3. Solaxy ($SOLX)

The Solaxy (SOLX) presale is rapidly gaining attention as one of the largest crypto fundraising events in 2025, surpassing $25 million. Although daily contributions have slightly slowed, investor interest remains strong. With the next milestone of $25.6 million approaching, Solaxy is proving to be a promising Layer-2 solution for the Solana blockchain.

Solaxy’s success stems from its ability to address Solana’s congestion issues. Network congestion has become a concern as Solana dominates the DeFi and meme coin markets. Solaxy’s Layer-2 scaling solution processes transactions off-chain before settling them on Solana’s mainnet, reducing strain and improving efficiency. Additionally, Hyperlane’s repository integration will allow seamless asset transfers across Solana, Ethereum, Base, and Solaxy, enhancing interoperability.

Early investors can stake $SOLX at an impressive 162% yield, with over 7.1 billion tokens already locked. As more tokens are staked, the yield gradually decreases, rewarding early participants. A Coinsult audit confirmed that no additional tokens can be minted, increasing investor confidence.

With its Token Generation Event (TGE) and upcoming decentralized exchange (DEX) listing, excitement is growing. Analysts predict that Solaxy could potentially 50x when Solana surges, making it a compelling Layer-2 investment opportunity.
