Gasless Transactions

Zero gas fees for your users

Enable USDT and USDC payments without requiring users to hold native tokens for gas. EIP-3009 and ERC-4337 account abstraction make it possible across 19+ EVM chains.

Advantages

Benefits

Better User Experience

Users don't need ETH, MATIC, or other native tokens. They pay only in stablecoins.

Higher Conversion Rates

Remove the friction of acquiring gas tokens. Users can pay immediately with what they have.

Simplified Onboarding

New users can start transacting without understanding gas or bridging tokens.

Predictable Costs

Transaction fees are paid in stablecoins, making costs predictable regardless of network congestion.

Under the Hood

Technical Details

EIP-3009: Transfer With Authorization

Allows token transfers via signed messages. The user signs a permit, and a relayer submits the transaction, paying the gas on behalf of the user.

ERC-4337: Account Abstraction

Smart contract wallets that can pay gas in any token. Bundlers aggregate user operations and submit them to the network.

Paymaster Contracts

Sponsor gas fees for specific operations. The paymaster validates and pays for user operations that meet certain criteria.

Relayer Network

Decentralized relayers compete to submit transactions, ensuring reliability and competitive pricing.

Implementation

Code Example

Gasless USDT0 Transfer

import { createGaslessTransfer } from "@t402/wdk-gasless";

// User signs an EIP-3009 authorization (no gas needed)
const authorization = await createGaslessTransfer({
  token: "USDT0",
  from: userAddress,
  to: merchantAddress,
  amount: "10.00",
  network: "eip155:8453", // Base
  deadline: Math.floor(Date.now() / 1000) + 3600,
});

// Facilitator submits the transaction on-chain
const result = await facilitator.settle(authorization);
console.log("Transfer complete:", result.txHash);
