# Get started with Casper

## 1. Create and deploy a simple, smart contract with cargo casper and cargo test

**Build the Contract**


**Test the Contract**


**Compile the NCTL binary scripts.**


**Set up all the assets required to run a local network, including binaries, chainspec, config, faucet, and keys. Also, spin up the network right after. The default network will have 10 nodes, with 5 active nodes and 5 inactive nodes.**


See the Faucet Account


**Deploying Contracts**

Install the client on most flavors of Linux


Check the Client Version


**Sending a Deployment to the Testnet**


**Check Deploy Status**


## 2. Complete one of the existing tutorials for writing smart contracts

**A Counter Contract Tutorial**

View the Network State

Faucet information


Get the state root hash


Query the actual state


**Deploy the Counter**

Builds the contracts and verifies


Call the casper-client put-deploy command to put the contract on the chain.


Verify that the deploy successfully took place.


**View the Updated Network State**

Get the NEW state-root-hash:


Get the network state:


**Increment the Counter**


**View the Updated Network State Again**

Get the NEW state-root-hash:


Get the network state, specifically for the count variable this time:


**Increment the Counter Again**


**View the Final Network State**

Get the NEW state-root-hash:


Get the network state, specifically for the count variable this time:


## 3. Demonstrate key management concepts by modifying the client in the Multi-Sig tutorial to address one of the additional scenarios

**Building the Smart Contract**

Compile the smart contract and create the WASM file


Setting up the Client


**Testing the Client**


**Additional Scenarios**

**Scenario 3: signing transactions with multiple keys**

Modify file package.json with following:

Final Result:


## 4. Learn to transfer tokens to an account on the Casper Testnet.


## 5. Learn to Delegate and Undelegate on the Casper Testnet.

**Delegate to a Validator**


**Undelegate to a Validator**
