Are my items safe on Immutable X?

Yes. A layer 2 solution means Immutable X is secured by Ethereum (which is layer 1). We never compromise on Ethereum L1 validating every Immutable X transaction. Rollups consist of a smart contract and an environment to process trades. This environment generates a proof and sends that proof to the smart contract on L1.
