# Solana NoStd BigModExp

A more efficient implementation of Big Number Modular Exponentiation for SVM.

# Installation

```cargo add solana-nostd-big-mod-exp```

# Features

- Makes use of MaybeUninit to skip zero allocations
- Implements a fixed size `big_mod_exp_fixed` function to avoid heap allocations
