Frequently Asked Questions (FAQs)

A smart contract is a self-executing computer program that automatically enforces the terms of an agreement between parties. It operates without the need for intermediaries and is built on blockchain technology, making it secure and transparent.

Smart contracts must be reviewed to mitigate the risks of errors, vulnerabilities, and other issues that could compromise their security and functionality. By identifying potential risks and opportunities to improve the code, reviews help reduce the risks of costly mistakes, fraud and hacking attempts.

When you submit your code, it is scanned, compiled with the relevant solidity compiler version, and sent through our testing engine. The testing engine uses static code analysis through both the source code and the solidity AST, and a customized Ethereum Virtual Machine (EVM) dynamically simulates various testing scenarios

The solution is primarily used by EY client-serving professionals. It can also be used directly by the clients and any person or enterprise wanting to assess a smart contract (subject to EY’s client acceptance process, as applicable). We also see interest from tech-savvy specialists, developers, auditors, compliance and risk teams

EY teams’ core business is to provide trust and confidence to business ecosystems. We do that in the assurance business but also across our consulting business. We have robust methodologies and standards in place to deliver quality services to help stakeholders gain more trust in the technology they are using

Our research and experience reveal that most smart contract exploits occur through unexpected behavior of the smart contract and manipulation of edge cases. Functionality testing aims to reduce that risk by verifying that a smart contract behaves as expected. The tool aims to test functionality by both reviewing the required syntax and simulating various scenarios that are part of the ERC-20 standard core functionality.
