FAQPage Schema

How do I verify Solidity contracts on Avalanche explorers?▼

Verify Solidity contracts on Avalanche explorers by recompiling source code and matching bytecode against deployed addresses to confirm authenticity. This process supports diverse developer workflows and detailed source management.

Can I use Hardhat or Foundry for contract verification on Snowtrace?▼

Yes, Snowtrace contract verification supports multiple methods including the Hardhat plugin, Foundry, Sourcify, and manual UI verification. This flexibility lets developers choose their preferred framework for source code authentication.

What is automated source matching for Solidity verification?▼

Automated source matching recompiles Solidity code and compares the generated bytecode against deployed contract bytecode. This confirms source code authenticity without manual checks, enhancing developer confidence.

Does Sourcify work with Avalanche Fuji contract verification?▼

Yes, Sourcify is supported for verifying contracts deployed on Avalanche Fuji. Verifying source code on Snowtrace enables public auditing and interaction with deployed smart contracts.

Why does bytecode matching fail during Snowtrace verification?▼

Bytecode matching during Snowtrace verification fails when compiler settings or source files do not exactly match the original deployment configuration. Ensuring accurate compiler inputs and complete source files resolves these discrepancies.
