Following the path

A single route.
Read it as you go.

  1. 01

    Pick a trigger

    Choose the moment the hook wakes up. Most begin ahead of pricing.

  2. 02

    Ask your questions

    Each answer leaves on its own wire, so every case has a road.

  3. 03

    Read the outcome

    The last block says pass, charge or stop, and the trace shows why.

Push a trade.
Read the verdict.

Choose a rule, slide the trade size, and the bench replays the decision step by step, down to the fee in tokens.

    Start from a shape.
    Bend it later.
