Weft makes available some extra features

Native Support for LSU and Unstaking NFTs

Weft provides native support for all current and future Liquid Staking Units (LSUs) on the Radix Network. Since LSUs are integrated directly into the Radix ledger, there is always an option to redeem them for their corresponding XRD value. To keep things straightforward, LSU risk configurations match those of XRD, meaning that LSUs are treated similarly to XRD when checking Collateralized Debt Position (CDP) health. Although LSUs use the XRD configuration, their value is actually based on redeemable XRD.

When an LSU is unstaked, a cooldown period of approximately 7 days applies. During this time, the unstaker receives a Claim NFT, which can be used to claim the underlying XRD once the cooldown is over. Weft also supports this Claim NFT natively, just as it does with LSUs, because the Radix ledger provides all the necessary information to access the underlying XRD value.

Pools configuration versioning

Weft V2 introduces configuration auto versioning by keeping a history of configuration each time there is a change in risk parameters like LTV and risk index. In addition to that, the current configuration version is kept in CDP NFT metadata on each operation. That allow CDP position to be linked to active configuration during their last edit. So even if there is a configuration change, the previous configuration will be kept for the CDP health checking process until the user updates his positions.

As some change can be driven by issues, In case of a critical change, configuration can have an expiry set by governance.

Flash loan

A flash loan is a type of loan where a user borrows assets with no upfront collateral and returns the borrowed assets within the same ledger transaction. Weft makes available flash loans on all lending pools.

Collateral flash operations

Inspired by flash loan, flash collateral operation allows users to remove fungible or non-fungible collaterals from a CDP without checking its health upfront. Instead, the health is checked once the user instructs the protocol to do so. In that case, the only important state is a healthy CDP, if that is the case, the transaction will go through otherwise the transaction will fail.

This feature enables interesting use cases. One is Collateral swap, as there is no flash loan on collateral pools, flash collateral operation may come handy for collateral swap without repaying attached loan.

Another use case is about NFT Collateral. A staking receipt could be flash withdrawn to increase or reduce current stake and add back to the CDP all without repaying bounded loans.
