Rocket Money for agent wallets

Your agent accumulates approvals, bleeds micropayments, and concentrates risk across facilitators. Nobody checks the bot's wallet. StableShield does.

The problem

Three blind spots no tool catches

250K+ daily autonomous transactions across x402, MPP, and ACP. Every agent wallet accumulates invisible risk.

⚠

Approval exploit surface

$200M stolen in 2024 through forgotten approvals. You swap once, the permission stays forever. Attackers drain wallets through protocols you used months ago.

↻

Invisible autonomous spending

Agents paying for services they no longer need. x402 micropayments leave no approval trail. MPP session channels lock funds in escrow. No human monitors the burn.

⚖

Facilitator concentration

90% of volume through one facilitator. It goes down, all services break. The on-chain equivalent of all your autopays hitting before payday.

How it works

Scan. Score. Act.

Two scores, two action types, one prioritized report. Agent operators and wallet owners get the Rocket Money equivalent — not a data dump.

Scan

Approvals + transfers + MPP sessions across 6 chains. All ERC-20 + TIP-20 tokens. 90-day lookback.

Score

13 risk signals, 6-factor approval enrichment, Agent Burn Report with 15+ metrics including x402 and MPP burn.

Prioritize

Urgent / Recommended / Monitor actions. Each includes a contract address and estimated monthly savings.

Act

Gasless revocations via Smart Wallet. Close dormant MPP sessions. Every fix logged on-chain via ERC-8004.
