I cover the core challenges of distributing dividends proportionally, preserving historical dividends, and doing this efficiently without looping over holders. I detail the smart contract's checkpoint accounting pattern, which allows for accurate dividend tracking during token minting, transferring, and burning. I also clarify how to calculate claimable amounts during withdrawals. Please review the implementation and verify that all test cases pass.
