 [Sourcify](https://sourcify.dev/#/verifier) is another tool for verifying contracts that is open-sourced and decentralized. It is not a block explorer and only verifies contracts on [different EVM based networks](https://docs.sourcify.dev/docs/chains). It acts as a public infrastructure for other tools to build on top of it, and aims to enable more human-friendly contract interactions using the [ABI](/developers/docs/smart-contracts/compiling/#web-applications) and [NatSpec](https://docs.soliditylang.org/en/v0.8.15/natspec-format.html) comments found in the metadata file.
 
-Unlike Etherscan, Sourcify supports full matches with the metadata hash. The verified contracts are served in its [public repository](https://docs.sourcify.dev/docs/repository/) on HTTP and [IPFS](https://docs.ipfs.io/concepts/what-is-ipfs/#what-is-ipfs), which is a decentralized, [content-addressed](https://web3.storage/docs/concepts/content-addressing/) storage. This allows fetching the metadata file of a contract over IPFS since the appended metadata hash is an IPFS hash.

 Additionally, one can also retrieve the source code files over IPFS, as IPFS hashes of these files are also found in the metadata. A contract can be verified by providing the metadata file and source files over its API or the [UI](https://sourcify.dev/#/verifier), or using the plugins. Sourcify monitoring tool also listens to contract creations on new blocks and tries to verify the contracts if their metadata and source files are published on IPFS.

 ### Tenderly {#tenderly}
 
 The [Tenderly platform](https://tenderly.co/) enables Web3 developers to build, test, monitor, and operate smart contracts. Combining debugging tools with observability and infrastructure building blocks, Tenderly helps developers accelerate smart contract development. To fully enable Tenderly features, developers need to [perform source code verification](https://docs.tenderly.co/monitoring/contract-verification) using several methods.
 
 It's possible to verify a contract privately or publicly. If verified privately, the smart contract is visible only to you (and other members in your project). Verifying a contract publicly makes it visible to everyone using the Tenderly platform.
 
-You can verify your contracts using the [Dashboard](https://docs.tenderly.co/monitoring/smart-contract-verification/verifying-a-smart-contract), [Tenderly Hardhat plugin](https://docs.tenderly.co/monitoring/smart-contract-verification/verifying-contracts-using-the-tenderly-hardhat-plugin), or [CLI](https://docs.tenderly.co/monitoring/smart-contract-verification/verifying-contracts-using-cli).

 When verifying contracts through the Dashboard, you need to import the source file or the metadata file generated by the Solidity compiler, the address/network, and compiler settings.
