An AI that arbitrages funding rates.

From Telegram tap to on-chain position, four steps.
Everything happens inside the Mini App. The chat only sends notifications; you never type a command.
Open in Telegram
Tap the Menu Button next to the chat field. No app store download, no browser extension, no wallet to install first.
Deposit USDC or USDT
From Ethereum, Solana, Base, Arbitrum, Polygon, BNB Chain, Optimism, Avalanche or Tron. Routed at cost.
AI trades the funding rate
Delta-neutral positions on Hyperliquid capture the funding payment between perpetuals and spot, not a directional bet.
Withdraw anytime
Your shares, your call. Withdrawal rights are never gated by membership status, even if it's lapsed.
Funding-rate arbitrage, not a directional bet.
Perpetual futures never expire, so exchanges charge an hourly funding payment to keep price tethered to spot. When longs outnumber shorts, funding turns positive, and longs pay shorts.
Arbii shorts the perpetual and holds an equal long spot position. The two price exposures cancel out, leaving the funding payment as the return, not a directional bet.
Not risk-free. Funding can flip sign, the two legs can diverge, and spot liquidity is the weakest point in the trade. Flat and losing months are normal. Read the risk disclosure.
Worked example · $10,000 deposit
- Deposit (USDC from Base)
- $10,000.00
- Routing, at cost
- -$35.00
- Credited to vault
- $9,965.00
- Trading (illustrative +10%, not a projection)
- $10,961.50
- Profit
- $996.50
- Performance fee (20% of profit only)
- -$199.30
- Routing + withdrawal fee (0.25%)
- -$77.80
- You receive
- $10,684.40
Illustrative only. The +10% result is a made-up number to show how fees are calculated, not a projection or promise of returns. Membership is billed separately.
We built it so we can't move your funds even if asked to.
"Non-custodial" gets used loosely across crypto. Here's what it means precisely for Arbii, and just as importantly, what it doesn't.
To be precise: custody and withdrawal rights are on-chain and verifiable. The strategy engine and wallet infrastructure are centralised systems we operate, not a claim of "fully decentralised." Full picture in our risk disclosure.
No seed phrase, ever
Your wallet is created inside the Mini App the very first time you open it. There's nothing to write down, and nothing to lose to a phishing page.
No exchange API key
Arbii never holds an API key that could move funds on an exchange. Positions are opened and closed directly on-chain, with no custodial account to compromise.
Signing happens on your device
A 6-digit passcode you set yourself derives your decryption key locally, unlocking your key share on-device. It never leaves it, and we never see it.
Every action is verifiable
Deposits, trades, fees and withdrawals all render with their transaction hash, linked to the block explorer. You check the chain, not a number in an app.
No track record yet. We'd rather tell you that than fake one.
Arbii hasn't gone live. Once the vault is trading, performance will be published as raw, verifiable on-chain history, not a chart we ask you to trust.
No backtest presented as a live result on this site. If there's nothing real to show yet, we say so.
Every trade, fee and payout will carry a transaction hash you can check directly on HyperEVM.
Flat and losing months are an expected feature of this strategy, not something we'll hide.
Historically, funding-rate arbitrage strategies of this shape have produced high-single-digit to roughly 20% annualised returns in normal conditions: stronger in high-funding regimes, close to zero when funding is flat. That's a description of the market this strategy trades, not a forecast or promise about your money.
Four fees. No hidden ones.
Network costs are shown separately from what we charge, at every step, before you confirm anything.
Annual is two months free compared to paying monthly. Required to deposit new capital, but withdrawals never require it.
No markup, ever, on deposits. Routing costs are shown as a plain network fee before you confirm anything at all.
Charged only on your own profit, using your cost basis. Capped at 30% forever, with 48 hours' notice of any change.
Always a percentage of the amount withdrawn, never a flat fee that could quietly eat a small withdrawal.
In a flat year, you pay membership and routing costs with no performance fee to offset them, because there's no profit to take 20% of. We'd rather you know that going in.
20% recurring, paid on-chain, no claim step.
Share your link. Every time someone you referred pays for membership, including renewals, your commission is paid atomically in the same on-chain transaction. No claim button, no payout queue.
- Single tier: no sub-affiliates, no MLM structure stacked underneath you.
- You see referral status, never their balances or activity. That stays private to them.
- Payment history is pulled from on-chain events: verifiable, not just trusted.
Referrer must be an approved, active paying member, checked on-chain. Self-referral is blocked at the contract level.
Straight answers, before you deposit.
What is Arbii, in one sentence?
A pooled trading vault on Hyperliquid that runs a delta-neutral funding-rate arbitrage strategy, opened and managed entirely from a Telegram Mini App. No browser wallet, no seed phrase.
Can Arbii's team move or freeze my funds?
No. Signing happens on your device, unlocked by your own passcode or biometrics. Our backend never holds the key material needed to authorise a withdrawal, so there's nothing for us to move or freeze.
Is this risk-free arbitrage?
No, and we won't pretend otherwise. Funding rates can flip, spot liquidity can be thin, and flat or losing months are a normal feature of this strategy. Read the full risk disclosure before depositing.
Can I withdraw whenever I want?
Yes. Withdrawals are never gated by your membership status. Even a lapsed membership keeps full withdrawal rights, always.
Do I need to already own crypto or a wallet?
No. Your wallet is created for you inside the Mini App the first time you open it. You'll still need USDC or USDT to deposit, from any of the supported chains.
Ready to put your capital to work?
Open Arbii in Telegram, set your passcode, and you're ready to deposit. No browser wallet, no seed phrase, no waiting on a form.
