Transaktions- & Wallet-Infrastruktur

Etherspot is a multi-chain Account & Chain Abstraction development infrastructure that provides solutions for dApps, wallets, games, operating EVM-compatible rollups, or L1/L2 chains to deliver seamless cross-chain Web3 user experience by removing usability pain points. In addition to providing Account and Chain Abstraction features, Etherspot helps developers make their projects compatible with the latest Ethereum standards, including ERC-4337, ERC-7579, and EIP-7702, by offering a wide range of cutting-edge services such as Bundler and Paymaster services, APIs, and more. Etherspot is pioneering the ERC-4337 shared mempool innovation, which is already live on Optimism.

With this setup, ecosystems can deploy tailor-made 4337 chain abstraction infrastructure. They become Liquidity Providers (LPs) for their users, sharing with them the value that would otherwise have been captured by solvers/fillers.

Rundler (Rust Bundler) is an ERC-4337 bundler implementation written in Rust. Rundler is designed to achieve high-performance and high-reliability in cloud deployments via a modular architecture. Currently, both Alchemy and Coinbase’s Base team use Rundler. It powers >70% of UOs in the Ethereum ecosystem and a vast majority of UOs in the Superchain. Rundler is OSS licensed with GPL. Rundler powers the ERC-4337 ecosystem with an implementation that users can rely on to scale reliably. Rundler open source code repo has 300+ stars, more than 50 forks. Our goals with Rundler: ERC-4337 Specification Compliance: Rundler strives to implement the full ERC-4337 specification and to maintain support as the specification changes and new onchain components are released. This includes new Entry Point contract support, support for the upcoming P2P mempool specification, support for alternative mempools, and more. Best-in-class Performance and Reliability: Rundler strives to power the most demanding workloads in cloud environments. Rust was chosen for its high performance and memory safety. Rundler's modular architecture lets providers choose to run the stateless components (RPC, builder) in a fully horizontally scalable manner connecting to the stateful components (mempool, p2p, event cache) via the network. Rundler's bundle builder is designed to be able to support the full gas throughput of the network it's building for. Extensibility/Chain Support: ERC-4337 is designed to support any EVM chain. However, different EVM supporting networks have different rules around how to support things like gas usage, gas fees, precompiles, etc. Rundler is designed to be extensible and easily adapted to support any EVM chain. Modularity: Rundler is written in a modular manner, allowing its components to be run as a single integrated binary, or as a distributed system. Rundler also strives for its individual crates to be used to support future ERC-4337 tooling. In RPGF Round 3, Alchemy was awarded a total of 74,534 $OP across Rundler, Light Account, ERC-6900, aa-sdk, and various informational pieces put out to the public domain to further adoption of smart accounts in the Superchain.
