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.

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.

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