I’m getting an error max code size exceeded. How can I resolve this?​

When deploying a contract, it must adhere to size limitations set by the blockchain. To resolve, you may try compressing your contract in the optimizer settings. If that still does not work, you will need to adjust your contract logic to fit within the maximum code size.
