Gasless Applications

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:

Approach	Who Pays	Best For
Sponsored	You (developer)	Onboarding, promotions, premium features
Pay in Tokens	User (in ERC-20)	Users with stablecoins, no native tokens
Cross-Chain Gas	User (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

Choose Your Approach

Sponsored Gas
Pay in Tokens
Cross-Chain Gas

You pay for everything. Users never see or think about gas.Best for:

New user onboarding
Free trials and promotions
Premium/paid features
High-value conversions

const quote = await meeClient.getQuote({
  sponsorship: true,
  instructions: [...]
});

User pays, but in any token. No ETH needed.Best for:

DeFi users with stablecoins
Trading applications
Users who refuse to hold native tokens

const quote = await meeClient.getQuote({
  instructions: [...],
  feeToken: { address: USDC, chainId: 8453 }
});

Pay from any chain. Execute on Arbitrum, pay from Base.Best for:

Multi-chain apps
Users with fragmented balances
Bridging workflows

// Execute on Arbitrum, pay gas from Base
const quote = await meeClient.getQuote({
  instructions: [{
    chainId: 42161,  // Arbitrum
    calls: [...]
  }],
  feeToken: {
    address: USDC_BASE,
    chainId: 8453    // Pay from Base
  }
});

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.

Supported Tokens

Any ERC-20 with liquidity can be used for gas:

Category	Examples
Stablecoins	USDC, USDT, DAI, FRAX, LUSD
Wrapped	WETH, WBTC, wstETH
Yield	aUSDC, stETH, sDAI
