PaySponge — Agent Financial Infrastructure
PaySponge (YC-backed) provides agent wallets, spending controls, and a gateway for businesses to sell to agents.
What It Is
Financial infrastructure purpose-built for AI agents:
- Agent wallets — fiat + crypto, multi-chain (Base, Solana, Tempo)
- Spending controls — per-operation cost limits, daily caps, domain allowlists
- Business gateway — standardized interface for merchants to accept agent payments
- OpenClaw skill available at
sponge.md
Setup
Add the PaySponge skill and configure:
/flykeys set PAYSPONGE_API_KEY your_key
When to Use
- Agent needs to pay for crypto-native services (API calls, data feeds, compute)
- User wants granular spending controls ($X/day, $Y/tx, domain restrictions)
- Agent needs a multi-chain wallet for programmatic payments
- User wants to set up autonomous spending for recurring costs
Spending Controls
PaySponge offers fine-grained spending policies:
| Control | Description |
|---|
| Per-tx limit | Maximum amount per single transaction |
| Daily cap | Maximum daily spend across all transactions |
| Domain allowlist | Only allow payments to specific domains/services |
| Category rules | Allow/block specific merchant categories |
| Asset restrictions | Limit which tokens the agent can spend |
| Approval threshold | Human approval required above $X |
Supported Chains
- Base (primary)
- Solana
- Tempo (Tempo Network)
Integration with OpenClawnch
PaySponge complements our existing infrastructure:
- DeFi operations (ClawnchConnect) — user-directed on-chain transactions
- Agent payments (PaySponge) — agent-initiated spending within budgets
- Budget tracking (budget-service) — our existing per-operation cost tracking integrates naturally
Lobster.cash vs PaySponge
| Feature | Lobster.cash | PaySponge |
|---|
| Visa cards | Yes | No |
| Crypto payments | Solana USDC | Base, Solana, Tempo |
| Spending controls | Basic limits | Granular policies |
| Merchant gateway | No | Yes |
| OpenClaw integration | Plugin | Skill |
Both can coexist: Lobster for Visa card payments, PaySponge for crypto-native payments with fine-grained controls.
Important Notes
- YC-backed — legitimate infrastructure with VC funding and active development
- Multi-chain — works on Base (our primary chain), not limited to one chain
- Skill, not a plugin — integrates as a skill doc guiding the agent, not a standalone tool
- Evaluate alongside budget-service — our existing
budget-service.ts already tracks per-operation costs; PaySponge adds execution (actual payments) on top
