Deploying a smart contract with Xahau transactions to an Evernode cluster

Using the Evernode developer kit, you can create an everpocket-nodejs-contract supported multi-signing enabled instance cluster in Evernode and deploy your smart contract with Xahau transactions, as you did locally in “HotPocket tutorial - Xahau transactions”.

This will create an Evernode cluster with the given specs.
Then, as it did in hpdevkit, this will also generate a signer list for the provided master account and upload them to each node in the cluster

Deploy smart contract

Note: For the following steps you can choose either mainnet or testnet. The default will be mainnet, If you want to change you need to set the environment variable as follows.

# Windows (command prompt)
set EV_NETWORK=testnet

# Windows (Powershell)
$env:EV_NETWORK=testnet

# Linux (bash)
export EV_NETWORK=testnet

In the Evernode developer kit, a single command does the cluster creation and the deployment. You need to do the following preparations before same as you did in “Acquire an instance”

First, you need to have a tenant Xahau account with EVRs for the tenant. For the Evernode testnet, you can generate an account with 6000 EVRs using the test account generator (Use EV_NETWORK, EV_SERVER env variables to specify custom network or server).

Same as cluster deployment, follow the [1-5] steps in the cluster deployment tutorial

Now you are ready to deploy the smart contract to an Evernode cluster.

Let’s create a 3-node cluster. Run the following command to create the cluster.

evdevkit cluster-create 3 $HOME/contract /usr/bin/node $HOME/hosts.txt -a index.js --signer-count 3

Note:
- 3 Is the cluster size.
- --signer-count 3 option specifies that you are creating 5 signers inside the cluster.
- Replace $HOME/contract with your contract directory path (Path to build a directory of contract binaries).
- Replace $HOME/hosts.txt with your preferred hosts file path (Path to the Preferred Hosts file created in the previous step).
- Replace /usr/bin/node and index.js with your binary path and arguments.

This will create an Evernode cluster in the preferred hosts, And it’ll internally generate signers for your tenant account you have specified as EV_TENANT_SECRET. Then it outputs the instance details.

You can specify more options (Ex: -m specify life moments) to the cluster-create command. Check the supported options using the below command.
```
evdevkit cluster-create --help
```

At this point, you have created an Evernode cluster successfully and you have details of all the instances including public key, IP, ports, etc. Now you can test the uploaded contract by implementing a user client same as you did in the hpdevkit Xahau transaction tutorial. You will need to point your client to one of the resulting cluster nodes.
