jaxwallet

jaxwallet is a daemon handling bitcoin wallet functionality for a single user. It acts as both an RPC client to jaxnetd and an RPC server for wallet clients and legacy RPC applications.

1. Getting Started
2. RPC Usage

Public and private keys are derived using the hierarchical deterministic format described by BIP0032. Unencrypted private keys are not supported and are never written to disk. jaxwallet uses the m/44'/<coin type>'/<account>'/<branch>/<address index> HD path for all derived addresses, as described by BIP0044.

Due to the sensitive nature of public data in a BIP0032 wallet, jaxwallet 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.

jaxwallet is not an SPV client and requires connecting to a local or remote jaxnetd instance for asynchronous blockchain queries and notifications over websockets. Full jaxnetd installation instructions can be found here. An alternative SPV mode that is compatible with jaxnetd is planned for a future release.

A legacy JSON-RPC server mostly compatible with Bitcoin Core

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.

Requirements

Go 1.17 or newer.

Building, installation and updating

go version
go env GOROOT GOPATH

NOTE: The GOROOT and GOPATH above must not be the same path. It is recommended that GOPATH is set to a directory in your home directory such as ~/goprojects to avoid write permission issues. It is also recommended to add $GOPATH/bin to your PATH at this point.

• Run the following commands to obtain jaxwallet, all dependencies, and install it:

git clone https://gitlab.com/jaxnet/jaxwallet.git
cd jaxwallet
go build -v . 
go build -v . ./cmd/...

Now you can use ./jaxwallet binary.

Alternative way. You can install jaxwalletd in $GOPATH/bin.

go install -v . ./cmd/...

• jaxwallet (and utilities) will now be installed in $GOPATH/bin. If you did not already add the bin directory to your system path during Go installation, we recommend you do so now.

Updating

Linux/BSD/MacOSX/POSIX - Build from Source

• Run the following commands to update jaxnetd, all dependencies, and install it:

cd jaxwallet
git pull
go build -v . 
go build -v . ./cmd/...
## OR install binaries to $GOPATH/bin
go install -v . ./cmd/...

Now you can use ./jaxwallet binary.

Getting Started

The following instructions detail how to get started with jaxwallet connecting to a localhost jaxnetd.

1. Setup jaxnetd node and/or get jaxnetd RPC credentials.
2. Fill the jaxwallet.conf configuration file. Here is example:

[Application Options]

; Set 1 to use testnet otherwise mainnet will be enabled.
testnet = 0

; uncomment and set path to data directory if want to change defualt: $HOME/.jaxwallet
; appdata=./jaxwallet

; uncomment and set, if additional password was configured 
; walletpass=public

; The server and port used for jaxnetd RPC & websocket connections.
rpcconnect = localhost:18333

; File containing root certificates to authenticate a TLS connections with btcd
; cafile=~/.jaxwallet/btcd.cert
; TLS certificate and key file locations
; rpccert=~/.jaxwallet/rpc.cert
; rpckey=~/.jaxwallet/rpc.key
; onetimetlskey=0
noservertls = 1

rpclisten = 127.0.0.1:8337

; This user/password will be used as 
;   user/password for the jaxwallet rpc
;   AND user/password to auth jaxnetd connection.
; If you would like to use different, 
; please setup jaxnetdusername and jaxnetdpassword
username = jax_rpc_user
password = jax_rpc_pass

; jaxnetdusername=
; jaxnetdpassword=

1. Initialize wallet state by running this command:

./jaxwallet -C ./jaxwallet.conf --create

1. Follow the instructions.
2. Run the following command to start jaxwallet:

./jaxwallet -C ./jaxwallet.conf --create

RPC Usage

jaxwallet and jaxnetd provides a JSON-RPC API with some difference. There are a few key differences between jaxnetd and bitcoind, btcd and JSON-RPC as far as how RPCs are serviced:

• Unlike JSON-RPC the jaxnetd has few additional fields:

  1. scope - sets the context of the request; - node methods related to daemon/node, like getVersion, ping, etc; - chain common methods same for the beacon and shard; - beacon methods that works only for beacon chain; - shard methods that works only for shard chains; - wallet methods that works only for jaxwallet RPC instance;

  2. shard_id - sets to which chain this method will be performed. 0 for beacon chain, >=1 for shard chains.

Here is example of getbalance method for Shard Chain #1.

{
  "method": "getbalance",
  "params": [
    "default"
  ],
  "id": 1,
  "scope": "wallet",
  "shard_id": 1
}

Here is list of enabled method:

	// Reference implementation wallet methods (implemented)
	"addmultisigaddress"
	"createmultisig"
	"dumpprivkey"
	"getaccount"
	"getaccountaddress"

	"walletlock"
	"walletpassphrase"
	"walletpassphrasechange"

	// Extensions to the reference client JSON-RPC API
	"createnewaccount"
	"getbestblock"

	// This was an extension but the reference implementation added it as
	// well, but with a different API (no account parameter).  It's listed
	// here because it hasn't been update to use the reference
	// implemenation's API.
	"getunconfirmedbalance"
	"listaddresstransactions"
	"listalltransactions"
	"renameaccount"
	"walletislocked"
