To complete this process on a UTXO-based network, it's important to understand how these wallets work — and why a few extra steps are needed compared to account-based blockchains.What is a UTXO? A UTXO (Unspent Transaction Output) is a discrete chunk of digital assets locked to a specific address, waiting to be spent. Unlike account-based blockchains (such as Ethereum), UTXO-based networks don't store a single balance per account.

Interest on borrowed funds is calculated based on the customer's interest-bearing liability and is recorded every hour on the hour, starting from 0:00. For example, if a customer borrows crypto at 22:55, no interest is recorded at that time. At 23:00, the customer's interest is calculated based on the interest-bearing liability, and the interest is deducted at 23:00. If the customer repays the borrowed cryptos at 22:57, that borrowing will not incur any interest.3.
