Metamask is one of the most well-known wallets for ETH and tokens in the ethereum network on the market, it works as an extension to your browser, very intuitive and effective, but I still have my doubts about its security, as it uses a subscription to allow third parties access your wallet to transact which causes me some suspicion, since I myself have been the target of theft through metamask when in a transaction made through Metamask they managed to divert several tokens from my portfolio and all my ETH. In the end, is it a safe wallet ?! However, you must be very careful with who transacts through it, because in these gaps that are the flaws.
