SENTINEL

HOW TO MINT

// Three steps. MetaMask → Claude → mint.

STEP 1 — Prepare MetaMask (enable hex data)

SentinelETH mints carry a small hex payload in the transaction data. MetaMask hides this by default — you need to turn it on so you can review what you're signing.

  1. Open the MetaMask extension.
  2. Click the sandwich menu (☰) in the top-right corner.
  3. Scroll down and click Settings.
  4. Choose Advanced (older builds: Transactions).
  5. Find “Show Hex Data” and toggle it ON.

Your MetaMask wallet is now ready to display the mint payload.

STEP 2 — Connect Claude to the SentinelETH MCP server

SentinelETH ships an MCP (Model Context Protocol) server so Claude can read collection state and build mint transactions for you. Connect it once, on either Claude.ai or the Claude Desktop app.

Option A — Claude.ai (web)

  1. Open claude.ai → Settings → Connectors.
  2. Click Add custom connector.
  3. Name it SentinelETH and paste the URL:
    https://sentineleth-mcp.onrender.com/mcp
  4. Save. Start a new chat — the SentinelETH tools should appear in the connector list.

Option B — Claude Desktop

  1. Open Claude Desktop → Settings → Connectors.
  2. Click Add custom connector and choose the URL (HTTP) transport.
  3. Paste the same URL as above (https://sentineleth-mcp.onrender.com/mcp).
  4. Save and restart Claude Desktop.

Claude Desktop also supports a JSON config — if you prefer that, add an entry under mcpServers with type: "http" and the URL above.

STEP 3 — Ask Claude to mint

With MetaMask ready and the connector live, just talk to Claude. It will check collection status, build the transaction, and walk you through signing it in MetaMask.

  • “How do I mint a SentinelETH?” — Claude explains the current phase, price, and per-wallet cap.
  • “Mint 1 (or more, up to 4) SentinelETH for me — <your wallet address>.” — Claude returns the exact to, value, and data for the transaction. Always include the wallet address you want the NFTs minted to.
  • Open MetaMask, paste / approve the transaction, and confirm the hex data matches what Claude returned.
  • Once the transaction confirms on Sepolia, your token shows up under My Holdings within ~30 seconds.
  • “Show me the NFTs and metadata I just minted.” — Claude can read your tokens and their on-chain metadata directly. Metadata propagates within 30 seconds to 1 minute after the mint transaction confirms.

Max 4 per wallet. Mint price and remaining supply are visible on the homepage and via Claude at any time.
