The developers of the Mosaic blockchain have successfully implemented on the Paseo testnet the transfer of the MOS token from the Mosaic chain to the AssetHub of the Polkadot ecosystem using XCM.

XCM (Cross-Consensus Messaging) is essentially the “common language” of Polkadot: it allows different parachains to securely move data and assets (tokens) between each other. This is the key to interoperability, as it allows our MOS token to go beyond the boundaries of our own chain.

AssetHub is a central chain in the ecosystem, specifically optimized for managing, recording and moving assets.

Although other parachains can build on assets managed on the Asset Hub, the Asset Hub serves as a trusted central base and is also the primary backup location for DOT in cross-chain operations. The latter means that the actual collateral of DOT is registered in a central location, the Asset Hub, and is where the movement between chains takes place. On other parachains, only a “mapped” version of this appears, while the original asset remains registered as the underlying collateral on the AssetHub.

In parallel, the developers have also created a TMOS–PAS (test Mosaic and Paseo, i.e. test DOT) liquidity pool on the Paseo testnet, which allows for smooth switching between tokens and lays the foundation for later DeFi operations.

The next step will be to start developing the frontend interface so that all this can be accessed in a simple and user-friendly way soon.
