From a connected wallet to a filled block, in under a minute.
Six steps: connect, post, sealed commits, reveal, settle, refund. Nothing is sent to a chain; every number is what the contract would produce. Space pauses, arrow keys step.

Reads come from the public RPC; every write is calldata your wallet signs. RAIL has no server key.
Approve, then post. Later, settle if you want it done now. That is the taker's whole surface.
Commit a hash with a bond, reveal with the salt, fund the deposit. Re-quote free while the seal is open.
Read a price before reveal, move escrow anywhere but back to its owner or into a fill, or trap a deposit.
Change the inputs. The outcome follows.
The taker posts a SELL block.
Choose how many NVDA to sell and the lowest price you would accept. The desk pulls the full amount into escrow. A BUY block would escrow USDG instead.
Bond = 0.50% of the limit notional, floored at 25 USDG. Cancel is free until the first commit.
