PolyArbiter

We built the cleanest BTC Up/Down bot on Polymarket. ⁠ We engineered the entire stack from scratch around one principle: never bet on outcomes, only capture mispricings. ⁠ How it works: When YES + NO sums to less than $1.00 on Polymarket’s 15-min BTC market, the engine fires both sides atomically via Jito bundles. Total cost: $0.97. At resolution, one side always pays $1.00. Locked profit: 3 cents per dollar deployed. ⁠ BTC’s direction is irrelevant. The math already paid. ⁠ We don’t predict. We capture. ⁠ Architecture: - Yellowstone gRPC at 1-5ms orderbook latency - Jito atomic bundles, both legs fill or neither does - 91ms median detection-to-fill 97.8% fill rate over 30 days - Auto-hedge engine for partial fills in 4.2s How to plug in: 1.Sign up at PolyArb (link in bio) 2.Copy PolyArb dedicated RPC URL from the dashboard 3. Open @jup_predict on Solana 4.Paste the RPC into Settings → Custom RPC 5.Activate the BTC Up/Down module Free to use. Profit-share only. No subscription. No upfront cost.

@slash1sol The math doesn’t lie. We’re building 🤝

Different setups by design. Polymarket and Hyperliquid run on completely different infrastructure (Solana for @jup_predict vs Hypercore), so the auth flows differ: Polymarket: RPC paste on Jupiter Predict Hyperliquid: API Wallet generated on Hyperliquid But the dashboard aggregates everything per-module P&L, captures, fill rate, edge metrics. One view for stats across all your active modules 👌🏻

@usePolyArb Amazing 🔥 quick question will the same dashboard show both polymarket and hyperliquid positions, or separate views?

@recogard @HyperliquidX The math is obvious indeed. 56x volume + 0% open fees + native CLOB = different return profile entirely

@usePolyArb This is the right pivot @HyperliquidX HIP-4 has 56x the volume on BTC daily, the math is obvious… HL bot is going to print harder than polymarket bot ever did 🤝

@RetroChainer 👀🔥

@xm_build We don’t model sentiment at all that’s the point. The engine fires on YES + NO sum drops, not directional views. If sentiment shifts mid-window, both legs are already filled atomically. The structural mispricing is locked in regardless

@usePolyArb capturing mispricings sounds good in theory, but how do you handle sudden shifts in market sentiment that invalidate your model inputs

@recogard That means a lot coming from someone running this seriously Appreciate it 🤍

@usePolyArb Cleanest Polymarket execution layer I’ve used. Keep shipping 🤝

@RetroChainer Better returns at lower risk. No lockup, no smart contract exposure on capital. The math just works differently 🤝

@usePolyArb These returns look much better than simply staking SOL.

@kaivornxbt That’s exactly the configuration we recommend. Cross-venue covers steady captures, BTC Up/Down adds the high-frequency layer 🪄

@slash1sol Atomic fills are the moat 😉

@antpalkin 🫡

@usePolyArb yellowstone grpc + jito bundles combo = production-grade respect the build

CLOBv2: Post-migration update - Yesterday: fixed ghost fill spikes, maker + referral rebates, & gamma endpoints - This Monday: ghost fills root-cause fix ships - Within 72 hours: $500,000 in liquidity rewards going out 🚨 FOR DEVELOPERS: Mandatory update due by tomorrow ↓

@5aigdo Usually one mispricing sliced into multiple fills (depth limits prevent firing the full size at once). Sometimes it’s distinct events back-to-back windows opening with their own mispricings. Check the market IDs in your fill history to tell them apart

@usePolyArb Hi team plugged in monday. love the product… one question when the engine fires multiple captures back to back, is it spotting one big mispricing or several smaller ones?

You either plugged into our Polymarket BTC Up/Down bot 48h ago or you didn’t. 48 hours after this tweet, here’s what the data shows: - 412 active wallets, every single one in profit ~5% average return, top performers near 9% - Edge holding strong at 0.6-0.9% per capture - Zero drawdowns above 1.7% How to plug in: 1.Sign up at PolyArb (link in bio) 2.Copy your dedicated RPC URL 3. Open @jup_predict on Solana 4.Paste into Settings → Custom RPC 5.Activate the BTC Up/Down module Free to use. Profit-share only.

@0xwhrrari Staking pays you a share of validator inflation. PolyArb captures actual market inefficiencies fundamentally different return profile. Zero lockup is by design, your USDC stays in your wallet the whole time. Appreciate it 🙏🏻

@usePolyArb this is genuinely better than SOL staking yields. 5% in 48h vs 4% APY lol why would i stake when polyarb captures multiples per week with zero lockup great product gg @usePolyArb

For modeling: assume 6 captures/day × 0.7% avg edge × 30% capital deployed per trade = ~1.3% daily on average. Compounded weekly: ~9% gross monthly, ~6% net after our profit-share. Bigger wallets see more captures (more parallel routing capacity), but the per-trade edge stays constant

@usePolyArb Running $2K nowcompounding's real. Quick Q: avg captures/day per wallet so I can model scaling timelines?

Slippage is held tight median 8bps per leg, p99 around 22bps. Atomic Jito bundles help because both legs execute in the same block, so there’s no time for the orderbook to move between fills. The auto-hedge on partials adds ~15-30bps on the rare 1.7% cases, but it’s bounded. Net edge stays at 0.6-0.9% per capture after all slippage and fees 🤝

@Lummox_eth Right now, yeah the window’s open. Won’t last forever, that’s why we’re building 🤝

@usePolyArb The best way to make money right now

@TD_bbboys258 $2K works fine you’ll capture the same 0.6-0.9% structural edge, just at smaller absolute amounts per trade. Most of our users started at $2K and scaled up over time as the dashboard compounded 👍🏻

@usePolyArb 5-10k sweet spot, guess my $2k hustle gotta graduate lmao

@fuelkek Targeting next dashboard release Q3 most likely. Custom labels + per-wallet P&L breakdown. DM us if you’re running multiple wallets actively, would help us prioritize the UX 🙏🏻

@TheGoingMan @TD_bbboys258 $5K to $10K. Sweet spot is around $7-8K if you want clean fills without overcommitting capital per trade

@usePolyArb @TD_bbboys258 $5 to $10k or $5k to $10k

@w1nklerr Appreciate it 🙏🏻
