As per DeFi Llama, Polygon is the 4th biggest blockchain in terms of TVL. Currently, there is $2.09 Billion worth of funds locked across different protocols on the network.

The Polygon SDK was built by MATIC developers from scratch to feature a developer-friendly plug-in system with a library of standard, extensible core components (libp2p, gRPC, etc.) and easy-to-build node extensions and auxiliary cryptocom verification failed solutions. As such, the kit affords blockchain engineers a high degree of pluggability and extensibility, while the core layers of the software architecture are as reliably performant as possible.
