Metamask wallet is secured in itself. Regardless of the platform or dapp been connected to so security is not an issue. First of all, all interaction or transaction with DeFiXy will only be approved with a confirmation on metamask (external the the DeFiXy platform) and if you are well familiar with the wallet, you will know that DeFixy or any other platform you may interact with using metamask has no access to your private key or mnemonic phrase.
In addition, security is of outmost importance and we have taken such measures to guarantee that and also, it is the reason that we choose this approach.
