DeFi wallets are usually your entry point into the DeFi ecosystem, so be sure the wallet you choose is compatible with the device you intend to use. If you cannot recover your financial institution without losing your seed/note, you will be unable to utilize your accounts or other money stored inside them. Any credible DeFi wallet would be actively engaged in their Facebook groups.
If you are unsure about purchasing a wallet, look at their social media profiles to see how active they are. Any respectable wallets support public engagements. Some wallets, for example, will not function with Bitcoin, making them unsuitable for someone who uses Bitcoin.
