Mean Finance enables users to Dollar Cost Average (DCA) one ERC20 into other ERC20. Now, as we said before, not all ERC20 tokens are supported by our oracle. If a token is not supported by the oracle, then a pair can't be created for it.
But, as it happens, some tokens that are incompatible with Mean Finance might be supported by the oracle provider.
Non-standard ERC20 tokens are incompatible with Mean Finance when balance can change on transfer, or over time. So for example fee-on-transfer tokens and rebasing tokens won't work correctly.
