Test quiz from gamerse

Requirements.

1. create a erc 20 compliment contract that uses an oracle to connect to https://www.wolframalpha.com
2. use roll a dice function
3. if the result is more than 5 It will mint and issue 10 tokens to an address.
4. use truffle to connect to the contract and display the list of dice results and update the new balance of the address on screen.
5. display the transaction ID a d link to it on the test net

The Answers

Compile the contract

truffle compile

Test the contract in local

Start the local nodes by

ganache-cli

Run the test

truffle test

Deploy the contract on BSC testnet

Before deploy, need to put the meta mask wallet seeds into .secrets file, so the truffle wallet can use it to interact with BSC testnet.

truffle migrate --network testnet

The deployment result on BSC testnet.

Test the contract on testnet and with oracle

First need to export your walfram API key(which is the appid) as the environment variable.

export API_KEY="xxxxxxxxxx"

and run scripts

truffle exec --network testnet scripts/test_gamerse_with_testnet.js

it will show the dice result and balances before and after roll the dice.

An transaction example.
