1. Searching through the block: Initially, we encountered the challenge of sifting through extensive block histories to gather all commitments. To streamline this process, we optimized our approach by narrowing our block search range to a maximum of 1000, simplifying both the search and computational aspects significantly.

2. ZK Dependency Issue: While incorporating ZK-Snarks to generate the proof in the front end, we encountered numerous dependency issues. Seeking assistance from various online resources and engaging in extensive debugging efforts, we successfully resolved these issues.

3. Hash Function Issue: Initially, when constructing the Merkle tree for chains such as Polygon and Harmony, we employed Poseidon hashing. However, we encountered compatibility issues with ZK-EVM based chains. To address this, we had to switch to a specific version of the Poseidon hash function that was designed to be ZK-friendly.
