To re-process an existing key instead of generating a new one, use -key
.
To generate vanity addresses use -prefix
or the very, very slow -regexp
. There is no GPU support, so you won't get the performance you would get with other implementations (which I have not used or reviewed).
To get script-friendly output use -simple
.
To cross compile simply run e.g. GOOS=linux GOARCH=arm make
.
This is experimental software and it will eat your money, your hard drive and your pets.
Use cases
- offline and paper wallets
- non-Linux amd64 environments (Raspberry Pi, OpenBSD, ...)
- machines without the resources to run a full node
Features
- offline generation of z-address wallets
- vanity addresses
- paper wallet / mnemonic generation
- 300 LoC, easy to review
- pure Go, easy to cross-compile / deploy
Balance management and spending operations are not supported.
Intended workflow
- generate a z-address with
zcash-mini
on a secure machine - optionally write down the 24 words as a paper wallet
- receive Zcash on a t-address in a full node
- send the Zcash to the z-address yourself
- to spend the Zcash, export the private key to a full node
