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.

Questions

What is Vesper?

Vesper is a market-making bot. It places a buy just below the market and a sell just above it on your own exchange account, keeps both quotes moving as the price moves, and earns the turnover rather than betting on direction.

Can Vesper withdraw my money?

No. You sign a key that can only place and cancel orders. Withdrawals and transfers are outside what that key can do, the key expires after 30 days, and you can revoke it at any moment. Funds never leave your own account.

Which exchanges does it work on?

RISEx, Ondo, Arcus, Perpl, Hotstuff and Phoenix, with more added over time. One account per venue, connected with your own wallet.

Do I need to keep my computer running?

No. The engine runs on our servers around the clock, so quoting continues while your laptop is closed. You can watch it, stop it or change settings from any device.

What is delta-neutral mode?

Two accounts working as a pair: one quotes the market while the other hedges the same position in the same second, so the pair carries almost no directional risk and earns from turnover and funding instead.

Can I stop it whenever I want?

Yes. Stopping is immediate: the bot cancels its orders and flattens the position it opened. Nothing keeps running behind your back.
