# Ethereum Compatibility
## We Support Ethereum Equivalence
### 1. Development Tools
Any tooling that can run on Ethereum will run seamlessly within the Klaytn ecosystem by making Klaytn’s technical stack equivalent, from an interfacing and execution perspective, to the existing Ethereum stack. New tooling created in the Klaytn ecosystem could be reciprocally adopted within the Ethereum ecosystem.
### 2. EVM and API
By building on top of existing Ethereum stacks; we inherit any improvements made to the open-source codebases of EVM and supporting libraries. Supporting such equivalent opcodes and stack logic in the Klaytn EVM environment would see execution behaviour is guaranteed equivalent; and supporting a set of JSON-RPC APIs with equivalent endpoint payload syntax guarantees full Ethereum interfacing equivalence.
### 3. Core Development Contribution
Supporting Ethereum equivalence translates most to the mutual benefit to both the Klaytn and Ethereum ecosystems. The majority of Ethereum Improvement Proposals (EIPs) could be migrated and adopted to the Klaytn core development agenda, and in turn Klaytn Improvement Proposals (KIPs) could contribute to the advancement of Ethereum and EVM. When the development community contributes to one ecosystem, they are indeed contributing to both.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://archive-docs.klaytn.foundation/misc/klaytn2/ethereum-compatibility.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
