ZeroDev's ERC-7683 Integration: Faster, Cheaper Account Abstraction

ZeroDev is revolutionizing account abstraction with Across's ERC-7683 framework, delivering transactions that are up to 40% faster, 30% cheaper, and natively crosschain-compatible. ERC-7683 improves on ERC-4337 with customizabilty, shared relayer networks, and seamless interoperability across 16+ chains. The integration empowers developers to build smarter, faster, and more user-friendly dApps while maintaining full compatibility with existing standards. Explore the demo or docs to see it in action.

The future of account abstraction is here, and ZeroDev is building it with Across’ ERC-7683 framework. With transactions up to 40% faster, 30% cheaper, and crosschain compatible, ZeroDev’s innovative infrastructure shows potential for significant performance improvements for account abstraction technology.

Let’s explore how ZeroDev’s implementation of ERC-7683 enhances the account abstraction ecosystem.

Account abstraction simplifies blockchain transactions by making wallets programmable, flexible, and user-friendly. This innovation is changing how people interact with web3, especially across chains. As blockchain adoption grows and users increasingly operate across multiple chains, developers are looking for ways to optimize performance and reduce costs. ZeroDev and Across are working together to meet these emerging needs.

ERC-4337 has been instrumental in driving the first wave of account abstraction adoption. It introduced key innovations like bundlers for transaction batching and paymasters for gas sponsorship. As the ecosystem matures, developers are looking for ways to optimize performance and enhance crosschain capabilities.

However, the ERC-4337 framework has some limitations. For example, while pivotal for initial adoption, ERC-4337 prescribes a bundling mechanism and public mempool. While this design enables decentralization, it introduces challenges in achieving low latency and customizing transaction fields.

ERC-7683 addresses these gaps by offering developers the ability to fine-tune transactions with customizable fields, optimizing for specific use cases. This flexibility allows ERC-7683 to achieve faster, more efficient processing without sacrificing security.

Building on this foundation, ZeroDev has collaborated with Across to integrate ERC-7683 in their new account abstraction infrastructure, UltraRelay. This new infrastructure enables faster, cheaper, and crosschain-compatible transactions for smart accounts without compromising on security. This integration delivers significant performance improvements:

These performance improvements open up new possibilities for builders looking to create seamless user experiences across multiple chains.

ERC-7683 is a new standard for crosschain infrastructure co-developed by Across and Uniswap Labs. It promotes the use of Intents in a universal, accessible, and scalable manner, providing a framework that anyone can use.

Shared relayer networks are a key component of ERC-7683. They consist of third-party solvers who execute crosschain Intents for end-users "under the hood"—a modern take on account abstraction designed with performance and crosschain interoperability in mind.

ZeroDev leverages ERC-7683 relayers to power UltraRelayer, their new account abstraction infrastructure. By introducing a few trust assumptions and integrating native crosschain functionality, their approach optimizes efficiency and expands interoperability across multiple chains.

Here’s how it works:

Relayers optimize trust assumptions. By reducing unnecessary interactions, transactions save gas and time without compromising security. It’s like cutting out the middleman for smarter execution.

ERC-7683 balances decentralization with pragmatic optimizations to improve efficiency without sacrificing user trust. While ERC-4337 uses a public mempool where user operations are visible to all paymasters, ERC-7683 handles order generation through a private API (e.g. the Across API). This approach helps prevent potential spam attacks while maintaining efficient transaction processing.

This is where Across’s magic shines. By leveraging Across’s crosschain engine, ERC-7683 relayers power seamless interactions across 16 chains (and growing!). Users can move assets and execute transactions across chains without manual bridging or extra steps. No nonsense. No headache. Just smart, chain-abstracted accounts that work wherever you need them. This is native crosschain at its best.

But don’t just take our word for it. Check out the ZeroDev’s UltraRelayer live demo to see the performance improvements yourself.

With ZeroDev, we are laying the foundation for the future of account abstraction—and we're doing it in a way that is compatible with the current ecosystem:

ZeroDev is using Across-powered ERC-7683 relayers to push the boundaries of account abstraction. Faster transactions. Lower costs. True crosschain capabilities. Whether you’re a developer building the next big dApp or a user wanting a seamless web3 experience, ERC-7683 makes it all possible.
