Overview
BlockSec
BlockSec provides you with a comprehensive security stack to protect your blockchain protocols and smart contracts throughout their entire lifecycle. You can use their automated tools to identify vulnerabilities during development and receive rigorous manual audits from their security experts before you launch. This proactive approach helps you catch critical bugs that could lead to devastating financial losses in the decentralized finance space.
Once your project is live, you can monitor your smart contracts in real-time using their Phalcon platform. It allows you to detect suspicious transactions as they happen and even block attacks before they are finalized on the blockchain. By integrating these security layers, you can build trust with your users and ensure your digital assets remain safe from the evolving landscape of crypto-specific threats.
Zengo
Zengo is a self-custodial crypto wallet that removes the biggest risk in digital assets: the seed phrase. Instead of relying on a vulnerable piece of paper, you use Multi-Party Computation (MPC) cryptography to secure your funds. This means there is no single point of failure, protecting you from hacks and accidental loss while ensuring you always maintain full control over your private keys.
You can buy, sell, and swap over 120 crypto assets directly within the app using your preferred payment methods. The platform also features a built-in Web3 firewall that alerts you to suspicious smart contracts before you sign them. Whether you are a beginner or an experienced investor, you get a secure way to manage your portfolio with 24/7 live customer support available whenever you need assistance.
