# Foundry - Deploying Contracts

> Learn how to deploy smart contracts on Abstract using Foundry.

## Deploying Contracts

<Steps>
  <Step title="Add your deployer wallet's private key">
    Create a new [wallet keystore](https://book.getfoundry.sh/reference/cast/cast-wallet-import) to securely store your deployer account's private key.

    ```bash theme={null}
    cast wallet import myKeystore --interactive
    ```

    Enter your wallet's private key when prompted and provide a password to encrypt it.
  </Step>

  <Step title="Get ETH in the deployer account">
    The deployer account requires ETH to deploy a smart contract.

    * **Testnet**: Claim ETH via a [faucet](/tooling/faucets), or
      [bridge](/tooling/bridges) ETH from Sepolia.
    * **Mainnet**: Use a [bridge](/tooling/bridges) to transfer ETH to Abstract mainnet.
  </Step>

  <Step title="Deploy your smart contract">
    Run the following command to deploy your smart contracts:

    <CodeGroup>
      ```bash Testnet theme={null}
      forge create src/Counter.sol:Counter \
          --account myKeystore \
          --rpc-url https://api.testnet.abs.xyz \
          --chain 11124 \
          --zksync \
          --verify \
          --verifier etherscan \
          --verifier-url https://api-sepolia.abscan.org/api \
          --etherscan-api-key TACK2D1RGYX9U7MC31SZWWQ7FCWRYQ96AD
      ```

      ```bash Mainnet theme={null}
      forge create src/Counter.sol:Counter \
          --account myKeystore \
          --rpc-url https://api.mainnet.abs.xyz \
          --chain 2741 \
          --zksync \
          --verify \
          --verifier etherscan \
          --verifier-url https://api.abscan.org/api \
          --etherscan-api-key <your-abscan-api-key>
      ```
    </CodeGroup>

    ***Note**: Replace the contract path and Etherscan API key with your own.*

    If successful, the output should look similar to the following:

    ```bash {2} theme={null}
    Deployer: 0x9C073184e74Af6D10DF575e724DC4712D98976aC
    Deployed to: 0x85717893A18F255285AB48d7bE245ddcD047dEAE
    Transaction hash: 0x2a4c7c32f26b078d080836b247db3e6c7d0216458a834cfb8362a2ac84e68d9f
    ```
  </Step>
</Steps>

## Providing Constructor Arguments

If your smart contract has a constructor with arguments, provide the arguments in the order they are defined in the constructor following the `--constructor-args` flag.

<CodeGroup>
  ```bash Testnet theme={null}
  forge create src/Counter.sol:Counter \
      --account myKeystore \
      --rpc-url https://api.testnet.abs.xyz \
      --chain 11124 \
      --zksync \
      --constructor-args 1000000000000000000 0x9C073184e74Af6D10DF575e724DC4712D98976aC \
      --verify \
      --verifier etherscan \
      --verifier-url https://api-sepolia.abscan.org/api \
      --etherscan-api-key TACK2D1RGYX9U7MC31SZWWQ7FCWRYQ96AD
  ```

  ```bash Mainnet theme={null}
  forge create src/Counter.sol:Counter \
      --account myKeystore \
      --rpc-url https://api.mainnet.abs.xyz \
      --chain 2741 \
      --zksync \
      --constructor-args 1000000000000000000 0x9C073184e74Af6D10DF575e724DC4712D98976aC \
      --verify \
      --verifier etherscan \
      --verifier-url https://api.abscan.org/api \
      --etherscan-api-key <your-abscan-api-key>
  ```
</CodeGroup>

***Note**: Replace the contract path, constructor arguments, and Abscan API key with your own.*
