The Risk of Mini Apps Fragmenting the Blockchain Ecosystem

In a recent event in the Asia-Pacific region, an important warning was discussed about how Mini Apps could create fragmented and closed ecosystems within the blockchain space. The co-founder of Ethereum pointed out a critical concern: when decentralized applications rely on proprietary interfaces instead of open standards, they risk becoming prisoners within specific platforms or clients.

The Concept of Walled Garden in Practice

This phenomenon, known as “Walled Garden” (, represents a significant deviation from the decentralized philosophy. When developers build Mini Apps on proprietary layers, users lose the fundamental freedom that blockchain technology promises. The core question is simple: if a user cannot freely move their assets and data between different applications and platforms, what is the real advantage over traditional centralized systems?

Mini Apps and Silent Centralization

The growing adoption of closed APIs by Mini App platforms exacerbates this problem. Instead of using standardized interfaces that would enable interoperability between systems, many of these applications opt for proprietary solutions. This approach compromises the concept of “bring your own keys” — one of the fundamental promises of blockchain.

The Impact on the Original Vision of Blockchain

The concern goes beyond technical issues. Closed systems like these undermine the core purpose of blockchain technology: to offer real guarantees to users and to keep access open and transparent. When Mini Apps function as walled gardens, blockchain ceases to be a decentralized revolution and becomes just another centralized platform with a modern technology label.

Why This Matters Now

Ecosystem fragmentation harms not only individual users but also the healthy development of the entire industry. If the growth of Mini Apps means the gradual death of interoperability, we will be wasting the transformative potential of blockchain.
