Essential Browser Extensions for Web3 Users

Currently, there are many potential threats in blockchain and general cyberspace. Especially threats from scammers, always hiding under the guise of normal addresses and smart contracts to steal assets of normal users and investors. Sometimes even experienced and technically knowledgeable people can be fooled. So today I would like to introduce to everyone some essential tools in protecting and securing assets against threats from the crypto market. These tools are useful for both newbies and those who have experience in the field of blockchain and security.
