How to Transfer Ethereum from MetaMask to OKX (Complete Tutorial)

Prerequisites for Ethereum Transfer

1. A fully synchronized MetaMask wallet with at least one Ethereum address containing ETH or ERC-20 tokens.

2. An active OKX account with completed identity verification and enabled deposit function.

3. Correct network selection—Ethereum Mainnet must be selected in both MetaMask and OKX deposit interface.

4. Sufficient ETH balance to cover gas fees for the outgoing transaction from MetaMask.

5. Accurate copy-paste of the OKX Ethereum deposit address without any trailing spaces or character corruption.

Step-by-Step Withdrawal from MetaMask

1. Open MetaMask extension and unlock the wallet using your password.

2. Ensure the network is set to Ethereum Mainnet, not a testnet like Ropsten or Goerli.

3. Click “Send” and paste the Ethereum deposit address obtained from OKX into the recipient field.

4. Enter the exact amount of ETH or token to transfer, double-checking decimal precision.

5. Review gas fee estimation; manually adjust if necessary to avoid excessive delays or overpayment.

OKX Deposit Address Retrieval Process

1. Log in to your OKX account via web or mobile application.

2. Navigate to Assets → Deposit → Cryptocurrencies.

3. Search for “ETH” and select Ethereum Mainnet as the chain option.

4. Click “Copy Address” next to the displayed wallet address—this is a unique, non-reusable deposit address tied to your OKX user ID.

5. Confirm that the address starts with “0x” and consists of exactly 42 hexadecimal characters.

Transaction Monitoring and Confirmation

1. After submitting the transaction in MetaMask, record the transaction hash (TxHash) shown on the confirmation screen.

2. Paste the TxHash into Etherscan.io to verify inclusion in a block and monitor confirmations.

3. OKX typically credits deposits after 12 network confirmations on Ethereum Mainnet.

4. Do not initiate duplicate transfers before the first transaction appears in OKX’s deposit history.

5. If the deposit remains uncredited beyond 30 minutes, cross-check the chain used in OKX against the one selected in MetaMask.

Common Questions and Answers

Q: Can I send ETH from MetaMask to OKX using a testnet like Sepolia?A: No. OKX only accepts deposits on Ethereum Mainnet. Sending via testnets results in permanent loss of funds.

Q: Why does OKX show “Deposit address not found” when I paste it into MetaMask?A: This usually occurs due to invisible Unicode characters, extra spaces, or selecting the wrong chain in OKX’s deposit interface. Re-copy the address directly from OKX’s official deposit page.

Q: Is there a minimum ETH amount required for deposit to OKX?A: OKX enforces no minimum deposit threshold for ETH, but users must ensure sufficient ETH remains in MetaMask to pay for gas fees.

Q: What happens if I send an ERC-20 token to my OKX ETH deposit address?A: OKX supports many major ERC-20 tokens on Ethereum Mainnet. As long as the token is listed and enabled for deposit on OKX, it will be credited automatically. Verify token compatibility on OKX’s deposit page before sending.
