Pure Move language implementation of U256 numbers.
Would be nice to help with the TODO list, you can see it in the header comment.
Supported features:
- mul
- div
- add
- sub
- shift left
- shift right
- bitwise and, xor, or
- compare
- if math overflows the contract crashes with abort code.
The audit still missed, so use at your own risk.

Add to Move.toml:
[dependencies.U256]
git = "https://github.com/pontem-network/U256.git"
rev = "v0.3.9"And then use in code:
use u256::u256;
...
let a = u256::from_u128(10);
let b = u256::from_u64(10);
let c = u256::add(a, b);
let z = u256::as_u128(c);Apache 2.0
