"No Interoperability between Digital Wallet Payments ?
User Pain Points:
Lack of Interoperability: Digital wallets operate in silos, forcing users to rely on inefficient workarounds, such as transferring funds to a bank account and then to another wallet, resulting in delays and extra effort.
Time-Consuming Process: Current methods to move money between wallets are tedious, often taking 1-3 business days, which can be especially inconvenient for time-sensitive transactions.
