Quick Start Guide

How to use the DFBA Auction Simulator

1

Pick a Scenario

Choose from the Scenarios tab on the left — each one demonstrates a different DFBA concept like front-running, sandwich attacks, or price discovery.

2

Run the Batch

Hit Run Batch Now or let the timer auto-fire. Watch the Bid Auction and Ask Auction lanes clear with prices and matched volume.

3

See the Graph & Explanation

After the batch fires, a Supply & Demand chart shows where the clearing price emerged. Expand What Happened? for a detailed walkthrough of the scenario, the DFBA result, and the key takeaway.

4

Compare with CLOB

In Scenarios mode, a CLOB comparison runs automatically — you'll see a side-by-side breakdown showing how DFBA delivers better, fairer outcomes than a traditional order book.

You can also try Auto Demo in the top bar for a continuous live feed, or switch to Manual to place your own orders.

How DFBA Works

1Orders accumulate during the batch window
2Bid Auction: Maker BUYs are matched against Taker SELLs at a single uniform price
3Ask Auction: Maker SELLs are matched against Taker BUYs at a single uniform price
4Clearing price = midpoint of the crossing range (equal improvement for both sides)
5Excess volume is allocated pro-rata — no time priority, no MEV
