What is PaySpawn?
PaySpawn is a specialized financial control layer designed for autonomous agents that need to handle real-world value. By integrating this skill with Openclaw Skills, developers can grant their agents the ability to pay for APIs, services, and transactions while maintaining strict security through smart contract enforcement on the Base network.
Instead of exposing sensitive private keys, PaySpawn uses scoped spending credentials. These credentials encode specific permissions, such as daily spending caps and per-transaction limits, which are validated directly on-chain. This ensures that even if an agent's environment is compromised, the potential financial loss is strictly capped by the immutable logic of the smart contract.
PaySpawn Use Cases
- Enabling autonomous agents to pay for x402-enabled AI APIs and data services.
- Restricting agent spending to specific authorized recipient addresses via allowlists.
- Setting daily USDC allowances for automated procurement or trading bots.
- Managing financial risk for agents operating in unattended or public environments.
- Distributing small, controlled budgets to a fleet of specialized worker agents.
How PaySpawn Works
- The wallet owner connects to the PaySpawn dashboard and approves a USDC spending ceiling.
- Spending constraints like daily caps and per-transaction limits are defined and signed as an EIP-712 credential.
- The generated credential string is configured in the agent's environment, providing permission without sharing the private key.
- When the agent initiates a payment, the SDK passes the credential to the PaySpawn V5 smart contract on Base.
- The contract verifies all limits in real-time; any transaction exceeding the set bounds is automatically reverted by the blockchain.
PaySpawn Setup
To get started with PaySpawn and Openclaw Skills, install the SDK and configure your spending permissions:
npm install @payspawn/sdk
- Visit the PaySpawn dashboard at payspawn.ai/dashboard and connect your Base wallet.
- Approve the USDC spending ceiling and set your desired daily and per-transaction limits.
- Sign the credential and copy the resulting string.
- Set the
PAYSPAWN_CREDENTIALenvironment variable in your agent configuration.
PaySpawn Data Schema & Taxonomy
| Property | Type | Description |
|---|---|---|
| PAYSPAWN_CREDENTIAL | String | Base64-encoded spend permission containing scoped limits. |
| Daily Cap | Decimal | The maximum amount of USDC the agent can spend per 24-hour window. |
| Per-Transaction Cap | Decimal | The maximum USDC amount allowed for a single payment. |
| Address Whitelist | Array | Optional list of Ethereum addresses the agent is permitted to pay. |
| Expiry | Timestamp | The date after which the spending credential is no longer valid. |
PaySpawn Advanced Features
- Fleet Mode Provisioning: Generate multiple unique credentials from a single shared USDC funding pool for large-scale agent deployments.
- x402 Auto-pay Integration: Automatically handle HTTP 402 Payment Required responses from modern API providers.
- On-chain Revocation: Instantly pause or kill an agent's spending ability directly on the blockchain via the dashboard or SDK.
- Permission Scoping: Fine-tune credentials with specific destination restrictions to prevent unauthorized fund transfers.
