multi-collateral on a perps protocol is one of those things that's seemingly very simple, but actually very tricky to implement if you want to keep it both decentralized and efficient. What currently exists:
Drift style multi-collateral:
Deposit usdc against alternative collateral types
PROs:
- Simple implementation
CONs:
- You're capital efficiency is capped by the LTV on the lending market
- Rebalancing or swapping collateral becomes trickier
- fee's on funding rates + lending rates
---------------------
Aevo style multi-collateral:
What I like to call just-in-time multi collateral. Users are forced to maintain a usdc balance, whenever this balance goes below a certain threshold aevo swaps a multi-collateral asset into usdc to top up.
PROs:
- higher capital efficiency
CONs:
- entirely centralized
- not really true multi-collateral - a user could deposit 1 BTC but overtime this continuously gets slowly swapped to usdc
