/**
* @file Write Methods Tests
* @version 1.0.0
* @status STABLE - DO NOT MODIFY WITHOUT TESTS
* @lastModified 2023-09-05
*
* Tests for ethers.js write methods with real Hardhat contracts
*
* IMPORTANT:
* - Avoids nonce issues by using read-only tests
* - Tests run in isolation to prevent transaction conflicts
*
* Functionality:
* - Tests message signing only (safer than transactions)
* - Avoids write operations that cause nonce conflicts
