Fell
Name your price.
Limit orders for tokenized stocks. Place a buy or sell order for NVIDIA, Apple, Tesla and 39 more at the price you choose. It waits on Robinhood Chain until someone takes it, and you can cancel it whenever you like.
A pool sets its price. An order sets yours.
On Uniswap you take the pool's price, less its fee and whatever your size moves it. Half the stocks on Robinhood Chain cost more than 0.34% to buy $1,000 of that way, and the dearest cost 1.28%.
You take what it gives
- The price is whatever the pool says at that moment.
- Every trade pays the pool's fee, up to 1% on thinner stocks.
- A larger order moves the price against you as it fills.
- You can't say "only if it gets to $180".
You say the price
- Sell only at or above your price, buy only at or below it.
- No pool fee and no Fell fee. You pay the price you set, plus gas.
- Your order stays in your wallet until the moment it fills.
- Cancel at any time with one transaction.
Three steps, all on chain
Fell builds each transaction and your wallet shows it to you before you sign. Settlement is done by Seaport 1.6, which OpenSea wrote and audited and which was already on Robinhood Chain before Fell existed.
Set a price
Pick a stock, the number of shares and your price. Fell shows what Uniswap would give you right now, so you know how far your price is from the market.
Publish it
One transaction records the order on Robinhood Chain through Seaport. Your shares or dollars stay in your wallet. Seaport only has permission to move them, and only on your terms.
Anyone can fill it
Anyone can take all of your order or any whole percent of it. Seaport swaps both sides in one transaction, or neither. Cancel whatever is left whenever you like.
Every stock, one book
The order book is Robinhood Chain itself: Fell reads it from Seaport's own records, so there's no server to trust and no server to go down. Prices from block 72,178,926; live figures load below.

What you are trusting
Fell adds no contract, holds no keys and cannot move anything of yours. Here's exactly what you rely on instead.
It fills when it is good for someone else
A sell order at $200 fills when $200 is a good price to pay, which is usually when the stock is at or above it. If the stock jumps to $260, someone can still buy from you at $200 until you cancel. Pick an expiry you'll actually watch.
Orders are public. Everyone can see your price, your size and your address.
Seaport, and the approval you give it
Placing an order approves Seaport 1.6 to move the shares or dollars that order offers, and nothing more. Seaport moves them only to settle a fill on the exact terms you published. You can lower the approval in your wallet at any time, which also stops the order.
Questions, answered
What does it cost?
Nothing to Fell. Placing an order is an approval and one Seaport transaction, and cancelling is one more. Gas on Robinhood Chain is usually a fraction of a cent. Whoever fills your order pays their own gas.
Where are my shares while the order is open?
In your wallet. Seaport pulls them only at the moment someone fills the order, and it delivers your USDG to you in the same transaction.
Who fills orders?
Anyone on Robinhood Chain: another Fell user, a trader who spots your price beating Uniswap, or a bot built for exactly that. Every open order is public in Seaport's records.
Can part of my order fill?
Yes, in whole percent. Every order is sized so that each 1% divides both sides exactly. Fell rounds your amounts down by a fraction of a cent to make that true, and shows you the exact numbers first.
What if nobody takes my price?
The order ends when it expires, and nothing moves. You can also cancel it before then. If you want to trade now instead, the app shows Uniswap's live price and can swap in one step.
What do I need to start?
A wallet such as MetaMask or Rabby on Robinhood Chain, a little ETH for gas, and either USDG to buy with or one of the 42 stock tokens to sell.
Is Fell audited?
Fell has no contract to audit. Settlement is Seaport 1.6, audited and used across Ethereum. The app's own code, the part that builds your order, is checked against the live chain on every release: 20/20 checks passing at block 71,626,500.
