Overview ¶
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.
