Open-source, self-custodial wallet and Ethereum interface launched in 2015
MyEtherWallet (MEW) is an open-source, client-side interface and non-custodial cryptocurrency wallet that launched in 2015. Originally created as an early web interface for Ethereum, it now lets users hold, swap, stake, and interact with smart contracts across Ethereum, EVM networks, and major non-EVM blockchains.
The platform was founded in November 2015 by Kosala Hemachandra, who serves as CEO and was educated at California State University, Northridge. Operating out of Los Angeles, United States, the team originally launched the client-side tool to simplify transactions on the nascent Ethereum network.
MyEtherWallet runs as a self-custodial platform where private keys remain under the control of the user on their local device. It is accessible through a web interface and dedicated mobile applications on iOS and Android. Alongside mainnet Ethereum, the software supports layer-2 rollups and sidechains including Arbitrum, Optimism, Base, zkSync Era, and Polygon, as well as BNB Smart Chain, Ethereum Classic, Polkadot, Bitcoin, and Solana. Users can execute decentralized swaps through third-party aggregators, bridge tokens, and connect to decentralized applications using WalletConnect.
The core interface is free to use. Users pay standard variable blockchain network gas fees for on-chain transfers, with speeds configurable before broadcasting transactions. For decentralized swaps, fees from liquidity aggregators are presented in the offer summary prior to confirmation. MyEtherWallet is available globally, and using the self-custodial interface requires no account creation or identity verification.
The domain was registered in August 2015, and the interface went live in November 2015. On April 24, 2018, an upstream BGP routing hijack directed against Amazon Route 53 rerouted traffic from the site to a malicious DNS server. The incident compromised 198 users and led to the theft of approximately 215 ETH. Because the software operates client-side and client keys are stored locally, users face standard self-custodial risks such as seed-phrase exposure and domain-spoofing phishing attacks.
MyEtherWallet provides open-source self-custody across Ethereum, EVM networks, Bitcoin, and Solana, but users assume complete personal responsibility for guarding against frontend phishing and route hijacks.
MyEtherWallet (MEW) launched in 2015 as one of the original client-side interfaces for Ethereum, founded by Kosala Hemachandra. It remains a self-custodial portal where users control their private keys locally or through connected hardware devices. Instead of storing funds or user credentials, MEW generates transactions locally and broadcasts them directly to the blockchain. Over time, the platform expanded from its initial web portal into mobile applications for iOS and Android, broadening its support past core Ethereum to EVM networks including Arbitrum, Optimism, Base, zkSync Era, Polygon, and BNB Smart Chain, as well as separate ecosystems like Bitcoin and Solana.
Key strengths include its open-source codebase, long operating history, and free core wallet interface. Users control their seed phrases and private keys without mandatory account creation or identity verification. In-app utilities handle decentralized swaps and token bridging by connecting directly to external liquidity protocols, presenting all network gas fees and aggregator costs before execution.
The interface model introduces distinct operational trade-offs:
MyEtherWallet provides open-source access to Ethereum, EVM networks, decentralized applications, and hardware wallet integrations.

Community discussions mainly center around troubleshooting wallet access, derivation paths, and app errors rather than broad praise. Users frequently encounter bugs such as energy collection failures and unexpected geographic access restrictions.
“MEW - Collect today’s energy issue Hi, I’ll being using this application for a while but recently every time I tried to collect the energy it’s not working properly. I’m using this wallet on iOS 26.5.”
“Blocked in Australia Hi all, just went to get into my wallet after not using it for a while and it says I'm blocked from being in a restricted jurisdiction. Support just gave me a link to news, but I can't even open that.i had nothing in it, so no big deal, I only use it for poker.”
“mew mobile wallet keeps crashing Since today I can no longer start mew wallet on my android phone, every once in awhile it will ask for my pin but crash imminently”
“MEW Wallet - Unstake Lido Hi, Absolutely clueless here. I was about to follow steps to unstake Lido back into my MEW Wallet and learned of the issue accessing the website via the UK. The plan was to add a browser extension to sort. Seems I can't do that now.”
Scam warning: Malicious browser extensions and phishing pages have targeted keystore files to access and compromise users' wallets.
