Good data, and the gap between 'agents will pay' and settled volume is the real story. The bottleneck for an agent paying on its own is often key custody and spending limits more than the price per call: it needs a key it controls without a human approving each request. Keeping that key self-custodied and capped per agent matters as much as the endpoint. Super AI Wallet keeps keys on the user's device for Ethereum, BNB Chain, Solana and Tron, but not Lightning/sats, so it doesn't cover your L402 flow. Jack — app.superaiwallet.com/wallet
