Base is an Ethereum Layer-2 blockchain designed to deliver strong security, high scalability, and a developer-first environment. The Base ecosystem offers an efficient EVM setup that makes it easy for dApps to integrate with Coinbase products and tap into its distribution channels. The Base was incubated and supported by Coinbase, a leading exchange with more than 100M users.
From October 20, users can complete Base Guild tasks, create a card through the First Dollar app, and participate in additional activities. According to the tweet, Base is exploring a native network token, so we decided to prepare a step-by-step guide on how to join the Base airdrop.
To participate in the potential Base airdrop, you need to be on-chain active and conduct activities on the Base ecosystem Dapps, featured on its website.
Conduct regular token swaps on leading Base chain DEXs, including:

Visit Limitless, a prediction market on Base, connect your wallet, and place a few bets to get started. Active participation on the platform may qualify users for future rewards or points on the platform.
Provide liquidity on Lido, Renzo, or any other staking/restaking protocol on the Base network, and receive liquid staking tokens in return. This activity enables you to farm potential Base drop and APR rewards. To start, simply connect your wallet, switch to Base, stake ETH, and start earning staking rewards while keeping liquidity.
Create a Farcaster account and actively explore the Farcaster ecosystem by using different mini-apps (Frames). Interact with them by minting NFTs, claiming badges, voting, and completing in-app actions such as likes, casts, and follows. At the same time, many of these interactions happen on Base, allowing you to farm potential rewards for both Farcaster (which has no its own token yet) and the Base ecosystem simultaneously.
Download the official Base app, add your Twitter and GitHub profiles, mint a Coinbase.id name, and connect your KYC’d Coinbase account if available. Regularly mint NFTs from the Home page of the app (check the “Trending Onchain” section) and stake USDC on the Base network to earn 4.1% APY. Once you have full access to the app, you can potentially earn Creator Rewards every week.
After, visit the Guild and connect your wallet and Twitter account:
Then you need to start completing several tasks here, such as following Base socials, on-chain activity on the Base chain, interacting with ecosystem apps, and more.
Afterward, you can apply to the Baseapp Waitlist by filling in your email via the website: 
Additionally, First Dollar is a new app built on the Base network and backed by one of Base’s founders. You can already sign up and generate your own card. So you can go to the website, register, and create your unique card by connecting your X account and filling in all fields:
