The size of the DeFi lending market continues to expand, but the design logic of traditional lending protocols is becoming increasingly rigid. Most protocols follow the same pattern: users choose a mainstream asset (usually ETH or BTC) as collateral, the protocol mints corresponding stablecoins for borrowing, and liquidation thresholds and risk parameters are all built around a single asset. This system is simple and clear, and risk control is easy to manage—just monitor one price source.

However, in reality, user wallets are no longer like that. Stablecoins, mainstream coins, niche tokens, and even on-chain versions of real-world assets are all mixed together. When borrowing, users are forced to sell other assets to exchange for collateral accepted by the protocol, or they simply give up on borrowing. This dilemma limits the efficiency of users' funds.

Some projects are trying to change this situation. Their idea is to allow multiple assets to serve as collateral simultaneously. Users don’t need to exchange assets; they can directly use multiple tokens in their wallets as collateral to mint a stablecoin pegged to 1 USD, and also offer interest-bearing versions for advanced users. Essentially, this upgrades traditional single-asset lending into a more flexible multi-asset portfolio framework. This design can better accommodate the actual asset holdings of users, allowing idle assets to also generate lending value.
