# Verify a contract

Contract verification is essential for transparency and trust in the Filecoin ecosystem. It allows users to inspect the source code of deployed contracts and ensures they function as intended.

## Available Verification Tools

The following FEVM-compatible chain explorers offer contract verification capabilities:

* [Blockscout](https://filecoin.blockscout.com/contract-verification) - Multi-chain explorer with advanced verification options
* [Filfox](https://filfox.info/en/contract) - Native Filecoin explorer with comprehensive verification features
* [Starboard](https://fvm.starboard.ventures/explorer/verifier) - FVM-focused verification platform
* [Beryx](https://beryx.zondax.ch/contract_verifier) - Developer-friendly verification interface
* [Sourcify](https://docs.sourcify.dev/docs/how-to-verify/) - Multi-chain contract repository with verification tools

## Verification Methods

There are two primary approaches to verify your smart contracts:

### Programmatic Verification

Automate contract verification directly from your development environment:
