Many people think that Rollup is an exclusive scaling solution for Ethereum, but @Polkadot has long built a more rigorous "suspicion-based Rollup" system at the protocol level — parachains (which are now Rollups).

It verifies transactions before execution, combining multi-layer endorsement and approval checks with data availability technology, achieving security finality on par with L1 in just ~18 seconds, and naturally supports XCM cross-chain interoperability. Compared to Optimistic / ZK Rollup, Polkadot doesn't just "support" it but redefines the relationship between scaling and security.

If you want to build your own Rollup, you don't have to start from scratch.

Polkadot provides tools to help you launch faster, scale securely, and connect natively to the entire ecosystem.
