Starknet has unveiled the SN Stack, a modular toolkit designed to aid developers in creating appchains. It includes essential components such as Starknet OS for blockchain operation, CairoVM for executing smart contracts, and Blockifier for block building. This marks a significant enhancement in the modularity of the ecosystem.

The SN Stack provides three unique options to cater to different developmental needs: Madara offers an open-source flexible framework, Dojo is optimized for gaming and advanced on-chain applications, while StarkWare Sequencer delivers the entire Starknet infrastructure for HIGH-performance dApps.

In 2024, the Layer-2 ecosystem saw significant growth with rollups exceeding 100 in number. This surge reflects a heightened demand for scalable solutions. Modular Layer-2 solutions are becoming increasingly popular due to developer tools offered by projects like Optimism, Arbitrum, ZKsync, and now Starknet, with its innovative SN Stack toolkit.
