  One of the best practices to prevent the 'cannot read properties of undefined' error in cryptocurrency smart contracts is to perform proper input validation. This means thoroughly checking and validating all input parameters and variables before using them in the contract code. By ensuring that all inputs are properly defined and initialized, you can avoid encountering this error. Additionally, using guard clauses and conditional statements can help prevent the execution of code that relies on undefined properties, reducing the likelihood of encountering this error.
