What's unique about Extended’s native money market. With multi-asset collateral now live, @extendedapp users can deposit ETH and wBTC (with USDT and EURC coming shortly) and use them as margin to trade perpetuals. When a user's USDC balance goes negative, borrowing is triggered automatically with the Extended Vault serving as the primary lender. The key difference is how borrowing rates work. Traditional crypto money markets typically operate through isolated lending pools, where interest rates depend only on utilisation of a specific pool. Collateral risk is managed separately through haircuts and borrowing limits. Extended's setup is fundamentally different. The Vault lends against multiple collateral assets simultaneously, while borrowing demand emerges dynamically from unrealised PnL. In this environment static global borrowing caps are not practical. As a result borrowing rates depend on two dimensions: - overall vault utilisation - utilisation against a specific collateral asset. This means borrowing USDC against ETH can be cheaper than borrowing against BTC if system-wide exposure to ETH is lower. The second layer is how borrowing is allocated. When a user has multiple collateral assets, the system automatically routes borrowing through the lowest-rate collateral first, minimising the effective cost of capital. Example: if a user has a negative USDC balance backed by both ETH and wBTC collateral, and ETH borrow rates are lower than BTC, the system will allocate borrowing against ETH first before routing the remainder against BTC, continuously reducing the effective cost of capital. The result is a system where: - users automatically receive the cheapest borrowing allocation across their collateral portfolio - Extended maintains granular risk control over exposure to different collateral assets backing borrowed USDC - vault depositors earn additional yield directly from trading activity.
