The private key of a BTC Eidoo wallet can be retrieved using the 12 words (seed) of the backup:
1. Connect to the site https://iancoleman.io/bip39/ (for more security the tool on this site can also be used in offline mode)
2. In the “Mnemonic” section enter the 12 words in box “BIP39 Mnemonic” and select BTC-Bitcoin inside the Coin
3. In the “Derivation Path” section select the “BIP49” tab and starting from the first line enter the following values:
Purpose -> 49
Coin -> 0
Account -> 0
External/Internal -> 0 or 1
4. Check that all data entered is correct and transferred to the section below “Derived Addresses”
5. If all the data is correct you will find in the “Derived Addresses” section the private keys of all the BTC addresses used in the Private Key column.
N.B. Eidoo is based on an HD (Hierarchical Deterministic) framework, a privacy-focused method for generating and managing addresses. When a BTC address receives an incoming transaction, a new address will be automatically generated and displayed.
This means that the user will have to iterate all the addresses and retrieve all the private keys of the addresses used in order to recover the entire amount of BTC in his possession.
This is necessary, in order to maintain the high standard of security that we want to offer to our users.
