hopper-distribute

Dust-safe proportional splits and fee extraction for Hopper programs. Largest-remainder distribution, basis-point fees, flat fees, and exact conservation. Pure functions, no_std, no_alloc, and BPF-safe.

Part of the Hopper framework.

The math is integer-only: split outputs always sum to the input, and fee extraction always returns (net, fee) where net + fee == amount.

use hopper_distribute::{extract_fee, proportional_split};

let shares = [10_u64, 30, 60];
let mut out = [0_u64; 3];
proportional_split(1_000, &shares, &mut out)?;
// out == [100, 300, 600], sum == 1_000

let (net, fee) = extract_fee(1_000_000, 30, 0)?; // 30 bps == 0.30%
