Your funds can be recovered with the help of a BCH miner. They use your information to create a transaction on your behalf and include it in a block that they find (for a fee). We have had success in the past utilizing BTC.com’s recovery service here: https://bch.btc.com/docs/help/bch_segwit_recovery. *This automated service is discontinued but we've heard from users that they've received recovery assistance by emailing admin@btc.com*
They require three pieces of information in order to recover your funds.
-
Bitcoin Cash transaction hash on Segwit address
-
The wallet/exchange that sent the funds can provide this information
-
-
Public key for this Segwit address
-
The extended public key of a BTC Eidoo wallet can be retrieved using the 12 words (seed) of the backup:
-
Connect to the site https://iancoleman.io/bip39/ (for more security the tool on this site can also be used in offline mode)
-
In the “Mnemonic” section enter the 12 words in box “BIP39 Mnemonic” and select BTC-Bitcoin inside the Coin
-
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 -
Check that all data entered is correct and transferred to the section below “Derived Addresses”
-
If all the data is correct you will find the public master key in the section "Account Extended Public Key"
-
-
-
Address to receive Bitcoin Cash
Enter these three pieces of information into the BTC.com form and they will attempt to recover your funds.
