~786% APR That's how a builder utilised random funding arb spikes on Korean equities via his bot, built on VOOI API/MCP (how to run it - below) And it's not even the most fun part of it At the weekend: → funding rates became more one-sided → the spread between venues widens → the opportunity goes up, and so does the noise Builder's stack was: → Long SAMSUNGUSD on @Lighter_xyz → Short xyz:SMSN via @tradexyz on @HyperliquidX → VOOI's Perps API/MCP - equities, RWA and crypto live funding rates, spread history, and position data scanner and executor What did his bot do: 1 → Flagged Samsung with 81% net APR, spread persistent enough across venues to be worth the friction 2 → Entered both legs simultaneously 3 → In 2h funding flipped to −550% APR but bot didn't close. It already covered its friction cost, short-term inversions were just noise 4 → Held arb for 23 hours while the spread churned, then rate hit 3,669% APR. mark-to-market still slightly negative at that moment (basis drift between venues). bot didn't exit at the peak. just kept collecting 5 → It detected APR declining 7 cycles straight (the smart_neg rule), read the wave dying, closed both legs automatically in under 10 seconds Realised APR was +402% What did the builder do manually? Just watched. That's pretty much it Bot found the entry, it sized and placed both legs, held through the -550% dip, collected through the 3,669% peak, and closed itself on the way down It's the programmable economy Find the bot setup on GitHub, educational purposes only: github.com/vooi-app/vooi-…
