Variants

TransactionHalt = 1

Summary

Transaction execution reverted and gas was burned.

Description

This error occurs when a transaction execution is reverted due to an error in the anvil-zksync virtual machine execution and all gas is burned. This is a wrapper error that contains a more specific error inside it.

The VM may fail for various reasons including:

• Account validation failures (signature issues, nonce mismatches)
• Paymaster-related errors (when testing account abstraction features)
• Gas limit exceedance
• Storage access limitations
• Contract execution failures

When using anvil-zksync for testing, these failures are valuable signals that help you identify issues with your contracts or transactions before deploying to the real ZKSync network.

TransactionValidationFailed = 10

Summary

Transaction validation failed in anvil-zksync.

Description

This error occurs when a transaction validation is failed and it is not executed. This is a wrapper error that contains a more specific validation error inside it, which provides details about the cause of failure.

The validation may fail for various reasons including:

• Gas limit exceedance
• Invalid gas limit value
• maxFeePerGas exceeding maxPriorityFeePerGas, and so on.

When using anvil-zksync for testing, these errors are valuable signals that help you identify issues with your contracts or transactions before deploying to the real ZKSync network.

TransactionGasEstimationFailed = 11

Summary

Transaction gas estimation failed in anvil-zksync.

Description

This error occurs when a gas estimation for transaction failed. This is a wrapper error that contains a more specific gas estimation error inside it, which provides details about the cause of failure.

TimestampBackwardsError = 20

Summary

Requested block timestamp is earlier than the current timestamp.

Description

This error occurs when attempting to set a future block timestamp to a value that is earlier than the timestamp of the most recently mined block.

In anvil-zksync, block timestamps must always increase monotonically. This simulates the behavior of real blockchain networks where time only moves forward. Each new block must have a timestamp greater than its predecessor.

Anvil-zksync provides methods to manipulate time for testing purposes (like evm_increaseTime and evm_setNextBlockTimestamp), but these can only move time forward, never backward.

Block timestamps in anvil-zksync are used by:

• Smart contracts that rely on block.timestamp for time-dependent logic
• System contracts that need to track event timing
• Time-locked functionality in DeFi applications and governance protocols

When testing contracts that have time-dependent logic, it’s important to ensure that any manipulated timestamps move forward in time, not backward.

SerializationError = 30

Summary

Failed to serialize transaction request into a valid transaction.

Description

This error occurs when anvil-zksync is unable to convert a transaction request into a properly formatted transaction object. This typically happens during transaction creation or gas estimation when the request contains invalid or incompatible parameters.

GenericError = 0

Implementations

impl AnvilNodeCode

pub const fn from_repr(discriminant: u32) -> Option<AnvilNodeCode>

impl Clone for AnvilNodeCode

fn clone(&self) -> AnvilNodeCode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AnvilNodeCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'_enum> From<&'_enum AnvilNode> for AnvilNodeCode

fn from(val: &'_enum AnvilNode) -> AnvilNodeCode
