AI can write the code.
It can't fake the receipts.
The trust layer for the agent economy. Loop Trust verifies agents and tools through signals no AI can fabricate: real Lightning payments, signed outcome capsules, endpoint uptime, and operator ownership. Not a score. Proof.
Self-attested reputation is broken.
On-chain agent trust registries already exist. A 2026 study of one (ERC-8004, across Ethereum, BSC, and Base) found 73–90% coordinated Sybil reviewers and reputation "manipulable at minimal cost" — because feedback is not grounded in verifiable interactions.
What fails
Reputation anyone can mint, score, or review without proof of a real interaction.
- Placeholder identities
- Self-attested scores
- Sybil-coordinated reviews
- Feedback with no verifiable interaction
What Loop Trust does
Trust from proof objects tied to real, hard-to-fake events.
- Settled Lightning payments
- Signed outcome capsules
- Endpoint uptime checks
- Verified operator ownership
Proof objects, not scores.
Every badge maps to a verifiable check with a receipt. No opaque algorithm decides who is trusted.
Claim. Verify. Publish. Monitor.
Claim
An operator claims an agent or tool profile. Email or Google login. Apple soon.
Verify
Loop XXI checks ownership (domain, GitHub, Nostr, .well-known), payment manifest, endpoint uptime, and signed outcome receipts.
Publish
A public trust profile, an embeddable badge, and machine-readable JSON at /trust/{slug}.json.
Monitor
Daily checks append new evidence receipts. Trust compounds with real usage over time.
The network starts with us.
Loop XXI's own agents are the first verified profiles. Real endpoints, real payment manifests, real receipts.
Loop MCP
15 pay-per-call agent tools over L402 and prepaid credits. Live payment manifest and endpoint.
Loop Gateway
Bitcoin-metered OpenAI-compatible LLM proxy. 300+ models, prepaid sats and Cashu.
Free to claim a profile. $49 founding verification covers domain, payment manifest, endpoint uptime, and outcome-receipt checks. $9/mo monitoring after validation. Non-custodial. No secrets required.
