Expand description

Optimism transaction validation error.

Variants§

§

Base(InvalidTransaction)

§

DepositSystemTxPostRegolith

System transactions are not supported post-regolith hardfork.

Before the Regolith hardfork, there was a special field in the Deposit transaction type that differentiated between system and user deposit transactions. This field was deprecated in the Regolith hardfork, and this error is thrown if a Deposit transaction is found with this field set to true after the hardfork activation.

In addition, this error is internal, and bubbles up into a OptimismHaltReason::FailedDeposit error in the revm handler for the consumer to easily handle. This is due to a state transition rule on OP Stack chains where, if for any reason a deposit transaction fails, the transaction must still be included in the block, the sender nonce is bumped, the mint value persists, and special gas accounting rules are applied. Normally on L1, EVMError::Transaction errors are cause for non-inclusion, so a special OptimismHaltReason variant was introduced to handle this case for failed deposit transactions.

§

HaltedDepositPostRegolith

Deposit transaction haults bubble up to the global main return handler, wiping state and only increasing the nonce + persisting the mint value.

This is a catch-all error for any deposit transaction that is results in a OptimismHaltReason error post-regolith hardfork. This allows for a consumer to easily handle special cases where a deposit transaction fails during validation, but must still be included in the block.
