A multichain, multiprotocol vault has been programmed to accept deposits on one chain and route capital across multiple protocols and, when appropriate, multiple chains for the best risk-adjusted yield. The end user sees a single balance, and sees where their assets are being allocated.
Veda vaults can be programmed to hold positions across any of the 20+ chains we support, allocated across some subset of 35 protocols. However, most multiprotocol vaults allocate to 2-5 protocols at any given time as part of a predetermined yield strategy.
The advantages are higher performance and superior durability. Single-protocol vaults are exposed when that protocol's yield compresses or its risk profile shifts. Multichain, multiprotocol vaults rebalance and adapt.
