Module evm

Modules§

evm_transaction: This module provides functionality related to Ethereum Virtual Machine (EVM) transactions. It includes the core transaction logic and utility functions for handling EVM transactions. This module defines the EvmRelayerTransaction struct and its associated functionality for handling Ethereum Virtual Machine (EVM) transactions. It includes methods for preparing, submitting, handling status, and managing notifications for transactions. The module leverages various services and repositories to perform these operations asynchronously.
price_calculator: Gas price calculation module for Ethereum transactions.
replacement: This module contains the replacement and resubmission functionality for EVM transactions. It includes methods for determining replacement pricing, validating price bumps, and handling transaction compatibility checks.
status: This module contains the status-related functionality for EVM transactions. It includes methods for checking transaction status, determining when to resubmit or replace transactions with NOOPs, and updating transaction status in the repository.

EvmRelayerTransaction
PriceCalculator: Primary struct for calculating gas prices with an injected EvmGasPriceServiceTrait.
PriceParams

calculate_min_bump: Safely calculates the minimum required gas price for a replacement transaction. Uses saturating arithmetic to prevent overflow and maintains precision.
calculate_replacement_price: Calculates replacement pricing with fresh market rates.
check_transaction_compatibility: Checks if an old transaction and new transaction request are compatible for replacement.
determine_replacement_pricing: Determines the pricing strategy for a replacement transaction.
get_age_of_sent_at: Gets the age of a transaction since it was sent.
has_enough_confirmations: Helper function to check if a transaction has enough confirmations.
has_explicit_prices: Checks if an EVM transaction data has explicit prices.
is_noop: Checks if a transaction is already a NOOP transaction
is_pending_transaction
is_transaction_valid: Checks if a transaction is still valid based on its valid_until timestamp.
make_noop: Updates an existing transaction to be a “noop” transaction (transaction to self with zero value and no data) This is commonly used for cancellation and replacement transactions For Arbitrum networks, uses eth_estimateGas to account for L1 + L2 costs
too_many_attempts: Checks if a transaction has too many attempts
too_many_noop_attempts: Checks if a transaction has too many NOOP attempts
validate_explicit_price_bump: Validates explicit gas prices from a replacement request against bump requirements.
