O3 withdrawal fees — FAQ
Which exchange has the cheapest O3 withdrawal fee?
MEXC on the Ethereum (ERC20) network, at Free O3. Withdrawal fees are flat amounts of O3, so the cost in USD moves with the market.
How much does it cost to withdraw O3?
Between $0.00 and $1.45 for the same coin, depending on the exchange and the network you pick. The network usually matters more than the exchange brand — the table above lists every route we have data for.
Which network is cheapest for sending O3?
O3 can be withdrawn over 3 networks; Ethereum (ERC20) is the most widely supported (5 exchanges). Always pick a network the receiving wallet or exchange also supports — funds sent over an unsupported network can be lost.
Are O3 deposit fees charged too?
Most exchanges accept crypto deposits for free — what you pay is the sending network's own transaction fee. The "Deposit fee" column shows a number only where the exchange explicitly publishes one.
Withdrawal and deposit fees are synced from each exchange’s official fee API or fee page (last sync 2026-08-29 00:53 UTC). USD values are computed at the live O3price, so they move with the market. “paused” means the exchange currently has withdrawals disabled on that network. Network names are normalised — exchanges spell the same chain many different ways.
