Understanding OKX's "T+N" Security Mechanism for Crypto Transactions
OKX (formerly OKEx) implements a robust "T+N" security protocol to enhance safety in C2C cryptocurrency transactions. This protection mechanism requires purchased assets to remain locked for "T+N" days (where T represents the transaction day and N varies per platform settings) before becoming eligible for withdrawal or resale via C2C trading.
Key Benefits of "T+N" Protection:
- Prevents fraudulent "hit-and-run" trading schemes
- Gives users time to verify transaction legitimacy
- Reduces risks associated with instant withdrawals after purchase
Step-by-Step Guide to Checking Withdrawal Timelines
