Announcing the new SIWE.xyz

Sign in with Ethereum (ERC-4361) is the standard that powers the bridge between web2 and web3 for thousands of crypto (and non crypto) apps.

Our goal is to make sovereign cryptography a default option for authentication on the web.

We should own our finances, and we should own our web accounts. SIWE makes that possible, while ensuring users have great UX when doing so.

Already used by millions, including the likes of OpenRouter, Polymarket, MetaMask, Privy, OpenSea, and many many more.

The libraries we develop and support enable apps and wallets to seamlessly integrate the SIWE standard. If you have any questions or need help integrating, please reach out to any of us:

@caveman_onchain (aaron@siwe.xyz), @jalilwahdat (jalil@siwe.xyz), @yougogirl_eth (ygg@siwe.xyz).

Looking forward to working together on improving Ethereum UX.

🤯 it's happening guys... @OpenRouter (just acquired by @stripe) offers *Sign in with Ethereum* alongside Google and Github @signinethereum

great seeing the @Kleros_io forum just started using our new Sign in with Ethereum (@signinethereum) Discourse plugin for their forum! 👏👏👏

every crypto discourse forum should have SIWE as an option

published v4.2.0 of the @signinethereum TS library.

it loosens handling around EIP-55: we now automatically checksum addresses and don't throw for otherwise normalized lowercase/uppercase addresses.

this fixes custom patches many consuming apps like metamask had built for this.

thanks @sat_eth for the find!

a patch for our Rust implementation is coming too, as well as a big update of the Python library!

Just posted the Q1 2026 report for @ethidorg, an @ENS_DAO Service Provider building out the Ethereum identity stack. Best quarter we've ever had 🔥
Some highlights:

Grails 🏆 @grailsmarket
➡️ grails.app
Grails (the best @ensdomains manager & marketplace) grew *a lot*refined design, and users. And with results:

- Facilitated 99.35 ETH (~$205k) to the ENS DAO for registrations and extensions
- Facilitated more ETH to the ENS DAO than the ENS App on two days (Jan 26 and Feb 15) 👀
- Regularly facilitates more Extension events than the ENS App
- defi.eth sold for 15 ETH, law.eth sold for 7.5 ETH using Grails broker tools, etc

What users say about Grails
“Grails is a staggeringly strong ENS tool. What a beast.” - @DoggieWish

“Grails is an absolute game-changer for ENS and my daily ENS go-to. Seriously can’t recommend it enough.” - @bama_eth

“THE BEST! 🏆” - @iman_evm

Sign in with Ethereum @signinethereum
➡️ siwe.xyz
Full steam ahead, lots of updates:
- New Typescript lib

EthLeaderboard @ethleaderboard
➡️ ethleaderboard.com
Revived! Previously bricked by twitter API changes in 2023, but recently made possible again.

New version has improved ENS profile support, edit ENS records, EFP, better tweets from bot w/ autogenerated image, etc. Thanks to @gregskril for passing elements of the old version to us 🙏

ENSMarketBot @ensmarketbot
- Now the primary ENS market twitter bot by engagement and discussion
- GrailsAI✨ is out of beta and vastly improved. In reply to event tweets, it gives concise but deep analysis of what happened, w/ some comedy too 😂

Ethereum Follow Protocol @efp
➡️ efp.app
- efpv2 API: Total overhaul of the EFP Indexer database and API from the ground up, much faster & more reliable than before
- 7 new integrations bringing total to 83
- Crypto OG app @ethstatus integrated heavy use of EFP and ENS and highlighted this in their marketing campaign 🤝

Ethereum Identity Kit @ethidkit
➡️ ethidkit.com
React component lib and API with everything you need to easily add ENS, SIWE, and EFP to your app

- Improvements to profile cards, more socials options, Edit Profile button can now go to custom link, tagged ENS names in bios can now go to profiles on your app, etc

Misconfigured Wrapped Names
We identified 1,700 misconfigured wrapped names and paid ETH to fix them. Happy to help the ENS community on this one 🤝

amazing to see Conway Terminal not only providing each agent an Ethereum account but using the Sign in with Ethereum eip4361 standard for auth! 🤯 👉👉👉 see @signinethereum and siwe.xyz

Lots of shake-ups in crypto social these days, so let me re-introduce everyone to Ethereum Follow Protocol @efp and why I think it's a key primitive moving forward

Crypto social should be:
- Onchain and decentralized (need to say this)
- Use existing key protocols like hereum
- Enhance what we're already doing in crypto, rather than only directly competing with twitter

That's why i built EFP:
- Onchain social graph protocol for Ethereum accounts
- Ethereum accounts follow other ethereum accounts
- No special EFP accounts, just uses Ethereum accounts (which means you can follow accounts even if they've never used EFP)
- Doesn't have its own competing naming system, it simply uses ENS, the one true crypto naming system
- Fully onchain, decentralized, open source, no compromises
- 76 integrations and growing, including POAP, Snapshot, Superfluid, Tally, and more
- Funded by @ENS_DAO

EFP isn't a standalone app, it's *a primitive you embed into the apps we already have*, like ENS

Twitter clones are fine, but I'm more interested in adding a social layer to everything we're already doing in crypto. I think that's the future of crypto social

But why social graph w/o a focus on posting? People need to open their mind to social beyond twitter clones. Many other use cases:
- Web of trust
- Portable address book to make sending crypto more secure
- Context for who someone is and their relation to me
- Probabilistic proof of human
- And more! Whatever you want to do

The Onchain Profile Future
The screenshot below shows @VitalikButerin's ENS profile enhanced with the EFP social graph (he's a user). Everything there is onchain and open for all apps to use for free. Some apps use this, but most don't. We could have this in all crypto apps if we simply decided to.

WLFI integrates ENS + SIWE in its bridge

ENS = infrastructure

@ethereum | @ensdomains | @worldlibertyfi | @signinethereum

@0xngmi the creator of Sign in with Ethereum here are my thoughts

1) the company charged by ENS and EF with leading Sign in with Ethereum took the grant money and abandoned the project without even finalizing the EIP, which is why little happened with SIWE in the last few years (to their eternal shame). so a few months ago my new company @ethidorg took it over for free, got the EIP finalized, recreated all the brand assets, and have started getting integrations again --> @signinethereum

2) Login with Wallet is bland and lame, Sign in with Ethereum is an EIP auth standard that combines with ENS (for usernames and profiles) for a full auth+username+profile experience

3) "User forgets account" much less likely if they name their wallets with ENS. Also, SIWE is now been extended to have persisting sessions

4) "How to do i email them?" You can still require them to verify an email on the first login if you want

5) Much more work is needed for both SIWE development and promotion, but my company is now working on it 💪💪

Ethereum Follow Protocol (EFP) is an onchain social graph protocol for Ethereum accounts, designed to complement @ensdomains and @signinethereum, and is supported by the @ENS_DAO Service Provider Program
