This recovery tool is only meant to be used on legacy BitGo wallets. The current recovery tool can be found in the BitGoJS SDK's 'example' directory.

This open-source, standalone tool is a utility to demonstrate that BitGo wallets can be recovered using the BitGo Account KeyCards and BitGo Disaster Recovery Email information.

In general, users will never need to use this tool. However, if you wish to prove to yourself that BitGo wallets are recoverable without the assistance of BitGo servers, you can use this tool.

The tool will transfer all of your funds from a BitGo wallet to a new address of the user's choosing.

First, the user will provide 3 key pieces of information:

• (1) redeem script for the recovered address
• (2) private keys for signing the transaction
• (1) new address to send the funds to

Upon pressing "Recover My Funds", the tool will do the following:

• Get the list of unspent transactions for the receovered address using the blockchain.info API.

• Create a valid bitcoin transaction within the user's browser to transfer all of the inputs from the recovery address to the new address.

• Sign the transaction.

• Send the bitcoin into the blockchain using the coinb.in API.

• sh build.sh

Just load the file URL in your browser.

We do not recommend using this tool for anything other than emergency situations or proof-of-concept, as it requires you to bring all of your multi-signature keys onto a single machine for signing. If you do use this tool to recover account funds, please discard your recovered wallet(s) and keys after using the tool.
