The Moonbeam XCM SDK enables developers to easily transfer assets between chains, either between parachains or between a parachain and the relay chain, within the Polkadot/Kusama ecosystem.
Additionally, the Moonbeam MRL SDK allows users to easily transfer liquidity into and across the Polkadot ecosystem from other ecosystems like Ethereum. It builds on the XCM SDK by adding necessary functions to support MRL.
