Polkadot has improved its asset transfer capabilities between blockchains with XCM version 3, applicable to both conventional tokens and NFTs.
Improved programmability is the primary emphasis of the latest release, opening up a wide variety of new possibilities for using tokens across different chains. For example, tokens can be locked on one chain and released on another.
