Transaction validation errors

Variants§

§

GasLimitTooLow = 0

The transaction gas limit is too low

§

GasLimitTooHigh = 1

The transaction gas limit is too hign

§

GasPriceTooLow = 2

The transaction gas price is too low

§

PriorityFeeTooHigh = 3

The transaction priority fee is too high

§

BalanceTooLow = 4

The transaction balance is too low

§

TxNonceTooLow = 5

The transaction nonce is too low

§

TxNonceTooHigh = 6

The transaction nonce is too high

§

InvalidFeeInput = 7

The transaction fee input is invalid

§

InvalidChainId = 8

The chain id is incorrect

§

InvalidSignature = 9

The transaction signature is invalid

§

EmptyAuthorizationList = 10

EIP-7702 transaction has empty authorization list

According to EIP-7702 specification, transactions with empty authorization lists are invalid. This validates the fundamental requirement that EIP-7702 transactions must include at least one authorization to be valid.

§

AuthorizationListTooLarge = 11

EIP-7702 authorization list exceeds maximum size

To prevent DoS attacks, authorization lists are limited to a maximum of 255 items. This provides reasonable authorization functionality while preventing excessive resource consumption during validation and processing.

Rationale

  • Geth: No explicit limit, relies on 32KB transaction size limit (~160 authorizations practical maximum)
  • EIP-7702 Spec: No defined limit, left to implementations

This explicit limit is more predictable than implicit limits based on transaction size, providing developers with clear boundaries and better DoS protection.

§

UnknownError = 12

Unknown error
