Gasless
UniswapX Dutch auction on Robinhood Chain. Fillers may expire the order unfilled. This is not a resting limit book, and it never wins the Swap button. Typical fill window is a few seconds. Size needs to be about $300+.
To prove a fill: sell about $350+ USDG for WETH, then watch filled vs expired below.

First try: sell a few USDG for WETH (not 🚀, not 0.001). Ophis solvers fill a min-out + expiry order. Typical batch ~24s. 1 bp + surplus share to Ophis. Never the Swap button.
