| 5 | ## General Rules |
| 6 | |
| 7 | ⚠️ STOP — You MUST read and strictly follow the shared runtime rules before proceeding. |
| 8 | Do NOT select or call any tool until all rules are read. These rules have the highest priority. |
| 9 | → Read [gate-runtime-rules.md](https://github.com/gate/gate-skills/blob/master/skills/gate-runtime-rules.md) |
| 10 | - **Only call MCP tools explicitly listed in this skill.** Tools not documented here must NOT be called, even if they |
| 11 | exist in the MCP server. |
| 12 | |
| 13 | ## Signing gate — Gate Verify MCP (mandatory) |
| 14 | |
| 15 | Before **any** MCP call to `dex_wallet_sign_transaction`, `dex_wallet_sign_message`, or **`dex_tx_x402_fetch`** (signing tools only — **`dex_tx_x402_checkin_preview`** is not a signing call and does **not** require prior `tx_checkin`): |
| 16 | |
| 17 | 1. User must pass the existing confirmation gates (preview / message text / payment intent) for that operation. |
| 18 | 2. Agent **MUST** call the **Gate Verify** HTTP MCP server (see **Gate Verify MCP** under [MCP Server Connection Detection](#mcp-server-connection-detection)) tool **`/v1/tx/checkin`** or **`tx_checkin`** per `references/tx-checkin.md` and treat success as a **hard prerequisite**. **Do not** run the legacy **`tx-checkin`** shell binary or require the user to execute local check-in commands. Discover the verify server by scanning configured MCP servers until **`tools/list`** includes the check-in tool. **Auth:** pass **`authorization`** in the check-in tool **`arguments`** with the **same `mcp_token`** as wallet MCP calls — **not** by copying the wallet server’s HTTP **`headers`** onto the Verify MCP entry — see `references/tx-checkin.md`. |
| 19 | 3. After **`dex_tx_transfer_preview`**, the check-in **`message`** argument **must** be the preview field **`txBundle`** string **only** — **do not** assemble txbundle JSON from `unsigned_tx_hex` or other fields (see `references/tx-checkin.md`). |
| 20 | 4. **x402 (`dex_tx_x402_fetch`)**: **Do not** call `dex_tx_x402_fetch` first to probe 402. For **EVM exact / EIP-3009** (e.g. CoinGecko Pro x402 on Base), **first** call wallet MCP **`dex_tx_x402_checkin_preview`** — it returns the **`tx_checkin`** payload (including the correct 64-hex **`message`**) and **`x402_payment_required_b64`** so the agent never hand-builds the EIP-3009 digest. **Then** complete Gate Verify **`/v1/tx/checkin`** / **`tx_checkin`** using **`authorization`** (same **`mcp_token`**) together with the **`tx_checkin`** fields returned by preview. **Then** call **`dex_tx_x402_fetch`** with the same `url` / `method` / `body` / `headers` as preview, **`checkin_token`** from Verify, and the **same** **`x402_payment_required_b64`** from the preview result. For **POST JSON**, include **`Content-Type: application/json`** in the `headers` JSON on **both** preview and fetch (avoids common **415**). Full ordering and Solana / upto exceptions: `references/x402.md`, `references/tx-checkin.md`. |
| 21 | 5. Other single-step MCP tools that sign internally: same **`/v1/tx/checkin`** call **immediately before** the wallet MCP tool when the gateway requires it; follow backend docs for `checkin_token` / intent payload. |
| 22 | |
| 23 | ## Applicable Scenarios |
| 24 | |
| 25 | Use this skill when the user wants to **manage their on-chain wallet account, identity, or assets**: |
| 26 | |
| 27 | - Authenticate or manage sessions (login via Google or Gate OAuth, logout) |
| 28 | - Query token balances, total portfolio value, or wallet addresses |
| 29 | - View transaction history or past swap records |
| 30 | - Transfer or send tokens to an address (single or batch); **mandatory Gate Verify MCP check-in** (`/v1/tx/checkin`) before any signing (`references/tx-checkin.md`) |
| 31 | - Withdraw or cash out **on-chain** to their Gate Exchange account (deposit address resolved for their UID; not CEX-internal balance moves from this skill) |
| 32 | - Pay for HTTP 402 resources via x402 protocol (EVM exact/upto, Solana exact/upto); **`dex_tx_x402_checkin_preview`** (EVM EIP-3009) then **Gate Verify MCP check-in** then **`dex_tx_x402_fetch`** (`references/x402.md`, `references/tx-checkin.md`) |
| 33 | - Interact with DApps (connect wallet, sign messages, approve tokens, call contracts) |
| 34 | - Use the gate-wallet CLI tool for any of the above |
| 35 | - Detect or configure MCP Server connectivity |
