# Solidity-Reentrancy-Attack-Example
## OVERVIEW
This repo shows a reentrancy attack in action, as well as a fix to mitigate the attack. With tests to show the process of how it all works.
## GET STARTED
This project uses a [task runner called just, for convenience](https://github.com/casey/just)
```
Available recipes:
default
install *PACKAGES
update
compile
compile-watch
deploy-localhost
deploy-testnet
verify-testnet
test
test-watch
lint
start
format
audit
print-audit
print-gas-usage
print-deployments
clean
```
### Running tests and audits
- Run the unit tests with `just test`
- Statically analyse code for vulnerabilities with `just audit`
### Starting a new project from this template
- Clean the workspace (to start a new project, removing example code and scripts) using `just clean`
- Create your solidity code in `/contracts`, tests in `/test` and deploy/verify scripts in `/scripts`
## Available Tasks
See `./tasks/index.ts` to view available tasks and enable them.
Some might require a little configuration
## FAQ
### Error compiling contracts on freshly cloned repo
`Error HH12: Trying to use a non-local installation of Hardhat, which is not supported.
Please install Hardhat locally using npm or Yarn, and try again.`
Run `npm i` to fix this error which will install hardhat
### Performance optimizations
For faster runs of your tests and scripts, consider skipping ts-node's type checking by setting the environment variable TS_NODE_TRANSPILE_ONLY to 1 in hardhat's environment. For more details see the documentation.
### Husky
ERROR ON COMMIT -> `husky > pre-commit hook failed (add --no-verify to bypass)`
RESOLUTION -> Remove errors from your smart contracts, found running `npm run lint`, or commit using --no-amend flag to temporarily bypass.
### Error running audit task
Ensure [Slither](https://github.com/crytic/slither) is installed and in your $PATH
