Warp Zcash Wallet Library

Appearance

Zcashd ​

Configuration ​

If you have zcashd compiled from source, it will be in the src folder of the project root.

We want to run the server in Regtest. In this mode, the server creates and connects to its own Blockchain (independent from the main chain). Therefore, you have full control over when blocks are created and which transactions are included.

INFO

On regtest, ZEC has no value.

  1. First create a directory (for example regtest_dir) where you will put the configuration and data files
  2. In this directory, create a zcash.conf file with the following content:
regtest=1
rpcuser=a
rpcpassword=a
nuparams=c2d6d0b4:1
rpcallowip=192.168.0.0/24
experimentalfeatures=1
lightwalletd=1
txindex=1
  • The rpcuser and rpcpassword can be anything you want. Don't forget to activate regtest otherwise the server will connect to the mainnet.
  • nuparam=c2d6d0b4:1 tells the server that NU-5 (the Orchard Network Upgrade) should be activated at Block #1.
  • rpcallowip is the network mask that restricts which clients can connect. In your local net, it is often 192.168.0.0/24.
  • The last 3 options are for lightwalletd

Now start the server with the command:

$ ./src/zcashd --datadir=regtest_dir --daemon

(assuming you used regtest_dir)

WARNING

Do not type the $ sign. It just indicates that this line is your input vs the output of the command.

After a short while, the server should give you back control of the command line.

TIP

The regtest_dir should have a regtest sub directory and the zcash.conf file.

Check ​

We check that the server is running properly by sending a simple command to it.

$ ./src/zcash-cli --datadir=regtest_dir getinfo

It should return something like:

{
  "version": 5080050,
  "build": "v5.8.0",
  "subversion": "/MagicBean:5.8.0/",
  "protocolversion": 170100,
  "walletversion": 60000,
  "balance": 0.00000000,
  "blocks": 0,                       <-------- Check this
  "timeoffset": 0,
  "connections": 0,
  "proxy": "",
  "difficulty": 1,
  "testnet": false,
  "keypoololdest": 1727010648,
  "keypoolsize": 101,
  "paytxfee": 0.00000000,
  "relayfee": 0.00000100,
  "errors": "",
  "errorstimestamp": 1727010650
}

A block height of 0 indicates that we are running on our blockchain since we are still at the genesis.

Next, we'll setup our Zcash Warp wallet.
