Wallets have become the starting point for almost every interaction in Web3: sending tokens, collecting NFTs, exploring new dApps, or making a first DeFi trade. As the Ethereum ecosystem grows, improving wallet experience and security has become increasingly important. Most users still rely on EOAs (external or key-based accounts), which work well but are limited compared to the functionality required by modern Web3 applications.
EIP-7702 solves this problem by improving the capabilities of EOAs without requiring users to switch to another wallet type. It allows an EOA to temporarily act as a smart account during a transaction, giving it access to more flexible and secure behavior only when needed.
To help developers upgrade EOA wallets in this way, the ecosystem needs more than the proposition itself. This requires a EIP-7702 Infrastructure which enables secure transaction flows and supports Ethereum’s decentralized design.
The EIP-7702 infrastructure is particularly important to service providers because it enables the 99.9% availability required by SLAs for mature Web3 projects and enterprise customers. Built on decentralized foundationsit avoids single points of failure and provides the reliability required by large-scale applications.
Why EIP-7702 improves key-based wallets
EOA (key-based wallets) are entirely dependent on a private key. This simple design works, but it doesn’t support features that can make the Web3 experience more like Web2: smooth, intuitive, and more secure.
EIP-7702 changes this by allowing EOAs to unlock smart account features only when needed.
As a result, key-based wallets can offer:
- Gasless Transactionswhere users do not need native tokens to pay for gas.
- One-Click Actionsallowing you to perform multiple steps in a single interaction.
- Spending limitsadding more control and security to transactions.
- Session keysallowing temporary permissions for smoother use of dApp.
- Better wallet protection and more secure application interactions.
Together, these upgrades make Web3 experiences more predictable and user-friendly.
Why EIP-7702 infrastructure is important for developers
Although EIP-7702 defines how this new behavior works, its true adoption depends on the infrastructure that powers it. Strong EIP-7702 infrastructure makes upgrading convenient for builders, wallets and users.
This is why the The Ethereum Foundation awarded a grant to the Etherspot team to build and deliver reliable EIP-7702 development infrastructure. It is online today, open source and free.
This infrastructure helps in several ways:
- It allows EOAs to use account abstraction featuressuch as gasless transactions, one-click actions, spending caps or session keys, without requiring user migration.
- He improves decentralization through the ERC-4337 shared memory poolwhich removes single points of failure and improves reliability.
- He offers a censorship-resistant alternative to authorized torchbearers.
- He integrates easily with standard Web3 libraries and existing wallet stacks, so developers don’t need to rebuild everything from scratch.
Without this infrastructure layer, each portfolio team would have to build these components themselves, slowing adoption and increasing risk. The infrastructure ensures that EIP-7702 operates securely, consistently, and at scale.
Looking Ahead: A Better Portfolio Experience for Everyone
EIP-7702 improves EOA without changing how users interact with their wallets. It adds better security, flexibility, and more modern behavior, while retaining the familiar key-based model.
As adoption increases, EIP-7702 Development Infrastructure will be key to bringing these improvements into real wallets and dApps. With the right support, EIP-7702 can help make Web3 smoother, more secure, and easier to use.
