Trade Failure Actions - DZap

When trade() fails, check result.action and handle accordingly:

Action	Meaning	Suggested handling
`TRY_ANOTHER_ROUTE`	Recommended route failed	Rebuild `data` with `protocol: bestReturnSource` from the quote and call `trade()` again.
`INCREASE_SLIPPAGE`	Slippage too low	Ask user to increase slippage and retry.
`INCREASE_ALLOWANCE`	Allowance insufficient	Re-run allowance/approval flow and retry.

Example:

if (result.status !== TxnStatus.success && result.action === "TRY_ANOTHER_ROUTE") {
  const fallbackData = request.data.map((d, i) => {
    const pairKey = Object.keys(quotes)[i];
    const fallbackSource = quotes[pairKey]?.bestReturnSource;
    return fallbackSource ? { ...d, protocol: fallbackSource } : d;
  });
  result = await dZap.trade({ request: { ...request, data: fallbackData }, signer });
}
