Real-world markets, 24/7
The S&P 500, gold, SanDisk and the Nasdaq 100 as perpetuals that never close. Start with the S&P 500: our most efficient market.
Vesper never withdraws
Vesper only places and cancels orders. Your funds never leave your QFEX account through Vesper.
One signature to connect
Sign in to QFEX with your wallet? One free signature and Vesper gets its trading key. Nothing to copy.
Put USDC on QFEX
Vesper trades your own QFEX account, so the money goes there first. Open qfex.com, sign in and deposit USDC on Arbitrum.
- Minimum$20 of margin is enough to start: at 2× that is $40 of buying power.
- Good start$50–200. You choose how much Vesper may use in the next steps.
