+# Scanner: TON processTransfer doesn't verify JettonMasterAddress vs intent.TokenAddress
+
+**Severity:** low
+**Domain:** Scanner
+**Labels:** bug, scanner, token-verification
+
+## Description
+
+`scanner/ton_chain.go:203` processes TON jetton transfers without explicitly verifying that `tr.JettonMasterAddress` equals `intent.TokenAddress`. It trusts the API filtering to return only the correct jetton, but a compromised API or a jetton with the same wallet address could pass silently.
+
+## Options
+
+1. Assert `tr.JettonMasterAddress === intent.TokenAddress` before confirming.
+2. Trust API filtering but log mismatches.
+3. Verify and reject on mismatch.
+
+## Recommendation
+
+Add an explicit equality check and reject mismatches rather than trusting API filtering.
