The Dynamic Fee Sharing program allows for the creation of fee vaults where collected fees can be automatically distributed among multiple recipients based on predetermined share allocations.

​
Key Features

Secure Fee Management

On-chain fee collection and distribution with support for both SPL tokens and Token-2022 tokens. Features precise mathematical calculations with overflow protection and immutable share configurations after initialization.

Multi-User Support

Support for 2-5 users per fee vault with configurable share allocations for each user. Includes individual claim tracking to prevent double claims and user-specific checkpoints for accurate fee distribution.

Flexible Fee Distribution

Real-time fee accumulation with pro-rata distribution based on share percentages. Uses lazy evaluation for gas efficiency and supports partial funding and claiming.
