# Multichain compatibility ### **EVM (Ethereum)** Ethereum-based addresses are interoperable across different Ethereum-compatible chains. If a blockchain uses the EVM, it can reuse the same Ethereum addresses. This is a very interesting point, because if we know a user's EVM address, we can use it via different providers on any string. A single implementation will enable us to write code that can be used on multiple chains. ### **Substrate (Polkadot/Parachains)** Substrate-based chains have their own address formats, and there isn't a universal Substrate address that works across all Substrate-based chains. Each Substrate chain has its own address space. To obtain precise information about the addressing standards for specific parachains, it is recommended to refer to the documentation of the individual parachain --- # Agent Instructions: 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: ``` GET https://jungle-toolkit.gitbook.io/evm-xcm-jungle-toolkit/build-an-evm+substrate-wallet-compatible-architecture-in-your-dapp/two-different-standards/multichain-compatibility.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
