Big news!

WalletConnect, an open protocol for connecting desktop DApps to mobile wallets, is now enabled in our AT.Wallet. WalletConnect allows you to interact with any DApp (decentralized application) on Ethereum and keep your private keys secure at the same time. Learn more about WalletConnect and DeFi Apps with us, and we will show you how to swap and invest tokens using AT.Wallet below.

What is DeFi?

DeFi, which stands for “decentralized finance,” refers to the ecosystem comprised of financial applications that are being developed on top of blockchain systems. It provides the same financial services as traditional banking with smart contracts on the Ethereum network. DeFi platforms allow people to swap, invest, lend and borrow tokens through various DeFi applications.

Currently, the three largest functions of DeFi are: (Learn more about DeFi on Binance Acadamy )

Creating monetary banking services (e.g., issuance of stablecoins)
Providing peer-to-peer or pooled lending and borrowing platforms
Enabling advanced financial instruments such as DEX, tokenization platforms, derivatives and predictions markets

The two apps with the most heavily audited contracts are Uniswap and KyberSwap, supporting WalletConnect. Users can now use these DApps as an alternative exchange method for crypto assets.

What is WalletConnect?

WalletConnect is an open-source protocol for connecting decentralized applications to mobile wallets with QR code scanning or deep linking. A user can interact securely with any Dapp on Ethereum from their mobile phone, making WalletConnect wallets a safer choice than desktop or browser extension wallets. Also, it can be customized to support other blockchain transactions. WalletConnect is integrated with Binance DEX. By scanning the WalletConnect QR code shown on binance.org, you can easily link up your mobile wallet.

Uniswap

Uniswap is a protocol on Ethereum for swapping ERC20 tokens. Unlike most exchanges designed to take fees, Uniswap is designed to function as a public good—a tool for the community to trade tokens without platform fees or mediators. Also, unlike most exchanges, which match buyers and sellers to determine prices and execute trades, Uniswap uses a simple math equation and pools of tokens and ETH to do the same job. Uniswap is an Ethereum based exchange that allows anyone to swap ERC20 tokens. Uniswap V2 launched in May 2020, enabling direct ERC20 to ERC20 swaps and adding a host of technical improvements. With Uniswap, you can swap tokens between different addresses and invest directly into the pool.
