Practical overview
When it fits
Use it when building a token-research workflow that needs simulated ERC-20 trades and contract-analysis signals before interaction or investment.
Who it is for
- Developers building token-research dashboards or pre-trade screening services.
- Teams that want to run ERC-20 transaction simulation and contract analysis from a self-hosted API.
Documented uses
- Compare simulated buy and sell outcomes for an ERC-20 token.
- Review reported taxes, gas fees and liquidity as part of token research.
- Inspect parsed contract functions and flags for proxies or hidden malicious contracts.
- Gather holder and named-address information through the included scraper.
Requirements & limits
The repository is public and licensed under GNU AGPL-3.0. The README documents local deployment and access at localhost:6457.
- The documented deployment uses Yarn scripts to generate ABI types and start the API.
- Analysis includes simulated buy and sell transactions, tax and gas estimates, liquidity, and contract-function analysis.
- The README cautions that results may be inaccurate.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
