Caution

Cautions when using eth namespace apis in Klaytn.

Klaytn supports eth namespace APIs, so developers using Ethereum based SDKs or tools now can easily migrate their existing projects to Klaytn. (e.g. You can replace the endpoint URL in the Ethereum tools to point to a Klaytn node.)

But due to the fundamental design differences existing between Klaytn and Ethereum, some APIs cannot be fully supported. (e.g. some fields have always zero value)

This document describes the limitations of those APIs.

Block Header

Related APIs: eth_getHeaderByNumber, eth_getHeaderByHash.

• Please read the description ⚠️ carefully.

• The ✅ icon in the description denotes that the field used in the same way as in Ethereum.

Ethereum Header Field	Klaytn Header Field	Description
baseFeePerGas	(added)	⚠️ This field always has the value 0x0 because Klaytn does not have a baseFeePerGas scheme.
difficulty	(added)	⚠️ This field corresponds to blockScore in the Klaytn header, which is fixed to 0x1. This is because Klaytn's consensus mechanism is not based on PoW, indicating the technical concept of block difficulty is not applicable to Klaytn core.
extraData	extraData	⚠️ This field always has the value 0x indicating the empty value. Owing to the fact that Klaytn's extraData contains consensus data such as validators addresses, validators signatures, and proposer signature, it is not applicable to eth namespace API.
gasLimit	(added)	⚠️ This field always has the value 0xe8d4a50fff(=999999999999 in decimal), which is an arbitrary figure since Klaytn has no GasLimit. At the time of writing, this figure is 30 times higher than the block gas limit of Ethereum. Please refer to Computation Cost for more details.
gasUsed	gasUsed	✅ A scalar value equal to the total gas used in transactions in this block.
	governanceData(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Block Header.
hash	hash	✅ A hash of the block.
logsBloom	logsBloom	✅ The bloom filter for the logs of the block. null when it is pending block.
miner	(added)	⚠️ This field returns the block proposer's address, because Klaytn's consensus mechanism is PBFT, which has a block proposer instead of miners.
mixHash	(added)	⚠️ This field always has zeroHash (0x00...) because Klaytn's consensus mechanism is not based on PoW.
nonce	(added)	⚠️ This field always has zeroNonce (0x00...) because Klaytn's consensus mechanism is not based on PoW.
number	number	✅ The block number.
parentHash	parentHash	✅ The hash of the parent block.
receiptsRoot	receiptsRoot	✅ the root of the receipts trie of the block.
	reward(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Block Header.
sha3Uncles	(added)	⚠️ This field always has 0x1dcc4de8dec75d7aab85b567b6ccd41ad312451b948a7413f0a142fd40d49347, which is the Keccak256 hash of the RLP-encoded bytes of the list containing empty block header because there are no uncles blocks on Klaytn.
size	size	✅ The size of this block in bytes.
stateRoot	stateRoot	✅ The root of the final state trie of the block.
timestamp	timestamp	✅ The unix timestamp for when the block was collated.
	timestampFoS(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Block Header.
totalDifficulty	(added)	⚠️ The total difficulty of the chain until the querying block.
transactionsRoot	transactionsRoot	✅ The root of the transaction trie of the block.

Block

Related APIs: eth_getBlockByHash, eth_getBlockByNumber, eth_getUncleByBlockHashAndIndex, eth_getUncleByBlockNumberAndIndex.

Since Block contains fields of Header and header has already been covered above, this section describes the remaining fields of the block except for header.

• Please read the description ⚠️ carefully.

• The ✅ icon in the description denotes that the field used in the same way as in Ethereum.

Ethereum Header Field	Klaytn Header Field	Description
	voteData(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Block.
uncles	(added)	⚠️ This field always has the value [] because there is no technical concept of uncles block in Klaytn core.
transactions	transactions	✅ Array of transaction objects, or 32 Bytes transaction hashes depending on the last given parameter.

Transaction

Related APIs: eth_getTransactionByHash, eth_getTransactionByBlockHashAndIndex, eth_getTransactionByBlockNumberAndIndex, eth_pendingTransactions.

