Last Resort Only

What is the Emergency Recovery Tool?

In Vultisig, the private key never exists during normal operation—this significantly improves security since there's no private key to be extracted or stolen.

However, it is possible to recombine vault shares and generate the private key for use in other wallets. Scripts are provided for this purpose if Vultisig software ever becomes unavailable.

Recommended: Vault Share Decoder

For most users, the community-built Vault Share Decoder is the easiest way to recover:

• Website: https://share-decoder.vultisig.com

• Repository: GitHub

This tool provides a user-friendly interface to decode vault shares and recover private keys without requiring developer tools.

The Vault Share Decoder is the preferred method for emergency recovery. Only use the CLI/Web options below if the community tool is unavailable.
