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
