# Crosschain Portal The in-house cross chain portal allows players to transfer BCMC and Monster NFTs across different blockchains with ease. A fee will be charged for each porting and will be collected in BCMC. To fund the gas fee on the target chain, the player has the option to convert BCMC to their target native chain currency to pay for the target chain’s gas fees. This service allows for a fast and convenient onboarding of players to the new chain. The game will initially be deployed on ETH, BSC, and Polygon. We will expand to Heco, Moonriver, and Ambros (our in-house EVM chain) in V2 of BCMH. Non-EVM chains will come later. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
