Before you deposit: what OKX checks first

OKX's network-selection help page states that you have to complete identity verification before you can make a deposit, so do that first; our OKX KYC level guide explains what Level 1 and Level 2 ask for and what each unlocks. The P2P marketplace and the third-party gateways ask for the same thing: a registered account, a verified email or phone number and completed verification. The card gateways add one more rule: the name on the payment account has to be identical to the name on your OKX account.

If you are still choosing an exchange, the OKX profile lists availability, products and current fees in one place. Everything below was read from OKX's own help centre and public data on 13 October 2026.

Method 1: deposit crypto from another wallet or exchange

This is the cheapest route when you already hold crypto somewhere else, because OKX does not set the network fee; the platform you send from does.

1. In the OKX app, open Assets and tap Deposit (on the web: Assets in the top menu, then Deposit). 2. Search for the coin, for example USDT. 3. Choose the network. This is the step that matters most: the network on OKX must be the same network you select when you withdraw on the sending platform. ERC20 on one side and TRC20 on the other means a failed deposit. 4. Read the minimum deposit amount shown on the same page. 5. Copy the deposit address (and the tag or memo if the coin shows one). 6. On the sending wallet or exchange, paste the address into the withdrawal form, choose the same network, enter the tag if required and confirm.

OKX updated some deposit addresses on 27 March 2025. Old addresses still work, but OKX asks anyone who saved or allowlisted an OKX address to copy the current one from the deposit page.

Which USDT networks OKX lists

OKX's public fee list for USDT shows 16 networks on 13 October 2026: Aptos, Arbitrum One (USDT0), Avalanche C-Chain, Berachain (USDT0), Ethereum (ERC20), Monad (USDT0), Optimism, Optimism (USDT0), Plasma (USDT0), Polygon (USDT0), Solana, Tempo, TON, Tron (TRC20), Unichain (USDT0) and X Layer (USDT0). BNB Smart Chain is not on the list, and OKX's help page says plainly that it does not support depositing USDT on BSC, even though BNB itself can still be deposited on that chain. If your other exchange only offers BEP20 for USDT, pick a different network or a different coin.

How long it takes

Arrival time depends on block confirmations. OKX gives two examples: USDT on Tron needs 19 confirmations and USDT on Ethereum needs 32. On Layer-2 networks such as Optimism, Base or Arbitrum One, OKX credits the deposit based on the Layer-1 status of the bundle plus the Layer-2 confirmations, and congestion on any chain stretches the wait.

Method 2: buy with local money on OKX P2P

P2P is how most readers outside Europe and the US fund an OKX account with local currency. You are not buying from OKX: you buy from another verified user who posted an ad, you pay them through your bank or wallet app, and OKX holds the seller's crypto in escrow until the seller confirms your payment.

• OKX fee: none. OKX's P2P FAQ says there is no service fee and trading starts from 1 USDT.
• Your real cost: the ad price itself, plus any fee your bank or payment app charges for the transfer.
• Payment methods: whatever the seller accepts, such as bank transfer, SPEI, Mercado Pago, Nequi, Yape or PIX.

The steps: Trade > Buy and sell > P2P, choose your currency and USDT, filter by payment method, open an ad, enter the amount, pay the seller from your own account, then tap Payment completed. Keep every message inside the OKX chat, because OKX uses it as evidence if you need to open a dispute.

What P2P prices looked like on 13 October 2026

We read OKX's public P2P order book at 14:49 SGT (06:49 UTC). "Best price to buy" is the cheapest ad selling USDT; "best price to sell" is the highest ad buying USDT. The gap is our arithmetic and is the closest thing P2P has to a fee.

The Brazilian row is the warning: only nine ads were selling USDT for reais at that minute, so the gap was seven times wider than in Mexico. A thin market costs more than any trading fee, and prices move every minute, so always compare a few ads before you order.

P2P rules that catch new users

OKX limits how often you can cancel. A new user (fewer than three completed P2P orders) is restricted after more than five cancellations before payment in one day, or more than three after tapping Payment completed. Restrictions start at 15 minutes and escalate to a full day. Separately, a P2P purchase can be held by OKX's "T+N" risk control: the crypto you bought may be blocked from withdrawal or P2P resale for N days, after which the system lifts the hold automatically.

Method 3: card or bank through a third-party gateway

Under Trade > Buy and sell, OKX also shows partner gateways that take cards and bank payments. Each provider runs its own onboarding and verification, sets its own buy and sell limits, and may not serve your region at all. Most settle on-chain in 1 to 30 minutes; selling back to a bank account takes 1 to 3 business days, or minutes to a digital wallet.

When a deposit does not show up

• Locked by the Travel Rule. In regulated regions OKX can ask who sent the funds. Open the Asset page, find the locked deposit, tap Submit, and say whether it came from an exchange, a card gateway or a private wallet, with the sender's legal name. Tick "I'm the sender" if it was you.
• Missing or wrong tag. Contact support with the coin, amount, the correct and incorrect tag and the transaction hash.
• Below the minimum. OKX says amounts under the minimum are neither credited nor refunded.
• Unsupported token or network. Check the token contract under Assets > Deposit before sending.
• Combined deposits. Send one deposit per transaction; batching several into one transfer can fail.

Quick answers

Does OKX charge a fee to deposit crypto? The network fee is charged by the platform you send from. OKX's P2P marketplace has no service fee; payment providers may charge their own.

Can I deposit USDT on BEP20 to OKX? No. OKX does not support USDT deposits on BNB Smart Chain.

What is the minimum deposit on OKX? It depends on the coin and network and is shown on the deposit page; amounts below it are lost.

Why is my OKX deposit locked? Usually a Travel Rule check or a P2P T+N hold; the first needs sender details, the second clears on its own.

Can I deposit without KYC? No. OKX requires identity verification before deposits.
