Themis.

the trade tribunal

Every trade deserves
due process.

State your intent in plain words. An advocate argues it, a skeptic prosecutes it, and a judge rules on live market evidence — then the verdict is hash-sealed before execution, so the record can never be rewritten.

The doctrine.

I

The motion

Your words become a structured intent — side, symbol, size. No forms, no tickets. The agent reads what you mean.

II

The tribunal

Advocate and skeptic argue from the same live evidence — price, trend, RSI, volatility. The judge weighs it and rules: approve, revise, or reject.

III

The seal

The full verdict is keccak256-committed the instant it is issued — before any fill. Anyone can recompute the hash. Doctored records don't verify.

Verdicts as a service.