There are lots of transaction types in Klaytn, and fields of data structure vary based on the type.

So you have to check how various types of Klaytn transaction are converted as Ethereum transaction because during converting process some fields are omitted or added with zero or dummy values. That means Some important information(in terms of Klaytn) will be lost during converting.

Please note that we define EthereumLegacyTransaction in this document as the Ethereum transaction format before EIP-2718.

When you try to query Klaytn transactions via eth namespace JSON-RPC apis, Klaytn transactions will be return as Ethereum Legacy Transaction type.

This document describes the details of converting process (Klaytn transactions -> Ethereum Legacy Transaction).

• Please read the description ⚠️ carefully.

Common Fields

Regardless of various Klaytn transaction type, there are common fields. This section describes how that common fields are served as Ethereum Legacy Transaction.

Ethereum Legacy Transaction Field	Klaytn Transaction Field	Description
blockHash	blockHash	✅ Block hash.
blockNumber	blockNumber	✅ Block number.
from	from	✅ Address of the sender.
gas	gas	✅ Gas provided by the sender.
gasPrice	gasPrice	⚠️ Also known as Unit Price in Klaytn's context, this value is determined in the system via the governance processes.
hash	hash	✅ Transaction hash.
input	(covered in below sections)	The description of this field is covered in the detailed transaction items below.
nonce	nonce	✅ The number of transactions made by the sender prior to this one.
	senderTxHash(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Legacy Transaction.
	signatures(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Legacy Transaction.
to	(covered in below sections)	The description of this field is covered in the detailed transaction items below.
transactionIndex	transactionIndex	⚠️ Almost same with Ethereum but unlike Ethereum, Klaytn returns integer as it is when its pending.
value	(covered in below sections)	The description of this field is covered in the detailed transaction items below.
type	type(converted)	⚠️ In Klaytn, type returns the transaction type in string (e.g. "LegacyTransaction"), but it has been converted to hexadecimal (e.g. 0x0) to match Ethereum. Transaction types that are only valid in Klaytn always return 0x0.
	typeInt(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Legacy Transaction.
v	(added)	⚠️ Klaytn supports MultiSig so transaction in Klaytn can have more than one signature. signatures[0].V is used as the value of the field v.
r	(added)	⚠️ Klaytn supports MultiSig so transaction in Klaytn can have more than one signature. signatures[0].R is used as the value of the field r.
s	(added)	⚠️ Klaytn supports MultiSig so transaction in Klaytn can have more than one signature. signatures[0].S is used as the value of the field s.

Transaction Receipt

Related APIs: eth_getTransactionReceipt.

By default, the fields in the Klaytn Transaction Receipt are different depending on the transaction type. Because there are lots of transaction types in Klaytn, fields of transaction receipt vary based on the transaction type.

When you try to query Klaytn transaction receipts via eth namespace JSON-RPC apis, Klaytn TransactionReceipt will be returned as Ethereum Transaction Receipt.

This document describes the details of converting process (Klaytn Transaction Receipt -> Ethereum Transaction Receipt).

• Please read the description ⚠️ carefully.

• The ✅ icon in the description denotes that the field used in the same way as in Ethereum.

blockHash	blockHash	✅ Block hash.
blockNumber	blockNumber	✅ Block number.
contractAddress	contractAddress	✅ The contract address created, if the transaction was a contract creation, otherwise - null.
cumulativeGasUsed	(added)	⚠️ The total amount of gas used when this transaction was executed in the block. It is provided with the same meaning as the Ethereum field.
effectiveGasPrice	(added)	⚠️ Since Klaytn uses a fixed gas price policy, the gasPrice value is returned. gasPrice(also called Unit Price) is set in the system by the governance.
from	from	✅ Address of the sender.
	gas(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Transaction Receipt.
gasUsed	gasUsed	✅ the amount of gas used by this specific transaction alone.
	gasPrice(omitted)	⚠️ This field is omitted because this field does not exist in Ethereum Transaction Receipt.
logs	logs	✅ Array of log objects generated by transactions.
logsBloom	logsBloom	✅ Bloom filter for light clients to quickly retrieve related logs.
