​​CoolWallet Integrates Rabby For Advanced Multi-Chain Security

The CoolWallet team has partnered with the Rabby team, enabling you to explore up to 6 chains and enjoy multiple DeFi choices with enhanced ease of use. The integration provides access to a user-friendly, secure multi-chain wallet experience.

What is Rabby?

Rabby is a browser extension wallet designed for multi-chain scenarios. It can automatically switch to the corresponding blockchain based on the DeFi website you are visiting. With the rise of Web3 and DeFi, MetaMask has become the primary way to connect to Dapps. However, MetaMask works mainly for a single-chain scenario, which can be inconvenient for users looking to navigate a multi-chain world.

With the launch of Rabby, users can now enjoy DeFi Dapps evolving in a multi-chain ecosystem. If you are familiar with Metamask, it will be very easy for you to interact with Rabby as they work similarly. 

In addition, aiming to enable users to understand what they are really signing, Rabby wallet will automatically parse the transaction content for users in Rabby’s signing confirmation pop-up window, effectively combating blind signing.

Why should I use Rabby with the CoolWallet App?

Advanced security technology to ensure the safety of your DeFi journey

With a unique, sleek credit card design, CoolWallet is equipped with advanced security technologies, such as an EAL 6+ secure element, encrypted Bluetooth connection (AES 256 military-grade), and 2+1 factor authentication (biometric and physical verification of all transactions via the app and card). 

As your private key is permanently locked inside CoolWallet’s EAL6+ secure element, your digital assets remain protected against external hacks and scams.

Supported by its security rule engine, Rabby sends each transaction into the engine for screening before users sign it to help users to identify the potential risks. Rabby also alerts users if it finds any potential vulnerabilities, helping users to proactively safeguard their assets.

By integrating Rabby wallet, CooWallet offers you a seamless multi-chain solution with advanced security, protecting your digital assets from malicious actors.
