Longer pieces on specific OKX questions: whether the exchange is safe, what can go wrong with perpetual futures, why an order or a transfer didn't do what you expected, and how fee tiers work. For step-by-step basics, start with the guides to deposits, your first trade and account security.
How OKX's proof of reserves works and how to check your own balance in it, the OKX licences you can find in a regulator's own register, and the October 2020 withdrawal suspension. Plus a 7-item check you can run on any exchange.
Proof of reserves only shows on-chain coins at one snapshot. How Merkle sum trees and zk proofs work, how to check your balance, and six things to read first.
What leverage does to a position, how funding is charged, when OKX liquidates, how perpetuals differ from expiry futures, and the order settings that matter on a closing order: stop-market vs stop-limit, reduce-only and trigger prices.
What spot mode, futures mode and multi-currency margin can each trade, where to switch in the app and on the web, and whether cross margin puts one currency or your whole account on the line. Points where OKX's own help pages disagree are flagged.
OKX Post only keeps an order maker-only and cancels it if it would fill at once. Maker vs taker fees, what triggers a cancel, and Post only vs FOK vs IOC.
BTC, ETH, TRC20, Arbitrum, Solana and Polygon compared on OKX's withdrawal fee, with a "which network" decision tree, what to do when a withdrawal stalls or fails, and how to send coins that need a memo or destination tag.
OKX does not currently accept USDT deposits on BNB Smart Chain (BEP20). To withdraw USDT from Binance, choose a network listed on OKX's deposit page, such as TRC20.
