# lbcwallet
|
||||
|
||||
lbcwallet implements HD Wallet functionality which conforms to
|
||||
[BIP0032](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki),
|
||||
[BIP0043](https://github.com/bitcoin/bips/blob/master/bip-0043.mediawiki),
|
||||
and [BIP0044](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki).
|
||||
lbcwallet is a daemon, which provides lbry wallet functionality for a
|
||||
single user.
|
||||
|
||||
Public and private keys are derived using the hierarchical
|
||||
deterministic format described by
|
||||
[BIP0032](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki).
|
||||
Unencrypted private keys are not supported and are never written to disk.
|
||||
|
||||
lbcwallet uses the `m/44'/<coin type>'/<account>'/<branch>/<address index>`
|
||||
HD path for all derived addresses, as described by
|
||||
[BIP0044](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki).
|
||||
|
||||
Due to the sensitive nature of public data in a BIP0032 wallet,
|
||||
lbcwallet provides the option of encrypting not just private keys, but
|
||||
public data as well. This is intended to thwart privacy risks where a
|
||||
wallet file is compromised without exposing all current and future
|
||||
addresses (public keys) managed by the wallet. While access to this
|
||||
information would not allow an attacker to spend or steal coins, it
|
||||
does mean they could track all transactions involving your addresses
|
||||
and therefore know your exact balance. In a future release, public data
|
||||
encryption will extend to transactions as well.
|
||||
|
||||
The JSON-RPC server exists to ease the migration of wallet applications
|
||||
from Core, but complete compatibility is not guaranteed. Some portions of
|
||||
the API (and especially accounts) have to work differently due to other
|
||||
design decisions (mostly due to BIP0044). However, if you find a
|
||||
compatibility issue and feel that it could be reasonably supported, please
|
||||
report an issue. This server is enabled by default.

## Build from Source Code
|
||||
## Requirements
|
||||
|
||||
Requires [Go](http://golang.org) 1.19 or newer. Install Go according to its [installation instructions](http://golang.org/doc/install).
|
||||
- [Go](http://golang.org) 1.16 or newer.
|
||||
|
||||
- `lbcwallet` is not an SPV client and requires connecting to a local or remote
|
||||
`lbcd` for asynchronous blockchain queries and notifications over websockets.
|
||||
|
||||
Full installation instructions can be found [here](https://github.com/lbryio/lbcd).

## To Build lbcwallet, lbcd, and lbcctl from Source
|
||||
|
||||
Install Go according to its [installation instructions](http://golang.org/doc/install).
|

||||
Build `lbcwallet`

## **lbcd** & **lbcwallet**
|
||||
To make the quick start guide self-contained, here's how we can build the `lbcd` and `lbcctl`
|
||||
|
||||
`lbcwallet` is not an SPV client and requires connecting to a `lbcd` node for asynchronous blockchain queries and notifications over websockets.
|
||||
``` sh
|
||||
git clone https://github.com/lbryio/lbcd
|
||||
cd lbcd
|
||||
|
||||
lbcwallet can serve wallet related RPCs and proxy lbcd RPCs to the assocated lbcd. It's sufficient for a user to connect just the **lbcwallet** instead of both.

||||

# build lbcctl
|
||||
go build ./cmd/lbcctl
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
Create a new wallet with a randomly generated seed or an existing one.
|
||||
The first time running the `lbcwallet` we need to create a new wallet.
|
||||
|
||||
``` sh
|
||||
lbcwallet --create
|
||||
|
||||
Do you have an existing wallet seed you want to use? (n/no/y/yes) [no]: no
|
||||
Your wallet generation seed is: 3d005498ad5e9b7439b857249e328ec34e21845b7d1a7d2a5641d4050c02d0da
|
||||
./lbcwallet --create
|
||||
```
|
||||
|
||||
The created wallet protects the seed with a default passphrase (`"passphrase"`), which can be override with `-p` option:
|
||||
Start a local instance of `lbcd` and have the `lbcwallet` connecting to it.
|
||||
|
||||
``` sh
|
||||
lbcwallet --create -p my-passphrase
|
||||
# Start a lbcd with its RPC credentials
|
||||
./lbcd --txindex --rpcuser=rpcuser --rpcpass=rpcpass
|
||||
|
||||
# Start a lbcwallet with its RPC credentials along with the lbcd's RPC credentials
|
||||
# The default lbcd instance to conect to is already localhost:9245 so we don't need to specify it explicitly here.
|
||||
./lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass # --rpcconnect=localhost:9245
|
||||
|
||||
#
|
||||
# rpcuser/rpcpass rpcuser/rpcpass
|
||||
# lbcctl <-------------------> lbcwallet <--------------------> lbcd
|
||||
# RPC port 9244 RPC port 9245
|
||||
#
|
||||
```
|
||||
|
||||
Start wallet server, and connect it to a lbcd instance.
|
||||
|
||||
``` sh
|
||||
lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass # --rpcconnect=localhost:9245
|
||||
./lbcd --txindex --rpcuser=rpcuser --rpcpass=rpcpass
|
||||
|
||||
./lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass
|
||||
|
||||
#
|
||||
# rpcuser/rpcpass rpcuser/rpcpass
|
||||
# lbcctl <-------------------> lbcwallet <--------------------> lbcd
|
||||
# RPC port 9244 RPC port 9245
|
||||
#
|
||||
```
|
||||
|
||||
At startup, the wallet will try to unlock itself with the default passphrase (`passphrase`) or an user provided one (using `-p` option).
|
||||
Note:
|
||||
|
||||
If the passphrase does not match, the wallet remains locked. User can lock/unlock the wallet using `walletlock` and `walletpassphrase` RPCs.
|
||||
- `lbcd` and `lbcwallet` implements two disjoint sets of RPCs.
|
||||
- `lbcd` serves RPC on port 9245 while `lbcwallet` on port 9244.
|
||||
- `lbcwallet` can proxy non-wallet RPCs to its associated `lbcd`.
|
||||
|
||||
Examples of using `lbcctl` to interact with the setup via RPCs:
|
||||
|
||||
1. Calling non-wallet RPC directly on lbcd:
|
||||
|
||||
``` sh
|
||||
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass getblockcount
|
||||
|
||||
#
|
||||
# lbcctl <-- getblockcount() --> lbcd
|
||||
# RPC port 9245 (handled)
|
||||
#
|
||||
```
|
||||
|
||||
2. Calling wallet RPC on lbcwallet (using `--wallet`)
|
||||
|
||||
``` sh
|
||||
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass --wallet getbalance
|
||||
|
||||
#
|
||||
# lbcctl <-- getbalance() --> lbcwallet
|
||||
# RPC port 9244 (handled)
|
||||
#
|
||||
```
|
||||
|
||||
3. Calling non-wallet RPC on lbcwallet, which proxies it to lbcd:
|
||||
|
||||
``` sh
|
||||
./lbcctl --rpcuser=rpcuser --rpcpass=rpcpass --wallet getblockcount
|
||||
|
||||
#
|
||||
# lbcctl <-- getblockcount() --> lbcwallet <-- getblockcount() --> lbcd
|
||||
# RPC port 9244 (proxied) RPC port 9245
|
||||
#
|
||||
```
|
||||

||||

Examples
|
||||
|

lbcwallet --rpcuser=rpcuser --rpcpass=rpcpass -p my_passphrase

||||
./lbcctl getblockcount # port 9245

./lbcctl --wallet getblockcount # port 9244
|
||||
./lbcctl --testnet getblockcount # port 19245
|
||||
./lbcctl --wallet --regtest getblockcount # port 29244
