It relies on a Replayed on Chain trading mechanism, which uses the on-chain and off-chain synchronized ledgers to allow instant trading while protecting the assets of the trader.

What Makes DEx.top Unique?

DEx.top is a logical continuation of the trend toward decentralized exchanges for blockchain transactions involving tokens and cryptocurrency. DEx.top stands out from most competitors with its ability for users to get instant trading, like they would typically only find on centralized exchanges. This is possible because of DEx.top’s double ledger system that includes one ledger on the chain and one off it. Matching and trading take place off-chain, which allows for the same speed as a centralized exchange. After this, all orders get “Replayed on Chain” to sync the on-chain ledger with the off-chain ledger, updating it with user information, like transactions and balances.

This method is like that of the only other decentralized exchange that uses a two-ledger system, IDEX, but DEx.top stands out from that platform, as well. While IDEX requires users to pay gas fees for withdrawals, DEx.top absorbs these. DEx.top also has more avenues for customer support (including Twitter, email, Facebook, Telegram and Zendesk) and offers 24/7 availability, plus has lower minimums for trades and withdrawals.

DEx.top Account Signup

To make an account and begin trading on DEx.top, you will need to use the MetaMask plugin with your Brave, Firefox or Google Chrome browser. Once you are logged into MetaMask and connected to the Ethereum Mainnet, you can register by clicking “Sign Up” on the top right corner of the DEx.top homepage. Enter an email address and password, and then go to your email to find a confirmation email. Click on the link, and your registration will be complete.

Account Signup

Both deposits and withdrawals are done via MetaMask and found on “ETH Actions” on your “Balances” page. The process is straightforward, as you simply fill in a form and follow the on-screen directions.

How Do You Trade with DEx.top

Once you log into your DEx.top account and have deposited cryptocurrency, you can go to the “Exchange” tab from the main navigation bar at the top of the website. This page has all the expected tools from a cryptocurrency exchange, including a list of markets on the left side of the page and a graph on the right side.

Trading Screen

Scrolling down slightly will take you to the area to place an order on the left and the order book on the right, which lists price, amount, and total. You can specify the aggregation level in the order book, which determines the number of significant figures token prices are rounded up to. This allows traders to view the price range and depth of the orderbook, a feature not offered by any other two-ledger decentralized exchange currently.

Directly below the order book, you can view recent trades. Below the section to make an order, you can view your open orders and order history.

Buy Sell

To trade on DEx.top, you must have the MetaMask extension installed and logged in, which is why it is required to make an account. You must then also generate a Trading Address which will be an Ethereum wallet address. You will then need to fund that by sending some ETH or other currency you wish to trade on the platform.

Assuming the plugin is activated and you are logged into your account, you will see side-by-side order forms to buy or sell your chosen cryptocurrency against ETH. Either form lets you fill out the price in ETH, the amount in your chosen token, and when the order will expire, with the default set to seven days.

The ability to set order expiration dates is important in decentralized exchanges for two reasons: first, it nullifies an attack vector if attackers gain access to the platform, they will not be able to trade against old unfilled orders (which could be priced very differently from the current market) and hence cause losses to traders. This feature gives DEx.top a security advantage over other decentralized exchanges in the market today.

Secondly, traders don’t have to worry about making losses on open orders that they’ve already signed with their private key due to market fluctuations over time.

On the order form, the field of total (in ETH) gets automatically filled in. Below the fields, you will see a button to “Buy” or “Sell.” Above the fields, the buy form lists the lowest sell at the time and the max amount, while the sell form lists the highest buy and the max amount.


DEx.top Trading Charts

The charts on the Trade page are from TradingView, so most users will be familiar with them. The information regarding your chosen pair is shown in a candlestick chart with a volume chart directly below it. As you hover over a point in the chart, you can see the specific time and date (horizontal axis) and open, high, low, and close, which appear at the top of the chart. There are also various options, such as changing the full span of the chart to six hours, one day, three days, or 30 days and the intervals to five, 15, or 30 minutes or one hour, day, or week. You can also adjust the type of chart to bars, hollow candles, Heikin Ashi, line, area, or baseline.


Directly above the chart, you will see the cryptocurrency pair you are looking at, as well the current price of the given token in ETH and the percent change.

DEx.top Fees

Operations on the Ethereum blockchain cost gas to execute. Like other decentralized exchanges, trades, withdrawals and deposits are all settled on-chain on DEx.top and will incur gas costs. The platform’s fees are broken down below:

Trading Fees: Like other platforms, DEx.top relies on a maker-taker model to determine trading fees. This fee is designed to be small, so it can cover the Ethereum gas cost. Maker fees are for those who add liquidity to the platform’s market by making a limit order to sell or buy. Taker fees are for those who remove liquidity by placing an order that executes against an existing order. As part of the maker-taker model, taker fees are slightly higher, as this encourages users to maintain the order book. At the time of writing, taker fees are 0.2 percent and maker fees are 0.1 percent, but DEx.top notes they are subject to change.

Withdrawal & Deposit Fees: deposits usually cost about 0.001 to 0.002 ETH to cover the Ethereum network’s gas fees. Gas fees for withdrawals are currently absorbed by DEx.top to encourage early use.


DEx.top is a newly launched decentralized exchange that allows for instant trading without the drawbacks of using a centralized exchange. The platform uses both an on-chain and an off-chain ledger to make this possible and has been optimized to maximize gas efficiency, saving you money on your trades.

The interface of the DEX is well designed and feels very much like using any other centralized exchange, the trading screen is clean and easy to see all the information you will need when making your trades and beginner’s should be able to quickly get started trading Ethereum-based tokens.

Apart from 24/7 availability on both its English and Mandarin customer support channels, there is also a support email listed on the contact page. Still, do make sure you are familiar with how the site works before conducting any large trades though – things like double-checking wallet addresses and carrying out small test-transactions first will help you get used to the system with a smaller risk.

I would like to see some more transparency about who is behind the site, company details and so on but that is not as important for a Decentralized exchange as you are just interacting with smart contracts as opposed to trusting a third-party to be custodian of your cryptocurrency.

The amount of tokens at this point is not huge, but the exchange is new so I would expect that to increase as time goes on.
