Casper Hackathon

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

Build the Contract

The step to compile the smart contract into WASM. Inside the contract folder, run the following command:

cd contract
cargo build --release

Test the Contract

In addition to creating the contract, the Casper crate also automatically created sample tests in the my-project/tests folder.

cd ..
make test


Writing Smart Contract with AssemblyScipt

Compile to WASM - To compile the contract to WASM, use npm to run the asbuild script from the project root:

`npm run asbuild`


Local Network Testing

Installing a Virtual Environment

Run the following commands to set it up

`source env/bin/activate`

Activate the NCTL environment with the following command.

`source casper-node/utils/nctl/activate`

Compile the NCTL binary scripts.

`nctl-compile`

Spin up the network

`nctl-assets-setup && nctl-start`


The Casper Client

Run the commands below to install the client

rustup toolchain install nightly
cargo +nightly-2021-06-17 install casper-client --locked


Sending a Deployment to the Testnet


Check to see that the contract executed properly, and that the block was finalized.


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

## Multi-Signature Tutorial

Compile the smart contract and create the WASM file using these commands:

cd contract
cargo build --release

Navigate to your casper-node folder and run the following NCTL commands.

nctl-compile
nctl-assets-setup && nctl-start


See your faucet account details with the command below.

`nctl-view-faucet-account`


Testing the Client

Navigate to your /keys-manager/client folder and run the keys-manager using npm. Your WASM file’s path is relative to the client folder, so you need to run the file from here.

`npm run start:atomic`

(env) root@virtual-machine-57383-vps-eu:~/keys-manager/client# npm run start:atomic

> keys-manager@1.0.0 start:atomic
> node -r dotenv/config ./src/scenario-atomic.js

> Additional Scenarios

# Submission 3: Demonstrate key management concepts

## Scenario 1: signing transactions with a single key

> Step 1: Make a new code to demo the scenario 1 and ~/keys-manager/client/src

The code is below:

(env) root@virtual-machine-57383-vps-eu:~/keys-manager/client# cat src/scenario_1.js
const keyManager = require("./key-manager");
const TRANSFER_AMOUNT = process.env.TRANSFER_AMOUNT || 2500000000;

(async function () {
  let deploy;
  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);
})();

> Step 2: Add the scenario 1 location to package.json

Run the command below to demo the srcipt:

`npm run start:scenario_1`

root@virtual-machine-57383-vps-eu:~/keys-manager/client# npm run start:scenario_1

> keys-manager@1.0.0 start:scenario_1
> node -r dotenv/config ./src/scenario_1.js
