Depositing SNX on OKX falls into two scenarios: if you don't have SNX yet, the easiest way is to buy it directly on the exchange with USDT; if you have SNX in a wallet and want to transfer it in, the key is to choose the correct network — SNX is an ERC-20 token on Ethereum. Selecting the wrong network will result in lost funds.

1. Determine where your SNX is and on which network

What to do: Figure out the current state of your SNX: whether you haven't bought it yet, it's already on OKX, or it's in a blockchain wallet.

How to do it:

Situation A: You don't have SNX yet. No deposit is needed; just buy SNX directly on OKX. Open OKX, search for the "SNX/USDT" trading pair, and buy with USDT. OKX spot trading fees are maker 0.08%, taker 0.10% (source: OKX official website, 2026-07-08).

Situation B: Your SNX is already in your OKX account. No action is needed. If you want to move it to an external wallet, follow the withdrawal process.

Situation C: Your SNX is in a blockchain wallet (e.g., MetaMask). SNX is an ERC-20 token, primarily on the Ethereum mainnet. Open your wallet and check the network — if it's Ethereum Mainnet, choose the ERC20 network when depositing. Among the networks OKX supports for SNX, ERC20 is the main deposit option (source: OKX Help Center, 2026-07-08).

When is this step completed: You have clearly answered "Where is my SNX?" and know which path to take.

Prerequisites: Your OKX account must be verified (KYC). Unverified accounts cannot deposit.

2. Depositing SNX from a blockchain wallet to OKX

What to do: Transfer SNX from your wallet into your OKX exchange account.

How to do it:

  1. Open the OKX App, tap Assets at the bottom, and select Deposit.

  2. Search for "SNX".

  3. Select the network: Choose the ERC20 network (Ethereum mainnet) for SNX. If you are unsure which network your SNX is on, ERC20 should be your default choice — Synthetix official documentation states that withdrawing SNX to the Ethereum mainnet (ERC-20) is the standard method.

  4. The page will display a deposit address and a minimum deposit amount. If you deposit less than the minimum, the funds will not be credited and cannot be returned (source: OKX Help Center, 2026-07-08).

  5. Copy the address, open your wallet, and initiate the transfer. Make sure your wallet is on the Ethereum Mainnet.

When is this step completed: The transfer has been submitted and the OKX Assets page shows "Depositing" status.

Prerequisites: In addition to SNX, your wallet must have ETH to cover the gas fee.

Common reason for failure: SNX is on the Ethereum mainnet; choosing the wrong network (e.g., Polygon or BSC) will cause loss of funds. OKX explicitly warns that selecting the wrong network may result in permanent loss of funds.

Risk warning: Blockchain transactions are irreversible. A wrong address or network selection cannot be undone. For your first deposit, always test with a small amount first, and only transfer the remainder after confirming the test arrives safely.

3. Buying SNX directly on OKX (if you don't have any)

What to do: If you don't hold SNX yet, buy it directly on OKX with USDT. This is simpler than depositing from a wallet.

How to do it:

  1. Ensure your account has USDT. If not, deposit funds first via bank transfer, credit card, or C2C. Bank transfers typically take 1-3 business days.

  2. Go to Trade - Spot, and search for "SNX/USDT".

  3. Choose a market order for an immediate fill or a limit order to set your desired price.

  4. Once filled, the SNX will appear in your spot account.

When is this step completed: Your spot account shows an SNX balance.

Prerequisites: Your account must be KYC-verified and have a sufficient USDT balance.

Common reason for failure: Confusing "SNX" with "sUSD". SNX is the governance token of Synthetix, while sUSD is a stablecoin within its ecosystem. They are completely different assets.

4. Withdrawing SNX from OKX to an external wallet

What to do: If you bought SNX on OKX and want to store it in your own wallet, follow these steps.

How to do it:

  1. Go to Assets - Withdraw and search for SNX.

  2. Enter your external wallet address.

  3. Choose the correct network: Select the chain your wallet address is on (usually ERC20).

  4. Confirm the amount and fee, then complete the verification.

When is this step completed: The withdrawal status shows "Completed" and the SNX arrives in your external wallet.

Prerequisites: The external wallet must support SNX (e.g., MetaMask). Always do a small test withdrawal first.

Common reason for failure: The external wallet may not support the network you selected. Before withdrawing, make sure your wallet is configured for the corresponding network.

What to do next:

  • If you already have SNX on-chain: Follow Step 2. First, transfer a tiny test amount (e.g., 0.1 SNX) to confirm it arrives, then send the rest. ERC20 deposits usually take 10-30 minutes, longer during network congestion.

  • If you don't have SNX yet: Follow Step 3. Search SNX/USDT on OKX and buy with USDT, saving yourself the gas fees of an external deposit.
