Create ERC20 Crowdsale Contract on Optimism

To create a crowdsale on the Optimism network, you'll first need to have an ERC20 token that you want to offer for sale. If you don't have an ERC20 token yet, you can easily create a token on Optimism using Token Tool. Once you have the token, you can proceed to create the token sale smart contract, specify the token contract address or select the token from the drop-down menu once you connect with your wallet.

After configuring the necessary parameters through the launchpad based on your token presale terms, click “Create Sale” and pay the Token Tool fees and network fees by confirming the transaction in your wallet. The smart contract will then be deployed on the Optimism network. Once deployed, your token sale will be ready, and you can start accepting investments from interested investors.

Accepting payments and distributing tokens for your token sale is a straightforward process. During the creation of your token sale, you'll select a payment token through which you wish to receive investments. Once the token presale is successfully created, you need to send the tokens to the token presale contract address using the "Manage Token Sale" function.

You will receive a "Token Sale Display Link," which serves as an interface for investors to submit investments. This link can be embedded in an HTML iFrame on your website or shared directly with investors. Investors will connect their wallets, enter the amount they wish to invest, confirm the transaction, and pay directly from their wallets. After the token presale is completed, investors should return to the same page to claim their tokens. As the issuer, you can withdraw funds from the token sale contract using the "Manage Token Sale" function.
