Veil is your ultimate defender against private key theft.
Veil protects your assets by frontrunning unauthorized transactions and transferring all user assets to a secure, pre-specificied backup address. It can be setup within seconds, without revealing your private key at any point in the process.
This project was made as part of Hack Lodge S22.
The immutability of transactions and lack of recourse in the event of a personal wallet hack has led to poor UX for crypto users. As recent events have shown, private keys can be stolen via highly-targeted hacks or security flaws in wallet infrastructure. Veil is intended to be the first-iteration towards mechanisms that mitigate the effects of private key theft.
Visit our website to get set up. Using Veil will require you to install a client tool that will presign certain transactions under the event that your wallet's funds are under attack. The client runs entirely locally. Veil will monitor the mempool for unauthorized transactins and broadcast the pre-signed rescue transactions to transfer funds to your backup address.
Follow the format of .env.template to update your .env file with the appropriate variables.
Our CLI command will compile a Rust Binary to pre-sign approve and rescue transactions. Requires Rust 1.56.1 or higher. You can install rust here.
