Practical overview
When it fits
Use it as a hands-on study reference when learning about the listed vulnerability patterns or exploring tests and transaction debugging with Truffle.
Who it is for
- Developers learning how Ethereum smart-contract vulnerabilities and fixes are represented in tests.
- Readers who want to run or inspect the examples using Truffle and a local test blockchain.
Documented uses
- Study examples of common smart-contract bug classes and their fixes.
- Run the documented test suite or an individual test with Truffle.
- Follow the documented local-chain workflow to inspect RPC activity and debug a transaction.
Requirements & limits
The public repository lists a GPL-3.0 license.
- The project is a developer test repository, not a scanner or deployed security service.
- The README provides
truffle test, an individual-test command, and a local-chain debugging workflow. - The README explicitly warns that the included contracts are vulnerable and must not be used.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Run the documented test suite
Run the repository's Mocha tests through Truffle to study its vulnerability and fix examples.
Before you start
- A local copy of the repository
- Truffle
Steps
Open the repository in your development environment.
Run
truffle testfrom the project.
Expected outcome
Truffle runs the repository's test suite, which demonstrates security bugs and fixes.
Guide limitations
- The README warns that the included contracts are vulnerable and must not be used.
- This guide describes the README's instructions; it is not a report of an executed test.
Configure a local test blockchain for debugging
Follow the README's setup instructions for running the test suite against a local development blockchain and inspecting transaction activity.
Before you start
- Truffle
- A local test blockchain
- The repository's
truffle.jsconfiguration file
Steps
Edit
truffle.jswith the README's development network configuration, including hostlocalhostand port8545.Run
testrpcandtruffle console, or usetruffle develop, as described in the README.Use the console to inspect RPC activity and identify a transaction hash when a transaction was made.
Use
truffle debugto inspect a selected transaction.
Expected outcome
The README describes a local debugging workflow for observing RPC calls and examining a transaction.
Guide limitations
- The instructions do not establish that every test produces a transaction.
- The example contracts are explicitly marked as vulnerable and must not be used.
