A bot that makes markets. A scanner that finds the carry.
Vesper runs on your own account and quotes both sides of the book. It never holds your funds and cannot withdraw them. The screener is the other door: funding rates across every perp venue we track, ranked by what a route really pays.
Vesper: the market-making bot
A market maker does not predict direction. It posts a bid and an ask, waits to be taken on one of them, and works the resulting inventory back to flat. The money is in turnover and in not being picked off, not in the spread on paper.
Vesper does this on your own exchange account. You approve a trade-only agent with one signature; it can place and cancel orders and nothing else. No deposit to us, no withdrawal path, revocable whenever you like. It is the same engine we run on our own accounts, not a demo built for the website.
- Quotes both sides and re-posts after every fill
- Inventory caps, a loss floor and a maker-first exit
- Modes tuned per venue, including Vulcan, calibrated on gold
- You keep custody: the key can trade, never move funds
Pick the mode, not the guesswork
Each venue behaves differently, so each gets its own preset rather than one setting stretched across all of them. Ondo trades perps on gold, US equities and indices; Perpl and RISEx are crypto perps; Entropy is its own market.
Delta-neutral modes go further: one account quotes while a second hedges the same second, so price exposure cancels and the funding spread is what remains.
- Market-making on Ondo, Perpl, RISEx, Arcus and Entropy
- Delta-neutral pairs across two venues or two accounts
- Vulcan: built for one market, gold, and calibrated on it
- Every mode documented, with what it does and when it fails
The funding screener, if that is what you came for
Perpetual futures pay funding between longs and shorts. When two venues disagree on the rate, the gap can be held delta-neutral. The screener ranks those routes live across DEX and CEX venues, and the backtester checks a route against history before it becomes a position.
- Live funding rates across DEX and CEX perp venues
- Routes ranked by carry, stability and entry gap
- Backtest a route over historical funding periods
- Arcus screener for perps on stocks, gold and indices
Questions
Does Vesper hold my funds?
No. You approve a trade-only agent on your own exchange account. It can place and cancel orders; it has no path to move or withdraw anything, and you can revoke it at any time.
What does a market-making bot earn?
Turnover, minus what it gives back. It is paid the maker side of the spread on every fill and loses when the market moves against inventory it is holding. The work is in holding less adverse inventory, not in posting wider quotes.
Which venues does Vesper run on?
Ondo, Perpl, RISEx, Arcus, Entropy and Hotstuff. Ondo carries perps on gold, US equities and indices; the others are crypto perps.
What is Vulcan?
A Vesper mode built for a single market and calibrated on it: gold on Ondo. It quotes a tick inside the touch for queue priority and leaves as a maker rather than paying for urgency. On other metals those levers are switched off, because there the arithmetic does not work.
What is funding arbitrage?
Perpetual futures pay a funding rate between longs and shorts. Holding a long on one venue and a short on another cancels price exposure and leaves the difference in funding as the return, as long as the spread survives fees and slippage.
Do I need to choose one or the other?
No. The screener finds carry routes you take yourself; Vesper runs a strategy on your account continuously. They answer different questions and share one account and one login.
