Submit a toolWhat are Account Abstraction (ERC-4337) Bundlers?
Account Abstraction (ERC-4337) Bundlers are tools and services that facilitate the aggregation and submission of user operations to the Ethereum network under the ERC-4337 standard. These bundlers collect multiple user-initiated actions, package them into a single transaction, and submit it to the blockchain, enabling smart contract wallets to operate without requiring users to hold native ETH for gas fees. Tools in this category include bundler implementations, relayers, and infrastructure that support the ERC-4337 mempool and transaction flow.
The primary use cases for these bundlers are enabling flexible account management, gas fee abstraction, and enhanced user experience in decentralized applications. Target users include developers building smart contract wallets, dapps requiring meta-transactions, and projects aiming to implement advanced account features like session keys or paymasters. Key characteristics of these tools include support for user operation pooling, transaction bundling, and integration with the ERC-4337 EntryPoint contract.
This category is closely related to wallet solutions and meta-transaction relayers but focuses specifically on the bundling and submission layer defined by ERC-4337. Developers should look for tools in this category when implementing account abstraction features that require efficient transaction aggregation and gas fee management without modifying the Ethereum protocol itself.
