merkrs

A Rust Merkle tree library compatible with OpenZeppelin's JavaScript implementation.

Features

• [StandardMerkleTree] — ABI-encoded Solidity values with double leaf hashing
• [SimpleMerkleTree] — raw [u8; 32] values with single leaf hashing
• Single-leaf and multi-proof generation / verification
• Serialisation compatible with the OZ JavaScript standard-v1 / simple-v1 formats
• Keccak-256 hashing (Ethereum compatible)

Quick start

use merkrs::{Bytes32, SimpleMerkleTree, simple};

# fn main() -> merkrs::Result<()> {
let values: Vec<Bytes32> = vec![[1u8; 32], [2u8; 32], [3u8; 32], [4u8; 32]];
let tree = SimpleMerkleTree::new(&values, simple::Options::default())?;

let proof = tree.proof(&values[0])?;
assert!(tree.verify_proof(&values[0], &proof)?);
# Ok(())
# }
