Overview

Trails supports paying gas fees in any permit-compatible (EIP-2612) token, including popular stablecoins like USDC and USDT. This removes the friction of needing native tokens on each chain.

​
Why This Matters

Common problems this solves:
  • New chain onboarding: Users bridge to a new chain but have no native tokens for gas
  • Stablecoin-first users: Users who hold primarily stablecoins don’t need to manage gas tokens
  • Simplified UX: One token type for both payment and gas fees

​
How It Works

  1. User initiates a transaction in the Trails widget
  2. By default, native gas token is shown as the fee option
  3. User can select alternative fee tokens (USDC, USDT, etc.)
  4. First time: User signs an EIP-2612 permit (gasless signature)
  5. Subsequent transactions: Single confirmation only

​
Supported Fee Tokens

Any token implementing EIP-2612 (permit) can be used as a fee token. See the API Integration Guide for the complete permit flow implementation at an API level.

​
Widget Behavior

In the Trails widget, alternative fee tokens are automatically presented to users when available. No additional configuration is required—the widget handles permit signatures and fee selection automatically.
