# Smart Contract Deployment

You need to deploy your smart contract for it to be available to users of an U2U network.

To deploy a smart contract, you merely send a transaction containing the compiled code of the smart contract without specifying any recipient.

#### What you'll need <a href="#what-youll-need" id="what-youll-need"></a>

* your contract's bytecode – this is generated through compilation
* U2U for gas – you'll set your gas limit like other transactions so be aware that contract deployment needs a lot more gas than a simple U2U transfer
* a deployment script or plugin
* access to an U2U node, either by running your own, connecting to a public node.

The specific steps involved will depend on the tooling you use. For an example, Remix and [Hardhat](https://hardhat.org/guides/deploying.html). They are the most popular tools for smart contract deployment, which involve writing a script to handle the deployment steps.

Once deployed, your contract will have an address like other accounts.
