ARBIO.DECK · SEP 2026 · ROBINHOOD CHAIN

Every Stock,
One Price.

Flash arbitrage for Robinhood stock tokens. One transaction closes the gap between a stock's pools. No capital. Profit or revert.

THE PROBLEM

The Same Stock Trades At Several Prices At Once.

Many.Pools
Each stock token trades against USDG and WETH, at up to four fee tiers. NVDA alone has 5 pools.
No.One.Watching
Closing a gap by hand takes capital, several transactions and a bot that watches all day. So mostly nobody does.
So.They.Drift
Buyers in one pool pay more than sellers in another receive. Every gap is a worse price for someone.

Pool scan of Sep 18, 2026: 49 stocks trading in 136 pools. Slide 3 reads them live.

THE ENGINE

One Flash Cycle Closes The Gap.

Pool.A cheap
Sends the stock first. The engine owes it USDG until the end of the transaction.
stock
Engine
Sells the stock in pool B, where it is rich, inside pool A's callback.
USDG
Repay.Split
Pool A is repaid exactly. What is left is profit: 90% to you, 10% to the treasury.

QUOTES

Quoted Exactly, Before Anyone Signs.

Real.Swaps
quote runs the whole cycle against live pool state, then reverts before paying. Nothing changes on chain.
Every.Size
quoteMany prices a grid of sizes in one call. The app refines around the best one.
On.Chain
The deployed engine answers every quote itself, so the numbers on the page are the numbers a cycle would run.

A quote is exact for the block it reads. The minProfit guard covers the blocks in between.

Arbio06 / 12
FEES

10% Of Profit. Nothing On A Loss.

Protocol
10%

of each cycle's profit, never of its size

Caller
90%

to you, in the same transaction

Hard.Cap
20%

the most the code allows, ever

Capital
$0

needed. Gas only.

Pool fees (0.01, 0.05, 0.30 and 1.00%) go to each pool's liquidity providers and are inside every quote. A cycle that loses reverts, so there is nothing to take a fee from.

WHY ROBINHOOD CHAIN

Where The Stock Tokens Live.

Stock.Tokens
Robinhood's stock tokens live on its own chain. One runtime code hash identifies every real one.
Many.Pools
USDG and WETH pools at four fee tiers: many prices per stock, many gaps.
Fast.Blocks
Arbitrum Nitro, a block about every 0.1 seconds. A gap can close within a second.
Cheap.Gas
A cycle costs a few cents of gas, so small gaps are worth closing.

ROADMAP

More Hands, More Pools, More Quotes.

Keepersnow
The keeper script ships with the engine. Next: more people running it, so gaps close sooner.
V4.Poolsnext
Routes through Uniswap v4 pools as stock liquidity moves there.
More.Quotesnext
Cycles that start in more tokens than USDG and WETH.

A direction, not a schedule. No dates until they are real.
