Fix Hardhat Sourcify Verification Errors

You will learn how to verify contracts with Sourcify, the decentralized alternative to Etherscan.

The Problem

The hardhat verify sourcify pattern is frequently misapplied in smart contract and dapp development, leading to vulnerabilities, gas inefficiencies, or logic errors. This guide shows the correct implementation and common pitfalls to avoid.

Quick Fix

Wrong

// Only set up Etherscan verification

Contract unverified on Sourcify. Users on decentralized explorers can't see the source.

Right

// hardhat.config.js: sourcify: { enabled: true }. Run: npx hardhat verify --network sepolia <address>

Contract verified on Sourcify's decentralized storage. Source code available on any Sourcify-compatible explorer.

Prevention

• Enable Sourcify alongside Etherscan verification
• Verify metadata matches contract compilation output
• Use DodaTech's multi-explorer verification tool
• Test verification on Sourcify's staging environment
• Monitor Sourcify's supported networks list
