Ethereum’s Pectra Upgrade: What It Means for Reown and Why Your Onchain UX Just Got Better
The Ethereum Pectra upgrade is one of the most significant shifts in the network’s history. It introduces native account abstraction (EIP-7702), enhances data storage with more blobs, and enhance data storage with more blobs, reducing layer 2 costs, all while reshaping how users and apps interact onchain.
At Reown, we don’t just support these changes. We helped shape them. Our SDKs already support the standards that Pectra makes possible. That means you can deliver next-generation wallet and app experiences today, without rewrites or delays.
What Is the Pectra Upgrade?
Ethereum’s Pectra hard fork brings critical infrastructure improvements that make the onchain experience faster, cheaper, and more intuitive. The most transformative piece is EIP-7702, which allows externally owned accounts (EOAs) to act like smart accounts, without requiring users to switch wallets or migrate funds.
This upgrade fundamentally changes what’s possible for wallets, apps, and the users they serve.
How Account Abstraction (EIP-7702) Transforms Onchain UX for Apps and Wallets
Account abstraction with EIP-7702 is a major Ethereum upgrade that transforms onchain UX by bringing advanced wallet features, like gasless transactions, smart sessions, and passkey login, to every account, not just contract wallets.
With Pectra, developers can now bundle swaps, approvals, and chain switching into one smooth user flow, sponsor gas fees with paymasters, and enable secure automation for subscriptions or delegated access. Users benefit from faster, more intuitive crypto wallet UX, with recovery options like passkeys, email, or social login.
For app and wallet builders, this unlocks Web2-grade experiences without compromising decentralization. With wallet_sendCalls and other standards now live, account abstraction makes Ethereum apps easier to use, more scalable, and ready for mainstream adoption.
Reown Is Already Aligned With Pectra
We’ve been building toward this future for over a year. That’s why Reown SDKs already support the key elements of the Pectra upgrade:
AppKit
- Gasless by design: Built-in support for paymasters
- Smart sessions: Enable subscriptions, delegated signing, and more
- Developer-friendly: All features work out of the box for smart accounts, and now for any upgraded EOA
WalletKit
- One-step UX: Bundle transactions for smoother flows
- Chain abstraction simplified: Let you users pay with any token on any network.
- Premium monetization: Enable gas sponsorship as a paid feature, with minimal overhead
These aren’t concepts. They’re live, tested, and in production. Reown helps builders create wallet and app experiences that feel intuitive, no matter how complex the logic under the hood.
What Builders Should Know
If you’re using Reown’s SDKs, you’re already Pectra-ready. Still, to take full advantage of the upgrade, there are a few best practices:
- Use the latest version of AppKit to enable features like wallet_sendCalls (EIP-5792), smart sessions, and paymasters, making it easier to deliver seamless onchain flows in your app.
- If you're a wallet developer, make sure you're using the latest WalletKit and have implemented EIP-5792 correctly. It’s essential for supporting modern onchain UX, including batched calls, delegated sessions, and sponsored transactions.
- Upgrade your signer to match the 7702 spec to unlock native account abstraction
- Bundle flows wherever possible: approvals, swaps, logins, combine them
- Sponsor gas strategically, or let users pay with any ERC-20 token
These small adjustments can unlock major UX gains.
What This Upgrade Means for Your Business and Operations
The Pectra upgrade isn’t just technical, it’s strategic.
Apps and wallets can now reduce drop-off points in onboarding, conversion, and transaction flows. Lower L2 fees mean every interaction becomes cheaper. Bundled flows and sponsored gas lead to higher completion rates. Social recovery and familiar login methods improve retention and user trust.
For businesses, this translates to:
- Faster user acquisition with simplified sign-in and transaction flows
- Higher retention due to smoother, Web2-like UX
- New monetization paths via gas sponsorship and smart session-based services
- Reduced support costs thanks to clearer flows and fewer failed transactions
In short, better UX means better business outcomes. And with Reown, it’s already possible to deliver.
Why Reown Is Ahead of the Curve
We’ve tested the upgrade across our SDKs and infrastructure. From transaction bundling to smart sessions, Reown already delivers what Pectra enables.
- AppKit and WalletKit support native account abstraction and EIP-5792
- Paymasters, smart sessions, and sponsored gas are live
- No breaking changes, just new capabilities waiting to be unlocked
If you’re building with Reown, you don’t need to retrofit or wait. You’re already ahead.
