Gas fees are the #1 reason users abandon transactions. They don’t have ETH or don’t understand gas. Gasless apps eliminate this entirely.
MEE Replaces Bundlers and Paymasters: Traditional ERC-4337 implementations require configuring separate bundlers (for transaction submission) and paymasters (for gas sponsorship). Biconomy’s MEE (Modular Execution Environment) supersedes both, providing unified gas sponsorship, transaction bundling, and cross-chain orchestration in a single, simpler interface.

The Problem

72% Drop-Off

Users abandon when asked for gas

Wrong Token

Users have USDC but need ETH

Surprise Costs

Unexpected fees kill trust

Complex UX

Gas estimation confuses users

The Solution

Biconomy offers three approaches to eliminate gas friction:
ApproachWho PaysBest For
SponsoredYou (developer)Onboarding, promotions, premium features
Pay in TokensUser (in ERC-20)Users with stablecoins, no native tokens
Cross-Chain GasUser (from any chain)Users with funds on different chains

Who Should Go Gasless?

Consumer Apps

Users are crypto-novice
Onboarding friction kills growth
Small transaction values (gas > value feels wrong)
Examples: Games, social apps, NFT mints, loyalty programs

DeFi Applications

Multi-step transactions (approve + swap + stake)
Cross-chain operations
Users already hold ERC-20 tokens
Examples: DEX aggregators, yield optimizers, portfolio managers

Enterprise & B2B

End users shouldn’t think about blockchain
Predictable costs (you control spending)
White-label solutions
Examples: Payment processors, supply chain, tokenized assets

How It Works

User Action

Your App calls Biconomy MEE API/SDK

Quote returned with fee (if not sponsored)

User signs message (not transaction)

MEE handles everything:
  - Bundles transactions (replaces bundlers)
  - Sponsors or deducts gas (replaces paymasters)
  - Orchestrates cross-chain if needed

Transaction confirmed
Users sign messages, not transactions. This means no wallet pop-ups asking about gas, no “speed up” or “cancel” options—just a clean signature request.
No More Bundler/Paymaster Configuration: Unlike traditional ERC-4337 setups where you configure bundler URLs and paymaster URLs separately, MEE provides all this functionality through a single API key and unified interface.
