In the ever-evolving world of blockchain technology, the future holds a promise of customized decentralized networks tailored for specific use cases. Sandeep Nailwal, the founder of Polygon, envisions a landscape where thousands of application-specific blockchains will be created to meet the diverse needs of consumers. This vision has led to the creation of Agglayer, a revolutionary concept aimed at unifying major blockchain applications.
“Thousands of custom-built chains”: Polygon founder on next generation of blockchains
The key to building successful blockchain applications lies in customization. Sandeep Nailwal emphasizes the importance of creating tailored solutions that cater to different consumer preferences. He predicts a future where a myriad of custom-built blockchains will emerge to serve niche purposes, revolutionizing the way applications are developed and utilized.
My take: in the very near future we’ll see thousands of chains custom built for very niche purposes. This customization is key for creating apps that different kinds of consumers will use.
I argue, every single meaningful App will be on its own dedicated block-space aka its own… https://t.co/cuog39VK4D

These specialized “appchains” will cater to specific use cases, ensuring that every significant application has its dedicated blockchain infrastructure.
Agglayer, a groundbreaking cross-network infrastructure protocol supported by the Polygon ecosystem, is set to revolutionize the blockchain industry by connecting and unifying purpose-built blockchains.
As previously reported by U.Today, Agglayer will serve as a vital link between different decentralized networks, offering a seamless experience for users across various blockchain platforms.
From DeFi to GameFi and Real World Assets (RWAs), the Agglayer ecosystem will encompass all existing and potential cryptocurrency use cases, providing a comprehensive solution for the diverse needs of the blockchain community.
What are appchains?
The concept of appchains has gained traction in recent years, with industry leaders recognizing the potential for customized decentralized networks. Unlike traditional monolithic blockchains like Bitcoin and Ethereum, appchains are tailored to specific applications, allowing for greater flexibility and scalability.
Major decentralized protocols have already begun migrating to their dedicated blockchains, such as Uniswap’s Unichain and dYdX’s dYdX Chain, signaling a shift towards more specialized and efficient blockchain solutions.
