ERC-8128: Your Ethereum Wallet Might Soon Be Your Only Login.

Let me start with something that's been bugging me for years. I work with APIs constantly. And every time I spin up a new project that touches any kind of Web3 functionality, I end up doing this awkward dance — my users authenticate on-chain with their wallets, and then I also have to issue them a JWT or an API key to handle the off-chain stuff. Two separate identity systems. Two separate trust models. Two separate things that can break. It feels wrong. And apparently, I'm not the only one who thinks so. Enter ERC-8128 In January 2026, a proposal quietly landed in the Ethereum ERCs repository that, if it gains traction, could fundamentally change how we think about authentication in Web3 apps. ERC-8128 proposes a standard for signing HTTP requests using Ethereum accounts . Not just signing a login message once (that's what Sign-In with Ethereum does). Not just proving wallet ownership. Every. Single. HTTP request — signed with your Ethereum key, verified by the server, no stored creden
