Five stocks. One transaction.
Panier buys a whole basket of Robinhood Chain Stock Tokens at once: up to 8 stocks, your weights, one signature. Every leg is checked against Chainlink, and the basket sells back to USDG the same way.
Your own index, bought in one go.
Spreading $1,000 over five stocks on a usual swap page is five swaps, five approvals and five chances to fill off price. On Panier you set the weights and sign once: the contract buys every leg in the same transaction.
Each leg must land inside 1.5% of Chainlink or the whole basket reverts, so you never end up holding half of it. Selling works the same way: every stock back to USDG at once.
Usual swap page
Panier
Your band around the real price.
A usual swap only checks the pool against itself: if the pool is already off, you fill off. Panier reads Chainlink on chain and sets the minimum out from it, at the band you pick: 0.3%, 0.5%, 1% or 1.5%.
Pool inside the band: the trade fills. Pool outside: the whole transaction reverts and nothing moves.
Limits that fill at your price or better.
Place a buy under the market or a sell above it. The funds wait in the contract, not with a bot. When Chainlink reaches your price, a keeper fills it on the pool, and the contract checks the fill is no worse than your limit.
If the pool can't meet the limit yet, the order simply waits. Cancel any time, everything comes back.
TSLA to NVDA in one go.
On a usual swap page, rotating from one stock to another is two swaps through USDG, two approvals and twice the waiting. Panier sells and buys in the same transaction, both legs checked against Chainlink, the fee taken once.

Panier
One signature instead of an approval.
USDG and the Stock Tokens support permit. Panier takes the allowance as a signature inside the trade, for exactly the amount you trade, so the first trade of any token is one transaction and nothing is left approved forever.

Questions.
Where does the liquidity come from?
The Stock Tokens' own Uniswap v3 pools on Robinhood Chain. Panier routes through them and checks every fill against Chainlink.
What if markets are closed?
Stock feeds pause between sessions. The floor uses the last Chainlink price, so a pool that runs away over the weekend is refused.
What does it cost?
0.1% of the USDG side, plus the pool fee and gas. Orders add $0.05 for the keeper that fills them.
Is it audited?
No. The router is small and public, but unaudited. Size accordingly.
