How to Buy Orbiter Finance (OBT)Every exchange we track that lists OBT, what the buy costs, and what it costs to take OBT with you afterwards.
12 of the exchanges we track list OBT, and 12 of those accept fiat, so you can buy it without holding crypto first. The cheapest place to place the order is MEXC at $0.50 on a $1,000 market buy. It is also the cheapest once the withdrawal fee is added — $0.50 to buy $1,000 of OBT and move it to your own wallet. OBT moves over 3 networks (Arbitrum One, Base, Ethereum (ERC20)) — pick the same one on the exchange withdrawal screen and in your wallet. 2 of them have OBT withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw OBT. 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.

Showing 1–12 of 12 exchanges listing OBT
On 12 exchanges we track: MEXC, Gate, CoinW, Bitunix, Biconomy.com and 7 more. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw OBT.
MEXC, at $0.50 to buy $1,000 of OBT and withdraw it — $0.50 in trading fee plus $0.004866 to move it out over Arbitrum One. 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%.
Indirectly, yes. 9 of the exchanges listing OBT accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for OBT on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Yes, and it is worth checking before you choose where to buy. It is a flat amount of OBT, set by each exchange per network, so it does not scale with the size of your purchase — the cheapest in the table is $0.004866 on MEXC. Our full OBT withdrawal fee table compares every exchange and every network.
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 $0.004866 for OBT. For a trading balance, staying put is reasonable; for a long hold, most people move.
OBT is issued on 3 networks and they are not interchangeable — OBT sent over Arbitrum One will not arrive at an address on Base. Arbitrum One is the one most exchanges use (9 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 OBT 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.
