There seems to be a misconfiguration of the new Remote GSM on Arbitrum. The Arbitrum remoteGSM pairs GHO with bridged USDC.e, not native USDC. USDC.e is one of the assets on Arbitrum that’s going to be deprecated so this seems off.
The USDC GSM at 0x53E0cE250d06043414070100458546AaF4e284eD has underlying asset set to the StataToken 0xE6D5923281c89DC989D00817387292387552d5C1 that wraps the bridged USDC.e 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 instead of native USDC 0xaf88d065e77c8cC2239327C5EDb3A432268e5831
