dcrwallet is a daemon handling decred wallet functionality for a single user. It acts as both an RPC client to dcrd and an RPC server for wallet clients and legacy RPC applications.

Public and private keys are derived using the heirarchical deterministic format described by BIP0032. Unencrypted private keys are not supported and are never written to disk. dcrwallet 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, dcrwallet 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.

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

Mainnet support is currently disabled by default. Use of dcrwallet on mainnet requires passing the --mainnet flag on the command line or adding mainnet=1 to the configuration file. Mainnet will be enabled by default in a future release after further database changes and testing.

• Install Go according to the installation instructions here: http://golang.org/doc/install

• Run the following commands to obtain and install dcrwallet and all dependencies:

$ go get -u -v github.com/decred/dcrd/...
$ go get -u -v github.com/decred/dcrwallet/...

• dcrd and dcrwallet will now be installed in either $GOROOT/bin or $GOPATH/bin depending on your configuration. If you did not already add to your system path during the installation, we recommend you do so now.

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

$ go get -u -v github.com/decred/dcrd/...
$ go get -u -v github.com/decred/dcrwallet/...

The follow instructions detail how to get started with dcrwallet connecting to a localhost dcrd.

• Run the following command to start dcrd:

$ dcrd --testnet -u rpcuser -P rpcpass

• Run the following command to create a wallet:

$ dcrwallet -u rpcuser -P rpcpass --create

• Run the following command to start dcrwallet:

$ dcrwallet -u rpcuser -P rpcpass

If everything appears to be working, it is recommended at this point to copy the sample dcrd and dcrwallet configurations and update with your RPC username and password.

$ cp $GOPATH/src/github.com/decred/dcrd/sample-dcrd.conf ~/.dcrd/dcrd.conf
$ cp $GOPATH/src/github.com/decred/dcrwallet/sample-dcrwallet.conf ~/.dcrwallet/dcrwallet.conf
$ $EDITOR ~/.dcrd/dcrd.conf
$ $EDITOR ~/.dcrwallet/dcrwallet.conf

Clients wishing to use dcrwallet are recommended to connect to the ws endpoint over a websocket connection. Websocket connections also enable additional API extensions and JSON-RPC notifications (currently undocumented). The dcrd packages dcrjson and dcrws provide types and functions for creating and JSON (un)marshaling these requests and notifications.
