-Package ante defines the SDK auth module's AnteHandler as well as an internal
-AnteHandler for an Ethereum transaction (i.e MsgEthereumTx).
-
-During CheckTx, the transaction is passed through a series of
-pre-message execution validation checks such as signature and account
-verification in addition to minimum fees being checked. Otherwise, during
-DeliverTx, the transaction is simply passed to the EVM which will also
-perform the same series of checks. The distinction is made in CheckTx to
-prevent spam and DoS attacks.
