)** — USDC held off-chain in your Circle Gateway balance, batched and settled for you across supported chains. Per source chain — no cross-chain pooling at payment time. Used to pay endpoints whose `accepts[]` includes `GatewayWalletBatched`. Settles in \u003C500ms once the balance exists.\n\n### Gas note\n**Agent wallet payment flows are gas-abstracted** — users can pay with USDC without pre-funding native gas. \n\nThis skill covers funding both pools. Pick the path with the shortest time-to-result and hide chain complexity from the user.\n\n## Prerequisites\n\n```bash\n# Confirm session is good\ncircle wallet status\n\n# Get the wallet address\ncircle wallet list --chain BASE --type agent --output json\n\n# Check current on-chain balance (per chain)\ncircle wallet balance --address \u003Caddr> --chain BASE --output json\n\n# Check current Gateway balance (per chain)\ncircle gateway balance --address \u003Caddr> --chain BASE --output json\n```\n\nIf `circle wallet status` errors with \"Not logged in\" or \"Terms acceptance is required\", hand off to the `use-agent-wallet` skill — it covers install, terms, login, and wallet creation.\n\n## Step 1 — Pick a funding path\n\nAsk the user: *\"How would you like to fund your wallet?\"*\n\n- **Fiat (USD or local currency)** — Buy USDC with a card or bank transfer via the CLI's built-in fiat on-ramp. Best for users who don't have crypto yet.\n- **Existing USDC** — Send USDC from a wallet they already have (MetaMask, Coinbase, Phantom, etc.). Faster and free of on-ramp fees.\n- **Gateway deposit (advanced)** — Move existing on-chain USDC into the Gateway balance for low-latency batched payments. Only useful if the seller they're paying supports Gateway on a specific chain.\n\n**Default recommendation: existing USDC → BASE.** Fastest, lowest friction, and BASE is the most commonly accepted chain across the marketplace.\n\n## Step 2 — Required flags for non-interactive use\n\nThe CLI prompts for missing values when run interactively. **Agents are non-interactive**, so every `circle wallet fund` invocation against mainnet MUST include:\n\n- `--address \u003Caddr>` — wallet address from `circle wallet list`\n- `--chain \u003Cchain>` — e.g. `BASE`\n- `--method \u003Cfiat|crypto>` — without it: `Error: --method is required in non-interactive mode.`\n- `--amount \u003Cnumber>` — USDC amount; without it: `Error: --amount is required.`\n\n`--token usdc` is the default and can be omitted, but pass it explicitly when the user asked for USDC specifically.\n\n## Path A — Fiat on-ramp\n\nOpens a fiat on-ramp window in the user's default browser. Funds deposit directly to the wallet on the selected chain.\n\n```bash\ncircle wallet fund --address \u003Caddr> --chain BASE --amount 25 --token usdc --method fiat --open\n```\n\nThe user completes purchase in the on-ramp window. USDC arrives in the wallet on the selected chain after on-ramp settlement (typically minutes for card, longer for bank transfer).\n\nVerify after the user reports purchase complete:\n\n```bash\ncircle wallet balance --address \u003Caddr> --chain BASE --output json\n```\n\n## Path B — Crypto transfer (existing USDC)\n\nThe user already holds USDC somewhere (another wallet, an exchange, etc.) and wants to send it to the agent wallet.\n\n### Recommended — browser-rendered QR (best UX)\n\n```bash\ncircle wallet fund --address \u003Caddr> --chain BASE --amount 10 --token usdc --method crypto --open\n```\n\n`--open` renders the EIP-681 QR code on a local HTML page in the user's default browser. Use this by default. **Terminal-rendered QR codes are frequently truncated or unscannable** inside agent UIs (Claude Code, Codex, etc.); the browser page renders the QR at full resolution and works on both desktop and mobile.\n\nThe user scans the QR with any mobile wallet (MetaMask, Coinbase Wallet, Rainbow, Phantom) and confirms the transfer.\n\n### Alternatives — PNG export or manual transfer\n\nIf the user can't scan a browser QR, READ `references\u002Fcrypto-transfer-alternatives.md` (QR-to-PNG via `--export`, manual transfer details including USDC contract addresses).\n\n### Verify after transfer\n\n```bash\ncircle wallet balance --address \u003Caddr> --chain BASE --output json\n```\n\n## Path C — Gateway deposit (powered by Gateway, advanced)\n\nOnly suggest a Gateway deposit when:\n\n- The user has on-chain USDC, AND\n- They want to pay a service whose `accepts[]` includes `GatewayWalletBatched` on a specific chain, AND\n- That chain is one Gateway supports (Polygon, BASE, ETH, ARB, OP, AVAX, UNI).