Crate smt_circom 

Sparse Merkle Tree, compatible with circom proofs.

This crate implements a Poseidon-based Sparse Merkle Tree suitable for generating witnesses/proofs for circom circuits. Nodes are persisted via a pluggable NodeStore and keyed/hashed as 32-byte big-endian field elements over BN254.
