Offline BIP32 HD wallet and vanity address generator for ZCash.
Currently returns the first address associated with m/0'/0/0 (hardened key for account 0/external account)
##Pre-requisites
- Golang 1.7.3 (lower versions may work but this is what I developed with)
- Git
##Build
go get -u github.com/btcsuite/btcutil
go get -u github.com/blackkeyboard/mneumonic
go install github.com/blackkeyboard/zgenerate
go install github.com/blackkeyboard/zgenerate/zretrieve
##Update an Existing Install
go clean github.com/blackkeyboard/zgenerate
go install github.com/blackkeyboard/zgenerate
go install github.com/blackkeyboard/zgenerate/zretrieve
##Usage To generate a wallet:
zgenerate [-t] [-n 1]
Options
-t generate testnet addresses
-n number of addresses to generate. Defaults to 1
To retrieve addresses generated from your HD wallet:
zretrieve -passphrase=<passphrase> [-t] [-n 1] [-match="regex string"] [-i]
Options
-t generate testnet addresses
-n number of addresses to retrieve. Defaults to 1
-match regex string to search for in the address
-i case insensitive string matching
eg. Search case insensitive for a vanity address which starts with the string "t1jl"
zretrieve -passphrase="board start difference answer blossom roll powerful million rough butterfly bedroom beam" -match "^t1jl" -i
Note: The maximum number of addresses that can be searched given a wallet passphrase is restricted to 4,294,967,295 (unsigned 32 bit integer). Depending on your version of Go, case insensitive matching may be slow. golang/go#13288.
To import the private key into ZCash:
./zcash-cli importprivkey "private_key_from_zgenerate"
Zcashd will automatically rescan the blockchain for transactions
