What is the minimum deposit amount on OKX? Minimum limits for each currency
There is no universal minimum deposit amount on OKX. It depends on which cryptocurrency you deposit, which network you use, and whether you are depositing fiat or crypto. For cryptocurrency deposits, the minimum limit is shown separately for each coin and network on the "Assets – Deposit" page. For fiat deposits, the minimum is usually around €1 or R$10.

Step 1: Determine whether you are depositing "crypto" or "fiat"
The limit rules for these two deposit types are completely different. Identify which one applies to you.
Cryptocurrency deposits (transferring BTC, ETH, USDT, etc. from an external wallet):
There is no single minimum amount. Each coin + network pair has its own limit.
Go to Assets – Deposit, select the coin and network, and check the "Minimum deposit" shown on the page.
Limits vary significantly between coins. For example, USDT (ERC-20/TRC-20) usually requires at least 1 USDT, while BTC may require more than 0.00001 BTC on some networks.
Fiat deposits (depositing fiat directly via bank transfer, Pix, PayNow, etc.):
Each payment method has a clear minimum amount determined by the channel itself.
OKX official data shows: EUR via SEPA min €1, BRL via Pix min R$10, USD via bank transfer min $3.01, AUD bank transfer min A$0.01, SGD PayNow min S$0.01.
Confirm whether your deposit type is crypto or fiat, and then follow the corresponding step below.
Step 2: Cryptocurrency – check the real-time minimum limit in the app
This is the most accurate method, because the minimum limit can differ depending on the network even for the same coin.
On the app:
Open the OKX app and tap Assets at the bottom of the home screen.
Select Deposit, then search for the coin you want to deposit (e.g., USDT).
Choose the corresponding network (such as TRC-20 or ERC-20).
The page will directly display the "Minimum deposit" for that coin on that network.
On the web:
Log in to the OKX website, click Asset Management in the upper right, then Deposit.
Search for the coin and select the network.
On the same page you will see the "Minimum deposit".
What if the amount is below the minimum limit: OKX explicitly states that if the amount is lower than the minimum displayed on the page, the funds will not be credited and cannot be returned.
Simply find the specific minimum deposit amount on the page for the coin and network you intend to use.
Step 3: Fiat – minimum limit reference for different channels
The minimum limit for fiat deposits is determined by the payment channel you select and varies significantly by region and currency.
| Fiat currency | Payment method | Minimum deposit amount |
|---|---|---|
| EUR (Euro) | SEPA bank transfer | €1 |
| EUR (Euro) | iDEAL | €1 |
| BRL (Brazilian Real) | Pix | R$10 |
| USD (US Dollar) | Bank transfer | $3.01 |
| SGD (Singapore Dollar) | PayNow | S$0.01 |
| AUD (Australian Dollar) | Bank transfer | A$0.01 |
| AED (UAE Dirham) | Bank transfer | AED 1 |

Specific fiat deposit limits are also affected by your KYC verification level – unverified or lower-level accounts have lower daily/monthly cumulative limits. Completing Lv.2 verification can significantly increase these limits.
Check the supported payment methods in your region and their corresponding minimum deposit amounts.
Step 4: Understand why minimum limits exist
OKX sets minimum deposit limits based on three main considerations:
On-chain economics: The miner fees for a very small deposit may exceed the deposit amount itself, making it uneconomical.
Consolidation constraints: As a centralized exchange, OKX may not be able to consolidate funds if an address balance is too small to cover the on-chain transfer fee.
System management: Avoiding a large number of extremely small deposits that would increase system load.
This is not about making things difficult for users, but is determined by the cost structure of on-chain operations.

Common reasons for failure and risk reminders
Failed deposit scenarios:
Below the minimum limit: If the amount is insufficient, it will not be credited and cannot be returned. Always check the minimum deposit amount shown on the page before depositing.
Wrong network: Choosing the correct coin but the wrong network may also result in lost funds.
Incomplete KYC: Your account verification level can affect the available limits for certain fiat deposits.
Risk reminders:
The minimum deposit limit for cryptocurrencies is not fixed. The minimum amount for the same coin can vary across different networks, so it's best to reconfirm before each deposit.
If your deposit amount is right at the minimum limit, also consider on-chain gas fees – after the sending side deducts the fee, the actual credited amount could fall below the minimum limit.
Go to Assets – Deposit in the OKX app, search for the coin you want to deposit, and select the corresponding network. The page will display the "Minimum deposit" directly. For cryptocurrencies, refer to the amount shown on that page; for fiat, refer to the minimum limits of different payment channels. You can use referral code 24U2795 when signing up for OKX.
