Allow users to pay gas fees using ERC-20 tokens like USDC, USDT, or other supported tokens instead of native ETH. This significantly improves user experience by removing the need to hold native tokens.

​
Payment Approaches

There are two ways to enable ERC-20 gas payments with the Gelato Bundler:

Direct Payment (Gelato SDK)

Simplest integration using Gelato’s built-in token payment

On-Chain Paymaster

Use third-party paymasters like Pimlico for token payments

​
When to Use Each Approach

Use the Gelato Gasless SDK when you want:
  • Fastest integration - Single SDK handles everything
  • Automatic token handling - No manual paymaster setup required
  • Gelato-optimized gas costs - Built-in fee optimization
  • Simple API - Just specify payment: token(tokenAddress)

​
On-Chain Paymaster

Use an on-chain paymaster when you need:
  • Custom paymaster logic - Specific business rules for gas sponsorship
  • Existing paymaster integration - Already using Pimlico, Alchemy, or other providers
