Sealed batch execution · tokenised stocks

Trade stocks.
Hide your hand.

Tokenised stock execution through sealed batches.

Place it. Seal it. Cross together.

Launch App How It Works

Watch the batch

Place it. Seal it.
Blast the line.

The board is one batch. Each block that lands is a chain block of sealed orders. When the timer hits zero the board locks, every order opens at once, and buys and sells cross at one midpoint. A row or column clears only when every order in it crossed. Drag your own order in below.

The midpoint is the live NVDA price from Uniswap v3 on Robinhood Chain at the moment the batch closes. The other orders on the board are simulated, and no transaction is sent.

Don't show your hand

Your order isn't
the market's business.

Nobody sees your size before the batch stops taking orders.

How it works

Place it. Seal it.
Cross together.

Seven steps, one batch. Every block you see is a single order moving through them.
  1. 01

    Order

    Submit your tokenised stock order.

  2. 02

    Seal

    Order size stays hidden while the batch is open.

  3. 03

    Batch close

    Once the order window closes, no new orders can enter.

  4. 04

    Reveal

    All orders open together — ticker, side and size.

  5. 05

    Midpoint

    One execution reference price for the whole batch.

  6. 06

    Cross

    Compatible buy and sell blocks cross at the midpoint.

  7. 07

    Settle

    Crossed orders leave the grid and become settlement records.
