⚠️ Potential issue | 🔴 Critical

🧩 Analysis chain

Reset paymentId when address/currency/randomization inputs change to avoid stale IDs

Otherwise an ID tied to a previous address or unit policy may be reused.

   const [paymentId, setPaymentId] = useState<string | undefined>(undefined);
+  useEffect(() => {
+    setPaymentId(undefined);
+  }, [to, currency, randomSatoshis]);

If the server binds paymentId to the original amount as well, also include amount in the dependency list. Please confirm backend semantics.

Reset paymentId when address, currency, amount, or randomization inputs change to prevent reuse of stale IDs

Without resetting paymentId when these inputs change, the component can reuse IDs tied to previous addresses, amounts, or unit policies, causing validation mismatches.

   const [paymentId, setPaymentId] = useState<string | undefined>(undefined);
+  useEffect(() => {
+    setPaymentId(undefined);
+  }, [to, currency, amount, randomSatoshis]);

The backend's createPayment API endpoint receives both amount and address and generates an ID bound to those values (per react/lib/util/api-client.ts lines 98–99). Therefore, amount must be included in the dependency list alongside to, currency, and randomSatoshis.

🤖 Prompt for AI Agents 
In react/lib/components/PayButton/PayButton.tsx around lines 115 to 121, the
component fails to reset paymentId when key inputs change which can cause reuse
of stale IDs; update the effect/logic that computes addressType and paymentId so
that it includes amount (and already-present dependencies to, currency,
randomSatoshis) in its dependency list and call setPaymentId(undefined) whenever
any of those change, ensuring a new ID is requested for the new
address/amount/unit policy.

priceRef.current = price;
}, [price]);
