The biggest issue that comes to mind when choosing a wallet for storing and transacting digital assets in the cryptocurrency ecosystem is who will own the control of the funds and its private key. Based on this key difference, crypto wallets are mainly divided into two categories, which are custodial wallets and non-custodial wallets. There is a well-known saying in the crypto world that the key belongs to the one who owns the asset, and this concept can be seen in the practical form of these two types of wallet systems. A custodial wallet is a type of system where you do not have the secret key or private key of your crypto assets with you, but rather it is stored with a third party or central institution. The wallets inside various popular cryptocurrency exchanges around the world, such as Binance or Coinbase, are the biggest examples of custodial wallets. These wallets are very easy to use and work like our traditional online banking. If a user forgets their password, they can easily recover their account and funds with the help of customer support or via email. However, the main disadvantage is that here you do not have direct sole control over your funds. If the central institution goes bankrupt, gets hacked, or faces any government sanctions, then there is a high risk of all your crypto assets being frozen or lost forever. The complete opposite of this is a non-custodial wallet, where you have 100% ownership and sole control over your crypto assets and their private keys. Software apps like MetaMask or Trust Wallet and hardware devices like Ledger or Trezor are excellent examples of non-custodial wallets. When setting up these wallets, the user is given a 12 or 24-word seed phrase or recovery phrase, which is essentially the root source of all keys. Since your key is not stored in any company or server, it is not possible for a hacker to remotely hack a central server and steal your assets. However, the biggest challenge of this system is its personal responsibility. If you somehow lose your seed phrase or private key, there is no customer support or medium in the world that can return your crores of taka funds, meaning that the entire fund will be lost forever due to your slightest negligence. In short, the main battle between custodial and non-custodial wallets is convenience and freedom. Custodial wallets provide you with easy transactions by freeing you from the fear of forgetting your password, in return for which you have to hand over control of your assets to another institution. On the other hand, non-custodial wallets provide you with financial freedom and maximum security free from hacking, in return for which you have to shoulder the full responsibility of storing your keys. Therefore, those who trade regularly usually prefer custodial wallets, and those who want to store large amounts of crypto for the long term choose non-custodial wallets.
