Binance is a cryptocurrency exchange that was founded in 2017 by Changpeng Zhao. It is currently one of the largest cryptocurrency exchanges in the world by trading volume. Binance offers a wide range of cryptocurrency trading pairs, as well as fiat-to-crypto trading pairs in some regions.

In addition to its trading platform, Binance offers other services such as staking, lending, and margin trading. Binance also has its own cryptocurrency, called Binance Coin (BNB), which can be used to pay for trading fees on the platform and offers discounts on those fees.

Binance has faced some regulatory challenges in various countries, but it continues to operate in many regions and has expanded its services to include decentralized finance (DeFi) offerings and a blockchain platform called Binance Smart Chain.