\n\n### Eco vs direct — pick eco unless one of four conditions holds\n\n`circle gateway deposit --method eco` deposits BASE vanilla USDC into Gateway and **lands on Polygon** (Gateway domain 7) in ~30-50s for a $0.03 flat fee. The follow-up payment is `pay --chain MATIC`.\n\nUse `--method direct` **only** when:\n\n1. **The user explicitly asked for direct** — e.g. \"deposit on BASE without going to Polygon\", \"stay on BASE\", \"use direct deposit\". Implicit preferences and your own inferences do not count.\n2. **The source chain isn't supported by eco** — eco only supports BASE as a source today; check `circle gateway deposit --help` for the current list. Trying an unsupported source returns \"Unknown method\" or chain-not-supported.\n3. **The seller does NOT accept Gateway on Polygon** — verify by reading the seller's raw 402 `accepts[]` (not `circle services inspect`). Eco lands on Polygon, so if the seller can't pay there, the Gateway balance won't be reachable for this payment.\n4. **The user already has vanilla on a fast chain the seller accepts** — `direct --chain \u003Cfast-chain>` is ~8s **on the fast chains only (MATIC, AVAX)** and skips the eco fee. (e.g., user has 5 USDC vanilla on Polygon → `direct --chain MATIC`.)\n\nIf none of conditions 1–4 holds, **the answer is eco**. Picking direct anyway is slow on BASE: **direct on BASE (and ETH\u002FARB\u002FOP\u002FUNI) waits ~13–19 minutes for finality** + gas, vs eco's ~30-50s + $0.03. (The ~8s above is MATIC\u002FAVAX only — never quote it for BASE.)\n\n### Compare per-workflow, not per-call\n\nEco's cold-start (~30-50s + $0.03) is paid **once**; every Gateway call after is \u003C500ms. Vanilla has no deposit but every call costs ~2s forever with no amortization. Agentic workflows are rarely single-call, so treat the deposit as one-time wallet onboarding, not a per-call cost. (Time breakeven is ~N=7-13 calls, but Gateway-only seller access and \u003C500ms future calls already win at call 1.)\n\n### Eco deposit (BASE → Polygon)\n\n```bash\n# Deposit (--amount, --address, --chain, --method are all required)\ncircle gateway deposit --amount 10 --address \u003Caddr> --chain BASE --method eco\n\n# Verify (Gateway balance shows Polygon in the per-chain breakdown)\ncircle gateway balance --address \u003Caddr> --chain BASE --output json\n# First payment\u002Ftransfer on a new chain auto-deploys the wallet (see Troubleshooting).\n```\n\nOnce the deposit verifies, hand off to the `pay-via-agent-wallet` skill for the actual payment — that skill owns the `circle services pay` flow (including its allowed-tools whitelist and gotchas).\n\n**Common mistake:** using `--chain BASE` on the `pay` call when the Gateway balance landed on Polygon. The chain on `pay` must match where the balance lives.\n\n### Direct deposit and Gateway withdrawals\n\nWhen a condition for `--method direct` holds (above), or the user wants USDC back out of Gateway, READ `references\u002Fgateway-direct-and-withdraw.md` — direct command syntax, supported chains and timings, and the same-chain-only withdraw + `circle bridge transfer` pattern.\n\n## Troubleshooting\n\nOn ANY funding error (missing flags, unscannable QR, `Wallet not deployed`, `Insufficient balance`, wrong chain after eco, withdraw limits), READ `references\u002Ftroubleshooting.md` for the error table and reference links.\n\n## Rules\n\n- NEVER prompt users to send USDC to addresses you generated. ALWAYS use the user's own wallet from `circle wallet list`.\n- NEVER store, log, or display private keys.\n- ALWAYS pass `--method \u003Cfiat|crypto>` to `circle wallet fund` — agents are non-interactive and the CLI will not prompt.\n- ALWAYS pass `--amount \u003Cnumber>` to `circle wallet fund` — confirm the amount with the user first.\n- ALWAYS prefer `--method crypto --open` over rendering QR codes in the terminal — terminal QR codes get truncated inside Claude Code, Codex, and similar agent UIs and become unscannable.\n- For fiat: use `--method fiat --open` so the on-ramp loads in the browser.\n- NEVER suggest a Gateway eco deposit unless you have verified the target service supports Gateway on Polygon via the discovery API or the seller's raw 402 `accepts[]`.\n- NEVER deposit 100% of the user's vanilla balance into Gateway. The wallet needs vanilla headroom for vanilla-only sellers the user may hit next.