How to Buy XDB CHAIN
Every exchange we track that lists XDB, what the buy costs, and what it costs to take XDB with you afterwards.
5 of the exchanges we track list XDB, and 5 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 XDB and move it to your own wallet. XDB moves over 2 networks (XDB, XDB CHAIN) — pick the same one on the exchange withdrawal screen and in your wallet. 1 of them has XDB withdrawals paused right now — you can buy there, but you cannot take the coin with you until it reopens.

Where to buy XDB
All-in cost is the trading fee on a $1,000 market buy plus the cheapest fee that exchange charges to withdraw XDB. 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 XDB step by step
- Pick a venue from the table. For a coin this size the choice is usually short — 5 exchanges list XDB at all, and the table already shows what you will pay to leave as well as to buy.
- Fund the account. 5 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 XDB on the exchange is free but custodial. Moving it to a wallet that supports it costs one withdrawal fee — send a small test amount first, and match the network on both sides.
How to buy XDB — FAQ
Where can I buy XDB CHAIN?
On 5 exchanges we track: MEXC, Gate, Bitget, KuCoin, Bitrue. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw XDB.
What is the cheapest way to buy XDB?
MEXC, at $0.50 to buy $1,000 of XDB and withdraw it — $0.50 in trading fee plus $0.00 to move it out over XDB. 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 XDB with a credit card?
Indirectly, yes. 5 of the exchanges listing XDB accept a card, but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for XDB 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 XDB?
Every exchange charges one, as a flat amount of XDB per network rather than a percentage. We do not have a priced figure for all of the venues listing XDB yet — the XDB withdrawal fee page has whatever each exchange publishes.
Is it safe to leave XDB 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. For a trading balance, staying put is reasonable; for a long hold, most people move.
Which network should I use for XDB?
XDB is issued on 2 networks and they are not interchangeable — XDB sent over XDB will not arrive at an address on XDB CHAIN. XDB is the one most exchanges use (3 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 XDB 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.
