# Add contract to project

`POST /v1/account/{accountSlug}/project/{projectSlug}/address`

Add a smart contract to a Tenderly project.

**Note**: If a contract is unverified on both Tenderly and external providers like Etherscan, Blockscout, or Routescan, it will be added to the project as **unverified**. However, if the contract is verified on an external provider, Tenderly will retrieve and apply the verification, subsequently adding the verified contract to the project.
