The current user experience in decentralized finance (DeFi) can be complicated and intimidating, especially for those who are new to crypto.

However, we’re excited to introduce a product that provides an intuitive entrypoint into DeFi—the Blockchain.com Decentralized Exchange Aggregator (Blockchain.com DEX Aggregator). We’ve made the process really simple.

With the Blockchain.com DEX Aggregator, you can access a range of decentralized exchanges to swap thousands of tokens on the Ethereum and Polygon blockchains right from your Blockchain.com DeFi Wallet, without ever giving up control of your crypto.

What is a decentralized exchange?

A decentralized exchange is a peer-to-peer marketplace where crypto can be traded directly between buyers and sellers.

Unlike centralized exchanges where the transfer of assets is managed by an intermediary or custodian, decentralized exchanges allow you to trade directly from your DeFi Wallet by interacting with self-executing agreements written in code called smart contracts.

These smart contracts automatically establish the price of cryptocurrencies, facilitate trades, and settle transactions directly on the blockchain.

What are the benefits of a decentralized exchange (DEX)?

Reduced counterparty risk: As there are no intermediaries or custodians involved in decentralized exchanges, there’s less risk that one of the parties involved is unable to fulfill their obligations.
More tokens: Decentralized exchanges allow you to access essentially any token that’s minted on the blockchain they’re built on. There are also new tokens being listed all the time, increasing the opportunity to get in early on projects.
Greater access: Anyone with an internet connection can trade on a decentralized exchange. This has made them particularly popular in countries where many don’t have access to traditional financial services.
Market efficiency: Self-executing smart contracts and access to a diverse range of liquidity pools provides a highly efficient trading experience with competitive pricing and rapid execution. In combination with our De-Fi Wallet, you can maintain complete control over your crypto assets from beginning to end.

What is a DEX Aggregator?

A DEX Aggregator is a platform or protocol that combines liquidity from multiple decentralized exchanges (DEXs) into a single user interface.

This provides users with access to a larger trading volume and better prices. It automatically splits and routes users' orders across multiple DEXs finding the most competitive pricing and execution model. Using a DEX aggregators can offer reduced slippage and lower trading fees compared to trading on a single DEX.
