XCM is one of Polkadot’s most powerful features. Through XCM, @Polkadot can connect rollup-based chains into an organically integrated structure. This stands in stark contrast to other ecosystems, where rollups are often implemented in fragmented and incompatible ways due to the lack of shared standards.

What’s more, this core feature—XCM—is now available within Polkadot’s smart contract environment. This is comparable to having interoperability technology natively embedded in an Ethereum-like chain, fundamentally solving the security issues that have often arisen when bridging between chains in the past.

With XCM support in Polkadot smart contracts, developers are presented with an entirely new paradigm—one that redefines how smart contracts can be built and interact across chains.
