Submission Details
Severity:
Users cannot migrate Bean to L2
Summary
There is uninitialized variable in BeanL1RecieverFacet.sol which blocks any migration of Bean:
@> uint256 constant EXTERNAL_L1_BEANS = 0;
address constant BRIDGE = address(0x4200000000000000000000000000000000000007);
address constant L1BEANSTALK = address(0xC1E088fC1323b20BCBee9bd1B9fC9546db5624C5);
/**
* @notice migrates `amount` of Beans to L2,
* issued to `reciever`.
*/
function recieveL1Beans(address reciever, uint256 amount) external nonReentrant {
...
require(
@> EXTERNAL_L1_BEANS >= s.sys.migration.migratedL1Beans,
"L2Migration: exceeds maximum migrated"
);
C.bean().mint(reciever, amount);
}
Impact
Bean cannot be migrated to L2 which is contrary to idea of Beanstalk L2 migration. Core functionality is broken, therefore High.
