MEDIUM: CoinPay payment error handling silently swallows failures

[Inkcha]

Description

getCoinpayPayment() and createCoinpayPayment() in apps/web/lib/coinpay.ts silently catch all errors and return null/error objects, making payment failures invisible. If the CoinPay API is temporarily unreachable or returns an unexpected response, the error is swallowed without logging.

Location

apps/web/lib/coinpay.ts:L56, L64:

catch { return null; }

Impact

Silent payment failures — users may not receive their paid entitlements and nobody gets alerted. The payment status route depends on polling CoinPay, and if the poll silently fails, the user sees a perpetual "pending" state.

Suggested Fix

Add error logging before returning null:

catch (err) {
  console.error("[coinpay] failed to fetch payment:", (err as Error).message);
  return null;
}
