Multisig wallets are an increasingly popular bitcoin (BTC) storage option, with over 20% of BTC storage options now multisig, up from 15% in 2020. Unfortunately, the Block.io wallet is no longer one of these options.
Block.io is a Bitcoin wallet service created in 2015 and offered alongside an API by the same name. The API was for developers, but people could also utilize the platform to store and transact BTC, Litecoin (LTC), and Dogecoin (DOGE) in multisig wallets.
Recently, Block.io has rebranded to Sochain. This rebrand came with some new products, but most importantly, it saw the discontinuation of others; like the wallet. So Block.io’s crypto wallet can no longer be used to manage assets.
Ideally, most users transferred their crypto to other wallets before Block.io went out of service. But what about those that didn’t?
Well, here is how you can recover your Block.io wallet.
How did the Block.io Wallet Work and What Happened?
At its core, Block.io worked like any other crypto wallet, using a combination of public and private keys to manage assets. But unlike most wallets, all Block.io accounts were multisig, meaning a transaction required multiple signatures before it could go through.
In this case, you needed at least two signatures to withdraw funds, though an account could have up to 5 signatures. One signature was always in Block.io’s possession, but you could enable up to four additional signatures.
Block.io’s wallet service was discontinued on short notice causing many people to lose access to their coins. And with the company offering little in ways of customer service, affected users need alternative solutions.
Crypto Wallet Recovery Options for Block.io
Usually, recovering a crypto wallet is straightforward. You just download another wallet, like Exodus or Electrum, and import your keys. But, with Block.io being a multisig wallet, a few complications make this option unviable.
Block.io initially provided code to sweep wallets, but this program is outdated, may require paid APIs, and you have to build the back end yourself. This makes recovery extremely difficult if you’re not a developer.
The other option is to use your recovery document.
Recovery Document
When the wallet was created, Block.io gave users a PDF with recovery instructions and tools. It contains a lot of information— here is the data relevant for recovery:
- Network: Blockchain network for the account.
Example: Bitcoin - BIP32 Private Key: An extended private key that can derive all child private keys and public keys.
Example:xprv9s21ZrQH143K36NNa3nK934KWw2Lj4Rty8HTCo8eAXSk5QLfcjeLgRpnaHBJii43yZ2WvNNduqUvtXFNkPeffxGe8Nm7EBVKaTJy2ZEU5T2 - Second Private Key: A second private key associated with the second public key, typically used in multi-signature wallets.
Example:L5dE3h64TR2mKbSJ69Na2fRWbgGSboWnDPXWLSDL8jUyVrtFZFYC - P2SH/P2WSH-over-P2SH/P2WSH Address (i=0): A sample address for a Pay-to-Script-Hash (P2SH) or Pay-to-Witness-Script-Hash (P2WSH) wallet, derived for index i=0.
Example:3F86Fa4au811yuQ7HC1AfGnsGHYM7GEyh9
Here is some other info contained in the document:
- BIP32 Derivation Path: The specific path used to derive child keys from the master key in an HD wallet.
Example:m/i/0 - Redeem Script Format: The script that defines the conditions for spending funds in a multi-signature wallet.
Example:2 BIP32_public_key_for_node_i 02822284fff7ff8a06ecc8e952c851fad8847cad33fdb062ab3b0ff501e6124da3 2 OP_CHECKMULTISIG - Test Redeem Script (i=0): A sample redeem script for testing purposes, showing how funds would be redeemed for index i=0.
