Security Mechanisms
In terms of security, digital banking wallets and crypto wallets differ from each other sharply. Digital banking wallets rely upon known means of security—passwords, two-factor security, biometrics—and rely upon the traditional, established security measures of standard banking, which also has a larger network for fraud detection, payment reversal, and troubleshooting.
Card payments made from a digital banking wallet are also tokenised, meaning services like Apple Pay and Google Pay pass a substitute number to the merchant instead of the real card number, and a disputed charge can still be clawed back through a chargeback.
Crypto wallets, by contrast, put the whole security burden on key storage. A hot wallet stays connected to the internet and is convenient for frequent trading but permanently exposed, whereas a cold wallet, usually a hardware device such as a Ledger, keeps the keys offline and suits balances held for the long term.
There is no chargeback and no fraud team on a blockchain: once a transaction is confirmed to a wallet address, it cannot be reversed, so a mistyped address is an unrecoverable loss rather than a support ticket.
Transaction Types
As far as cash and credit transactions are concerned, where regular wallets implement debit and credit, there are none. For example, a credit transaction is money a consumer does not currently have available to them; instead, they intend to repay the creditor at a future date.
Yet, with digital currency, this is not applicable. Where a wallet transaction (or exchange) occurs, a consumer automatically debits what they have available to them, purchasing the standard equity price.
The transactions each type of wallet facilitates reveal the type of worlds in which they operate. A digital banking wallet facilitates transactions that belong to a money-based, fiat-operating world with a mutual socio-economic reality—retail world purchases, payments for utility bills, and wallet-to-wallet transactions, all requiring a connection to a global banking entity.
On the other hand, a crypto wallet creates transactions that offer value to a decentralized, peer-to-peer universe. Cryptocurrency transactions occur between wallet addresses—no intermediary required—which suggests that they exist in any and every dimension, not restricted to the location of the participants, whether in the physical or digital realm.
In addition, crypto wallets connect holders to smart contracts—essentially, programmable money—existing in their decentralized universe.
Cost is where the two diverge most visibly for small payments: a card payment from a digital banking wallet is usually free to the payer, whereas a crypto transfer carries a network gas fee that is set by demand on the blockchain and can exceed the value of a small purchase.
Regulatory Oversight
The regulatory environment for digital wallets is somewhat mixed. Digital banking wallets operate under the same regulatory atmosphere as any other financial product—KYC and AML required.
As such, this means more regulatory protections for the consumer and more channels for recourse in the event of malfeasance; however, it also creates a more complicated environment for growing and expanding with more compliance hurdles.
In practice this shows up in two ways an everyday user will notice: money held with a licensed bank is covered by a deposit guarantee scheme up to a set limit if the institution fails, and every payment triggers strong customer authentication under PSD2, which is why a bank app asks for a second confirmation on almost every transaction.
By contrast, crypto wallets operate in a legal limbo. Depending on the nation, cryptocurrency is not considered legal tender across the board. For the ultimate user, this is an advantage or a drawback. It allows practically anyone easy access; however, it also offers no guarantee that certain protections will be available.
That gap is narrowing in Europe, where the Markets in Crypto-Assets Regulation now licenses crypto-asset service providers and sets rules for custody and stablecoins, though it still does not extend deposit protection to a self-custody wallet.
