# Reown (Previously WalletConnect) Project ID For Contract Read/Write

<Info>
  The latest versions of Blockscout use Reown (previously WalletConnect) for Read and Write functionality with smart contracts. The frontend variable `NEXT_PUBLIC_WALLET_CONNECT_PROJECT_ID` must be enabled with your project ID for this feature to work.

## Setting up a Reown Project ID

1\) Go to [https://cloud.reown.com/sign-in](https://cloud.reown.com/sign-in) and sign in or create an account.

2\) Create a new Project

6\) Scroll down to see your basic information, including your Project ID. Before using, however, **setup Project Domains**. Please include any urls which host your explorer(s) here.

<Warning>
  This step is important because the Project ID will be exposed in the browser. Setting allowed domains prevents unauthorized usage of your ID.
</Warning>

You can also verify your domain domains. This is not required but is recommended for security. Instructions are included in the interface.

<Tip>
  You Blockscout instance will now support the Reown Project ID for Contract Read and Write functionality. [-> See more front-end ENVs related to Blockchain and contract interaction](https://github.com/blockscout/frontend/blob/main/docs/ENVS.md#blockchain-interaction-writing-to-contract-etc).
