- Hedera Mainnet (chain ID 295) and Testnet (chain ID 296) are now natively supported on the main sourcify.dev verification platform.
- Developers can verify Hedera smart contracts using standard EVM tooling like Hardhat, Foundry, and Remix without any custom plugins or configuration.
- Verified contracts are accessible across the broader EVM ecosystem, including in shared databases like the Verifier Alliance, and will show as verified on HashScan.
Hedera has achieved a significant integration milestone for its developer community by adding native support for its networks to the decentralized smart contract verification service Sourcify. This integration, announced on the Hedera blog, means developers building on the Hedera Mainnet and Testnet can now verify their contract source code using the same industry-standard, open-source tooling employed across many other EVM chains. Consequently, workflows involving popular frameworks like Hardhat, Foundry, and the Remix IDE will function seamlessly on Hedera without requiring custom setups.
The primary service enabling this, sourcify.dev, is a decentralized verification platform that cryptographically confirms a deployed contract’s bytecode matches its purported source code. According to the announcement, this process supports two verification levels: an “Exact Match” for byte-for-byte correspondence and a “Partial Match” for functionally identical code. Meanwhile, this integration grants Hedera contracts visibility within a wider verification ecosystem, as tools and explorers that read from Sourcify’s repository can now display Hedera contract source code.
For developers, the practical impact is straightforward verification using familiar commands. They can use npx hardhat verify --network hedera_testnet or forge verify-contract with the --verifier sourcify flag, as outlined in the provided tutorials. Furthermore, contracts verified on the main Sourcify instance become part of cross-chain datasets like the Verifier Alliance, which already contains over 100,000 entries. Manual verification for contracts is also available, where the process on HashScan will redirect users to the main Sourcify instance page to select the appropriate Hedera network.
