The wallet project collaborated with the data and digital identity supplier Spruce.
Developers in 2021 initially proposed Ethereum Improvement Proposal (EIP) 4361.
Users may now safely utilize their Ethereum-based cryptocurrency wallet using the “Sign In with Ethereum” option recently added to MetaMask.
In an effort to standardize how Ethereum account users verify themselves on off-chain services, the widely used web3 wallet has adopted the EIP-4361 protocol. The wallet project collaborated with the data and digital identity supplier Spruce to provide this feature.
Decentralized Substitute
EIP-4361 allows users of wallet projects like MetaMask to authenticate themselves on websites by signing a common message format. While accessing a supported website, a pop-up will appear asking the user to validate the domain name, session data, and security methods (such as a nonce) used to prevent unauthorized access. This provides a decentralized substitute for traditional identifiers like email and phone numbers.
MetaMask stated:
“This is part of our ongoing effort to make confirmations more legible to our community. Our implementation also offers a ‘domain binding’ feature, which detects signatures/approvals from malicious URLs.”
To facilitate the use of Ethereum wallets for off-chain services, developers in 2021 initially proposed Ethereum Improvement Proposal (EIP) 4361, also known as Sign In with Ethereum.
The majority of conventional websites rely on identity providers like major internet corporations and email providers in order to log users into widely used non-blockchain-based services. These identity providers are centralized businesses that have complete control over the user IDs they store.
Moreover, note that MetaMask is not the only wallet service that use these kinds of safeguards. Phantom, another wallet service, implemented support for Solana blockchain’s counterpart of ERC-4361 in February.
