  1. Smart Contract Audit Guidelines Cyphershield.tech

  2. How to audit a smart contract • To teach you how to audit, I'll audit a contract I wrote myself. This way, you can see a real-world audit that can be done on your own. • Note that an audit is not a legal document that verifies the security of your code. No one can be 100% sure that the code will not be buggy or buggy in the future. • This is just to ensure that your code has been edited by experts and is basically safe. • Discuss possible improvements, primarily to identify risks and vulnerabilities that could compromise a user's ether.

  3. Ok, now let's take a look at the structure of a smart contract audit report: Disclaimer: Here you will say that an audit is not a legally binding document, it does not guarantee anything. This is just a discussion document. Audit overview and good features: Quickly view smart contracts that will be audited and find good practices. Attacks on contracts: In this section, you will discuss attacks on contracts and the consequences. This is just to verify that it is actually safe. Critical vulnerabilities found in contracts: Critical issues that could seriously compromise the integrity of the contract. Those are serious problems that would allow attackers to steal ether.

  4. Moderate vulnerabilities found in contracts: Those that could harm the contract but have limited harm. Like a bug that allows people to modify random variables. Low-severity vulnerabilities: These issues do not actually harm the contract and may already exist in the deployed version of the contract. Line-by-Line Commentary: In this section, you will analyze the most important lines of statements with potential improvements. Audit Summary: Your opinion on the contract and the final conclusion about the audit. Keeping this struct description in a safe place is all you need to do to securely audit a smart contract. It will really help you find those hard-to-find bugs.

  5. Overview • All function and state variable comments are in the standard specification format (ie Ethereum Nature Specification Format, abbreviated as natspec, which is the official code comment format description of the Ethereum community, • The project implements the Oraclize API using a centralized service to generate truly random numbers on the blockchain. • Generating random numbers on a blockchain is a rather difficult subject because one of Ethereum's core values ​​is predictability, and the goal is to ensure that there are no undefined values.

  6. Excellent features This contract provides a nice set of functional code: • Use Oraclize to generate secure random numbers and validate in callbacks. • Modifiers check for end game conditions, blocking key functions until rewards are distributed. • More checks are made to verify that the use of the betting function is appropriate. • The winning number is safely generated only when the maximum number of bets is reached. https://www.cyphershield.tech/#
