Running the Wallet Daemon

Along with running the Platform natively on your own cloud service, you can also build and run the wallet daemon natively too. This requires just a few steps to configure and build the app which can then be run from the same server as the platform or on a completely different server. It would be highly recommended to run the wallet daemon app on a separate server, and ideally one which is is configured to only allow connections to and from your platform server, or at least not generally accessible directly from the internet. Please note that 2GB of ram would be recommended when building the wallet daemon from source locally.

📘

Prerequisite: Rust Version 1.82

To install or update the wallet daemon, ensure that you have Rust version 1.82 installed. If you need to update Rust, you can do so by running the following command:

Shell

rustup update

1. Start by installing or updating cargo:

   Shell

   apt install cargo
   

2. Install or update the openssl dev libs:

   Shell

   apt-get install libssl-dev pkg-config
   

3. Next add the KEY_PASS and PLATFORM_KEY env vars to your environment variable list so they start on login, to do this create a new wallet-daemon.sh file in /etc/profile.d/:

   Shell

   nano /etc/profile.d/wallet-daemon.sh
   

   And then add the variables, choose a strong password for your KEY_PASS and set your platform's auth token in the PLATFORM_KEY, save the file with ctrl-x followed by y:

   export KEY_PASS="MySuperSecurePassword01"
   export PLATFORM_KEY="Your_Platform_Token_Here"
   

4. Once saved you'll need to log off from your server and log back in so they get loaded.

5. Next, create a new folder to hold the Wallet Daemon repo and build:

   Shell

   cd ~/enjin/
   mkdir wallet-daemon
   

6. Pull the wallet-daemon repo from GitHub:

   Shell

   cd ~/enjin/wallet-daemon/
   git clone https://github.com/enjin/wallet-daemon.git .
   

7. Edit the config.json file in nano to set which blockchain node and platform to connect to and also set where it can find the wallet private key, typically ./store, then save with ctrl-x y:

   Shell

   nano config.json
   

   {
     "node": "wss://rpc.matrix.canary.enjin.io:443",
     "relay_node": "wss://rpc.relay.canary.enjin.io:443",
     "api": "https://your-platform-url.com/graphql",
     "master_key": "./store"
   }

   Using Platform on mainnet?

   If you are using the Enjin Platform on mainnet, make sure to use a mainnet RPC (such as wss://rpc.matrix.blockchain.enjin.io)

8. Build the Wallet Daemon app:

   Shell

   cargo build --release
   

9. Remove the demo Wallet key:

   Shell

   rm store/73723235547f46358c6a32dd1ffb28ee537313a674dc3dc882beb3246e03aa4dc246022f
   

10. Attach to your tmux workers session and create a new pane for the wallet daemon, use ctrl-b " to create a new pane and ctrl-b up-arrow or down-arrow to navigate to it if not already selected:

    Shell

    tmux a -t workers
    

11. Navigate to the wallet-daemon folder in your new pane and then run the wallet build:

    Shell

    cd ~/enjin/wallet-daemon
    ./target/release/wallet-daemon
    

12. Note down the account addresses that will be displayed, these are for your new Wallet Daemon account and will be used to sign transactions.

From here on you simply need to update the DAEMON_ACCOUNT variable in your .ENV with the new wallet account address and fund the account. The wallet daemon will then poll for transactions every 6 seconds and process anything new that you create.

Updating the Wallet Daemon

📘

Prerequisite: Rust Version 1.82

To update the wallet daemon, ensure that you have Rust version 1.82 installed. If you need to update Rust, you can do so by running the following command:

Shell

rustup update

If you're using Supervisor to keep the wallet running (Keeping the Platform Running) , stop it using:

sudo supervisorctl stop platform-wallet:*

Login as your platform user (or from root use su - platform and change to the wallet daemon directory:

cd ~/enjin/wallet-daemon/

Pull the latest version from git and build:

git pull
cargo build --release

To test, you can run directly (omit if using supervisor):

./target/release/wallet-daemon

Start the wallet using supervisor:

sudo supervisorctl start platform-wallet:*

Importing an Existing Wallet Account

If you already have a wallet account that you'd like to use with the wallet daemon then you can import it when you first run the daemon app after building. First make sure the ./store folder is empty and then start the wallet daemon with the import arg:

./target/release/wallet-daemon import

You'll then be asked to type in your 12-word mnemonic phrase. If you had previously generated your account using a password then you will need to add the password to the end of your phrase when importing it like this:

your twelve word phrase///your_password

If you did not set a password then you can omit the forward slashes altogether. After you have entered your phrase (and password if needed) the wallet daemon will create the necessary seed file in the ./store folder ready to use. If a password was used then make sure the same one is set in your KEY_PASS environment variable as documented above. You can now run the wallet daemon as normal and it will use your existing account.
