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

1. YC-backed — legitimate infrastructure with VC funding and active development
2. Multi-chain — works on Base (our primary chain), not limited to one chain
3. Skill, not a plugin — integrates as a skill doc guiding the agent, not a standalone tool
4. Evaluate alongside budget-service — our existing budget-service.ts already tracks per-operation costs; PaySponge adds execution (actual payments) on top
