Overview

Zecwallet lightwalletd is a fork of lightwalletd from the ECC.

It is a backend service that provides a bandwidth-efficient interface to the Zcash blockchain for the Zecwallet light wallet.

Changes from upstream lightwalletd

This version of Zecwallet lightwalletd extends lightwalletd and:

• Adds support for transparent addresses
• Adds several new RPC calls for lightclients
• Lots of perf improvements
  • Replaces SQLite with in-memory cache for Compact Blocks
  • Replace local Txstore, delegating Tx lookups to Zcashd
  • Remove the need for a separate ingestor

Running your own zeclite lightwalletd

0. First, install Go >= 1.11.

1. Generate a TLS self-signed certificate

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

Answer the certificate questions to generate the self-signed certificate

2. You need to run a zcash full node with the following options in zcash.conf

server=1
rpcuser=user
rpcpassword=password
rpcbind=127.0.0.1
rpcport=8232
experimentalfeatures=1
txindex=1
insightexplorer=1

3. Run the frontend:

You'll need to use the certificate generated from step 1

go run cmd/server/main.go -bind-addr 127.0.0.1:9067 -conf-file ~/.zcash/zcash.conf  -tls-cert cert.pem -tls-key key.pem

4. Point the zecwallet-cli to this server

./zecwallet-cli --server https://127.0.0.1:9067 --dangerous
