Struct LpNft

Source 
pub struct LpNft { /* private fields */ }
Expand description

The denomination of an LPNFT tracking both ownership and state of a position.

Tracking the state as part of the LPNFT means that all LP-related actions can be authorized by spending funds: a state transition (e.g., closing a position) is modeled as spending an “open position LPNFT” and minting a “closed position LPNFT” for the same (globally unique) position ID.

This means that the LP mechanics can be agnostic to the mechanism used to record custody and spend authorization. For instance, they can be recorded in the shielded pool, where custody is based on off-chain keys, or they could be recorded in a programmatic on-chain account (in the future, e.g., to support interchain accounts). This also means that LP-related actions don’t require any cryptographic implementation (proofs, signatures, etc), other than hooking into the balance commitment mechanism used for transaction balances.
