⚡ Recommended focus areas for review Possible Issue The calculateBlockGasUsed function uses replace(/0x0+/, '0x') to remove leading zeros. This might incorrectly transform values like 0x0001 to 0x1 instead of 0x01. Ensure this behavior is intended. // Convert to hex and remove leading zeros const hexString = blockGasUsed.toHexString() return hexString.replace(/0x0+/, '0x')

[github-actions]

Suggestion: Ensure that the regular expression used for removing leading zeros does not inadvertently remove the '0' from '0x0' when the gas used is zero. [possible issue, importance: 7]

Suggested change

	return hexString.replace(/0x0+/, '0x')
	return hexString.replace(/^0x0+(?!$)/, '0x')
