Everyone chips in.
They get the shares.
Open a pot for a birthday, a graduation or a new baby. Friends add dollars from their own wallets, and when the pot closes one contract buys up to six tokenized stocks on Uniswap and sends them straight to the person you're celebrating.
- No owner, no fee
- Full refund if it's cancelled
- Guarded by a 30-minute price
One link, many wallets, one bunch of shares
Nobody hands their money to the organiser. The pot is a contract on Robinhood Chain, and it can only do five things.
Open a pot
Pick up to 6 stocks and how much of the pot each gets, the recipient's wallet, a deadline and, if you like, a goal.
Share the link
The pot's page is the invitation. Anyone with a wallet on Robinhood Chain can chip in USDG and leave a short note.
Watch it fill
Every contribution is on chain: who gave, how much and what they wrote. The page reads it straight from the contract.
Close it
The organiser closes it any time; after the deadline anyone can. The contract buys every stock and the shares land in the recipient's wallet in the same transaction.

Built so nobody has to be trusted
Not the organiser, not the person who closes it, and not us.
No keys at all
No owner, no fee, no upgrade, no pause. The contract does five things — open, chip in, close, cancel, refund — and nobody can change that.
Exact refunds
If the organiser cancels, or nobody closes the pot within 30 days of its deadline, every contributor takes back exactly what they put in. To the cent.
Sandwich-proof close
Whoever closes a pot must name a minimum for every stock, and the contract refuses any minimum below the pool's 30-minute average price, less the pot's slippage limit.
Straight to the recipient
The swap's recipient is fixed when the pot opens. The shares never pass through the organiser, the closer or the contract.
Tested on the live chain
10/10 properties (525 checks), a 8-seed fuzz and a sabotage sweep that caught 31/31 planted bugs, all run against Robinhood Chain's real pools. The numbers.
Deployed by its first user
Its address is fixed in advance by its code. We hold no key: the first person to open a pot deploys it, and anyone can check it is exactly this code.
Good to know
What does the recipient have to do?
Nothing. They need a wallet address on Robinhood Chain; the shares arrive there when the pot closes. They don't need ETH or USDG.
What can go in a pot?
Any of the 39 Robinhood stock tokens whose USDG pool on Uniswap keeps 30 minutes of price history (the guard needs it) — NVIDIA, Apple, SpaceX, the S&P 500 and more. Up to 6 in one pot, in any proportions.
What if the price moves before the pot closes?
The pot holds dollars until it closes, so the recipient gets whatever those dollars buy at that moment. The close itself is protected: each stock must fill at no worse than the organiser's slippage limit under the 30-minute average.
Who pays for gas?
Everyone pays their own, in ETH on Robinhood Chain: the organiser to open, each friend to approve and chip in, whoever closes it to buy the shares. Fees on this chain are a fraction of a cent.
What if nobody closes it?
After the deadline anyone can close it and the shares still go to the recipient. If 30 days pass after the deadline without a close, anyone can cancel it and every contributor can take their money back.
Is it audited?
No. The contract is 10,884 bytes, builds only on Uniswap and USDG, and is tested against the live chain, but it has not had a professional audit. Chip in what you would be comfortable gifting.
