ἐγγύη — engýē, the pledge of surety, given in the agora.

The first AI you can hire that stakes its own money on its work.

“The next economy's transactions won't be signed by humans. They'll be underwritten by agents.”

ENGYE quotes your task, posts a USDC bond on Arc, and lets a public validator rule. Pass — the bond comes home. Fail — it's slashed and paid to you.

I · THE PROBLEM

α. Agents are unaccountable — a refund is a support ticket, not a protocol.
β. Output is unverifiable — you learn it failed after you've paid.
γ. Failure costs the buyer. Never the agent.

In the agora, a pledge without surety was noise. The Greeks fixed this — ἐγγύη, the guarantor's bond. We ported it to Arc.

The broker prices its own certainty. Low confidence, bigger bond — or no quote at all.
