How to Buy OmniCat (OMNI)
Every exchange we track that lists OMNI, what the buy costs, and what it costs to take OMNI with you afterwards.
6 of the exchanges we track list OMNI, and 6 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is Bitfinex at $0.00 on a $1,000 market buy. It is also the cheapest once the withdrawal fee is added — $0.00 to buy $1,000 of OMNI and move it to your own wallet. OMNI moves over 3 networks (Ethereum (ERC20), Omni Layer, Solana) — pick the same one on the exchange withdrawal screen and in your wallet. 2 of them have OMNI withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy OMNI
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw OMNI. It is the number the exchange’s own “how to buy” page never shows you, and it reorders the table more often than not. The coins column is how many assets each exchange lists in total, from our own sync — not the figure CoinMarketCap prints.

Buying OMNI step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 6 exchanges list OMNI at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 6 of those exchanges take fiat, 5 of them by card. Card is fastest and dearest; a bank transfer costs a fraction of it. Depositing a stablecoin you already hold is free on almost every exchange here.
- Place the order. A market order pays the taker fee in the table; a limit order that rests on the book pays the lower maker fee. On a thinly traded coin the spread costs more than either, so a limit order is worth the wait.
- Decide whether to move it. Leaving OMNI on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee, from $0.0₅6948 — send a small test amount first, and match the network on both sides.
How to buy OMNI — FAQ
Where can I buy OmniCat (OMNI)?
On 6 exchanges we track: Bitget, Bitfinex, CoinW, Kraken, OrangeX and 1 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw OMNI.
What is the cheapest way to buy OMNI?
Bitfinex, at $0.00 to buy $1,000 of OMNI and withdraw it — $0.00 in trading fee plus $0.0₅6948 to move it out over Omni Layer. If you are leaving the coin on the exchange, only the first half applies and a different venue may win. Paying by card adds the card processor's charge on top of both, typically 1.8–4%.
Can I buy OMNI with a credit card?
Indirectly, yes. 5 of the exchanges listing OMNI accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for OMNI on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Do I have to pay a fee to withdraw OMNI?
Yes, and it is worth checking before you choose where to buy. It is a flat amount of OMNI, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.0₅6948 on Bitfinex. Our full OMNI withdrawal fee table compares every exchange and every network.
Is it safe to leave OMNI on the exchange?
It is a custody choice, not a safety switch. While the coin sits there the exchange holds the keys: convenient, recoverable if you lose your password, and dependent on the exchange staying solvent and keeping withdrawals open. Moving it to a wallet you control removes that dependency and costs one withdrawal fee — from $0.0₅6948 for OMNI. For a trading balance, staying put is reasonable; for a long hold, most people move.
Which network should I use for OMNI?
OMNI is issued on 3 networks and they are not interchangeable — OMNI sent over Ethereum (ERC20) will not arrive at an address on Omni Layer. Ethereum (ERC20) is the one most exchanges use (2 of them). Withdrawal fees differ per network too, sometimes by an order of magnitude, so the cheapest network is worth checking as well as the cheapest exchange.
Exchange coverage for OMNI comes from each exchange’s own deposit and withdrawal endpoints (last sync 2026-08-29 00:53 UTC); trading fees are the published base tier, no volume discount applied (verified 2026-08-28). Exchanges we have a referral arrangement with appear first and are tagged as such — it changes no number in any row. Nothing here is investment advice; see our methodology.
