Enable gasless execution by providing a paymaster per-chain or using Sequence gasless transactions and setting the gasless flag on the widget.

​
Example: Gasless transactions using 4337 paymaster:

<TrailsWidget
  gasless={true}
  paymasterUrls={[
    { chainId: 8453, url: 'https://paymaster.example.com' },
    // { chainId: 42161, url: 'https://...' },
  ]}
  toAddress="0x1234567890123456789012345678901234567890"
  toAmount="0.1"
  toChainId={8453}
  toToken="USDC"
/>
The paymaster URLs must be 4337-compatible bundler/paymaster URLs for gasless transactions, such as Alchemy, Thirdweb, Pimlico, ZeroDev, etc. Set different URLs for different chains.

​
Example: Gasless transactions using Sequence:

<TrailsWidget
  gasless={true}
  appId="your-sequence-project-access-key"
  toAddress="0x1234567890123456789012345678901234567890"
  toAmount="0.1"
  toChainId={8453}
  toToken="0xA0b86a33E6417aB32db7ca5cC1F4a7cE28A3b7B7"
/>
