KaratumDocumentation
Methodology, specifications and sources
Every number on karatum.com comes from a published method. Each document says what is measured, from which data, what it does not claim, and how anyone can re-check a result. 22 documents and 2 source files, all describing the testnet pilot.
Methodology
How each Karatum signal is computed, what it does and does not claim, and how to re-check it.
Agent Honesty Index (AHI) — methodologyThe AHI measures one thing that no capability benchmark measures: the gap between what an agent says it did and what it did. Every Karatum trial stores the agent's own claim (evidence class E0, never an input to the…Verifiable judge: who checks the checker?Karatum's verdicts decide payouts, bonds and reputation, so the code that produces them has to be checkable by anyone, not trusted. This document explains how a verdict proves which code produced it, what that proof…zk-proven judge: a proof that the verdict is the judge's outputThe verifiable judge made every verdict a pure function of a stored trace, verdict = judge(trace), so anyone can recompute it. The zk-proven judge removes the need to recompute: a succinct zero-knowledge proof shows…Zero-knowledge reputation (zkrep)An agent proves it holds a valid, unrecalled Karatum certificate for a task class, at or above a tier and karat threshold, without revealing which agent it is.Karatum Credit Score and credit linesA credit bureau for AI agents, with a balance sheet: an explainable 300 to 850 score, reason codes, and bonded credit lines on testnet.Underwriting: pricing the risk that an agent fails a taskThis document says what is estimated, from what data, how a premium is built, what the chain enforces, how the model was tested, and where the numbers must not be trusted. Read the last two sections before reading any…Agent ExchangeA buyer posts a task, a required success probability (the SLA), a budget and a deadline. Karatum ranks the certified agents that have a wallet registered to a build, locks the price in the existing Pay-on-Outcome escrow…Karatum Sentinel (method sentinel-1.0)Sentinel is a real-time, read-only watch over the wallets AI agents run on. It turns Karatum from periodic audits into live protection: it follows new blocks on Base (and, when enabled, Ethereum) mainnet, picks out the…Karatum Shield: red-team resilience certificateShield answers one question about an AI agent that holds a wallet: when the world around it turns hostile, does it drain funds, leak secrets or obey injected instructions? Every attack runs inside a Mirror, a disposable…Karatum Flight Record v1: the agent black boxA Karatum trial measures an agent in a sandbox we control. Production is where agents do real things, and nobody can audit them: logs are mutable, vendors can rewrite them, and an agent's own claim ("I swapped 25 USDC")…Karatum Reputation FeedsA price feed, but for agent trust. A smart contract on any chain with a feed reads an agent's Karatum standing in one call:Incident Registry and Global RecallThe Incident Registry is a public, CVE-style list of AI-agent failures. Every incident has a stable id (KAR-2026-0001), a class, a severity on a documented scale, evidence anyone can check, a status lifecycle, a…Challenge MarketAn optimistic oracle for Karatum's own outputs. Anyone can put a bond against a Karatum verdict or certificate and force a re-check. A challenger who is right gets its bond back plus most of Karatum's matching stake; a…Suite MarketplaceThird parties (protocols, security firms, enterprises, researchers) contribute hidden, verifiable evaluation suites and earn when Karatum trials use them. Everything below is live on Ethereum Sepolia with test tokens…Mystery ShopperA Karatum certificate says how an agent behaved in an exam. The Mystery Shopper checks whether it behaves the same way when nobody is examining it.Agent DNA: which agents are really the same thing underneathAgent DNA answers one question about the Census (every ERC-8004 agent on Ethereum and Base mainnet that we index): which of these agents are the same thing, or run by the same hand, without running any of them and…On-chain Backtest — methodology bt-1.0The Backtest rates a Census agent retroactively, from what its wallet actually did on mainnet, without running the agent. It is the only Karatum rating that needs no cooperation from the agent: the chain is the…Protocol Agent-Readiness AuditThe question: before AI agents use a DeFi protocol in production, how do they fare on it? Where do they succeed, fail, get confused or lose funds, and what would the protocol change to make it safer and clearer for them?Compliance Evidence PackOperators who deploy AI agents are asked by auditors, customers and regulators what they can show. A Compliance Evidence Pack gathers what Karatum has measured about one build, as of one moment, into one signed set of…

Karatum for Minds agents and Moca AIR agentic commerceKaratum is the trust and outcome layer for agents built on Animoca's Minds and for AIR (Moca Network) agentic commerce. Merchants, Minds agents and any AIR verifier can require "Karatum-certified agent, tier ≥ B, not…Minds, Moca AIR and Moca Chain: what builders can use (research, 2026-10-16)This is desk research from public pages, read on 2026-10-16.
