Top 9 Best Decentralized Cryptocurrency Exchanges [2021 Edition]



Are you looking for much safer and secure cryptocurrency exchanges because you are afraid of your cryptocurrencies being stolen on centralized exchanges?

If your answer is YES (!), then I think we have the same concerns. And that is why this article came to be: we want to see what are the best decentralized exchanges in the market right now. Actually, not only that but we want to see which one is actually THE best decentralized exchange out there.

So let’s get going.

First, a bit about the necessity of decentralized trading places and the negative impacet centralized, non-transparent exchanges have on the whole industry.

Centralized exchanges are easy to use, easy to access and they provide advanced trading functionalities, but they are not the best in terms of safety when used. Moreover, hacks are not an uncommon event in the cryptocurrency scene and incidences such as Mt. Gox hack and Bitfinex hack are not news anymore as most of us know about it.

Although centralized exchanges fundamentally violate the basic tenants of a decentralized crypto economy, we are actually forced to use them because we don’t have another option as the decentralized cryptocurrency infrastructure and decentralized exchanges are still being built.

But when it is ready in a full-fledged manner it will be breath a new life itself into the crypto-sphere because decentralized exchanges do not require a third party to store your funds, instead, you are always directly in control of your coins and you conduct transactions directly with whoever wants to  purchase or sell your coins.

That’s the reason why we start looking around and find out which are the best decentralized exchanges currently available in the market.

Top 6 Best Decentralized Cryptocurrency Exchange


AirSwap is a New York and Hong Kong-based decentralized cryptocurrency exchange designed from the ground-up with privacy and security in mind. This new token exchange project is built on Ethereum and aims to provide customers with global, peer-to-peer trading with no intermediaries and zero trading fees (!).

Utilizing the so-called “Swap protocol,” AirSwap focuses on doing ERC20 trades.

AirSwap unveiled a new data aggregator product back in summer 2019, a move that shows the firm is looking to stand out in the market decentralized exchanges. 

The new product, dubbed DexIndex, provides an overview of how different ERC20 tokens are trading across a number of decentralized exchanges, including AirSwap’s market. The tool could be useful for a number of participants across the Ethereum ecosystem.


The exchange is hosted on the Ethereum blockchain architecture in the form of two smart contracts, a “Factory” contract and “Exchange” contract. The “Factory” smart contract contains an exchange registry, and a method to deploy an “Exchange” contract for a particular ERC20 token.

Thanks to this, any valid ERC20 token can be exchanged on Uniswap via their own unique exchange contract. There is exactly one exchange contract per ERC20 token and if a token does not yet have an exchange, one can be created by anyone using the Uniswap factory contract.

Market making isn’t done by specifying the prices you want to sell/buy for. What happens is that Uniswap makes markets with the help of a deterministic algorithm called Automated Market Maker (AMM).

The algorithm quotes prices to end users according to a pre-defined rule set called “Constant Product Market Maker Model”. This AMM is able to always provide liquidity, no matter how large the order size nor how tiny the liquidity pool; the trick is that the price of the coin asymptotically increases as the desired quantity increases. While larger orders tend to suffer as a result, the system never has to worry about running out of liquidity.

Uniswap, while not aiming to replace traditional exchanges, brings forth a couple of additional extras that the market might be interested in. In theory, it makes market manipulation more difficult and allows for a more stable price situation overall. 

Binance DEX

Binance DEX will be built on top of the Binance Chain, upcoming blockchain that will allow Binance’s native token BNB to move away from Ethereum onto its own native mainnet.

The chain is being built on top of Cosmos’ Tendermint protocol; more precisely, Binance forked the protocol and removed some of its elements (smart contracts for example) to create a scalable product that will be able to achieve high transaction throughputs required by Binance standards.

Binance’s new native chain will rely on modified Tendermint PoS algorithm which will basically operate as a Delegated Proof of Stake algorithm. The chain (once its testnet goes live in a couple of weeks) will be tested on 11 validating nodes. Total number of validators won’t go up much higher when the mainnet ultimately goes live.

Not much is known about Binance DEX account creation model, but you likely won’t be required to go through the tedium of KYC/AML registrations to trade the stablecoin-like assets on the platform.

This might change if you, for example, decide to turn your Binance Chain-launched BTC stablecoin into real BTC. If that turns out to be a requirement and if your private key isn’t the only „ID“ you’ll ever need to exchange value on Binance DEX, then all the talk about decentralization goes up in the air.

If you would have bet on the right coins this year you could easily have 10xed your capital…

You could even have made as much as 100x which means you could have turned $100 into as much as 10k.
Experts believe this will happen again in 2021, the only question is which coin do you bet on?

Essentially, you are issued an IOU, a placeholder token on Binance chain that acts as a proxy for the actual BTC, ETH or other You get your real „physical“ coins when you withdraw them to your own wallet.

And while this means that Binance DEX won’t actually offer non-custodial storage, it does suggest that you’ll have a certain safety net in terms of your private keys. If you lose your private key you won’t lose access to your actual funds, but only to the Binance Chain-issued stablecoins.

This means that you could potentially regain access to your funds even without the private key. This does place alot of control over your funds into the hands of a third party, which is the complete opposite of what a proper DEX should do.


Bancor is supposed to be used in international trade as a unit of account within a multilateral clearing system. It is a so called “market maker” dapp which allows its users to purchase or sell smart tokens at prices that match those found on major exchanges.

While this service is similar to traditional exchanging, Bancor doesn’t match sellers and buyers; Instead, it allows users to purchase or sell BNT tokens which creates a built in smart contract based liquidity mechanism. With a Bancor Wallet which lets users purchase ETH with debit/credit card the platform is important for providing liquidity to crypto community. The platform offers over 90 active tokens (and plans on adding more) with over 4000 trading pairs.
