TLDREIP-7702, introduced with the Ethereum Pectra upgrade, allows EOAs to temporarily behave like smart accounts, unlocking Account Abstraction features without address migration. To ensure this new model remains decentralized and censorship-resistant, open infrastructure for submitting and processing UserOperations is essential. Backed by an Ethereum Foundation grant, the Etherspot team built a public EIP-7702 infrastructure integrated with the Shared Mempool, enabling reliable execution across multiple bundlers and networks. This infrastructure helps wallets adopt EIP-7702 safely, at scale, and without relying on permissioned relayers.via the TL;DR App

EIP-7702, introduced with the Ethereum Pectra upgrade, represents a major turning point for the EVM ecosystem. It lets Externally Owned Accounts (EOAs) operate as smart contract accounts for a limited time. This brings Account Abstraction (AA) features, such as advanced transaction logic and flexible gas payments, to existing EOA addresses.

Why EIP-7702 Infrastructure Matters

EIP-7702 introduces a new “setCode” transaction type (0x04) that temporarily equips EOAs with powerful smart account functionality. However, without an open and reliable infrastructure to handle UserOperation (UserOp) submissions, adoption of 7702 could become fragmented, while at the same time, private relayers introduce a risk of centralization.

To prevent this, the Ethereum Foundation awarded a grant to the Etherspot team to build and maintain an open-source, freely accessible, and censorship-resistant UserOp mempool nodes. This public EIP-7702 infrastructure aims to strengthen decentralization and censorship resistance while giving developers a transparent and reliable alternative to permissioned relayers. It also adds redundancy to the current bundler ecosystem, as UserOps from both ERC-4337 and EIP-7702 are shared across multiple bundlers through the Shared Mempool.

🚀 The free, censorship-resistant EIP-7702 infrastructure is now LIVE on Ethereum, Optimism, Arbitrum, Base, Unichain, and World Chain, and open for developers to test and integrate. Read the developer documentation to learn more!

Projects That Can Benefit from the EIP-7702 Infrastructure

Key-based Wallets

EOA (key-based) Wallets can now provide Account Abstraction compatibility to their existing users without requiring address changes.

With the freely accessible EIP-7702 infrastructure, wallet teams can:

  • Introduce batched transactions for improved UX.
  • Offer sponsored or gasless operations.
  • Add spending caps, session keys, or sub-accounts for greater security.
  • Seamlessly transition users toward full smart account functionality without requiring address migration.

These features empower wallets to evolve without affecting existing users. 🛠️ Wallet developers can easily integrate the EIP-7702 infrastructure using the developer docs. At the same time, by integrating the EIP-7702 infrastructure, EOA wallet teams can leverage existing ERC-4337 smart contract wallets with a wide range of proven, battle-tested implementations.

Account Abstraction Service Providers

Bundler providers can also benefit from the EIP-7702 infrastructure, as any bundler connected to the Shared Mempool can process 7702 UserOps. Additionally, it unifies Account Abstraction across ERC-4337 and EIP-7702, and allows bundlers to contribute to the censorship resistance of the Ethereum ecosystem. To join the Shared Mempool, reach out to the Etherspot team on Discord.

Decentralized Applications (dApps)

dApps that handle user transactions, such as DeFi platforms, NFT marketplaces, or on-chain games, can also benefit from wallets adopting EIP-7702. With standards like EIP-5792, they can quickly detect a wallet’s capabilities and enable features like transaction batching or gasless interactions, improving the overall user experience.

While EIP-7702 makes these capabilities technically possible, the EIP-7702 infrastructure ensures that UserOps from such dApps can be processed reliably across networks through the Shared Mempool.

What Makes the EIP-7702 Infra Developer-Friendly

For wallet developers, the EIP-7702 infrastructure offers:

  • Free access for all projects and individual builders (within fair-use limits).
  • Seamless integration. Developers can easily plug into their existing stack with standard Web3 libraries.
  • Optimized performance thanks to native tracer support for faster transaction execution.
  • Full compatibility with the latest EntryPoint version.
  • Always-on reliability backed by 24/7 developer support.

Currently supported networks: Ethereum, Optimism, Arbitrum, Base, Unichain, and World Chain.

Upcoming integrations: Linea.
