Vaults & Strategies

Our vaults are based on audited and battle tested contracts, with added features and security considerations while minimizing gas costs in both deployment as well as user usage.

XpandrUnityVault: Immutable, streamlined, security & gas considerate unified Vault + Strategy contract. Includes: 0% withdraw fee default / Vault profit in USD / Deposit & harvest buffers / Timestamp & Slippage protection.

The Vault side of the contract is based upon the audited ERC4626 tokenized vault standard, with added strategy embedded in it. This removes risk from external calls to a secondary strategy that could be switched or upgradeable proxy contract while at the same time reducing overall gas costs. The vault operates with a 0% withdraw fee. To prevent economic/spam attacks, both deposit and harvest functions have an adjustable buffer between 10-30 minutes. Deposit buffer acts on same user deposits and the harvester's upon anyone calling it. It is still possible to turn on withdraw fees to a max value of 0.1% in the event that the buffers wouldn't suffice and the economic attacks persisted to fully negate any attempt at value extraction. This fee stays in the vault for users still deposited, it does not go to the protocol. While the ERC4626 standard allows 3rd parties to withdraw for a user if given approval, due to security considerations, we've removed this from Xpandr's implementation. Only receipt holder can withdraw & to his own address. To accommodate vaulting pools that have a dynamic nature beyond UnityVault's setters, there's also a 2 piece version of this vault. XpandrTakeProfit: A version of the vault where instead of re-investing rewards back into the LP, they're sold for another asset such as USDC, claimable by depositors. A way of hedging rewards against the market and another option on Xpandr to manage your liquidity.
