We were able to push forward a lot of progress, including that we were able to develop a Metamask snap (deployed at nullifier.xyz) and push an independent Javascript implementation that discovered an overflow bug in both of the Rust implementations! We also released a circom version, and received a V2 proposal from Poseidon. We also started working on a Ledger implementation with two new teammates (as of April 2023). We also are building towards a burner wallet integration and EIP, both of which we are actively polishing drafts on in collaboration with EF PSE and hope to have published once the halo2 proof is done.
