How to Buy Cosmos Hub (ATOM)
Trade a ATOM perpetual on Hyperliquid via Fexr in three steps. Self-custody, no KYC in eligible regions, AI-assisted execution.
Get a Wallet
Download the Fexr wallet app (iOS or Android) or connect any EVM-compatible wallet — MetaMask, Ledger, Tangem. Set a spending cap: this is the maximum Fexr can ever use on your behalf.
- App Store: Fexr Wallet for iOS
- Google Play: Fexr Wallet for Android
- Or connect via WalletConnect from any EVM wallet
Fund with USDC
Deposit USDC to your Fexr account via Arbitrum. USDC bridges to Hyperliquid automatically — typically 1–3 minutes.
- Already have USDC on another chain? Bridge to Arbitrum via Arbitrum Bridge
- Need to buy USDC with fiat? Use a CEX (Coinbase, Binance) then transfer to Arbitrum
- Minimum deposit: $10 USDC
Open a ATOM position
Tell the Fexr AI assistant what you want: "Buy $100 of ATOM at market." The assistant shows you the position and fee before you confirm.
- Market orders fill straight away, close to the current price, or cancel
- Recurring buys: a fixed amount on a schedule, inside your spending cap
Buying Cosmos Hub — Common Questions
01. What is the minimum amount to buy ATOM?
$10 per order. That's Hyperliquid's minimum order value, and Fexr checks it before the order is sent.
02. Do I need to verify my identity (KYC)?
No KYC required for eligible regions. Fexr is self-custody — you hold your own keys. Geographic restrictions apply (USA, UK retail, Ontario, Belgium, OFAC territories).
03. What fees apply when buying ATOM?
Trading ATOM: Hyperliquid's trading fee plus a small Fexr fee. Depositing USDC over Arbitrum costs well under a cent in gas.
04. Can I withdraw my ATOM?
Perpetual positions settle in USDC. Withdraw USDC via Arbitrum to your own wallet. Withdrawals always return to your own wallet — Fexr cannot send funds to third parties.
05. Is buying ATOM on Fexr safe?
Your funds stay in your own wallet. Fexr holds a capped, revocable trading permission — not custody of your assets. You can revoke it anytime.
