Lobster.cash — Agent Payments

Lobster.cash enables the agent to spend money and make purchases.

What It Is

An OpenClaw plugin by Crossmint that gives AI agents payment capabilities:

• Solana USDC wallet for crypto payments
• Visa virtual cards for traditional purchases
• Agent can pay for APIs, services, subscriptions — anywhere credit cards or USDC are accepted
• Human approves scoped payment methods

Installation

openclaw plugins install @crossmint/lobster.cash

Then configure:

/flykeys set CROSSMINT_API_KEY your_key

When to Use

• User asks the agent to pay for something (API credits, subscriptions, services)
• Agent needs to autonomously pay for resources (hosting, data feeds)
• User wants to set up payment methods with spending controls
• User wants the agent to manage expenses

How It Works

1. Lobster.cash provides a custodial Solana USDC wallet for the agent
2. Virtual Visa cards can be created for specific merchants/categories
3. Human sets spending limits and approval policies
4. Agent requests payment → Lobster processes via USDC or Visa

Spending Controls

• Per-transaction limits ($X max per purchase)
• Daily/weekly/monthly caps
• Merchant category restrictions
• Domain allowlists for online purchases
• Human approval required above threshold

Integration with OpenClawnch

Lobster.cash complements our existing wallet infrastructure:

• Agent payments (Lobster) — for the agent to spend money on the user's behalf
• User DeFi (ClawnchConnect/Bankr) — for on-chain financial operations

They serve different purposes and can coexist.

Important Notes

1. Solana-based — Lobster uses Solana USDC, not Base/Ethereum
2. Custodial — Lobster holds the payment wallet (different from our non-custodial model)
3. Plugin, not a tool — installs as a separate OpenClaw plugin alongside our crypto extension
4. Evaluate vs PaySponge — Lobster for Visa cards, PaySponge for multi-chain crypto payments. Pick one or both.
