**Prerequisites**

Install the Rust programming language


**Installing Dependencies**

CMake


**Development Environment Setup**

Compiling the contract to WASM


Test the Contract


**Setting up the Network**

Compile the NCTL binary scripts.


Set up the assets required to run a local network


**Deploying Contracts**

Check the Client Version


**Sending a Deployment to the Testnet**


**Check Deploy Status**


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

### Multi-Signature Tutorial is choosed for installation

**Building the Smart Contract**


**Setting up the Client**

File .env look like


Install the JavaScript packages in the keys-manager/client folder


**Testing the Client**


## Demonstrate key management concepts

### Scenario 1: signing transactions with a single key is choosed for installation

(async function () {

  let deploy;

  // 0. Initial state of the account.
  // There should be only one associated key (fuacet) with weight 1.
  // Deployment Threshold should be set to 1.
  // Key Management Threshold should be set to 1.
  let masterKey = keyManager.randomMasterKey();
  let mainAccount = masterKey.deriveIndex(1);

  console.log("\n0.1 Fund main account.\n");
  await keyManager.fundAccount(mainAccount);
  await keyManager.printAccount(mainAccount);

  console.log("\n[x]0.2 Install Keys Manager contract");
  deploy = keyManager.keys.buildContractInstallDeploy(mainAccount);
  await keyManager.sendDeploy(deploy, [mainAccount]);
  await keyManager.printAccount(mainAccount);

  // 1. Set mainAccount's weight to 1
  console.log("\n1. Set faucet's weight to 1\n");
  deploy = keyManager.keys.setKeyWeightDeploy(mainAccount, mainAccount, 1);
  await keyManager.sendDeploy(deploy, [mainAccount]);
  await keyManager.printAccount(mainAccount);

  // 2. Set Keys Management Threshold to 1.
  console.log("\n2. Set Keys Management Threshold to 1\n");
  deploy = keyManager.keys.setKeyManagementThresholdDeploy(mainAccount, 1);
  await keyManager.sendDeploy(deploy, [mainAccount]);
  await keyManager.printAccount(mainAccount);

  // 3. Set Deploy Threshold to 1.
  console.log("\n3. Set Deploy Threshold to 1.\n");
  deploy = keyManager.keys.setDeploymentThresholdDeploy(mainAccount, 1);
  await keyManager.sendDeploy(deploy, [mainAccount]);
  await keyManager.printAccount(mainAccount);
})();