\n- Sizing formula: `amount = max(price × N + fee + slack, Gateway minimum)`, where N is the workflow's expected call count. Typically reserve ~50% of vanilla as a soft headroom floor. Gateway enforces a server-side minimum deposit; sizing below it returns an error, so floor your suggestion to that minimum. Run `circle gateway deposit --help` for current bounds.\n- Surface to the user before depositing when the required amount is materially larger than the workflow's total cost (cheap-endpoint case: $0.0024\u002Fcall × 5 = $0.012, but the Gateway minimum sets the floor) or above the user's stated `--max-amount` cap. Don't silently deposit ~100× the task cost.\n- The first real transaction on a new chain deploys the SCA — there is no dedicated \"deploy\" command today. Consult `circle wallet --help` for the current options if a `Wallet not deployed` error appears.\n- ALWAYS use `--chain` matching where the balance lives. Eco lands on Polygon → `pay --chain MATIC`. Direct lands on the source chain → `pay --chain \u003Csame>`.\n- Gateway does NOT do cross-chain transfers at payment time. Source chain matters.\n- Abstract chain details from the user unless they explicitly want technical specifics. The user asked to fund the wallet; they don't need a tour of EVM finality.\n- If the `circle` CLI itself causes friction during funding (unexpected error, confusing output, missing capability), file feedback per the `use-circle-cli` skill's **Report friction (feedback)** section.\n\n## Alternatives\n\nTrigger the `use-agent-wallet` skill instead when:\n\n- The user has not yet logged in to the CLI or accepted Terms.\n- `circle wallet status` errors with \"Not logged in\" or \"Terms acceptance is required\".\n- The user is asking about wallet setup, login, or session state — not funding.\n\nTrigger the `pay-via-agent-wallet` skill instead when:\n\n- The user wants to call or pay for a paid x402 service.\n- Funding has completed and the user is ready to use the marketplace.\n- The user mentions `circle services pay`, `circle services search`, or any \"pay for\" prompt.\n\nTrigger the `agent-wallet-policy` skill instead when:\n\n- The user wants to set spending limits before funding (rare — most users fund first, set limits later).\n- The user mentions per-tx \u002F daily \u002F weekly \u002F monthly caps, spending policy, or wallet rules.\n\nFor cross-chain USDC moves the agent should use **`circle bridge transfer`** directly — it is part of the Circle CLI (see `references\u002Fgateway-direct-and-withdraw.md` for the withdraw-then-bridge pattern).\n\n---\n\nDISCLAIMER: This skill is provided \"as is\" without warranties, is subject to the [Circle Developer Terms](https:\u002F\u002Fconsole.circle.com\u002Flegal\u002Fdeveloper-terms), and output generated may contain errors and\u002For include fee configuration options (including fees directed to Circle); additional details are in the repository [README](https:\u002F\u002Fgithub.com\u002Fcirclefin\u002Fskills\u002Fblob\u002Fmaster\u002FREADME.md).\n",{"data":36,"body":49},{"name":4,"description":6,"allowed-tools":37},[38,39,40,41,42,43,44,45,46,47,48],"Bash(circle wallet status*)","Bash(circle wallet list*)","Bash(circle wallet balance*)","Bash(circle gateway balance*)","Bash(circle wallet fund *)","Bash(circle gateway deposit*)","Bash(circle gateway withdraw*)","Bash(circle wallet transfer*)","Bash(circle bridge transfer*)","Bash(circle blockchain*)","Bash(circle feedback submit*)",{"type":50,"children":51},"root",[52,61,84,96,151,158,168,173,179,435,456,462,473,506,516,522,542,613,624,630,635,722,727,732,790,796,801,807,887,905,910,916,937,943,1000,1006,1011,1042,1048,1074,1094,1184,1203,1209,1221,1227,1377,1398,1431,1437,1465,1471,1500,1506,1719,1725,1737,1760,1770,1802,1813,1826,1848,1852,1876],{"type":53,"tag":54,"props":55,"children":57},"element","h2",{"id":56},"overview",[58],{"type":59,"value":60},"text","Overview",{"type":53,"tag":62,"props":63,"children":64},"p",{},[65,67,73,75,82],{"type":59,"value":66},"For an overview of the Circle CLI's ",{"type":53,"tag":68,"props":69,"children":70},"strong",{},[71],{"type":59,"value":72},"full",{"type":59,"value":74}," capability set — bridging, smart contract execution, x402 payment, and more — see the ",{"type":53,"tag":76,"props":77,"children":79},"code",{"className":78},[],[80],{"type":59,"value":81},"use-circle-cli",{"type":59,"value":83}," master skill.
