What Are OKX Deposit Limits? Single Transaction and Daily Limits Explained
OKX does not have a single deposit limit number; it depends on the deposit method you choose and your account's identity verification level. On-chain deposits have no fixed limit, while fiat deposits and C2C trading have their own single transaction, daily, or cumulative limits.

Prerequisite: Confirm Your KYC Level
OKX's limit system is directly tied to your identity verification level; the higher the level, the greater the available limits. For details on the differences between KYC levels and how to upgrade, please refer to our related guides. The minimum level includes:
Unverified Account: Cannot deposit or trade.
Verified Account: On-chain deposits have no limit. C2C buy orders: single transaction limit 10–20,000 CNY, cumulative purchase limit 20,000 CNY; C2C sell orders: single transaction limit 10–40,000,000 CNY. 24-hour withdrawal limit 10,000,000 USD.
Step 1: On-chain Deposit (Cryptocurrency Transfer) — Highest Limits
What it is: Deposit cryptocurrency from an external wallet to OKX.
How to do it:
The on-chain deposit limit is primarily determined by your KYC level.
According to the OKX Help Center, after completing basic identity verification, there is no upper limit for on-chain deposits. As long as your source wallet has sufficient balance and the single transaction amount meets the minimum deposit requirement for that cryptocurrency, you can deposit.
What constitutes completion: Confirm that your OKX account has completed identity verification and that the deposit amount is greater than the "minimum deposit amount" shown on the deposit page.
⚠️ Important Reminder: On-chain deposits have a "minimum deposit amount" requirement. If the deposit amount is below this threshold, the assets will not be credited and cannot be refunded. You can check this value on the OKX App or website by going to the [Deposit] page, selecting the coin and network.
Step 2: Fiat Deposit – Limits Depend on the Specific Channel
What it is: Deposit fiat currency via bank transfer, credit card, etc.
How to do it:
Fiat deposits have specific single transaction, daily, and monthly limits. The exact numbers depend on your deposit method and KYC level.
You can view the remaining limit for each method directly on the Deposit page, and click the ⓘ icon next to it for detailed information.
Common Fiat Limit Reference (using USD as an example):
| Fiat | Payment Method | Min per transaction | Max Daily Cumulative (Individual) | Max 30-Day Cumulative (Individual) |
|---|---|---|---|---|
| USD | Domestic Wire Transfer | $50 | $500000 | $1000000 |
| USD | ACH Bank Transfer | $1 | See user page display | See user page display |
What constitutes completion: You have confirmed the remaining limit of the selected method on the Deposit page and ensured that the deposit amount is within the available limit.
⚠️ Limit Reset Rules: Daily, weekly, and monthly limits are usually calculated on a rolling basis. For example, the daily limit is valid for 24 hours from the time a transaction is completed, and does not reset at midnight. If the monthly limit is reached, it resets 30 days after the transaction is completed.
Common Reasons for Failure
Fiat deposit amount is below the single transaction minimum: For example, the minimum for USD wire transfer is $50; sending $49 will be returned or failed.
You are close to or have reached the periodic limit: If you have accumulated a large number of deposits this week or month, the remaining limit may not be enough to complete this transaction.
Insufficient account verification level: If you have not completed KYC or have only partial verification, some features or high-limit deposit channels will not be available to you.
Risk Reminder
Fiat deposit limits are tied to your KYC level. If you often encounter "exceeded limit" prompts, consider upgrading your verification level to obtain higher limits. For example, after upgrading to a higher level, the daily withdrawal limit may increase from $10,000 to $1,000,000.
The limits for different deposit methods are calculated independently, but they may also stack. For example, the limits for USD wire transfer and ACH transfer are calculated separately, each subject to its own channel restrictions.
