ErrGasLimit is returned if a transaction's requested gas limit exceeds the maximum allowance of the current block.

ErrInvalidSender is returned if the transaction contains an invalid signature.

ErrNegativeValue is a sanity error to ensure no one is able to specify a transaction with a negative value.

ErrOverdraft is returned if a transaction would cause the senders balance to go negative thus invalidating a potential large number of transactions.

ErrOversizedData is returned if the input data of a transaction is greater than some meaningful limit a user might use.

ErrReplaceUnderpriced is returned if a transaction is attempted to be replaced with a different one without the required price bump.

ErrTxPoolOverflow is returned if the transaction pool is full and can't accept another remote transaction.

ErrUnderpriced is returned if a transaction's gas price is below the minimum configured for the transaction pool.

Config are the configuration parameters of the transaction pool.
