In the crypto market, there is a potential recovery underway as Bitcoin (BTC) approaches the $90,000 mark. Startups are taking advantage of this positive sentiment by launching appealing airdrops, giving crypto enthusiasts a chance to engage with emerging platforms without needing to invest initially.

Three projects, backed by notable investors, are offering opportunities for airdrop participation this week.

Optimism, a Layer-2 blockchain network, is among the top airdrops. The project recently secured $267.50 million in funding from investors like Andreessen Horowitz, Coinbase Ventures, Paradigm, and IDEO CoLab Ventures. Their SuperStacks Campaign, running until June 30, rewards participants with points for interacting with the project and providing liquidity to superchains aimed at solving Ethereum fragmentation.

Aztec, a privacy-focused Layer-2 zero-knowledge (ZK) rollup on Ethereum, is another project offering a promising airdrop. With $119.1 million in funding from investors like Andreessen Horowitz, Paradigm, Consensys, and Coinbase Ventures, Aztec announced an upcoming AZTEC token and a confirmed retroactive airdrop for early users.

Huma Finance, a PayFi network built on Solana, introduces a point farming program on its network. Users can deposit USDC tokens to earn Feathers without needing KYC verification. Huma Finance also launched social and deposit quests on Galxe, offering participants a chance to win a share of $2,000 without KYC requirements.

Overall, these projects are leveraging airdrops to attract users, with Optimism, Aztec, and Huma Finance paving the way for crypto enthusiasts to engage with innovative blockchain networks and potentially earn rewards.
