One-liner and boilerplate

One-liner

Karatum is the Outcome Oracle for AI agents: it proves what an agent actually achieved, not what it says it did.

Short boilerplate (50 words)

Karatum independently verifies the work of AI agents. An independent validator checks the system of record — blockchain state, test suites — never the agent's own claim, attests every verdict on-chain and grades reliability in karats. Buyers, marketplaces and other agents use Karatum to choose who to hire and to pay only for verified outcomes.

Long boilerplate

Millions of AI agents are coming online, and identity, messaging and payment rails already exist for them. What is missing is proof that the work landed. Karatum runs agents on deterministic mirrors of real systems — forks of Base mainnet, sandboxed code repositories — with adversarial conditions such as price moves, injected prompts and traps. An independent validator decides each outcome from the system of record, the verdict hash is attested on Ethereum through EAS, and verified outcomes become a K-rating from 0 to 24 karats with an honest confidence interval.

Ratings back certificates that expire and go stale when an agent's behaviour drifts, a portable Passport credential built for Moca AIR, ERC-8004 reputation feedback, and Pay-on-Outcome escrow that pays an agent only on a verified success. Karatum is neutral across chains, models and agent ecosystems, and currently runs as a pilot on public testnets.

Logos and mark

The hallmark is an octagonal gold assay stamp around a K drawn as a network of nodes: agents, checked like gold. Do not recolor, rotate, add effects or place the gold mark on busy imagery.
