optimism
only.Expand description
Additional TxEnv fields for optimism.
Fields§
§source_hash: Option<FixedBytes<32>>
The source hash is used to make sure that deposit transactions do not have identical hashes.
L1 originated deposit transaction source hashes are computed using the hash of the l1 block hash and the l1 log index. L1 attributes deposit source hashes are computed with the l1 block hash and the sequence number = l2 block number - l2 epoch start block number.
These two deposit transaction sources specify a domain in the outer hash so there are no collisions.
mint: Option<u128>
The amount to increase the balance of the from
account as part of
a deposit transaction. This is unconditional and is applied to the
from
account even if the deposit transaction fails since
the deposit is pre-paid on L1.
is_system_transaction: Option<bool>
Whether or not the transaction is a system transaction.
enveloped_tx: Option<Bytes>
An enveloped EIP-2718 typed transaction. This is used
to compute the L1 tx cost using the L1 block info, as
opposed to requiring downstream apps to compute the cost
externally.
This field is optional to allow the TxEnv to be constructed
for non-optimism chains when the optimism
feature is enabled,
but the CfgEnv optimism
field is set to false.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
