How to Trade via OnChain

Buying and selling are the core operations of OnChain transactions:

• Buying involves using USDT or ETH/BNB/SOL from the Spot Account to purchase the target cryptocurrency.
• Selling involves converting the OnChain Assets held in the Spot Account into USDT.

Before using CoinEx OnChain, please bind the 2FA tool first.

Example:  Buying Token A on the Ethereum (ETH) network via OnChain:

1. Buying Token A:

(1) Select the token you wish to buy by either searching for the smart contract address or choosing from the “Hot” list.

(2) Enter the payment cryptocurrency (USDT or ETH) and amount, set slippage tolerance, and confirm the estimated receiving amount.

(3) Submit the buy order and wait for the transaction to complete.

(4) The purchased Token A will be deposited into your Spot Account > OnChain Assets. They can be sold but cannot be withdrawn.

2. Selling Token A:

(1) Select the token you wish to sell.

(2) Enter the selling amount, set slippage tolerance, choose the receiving cryptocurrency (USDT or ETH), and confirm the estimated receiving amount.

(3) Submit the sell order and wait for the transaction to complete.

(4) After selling Token A, the funds will be directly deposited into your Spot Account. You can withdraw the funds or use them for another transaction at any time.

3. View OnChain assets

Go to [Assets] > [Spot] > [OnChain] to view the OnChain assets. Click History, and filter "OnChain" to view changes in your OnChain assets.

4. Notes:

(1) Transfers between Spot Assets and OnChain Assets within the Spot Account are not supported.

(2) When trading via OnChain, the payment/receiving cryptocurrency can be either USDT or the native token of the blockchain where the asset is created. For example, when trading via OnChain for the Ethereum-based assets, you can choose USDT or ETH (the native token of Ethereum).

How to Search Tokens

On the OnChain page, the Hot List is shown on the left. Switch between [ALL], [SOL], [ETH], or [BSC], and use the star icon to favorite tokens.

You can search by token name (Hot List only) or by contract address (all tokens).

Note: Trading is unavailable if:

• The token has low TVL or liquidity.

• The token is already listed on the Spot market.

• Other reasons.

   

Market Order Trading

1. How to Buy

(1) After finding the token, select [Market] in the trading section and enter the payment amount.

Note:

• The default payment token is USDT, but you can switch to the chain’s native token (SOL, ETH, BNB).
• Use shortcuts [25%], [50%], [75%], [MAX] to quickly enter payment amounts.
• If your balance is insufficient, click the [+] button to add funds via Deposit or Transfer.

(2) Set Slippage

• Default slippage is 5%. You can customize it up to 50%.
• Slippage affects the final amount you receive.

(3) Review “Receive (estimate)” and “Minimum received”, then click [Buy]. Confirm the order details and submit the order.

Note: The specific transaction time is determined by the characteristics of different networks, and transactions can generally be completed within 5-30 seconds.

(4) After creating the order, you can view it under [Pending Order].

2. How to Sell

To sell OnChain assets, select [Sell] in the trading section, choose [Market], enter the amount, and set the slippage if needed.

Stop-Market Order Trading

1. Features

• Requires a Stop price. When the market reaches this price, a market order is placed automatically. The stop price defaults to USDT but can be switched to native tokens (BNB, SOL, ETH).

  Note: Only USDT and native tokens are supported as the Stop price.

• Stop-Market orders have Time in Force (validity period). If not triggered within this period, they are canceled. The default is 30 days and cannot be modified for now.

2. How to Buy

(1) Select the trading token and click [Stop-Market]. 

Set Stop price or Market cap, choose a payment cryptocurrency (USDT, ETH, BNB, SOL), and enter the amount. Then set slippage (default 5%, max 50%) and click [Buy].

(2) Click [Buy], review the order details, and click [Confirm].

(3) After creating the order, you can view it under [Pending Order] > [Stop-Market]. You can click [Cancel] to revoke the order here.

3. How to Sell

Switch to [Sell], set the Stop price or Market cap, slippage, enter the sell amount, and click [Sell].
