Your wallet, read-only first.
You connect the wallet you already use. At this point Vesper can see the account and nothing else — nothing is signed, nothing can move.
One signature. Trade-only.
It hands Vesper a key that can place and cancel orders and can never withdraw. It expires in 30 days, and you can revoke it whenever you like.
It sits on both sides.
A buy just below the price, a sell just above it. Vesper keeps them there, moving them as the market moves — all day, without you.
Someone takes it. It re-posts.
The moment a quote is hit, the fill lands on the tape and Vesper puts a fresh one back on that side. That is the whole job, repeated all day.
Net position, back to zero.
Every fill is hedged at once, so you are not betting on direction. Price goes wherever it wants — your position stays flat.
