Simple lottery caninster built on the ICP network.

• It allows any player to be able to start the lottery, buy tickets and even end the lottery.
• Players can then check to see if they're the lucky winners of that lottery.
• Winner gets half of the prizepool.

• Start the Local Internet Computer

  dfx start --background --clean

• Deploy the Ledger Canister

  npm run deploy:ledger

• Deploy the Internet Identity Canister

  dfx deploy internet_identity

• Deploy the Lottery Backend Canister

  # ticket price is entered in e8s
  # lottery duration is entered in minutes for testing purposes
  
  dfx deploy dfinity_js_backend --argument '(record {ticketPrice = 100000000; lotteryDuration = 10})'

• Deploy the Frontend Canister

  dfx deploy dfinity_js_frontend

This next step shows how to fund your wallet with the tokens from the newly deployed Ledger canister.

• Copy your wallet ledger identifier from the frontend of lottery. This can be found in the wallet icon.

• Run the faucet script

  # npm run get:tokens <amount in e8s> <amount> <wallet address>
  npm run get:tokens 5_0000_0000 123525952y5y2835y235788238527358235823857
  
  # N/B: This sends 5 ICP tokens to the address.
