​
Chain Abstraction Token Swapping

Trails enables seamless token swapping across multiple blockchain networks, allowing users to exchange tokens without manually bridging assets or dealing with multiple DEXs.

​
Enhanced Swapping Experience

Traditional cross-chain swapping requires users to:
  • Approve any ERC20 tokens
  • Bridge tokens to the target chain
  • Find and interact with DEXs on multiple networks
  • Pay gas fees on each chain
  • Wait for bridge confirmations
We optimize the UX flow, integrated as a simple widget for your application to enable swaps across multiple liquidity sources with any token in the user’s wallet. All interactions executed in a single confirmation for the user. Notably, this works across any wallet or application, ERC-7702 is not required for batching transactions.

​
Examples

Modes: pay = exact destination amount (exact-output); fund = deposit/top-up where the user chooses how much to send. See Pay and Fund.

Simple Cross-Chain Token Swap

Leveraging the Trails widget for a cross-chain swap that pays 0.1 USDC on Base: 
import { TrailsWidget } from '0xtrails/widget'

export const CrossChainSwap = () => {
  return (
    <TrailsWidget
      toAddress="0x12c4A952b46bEcaD0663f76357d3776ba11566E1" // Recipients's wallet address
      toAmount="0.1"
      toChainId={8453} // Base
      toToken="USDC"
      theme="auto"
    >
      <button className="custom-button-styles">
        Swap to USDC on Base
      </button>
    </TrailsWidget>
  )
}
Stablecoins are a great option to move between chains or execute swaps since they typically have high liquidity and very low slippage so are great for large values. We are compatible with nearly any stablecoin with onchain liquidity to tap into.

Stablecoin Cross-Chain Swapping

import { TrailsWidget } from '0xtrails/widget'

export const StablecoinSwap = () => {
  return (
    <TrailsWidget
      toAddress="0x..." // Recipient address
      toAmount="1000" // 1000 USDT
      toChainId={42161} // Arbitrum
      toToken="USDT"
      theme="auto"
    >
      <div className="swap-button">
        Swap to USDT on Arbitrum
      </div>
    </TrailsWidget>
  )
}
