Wallet achieves deadlock-free concurrent transfers through sorted lock acquisition (prevents cycles), two-tier locking (isolates balance vs transaction-list contention), and frozen checks inside the lock (eliminates TOCTOU between freeze and movement).
Three complementary locking disciplines compose into a deadlock-free, race-free concurrency model
