Every exchange we track that lists RDN, what the buy costs, and what it costs to take RDN with you afterwards.
3 of the exchanges we track list RDN, and 3 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. Every exchange sends RDN over Ethereum (ERC20), so there is no network to get wrong. 2 of them have RDN 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 RDN. 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 1–3 of 3 exchanges listing RDN
On 3 exchanges we track: MEXC, Binance, KuCoin. The table above has each one with its trading fee, the payment methods it takes and what it charges to withdraw RDN.
We cannot rank the exchanges on cost for RDN yet: the venues that list it have not published enough of their fee schedule for a like-for-like comparison. The withdrawal fees in the table are still exact.
Indirectly, yes. 3 of the exchanges listing RDN accept a card (MEXC, Binance, KuCoin), but the card almost always buys a major asset — USDT, USDC, BTC — which you then swap for RDN on the same exchange. That means two fees: the card charge, then the trading fee in the table.
Every exchange charges one, as a flat amount of RDN per network rather than a percentage. We do not have a priced figure for all of the venues listing RDN yet — the RDN withdrawal fee page has whatever each exchange publishes.
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.
Exchange coverage for RDN 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.
