**Error handling**: If `/calldata` returns an error or fails, skip EIP-681 link generation and show only the route summary with a clear error note. Do **not** fall back to the old web deep link — notify the user that link generation failed and they should retry.

🔗 Transaction (EIP-681):
ethereum:0x5efc784D444126ECc05f22c49FF3FBD7D9F4868a@56?value=0x00&data=0x9aa90356...

📱 Binance Wallet: Import this EIP-681 URI into the Binance App → Web3 Wallet to sign the transaction.

🔗 Open in Trust Wallet:
https://link.trustwallet.com/send?asset=c20000714&address=0x5efc784D444126ECc05f22c49FF3FBD7D9F4868a&amount=0.28&data=0x9aa90356...

(Tapping this link opens Trust Wallet's native transaction signing flow.)

For all other non-headless channels (`pancakeswap`, `binance-wallet`), display the EIP-681 URL prominently — most wallets and QR code scanners can parse it directly. Optionally attempt to open it:

```bash

If the open command fails or is unavailable (headless environment), display the URL prominently for copy-paste.
