Crypto Companies Directory

Zashi is a non-custodial wallet application for mobile and web platforms that operates exclusively with Zcash. Developed by Electric Coin Co., the organization responsible for the Zcash protocol, the wallet is designed to route all transactions through shielded pools by default. These shielded transactions employ zero-knowledge proofs to encrypt sender identity, receiver identity, and transaction amounts, rendering this information cryptographically private and untraceable on the blockchain. The wallet incorporates integrated Tor network functionality to provide network-level privacy protections alongside the on-chain privacy mechanisms. It supports unified addresses, which enable automatic routing of transactions to the most private available transaction type. Users retain full control of their private keys, with no custodial access granted to the development team or any third party.
