A Next-Generation Solution for ERC-4337

The Gelato Bundler is a versatile and production-ready solution for ERC-4337, supporting all major EVM networks and various paymaster models, including Verifying Paymasters and ERC20-based paymasters.

However, the key difference between Gelato Bundler and traditional bundlers is that it introduces an additional way to sponsor gas—via 1Balance.

Unlike other bundlers that rely solely on on-chain paymasters per network, Gelato Bundler allows gas sponsorship through a unified gas tank (1Balance) deployed on Polygon, making multi-chain gas sponsorship seamless. Read more about 1Balance .

Key Advantages

1. Universal Sponsorship & Payment Options

  • Compatible with Verifying Paymasters & ERC20-based Paymasters

  • Allows users to pay gas with ERC-20 tokens directly from their smart accounts

  • Supports self-custodial native gas payments

2. Precision & Efficiency

  • No overpayments – only the exact gas consumed is deducted

  • Eliminates the need for prefunding transactions

  • Allows predictable and efficient fee management

3. Instant Inclusion & MEV Protection

  • No bundling delays – transactions are processed individually

  • Flashbots integration provides protection against front-running on Ethereum

4. Unlimited Validation Logic

  • No opcode restrictions or gas limits

  • Supports advanced signature verification and authentication flows

5. Built on Existing Relay Infrastructure

  • Since Gelato Bundler is built on Gelato’s proven Relay infrastructure,

    • UserOp status can be easily checked

    • Debugging becomes more efficient using the Relay API

6. Production-Ready & Scalable

  • Trusted by leading Web3 projects

  • Designed to scale seamlessly with your dApp’s growth
