#Vaulta 1. Core Features of Web3 Banking: A Paradigm Shift in On-Chain Finance**

Web3 banking is not a simple digitalization of traditional banking, but a deep integration of decentralized finance (DeFi) based on blockchain technology with traditional banking services. Its core features include:

- **Self-Custody and Transparency of Accounts**: Users have complete control over their assets through on-chain accounts (such as Fiat24's Arbitrum on-chain bank account), with all transaction records on the blockchain, achieving transparency and traceability.

- **Seamless Interaction between Fiat and Crypto Assets**: Through smart contract protocol layers (such as Fiat24's Fiat Layer Protocol), users can directly exchange crypto assets for fiat currency, conduct cross-border remittances, and even link virtual Visa cards for daily consumption right within their wallets.
