ZExCavator v0 Released!

I am pleased to announce that Zingo Labs has finished ZExCavator v0.0.1.

This tool has a minimal set of functionality focused on recovering ZEC from old wallet files.

The engine that ZExCavator is built around is a new implementation of sync, “pepper-sync” that leverages librustzcash primitives like sync prioritization, to provide uniquely fast sync, in many scenarios.

While ZExCavator can already efficiently recover funds in certain cases, we have more work to do to reach Version 1.0.0.

ZExCavator v1 Planned

In particular we need to extend the synchronization algorithm to efficiently handle large numbers of non-standard HD Sapling Keys. This will account for the creative generation of new addresses that was implemented in ZecWallet.

Beyond that necessary enhancement, we also hope to offer ZeWIF integrations to ease data transfer between Zingo Labs wallets and other wallets:

Altogether if we receive funding for a completion grant we’ll:

  • extend pepper-sync and ZExCavator to handle non-standard multi-key sync

  • offer a ZeWIF adapter crate that

  • publish cross-wallet synchronization benchmarks to provide the community with insight into modern sync performance
