SKALE
SKLEthereum-native elastic blockchain network with zero gas fees for users
Technology Stack
Introduction to SKALE
SKALE Network provides an unusual scaling solution for Ethereum: elastic sidechains that offer zero gas fees for end users. Rather than a single Layer 2, SKALE creates a network of configurable chains that applications can spin up according to their needs—blockchain-as-a-service with Ethereum security.
The “zero gas” model—where applications pre-pay for user transactions—removes a major friction point for mainstream adoption. This approach has attracted gaming projects in particular, where frequent transactions and microtransactions make per-transaction fees impractical. SKALE uses smart contracts for its core functionality.

Conclusion
SKALE’s elastic sidechain model with zero user gas offers a genuinely differentiated approach to Ethereum scaling. The focus on gaming—where transaction frequency and user experience are paramount—represents smart market positioning.
The trade-off is a different security model than rollups, with applications trusting SKALE validators rather than inheriting full Ethereum security for every transaction. For many use cases, particularly gaming, this trade-off is acceptable.
For gaming developers seeking Ethereum-connected infrastructure without user gas friction and for applications that can benefit from dedicated chains, SKALE provides unique capabilities—though understanding the security model differences from rollups is important.
