Some Best Practices for Ethereum Smart Contracts

Solidity Best Practices for Ethereum Smart Contracts

Solidity is a programming language that is object-oriented and used to write smart contracts. Usually, solidity smart contracts are intended to run on Ethereum Virtual Machine (EVM). It is good to have a deep understanding of Solidity to write effective Ethereum smart contracts.

Let’s discuss some best practices that will help you to ensure that your Ethereum smart contracts written in Solidity are secure.

1. Enforce invariants withassert()

Whenever an assertation fails, an asset guard is triggered. For example, in a token issuance contract, the token to Ether issuance ratio may be fixed. You can ensure that this always happens with the help of assert().

However, note that asserts guards is combined with other techniques like allowing upgrades often so that you don’t end up being stuck with an assertion that is always failing.

2. Properly use assert(), require()

assert(), require() are convenience functions that can be used to look for conditions and throw an exception if the condition isn’t met. While the assert() function is used only to test for internal errors and verify variants, the require() function should validate return values from calls and ensure valid conditions.
