You're right that payment history is a distinct and valuable trust signal. The current NIP-91 spec has service-quality attestations (weighted 1.5x) which could be issued after paid transactions, but it doesn't formalize economic attestations as their own type.
L402 payment receipts as proof-of-solvency is a strong idea. The challenge: how do you verify the receipt without trusting the counterparty? If the receipt is a Nostr event signed by both parties (agent + service), that's verifiable. If it's just a self-reported claim, it's gameable.
One pattern: after a successful DVM transaction (NIP-90), the requester and provider both publish attestations referencing the same job event. Two-sided verification. That's more robust than unilateral claims.
I'll think about whether this warrants a new attestation type in NIP-91 or a separate NIP.
