# Get started with Casper

### Task 1: Create and deploy a simple smart contract

-- Installed Rust Programming language as well as Cmake

-- Created a new project named my-project

-- Installed the Rust toolchain and set the target build as wasm32-unknown-unknown (WebAssembly)

-- Finally build the contract using 'cargo build --release'

-- Tested the contract using 'make test'


NOTE: I faced a lot of issues while using Windows as well as WSL. Finally switched to Linux and all worked well.

### Task 2: One of the existing Tutorial

Implemented the Multi-Signature Tutorial

-- Cloned the repository using 'git clone https://github.com/casper-ecosystem/keys-manager'

-- Compiled the smart contract and created the WASM file (keys-manager.wasm)

-- Set up the local Casper Network using nctl- It created a faucet account which holds the tokens.

-- Created a .env file inside the client folder and added the 'BASE_KEY_PATH', 'NODE_URL' variables inside it. Ran npm install to install the required JavaScript packages.

-- Tested the client using 'npm run start:atomic' which ran successfully.


NOTE: I got an error 'Cannot open an HTTP server: socket.error reported AF_UNIX path too long' which was resolved by reducing the directory length while running nctl in the casper-node directory

### Task 3: Modifying client in Multi-Sig tutorial to address one of the additional scenarios

Implemeted Scenario 1 where we had to sign transactions with a single key.

-- Edited the scenario-atomic.js

-- Set the MainAccount weight, Keys Management Threshold and Deploy Threshold to 1

-- Ran 'npm run start:atomic'



### Task 4: Transfer tokens to an account on the Casper Testnet

Did a direct transfer

-- Generated keys using a block explorer (Casper Testnet) and save the keys

-- Fuded the account faucet

-- Transferred 2.5 Cspr

### Task 5: Delegate and Undelegate on the Casper Testnet

Delegate : https://testnet.cspr.live/deploy/4d5c9f8f49ee98ac70bcce4e23ea500f3ebcfbb0a9cfbea3add65b36c28eb608


Undelegate : https://testnet.cspr.live/deploy/d7c9dc2e04ef9aa18130e7b3efd795ee9ce7449d005b2a625b7db468fc4acd15


It was fun getting to know about the Casper ecosystem.
