Very cool to see the ecosystem of interoperable modules growing! 👏👏👏
Introducing Modular Wallets, a new, customizable infrastructure that gives developers greater control over their app experience—available now for @arbitrum and @0xPolygon PoS.
Programmable Wallets just got more programmable.
Unlike User- and Developer-Controlled Wallets that offer fully managed wallet infrastructure, Modular Wallets allows developers to customize their app development in an à la carte way.
Key features:
✅ Flexible key management for customizable security
✅ Indexing service for efficient data retrieval
✅ Passkey support for a seamless user experience
At Circle, we believe in the power of openness and interoperability.
Last year, we announced our co-authorship of ERC-6900 with industry leaders such as @Alchemy, @TrustWallet, @Quantstamp and @ethereumfndn. Modular Wallets allows developers to participate in, grow with, and benefit from this emerging ecosystem.

We're proud to announce Senior Auditing Engineer, Ruben Koch (@0xrubes) is co-authoring the ERC-6900 (@erc6900) standard alongside others from @ethereum, @AlchemyPlatform & @BuildOnCircle!
A thread 🧵
Fun personal project over the weekend. Learned lots about bitcoin, ordinal theory, and runes. Hope y'all had a nice halvening!

1/ Congratulations to Daniel Lim, @hwgcircle, and @BostonXiaoyu from @Circle’s engineering team on contributing to @erc6900 as co-authors alongside @AlchemyPlatform and @yoavw from the @ethereum Foundation!
This is an important problem. Let's come to consensus on a common way for smart contract accounts to compose and validate transparent and secure signatures. Join the discussion (TG link in thread below)
There's a problem with ERC1271 signatures for smart contract accounts.
Without a good ERC1271 implementation for smart accounts, it will be difficult for dapps to show users what they’re signing.
We’re launching a working group for this problem. TG link below ⬇️

We’ve noticed there have been many misconceptions around modular account standards, and wanted to highlight some of the latest thinking there: mirror.xyz/probablynoam.eth/….

Today we’re excited to release Embedded Accounts in open beta.
Onboard users to simple, non-custodial web3 accounts that make the "wallet" invisible.
Plug and play with web2 login, passkeys, email recovery, gas abstraction, batch transactions, session keys and more.

Meet Modular Account 👋
The most performant, enterprise-grade smart account implementation that is fully compliant with ERC-4337 and ERC-6900.
Deployed on Ethereum, Arbitrum, Optimism, Polygon, and Base.

0. Denominate in ETH; USD is noise.
1. Go long on the base layer. ETH, staking, derivs. By extension, L2s and bridges.
2. Be wary of the app layer. I don't have an edge there, and you probably don't either. That's ok.
3. Governance value is on a glide path towards 0 over time.
