Account Abstraction

ERC-4337 Compatible Bundler & Paymaster

Overview

Gelato Bundler is a robust, production-ready solution for ERC-4337 that delivers seamless support across all major EVM networks. Rather than relying solely on on-chain paymasters like traditional bundlers, it utilizes 1Balance for gas sponsorship—a unified gas pool deployed on Polygon. This innovative feature provides effortless multi-chain gas sponsorship, making it an ideal choice for developers who need a flexible bundling solution. Read more about Gelato Bundler .

Limitations of Externally Owned Accounts (EOAs)

Ethereum users rely on Externally Owned Accounts (EOAs), which are controlled by private keys. While functional, EOAs have major limitations:

Security Risks – Losing a private key means losing access to funds permanently. A compromised key gives attackers full control.
Rigid and Manual Transactions – Users must manually sign every transaction, with no built-in automation or recovery options.
Gas Payment Restrictions – EOAs must always hold ETH for gas fees and cannot use ERC-20 tokens to pay for transactions.

Smart Wallets

Smart wallets, or contract accounts, are managed by smart contracts instead of private keys. They offer better security, automation, and flexibility, overcoming EOA limitations.

Why Smart Wallets?

Enhanced Security – Supports social logins, biometrics, session keys, and custom recovery methods.
Programmability – Can define custom rules and upgrade over time.
More Efficient Transactions – Allows batching multiple actions into one, reducing costs and complexity.
Gasless Transactions – Users can sponsor gas fees or pay with ERC-20 tokens instead of ETH.
Faster Execution – Supports parallel transaction processing for better efficiency.

How ERC-4337 Enables Smart Wallets

ERC-4337 enables account abstraction without modifying Ethereum’s core protocol. It allows smart wallets to operate on top of existing infrastructure, making advanced features available without disrupting the network.

Smart wallets provide a more secure, flexible, and user-friendly way to interact with Ethereum, paving the way for mainstream Web3 adoption.
