Block Wallet (earlier called Blank Wallet) seeks to make crypto transfers safe and private, like bank transfers, using privacy-inducing smart contracts. Smart contracts are just like regular contracts, but instead of being drafted on paper, these contracts run in the form of protocols on the blockchain. The platform aims to tackle the issues related to privacy in the DeFi space. 

All new developments in the cryptocurrency and blockchain space hinder privacy to a great extent. Although there are privacy-enhancing tokens like Monero and Zcash in the market that enable users to transact privately, the most popular crypto platform is Ethereum, which still lags in this regard. So Block Wallet was introduced to help Ethereum add a layer of privacy to its operations. 

Block Wallet is a private, noncustodial Ethereum browser wallet that seeks to enable users to trade Ether (the native token of Ethereum) and other ERC-20 tokens privately and safely. Block Wallet does so by using smart contracts that aim to allow users to hide the amounts and the origins of their crypto assets held in a decentralized and frictionless manner.

The smart contract develops a new wallet address with the amount of crypto requested by the user each time a user makes a withdrawal. Block Wallet seeks to provide a layer of confidentiality on a public network by allowing private transactions and balances. So, it isn't easy to maintain privacy effectively and cheaply on Ethereum without Block Wallet. 

To help Block Wallet achieve the desired objectives, the platform introduced the BLANK token. Block Wallet charges fees for anonymity services, and all BLANK token holders seek to receive significant discounts on fees. Users who contribute to the DEX liquidity pool receive a portion of fees in BLANK tokens. 

Lastly, BLANK holders are eligible to utilize premium features of the platform and seek to get first access to all the functionalities.
