Enum OpPooledTransaction

Source
pub enum OpPooledTransaction {
    Legacy(Signed<TxLegacy>),
    Eip2930(Signed<TxEip2930>),

}
Available on crate feature consensus only.
Expand description

All possible transactions that can be included in a response to GetPooledTransactions. A response to GetPooledTransactions. This can include a typed signed transaction, but cannot include a deposit transaction or EIP-4844 transaction.

The difference between this and the OpTxEnvelope is that this type does not have the deposit transaction variant, which is not expected to be pooled.

Variants§

§

Legacy(Signed<TxLegacy>)

An untagged TxLegacy.

§

Eip2930(Signed<TxEip2930>)

A TxEip2930 transaction tagged with type 1.

§

Eip1559(Signed<TxEip1559>)

A TxEip1559 transaction tagged with type 2.

§

Eip7702(Signed<TxEip7702>)

A TxEip7702 transaction tagged with type 4.
