Solidity Test

NFT deployed to: 0xC09Ff9115C1CE86a3F1Bd501a625772fd299cd42 PwnNFT contract deployed to:

To use:

Hit the deposit function of the NFT contract with one wallet. You can then use the frontend to steal those funds from another wallet by exploiting via re-entrancy

Easiest way to trigger a deposit on the original contract is by uploading the ABI to https://eth95.dev/

You have to be on the AVAX Fuji network, though this works on any EVM chain. Further improvements include suggesting a chain switch to metamask if the wrong chain is detected.

Pre Requisites

Before running any command, you need to create a .env file and set a BIP-39 compatible mnemonic as an environment variable. Follow the example in .env.example. If you don't already have a mnemonic, use this website to generate one.

Then, proceed with installing dependencies:

$ yarn install

Compile

Compile the smart contracts with Hardhat:

$ yarn compile

TypeChain

Compile the smart contracts and generate TypeChain artifacts:

$ yarn typechain

Lint Solidity

Lint the Solidity code:

$ yarn lint:sol

Lint TypeScript

Lint the TypeScript code:

$ yarn lint:ts

Test

Run the Mocha tests:

$ yarn test

Coverage

Generate the code coverage report:

$ yarn coverage

Report Gas

See the gas usage per unit test and average gas per method call:

$ REPORT_GAS=true yarn test

Clean

Delete the smart contract artifacts, the coverage reports and the Hardhat cache:

$ yarn clean

Deploy

Deploy the contracts to Hardhat Network:

$ yarn deploy --greeting "Bonjour, le monde!"

Syntax Highlighting

If you use VSCode, you can enjoy syntax highlighting for your Solidity code via the hardhat-vscode extension.

Caveats

Ethers and Waffle

If you can't get the Waffle matchers to work, try to make your ethers package version match the version used by the @ethereum-waffle/chai package. Seem #111 for more details.
