The following smart contract is called GasMovr, which is an Ethereum-based contract that allows users to deposit and withdraw native tokens across different chains. It includes functions for depositing and withdrawing tokens, setting chain configurations, and granting/rejecting sender roles. The contract also includes a batch send function for sending tokens to multiple addresses at once. The contract is Ownable and Pausable, and uses OpenZeppelin libraries for access control and security.
