Module pool_derivation 

SPL interface PDA derivation utilities for Light Protocol.

This module provides functions to derive SPL interface PDAs (token pools) for both regular and restricted mints. Restricted mints (those with Pausable, PermanentDelegate, TransferFeeConfig, TransferHook, or DefaultAccountState extensions) use a different derivation path to prevent accidental compression via legacy anchor instructions.

Constants

NUM_MAX_POOL_ACCOUNTS

Maximum number of pool accounts per mint.

Functions

find_spl_interface_pda

Find the SPL interface PDA for a given mint (index 0).

find_spl_interface_pda_with_index

Find the SPL interface PDA for a given mint and index.

get_spl_interface_pda

Get the SPL interface PDA address for a given mint (index 0).

has_restricted_extensions

Check if a mint has any restricted extensions.

is_valid_spl_interface_pda

Validate that an SPL interface PDA is correctly derived.
