![]() If the blockchain has nothing or little to do with Ethereum, it is unlikely to be usable with MetaMask.This Is How to Recover MetaMask Wallet with Secret Recovery Phrase The most obvious example would be Bitcoin, whose address format is completely different. As flexible as MetaMask is, you cannot interact with non-EVM-compatible networks on completely different blockchains. Non-EVM-compatible networks: stay away.Others, like Avalanche, have multiple chains with varying levels of EVM support ( you should only interact with Avalanche C-Chain on MetaMask). The Harmony network, for example, is fully EVM-compatible, but allows users to switch between an 0x and one1 version of their address (although the number which follows this prefix is the same). Just because a network is EVM-compatible does not necessarily mean it uses an 0x address in all circumstances. EVM-compatible networks with different formats.Whilst MetaMask is a flexible passport to accessing Ethereum and EVM-compatible chains, there are some cases where you need to exercise caution when it comes to address formats: You'd need to bridge the tokens over separately.Ĭheck out our Field Guide to Bridges for more information. However, you would not be able to use these tokens on Ethereum, despite the ease with which you can switch over to mainnet in MetaMask. (There are some cases where you won't lose them, but in most scenarios, you will.) You could, for instance, send tokens on Polygon to your MetaMask address, and be able to view them in MetaMask - presuming you have the Polygon network and the tokens themselves added. This is in addition to the fact you should never send tokens straight from one network to another without bridging. Interacting with networks that have different address formats: be careful!ĭon't use MetaMask with any addresses that don't use the Ethereum format, either when sending or receiving. Follow the link to the network you're investigating to read more about bridging, tokens, and the nuances of its use. A network's native tokens are unlikely to be interchangeable with the (ERC-20) version that you can send and receive on MetaMask, for example.įor information on some of the most prominent EVM-compatible networks you can use with MetaMask, head to our network profiles page. However, the interplay of networks and tokens (particularly the question of ERC-20 variants of native tokens) can be complex and is not without risk, so please always do your research before sending a transaction. ![]() This means your MetaMask address on both Ethereum mainnet and BSC, for example, is exactly the same. Notice how your account and its address stay the same. Try it out: add a network to MetaMask, or switch over from one you've already added. Reflecting much of the same architecture naturally lends itself to sharing address formats too.ĭue to these shared characteristics, you can use MetaMask to interact with any other EVM-compatible network using the same address. Not all are derived directly from Ethereum, though - many were developed separately and designed for compatibility. This is because they're generally 'hard forks', based heavily on Ethereum's design, or share key fundamentals. How does this affect your daily use of MetaMask? Interoperability: use the same address on different networksĪs mentioned above, EVM-compatible networks all share the Ethereum address format. In computer science and many programming languages, the 0x prefix is used at the start of all hex numbers, as they are known, to differentiate them from decimal values. This means it has 16 characters at its disposal, hence the name base 16. Instead, the hexadecimal system uses the numerals 0-9 and the letters A-F. This is because the hexadecimal (base 16) system used to generate the address doesn't just use numerals, like our ten-digit decimal system. This address is a number, even though it also includes alphabetical characters. On Ethereum and other networks compatible with the Ethereum Virtual Machine (EVM), public addresses all share the same format: they begin with 0x, and are followed by 40 alphanumeric characters (numerals and letters), adding up to 42 characters in total. When you create a MetaMask account, or add a new account to your wallet, you're given a unique public address.
