What is Shieldz Crypto Payments?
The crypto-payments capability enables AI agents to interface directly with Shieldz network services, allowing users to generate non-custodial, keyless payment links and reusable tip jars without needing an API key or a central account. Operating directly with user-owned wallets, this skill settles funds straight to the destination address on networks such as Base, Arbitrum, Optimism, Polygon, and Ethereum. As a utility within the Openclaw Skills ecosystem, it removes intermediaries, ensuring you retain control over your funds and private keys.
This integration is structured around user safety. It requires explicit confirmation and wallet verification before performing external actions, making it a reliable, user-guided tool for digital invoice generation and payment tracking within your terminal or Model Context Protocol (MCP) environment.
Shieldz Crypto Payments Use Cases
- Generating a fixed-amount crypto payment link (e.g., in USDC on Base) for a customer order during an automated chat workflow.
- Creating a reusable, pay-what-you-want tip jar with suggested payment amounts for content creators or developers.
- Checking the status and total received amount of an existing payment link using a secure manage token.
- Integrating automated invoice workflows into agentic chat systems that require immediate blockchain settlement.
How Shieldz Crypto Payments Works
- User Request and Confirmation: The agent identifies a payment-related command and prompts the user to explicitly confirm the target wallet, blockchain network, asset type, and transaction amount.
- External REST/MCP Call: Once the user grants consent, the skill sends a secure request to the Shieldz API (or remote/local MCP server) transmitting only the specified wallet, asset details, amount, and optional user-consented email.
- Link Generation: The Shieldz service returns a public payment URL alongside a private management URL and token.
- Delivery: The agent presents the safe, shareable payment URL to the user or payee while warning the user to store the sensitive management token securely.
- Status Verification: Upon future request, the agent queries the Shieldz status endpoint with the user-provided management token to check real-time settlement progress.
Shieldz Crypto Payments Setup
The Shieldz payment integration can be run via direct REST API calls or configured as an MCP server. For the MCP setup, you can run the server locally using a pinned npm package.
To run the local MCP server, use the following execution command:
npx -y @shieldz/[email protected]
Alternatively, you can query the keyless REST API directly. Below is an example curl command to generate a fixed-amount link:
curl https://shieldz.cash/api/v1/links \
-H "Content-Type: application/json" \
-d '{
"settlement": { "chain": "BASE", "asset": "USDC", "address": "0xUserProvidedWallet" },
"amount_usd_cents": 4900,
"memo": "Order #1234"
}'
