How App Chains, Stablecoins, and Layer 3 Will Reshape Blockchain in 2025

As blockchain technology continues to advance, Web3 is entering a transformative phase defined by user-centric innovations, scalability breakthroughs, and real-world payment solutions. From app chains enhancing user experiences to Layer 3 innovations tackling scalability challenges, 2025 promises to be a pivotal year for the crypto ecosystem.

BeInCrypto spoke with several key figures in the crypto and Web3 industry to uncover how these innovations will influence the ecosystem in the coming year.

The Next Chapter of Web3: User-Centric Innovations in 2025

The evolution of Web3 is increasingly focused on creating user-centered blockchain applications. App chains, which are application-specific blockchains, are gaining traction as tools to reduce costs and enhance user experience. 

Eowyn Chen, CEO of Trust Wallet, describes app chains as a pivotal development for Web3’s future. She anticipates that more applications with significant traffic and volume will leverage these technologies in 2025 to improve efficiency and scalability.

“2024 was about the proliferation of Layer 2 public chains. In 2025, I expect more applications with volume and traffic to move into chain as an infrastructure to enhance user experience and cost reduction,” Chen explained.

Complementing these advancements, Web3 technologies are increasingly integrating into daily life through super apps. Sam Seo, Chairman of Kaia DLT Foundation, highlights platforms like LINE, which are already experimenting with mini-Dapps designed to bridge blockchain technology and mainstream adoption.

“Platforms like LINE are already exploring mini-Dapps, which will set the tone for mainstream Web3 adoption,” Seo shared.

Additionally, Dr. Lin Han, founder and CEO of Gate.io, underscores the critical role of decentralized identity and scalable Layer-2 (L2) solutions in creating seamless user experiences. He believes these technologies will drive inclusivity and accessibility by fostering blockchain interoperability and integration within the digital economy.

From Layer 3 to Payments: Fresh Crypto Trends to Watch in 2025

Besides L2s, the emergence of Layer-3 (L3) solutions also promises to revolutionize scalability and efficiency further. Building on Layer 2 infrastructure, these solutions aim to address persistent challenges such as speed and cost, unlocking new possibilities for mass adoption. Thomas Kralow, Chairman of EVEDEX, foresees a significant surge in Layer 3 adoption, particularly on Ethereum and Bitcoin.

“The strengthening of established cryptocurrencies will parallel the rise of fraudulent projects in 2025. This dual trend highlights the importance of education within the blockchain ecosystem to foster informed and cautious participation,” Kralow emphasized.

Beyond technical advancements, Layer 3 solutions are enabling tailored use cases that address diverse user needs. By offering efficiency and scalability, they serve as a cornerstone for blockchain’s next growth phase.

Furthermore, these experts foresee how stablecoins are going to reshape various industries such as real estate, supply chain management, and global payments. CoinEx Research highlights their integration into traditional markets as a defining trend for 2025, enabling broader financial accessibility and reducing transaction costs.

“Stablecoins are emerging as critical tools for liquidity and stability in DeFi markets. Their integration into real-world applications will redefine financial accessibility,” CoinEx Research noted.

Eowyn Chen echoes this sentiment. She emphasizes stablecoins’ pivotal role in expanding blockchain’s utility. Chen also projects their continued growth supporting liquidity and stability while driving real-world payment adoption.

“Continued growth in the use and variety of stablecoins is critical for liquidity and stability in DeFi markets. I also expect to see more payments made through stablecoins in the real world,” she elaborated.

Meanwhile, Daniel Lynch, Head of Strategy for MetaMask Card & LATAM at Consensys, envisions blockchain technology shifting to address everyday financial needs. He stresses the importance of creating tools that enhance financial inclusion and improve user experiences.

“The largest trends and responsibilities for us at Consensys are centered on developing mass-market applications that are useful to everyday people. Improving saving, spending, lending, and credit for the under and unbanked are clear goals for this year,” Lynch shared.

The convergence of these transformative narratives highlights Web3’s potential to redefine the digital economy. As these developments unfold, collaboration, education, and sustainability will be essential to shaping a thriving Web3 ecosystem.

Alongside these advancements, experts have also identified other potential narratives that could shape the industry’s trajectory in 2025. Explore these challenges and gain deeper insights into the future of Web3 with BeInCrypto’s expert analyses:
