Replace bridged USDC w/ native USDC

bridged USDC address - 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8
native USDC address - 0xaf88d065e77c8cC2239327C5EDb3A432268e5831

Native USDC should be supported since it's "the official version recognised by Arbitrum and is also directly redeemable 1:1 for US dollar with CEX support."
