Shesster (ID: 00000027297a0893) Voted 5 ★ - Updated 10/23/2023 It's a wonderful tool to show you what type of transaction you are signing with your wallet in Crypto. It gave me confidence after a particular site was hacked. The connection is usually just signing that you own a wallet, but during the hack it showed the hacker giving access to funds. Once the hack was over it showed a simple signature with no allowance to access of funds again. That knowledge is invaluable in crypto to keep your wallet safe! MUST HAVE!
