OKX, formerly OKEx, is a cryptocurrency exchange that in November 2022 published a list of its bitcoin reserve wallet addresses as part of an industry-wide proof-of-reserves push. Those disclosed addresses were captured in the GraphSense TagPacks and are corroborated by independent rich-list trackers. OKX is a terminal hub in the transaction graph.
What is and is not established. The first six addresses trace to OKX's own November 2022 public disclosure via GraphSense (source field points at OKX's own post). 3MgEAFWu1HKSnZ5ZsC8qf61ZW18xrP5pgd is a third-party clustering label (BitInfoCharts "OKEx", CoinCarp "OKX") and is NOT in the disclosed set. The disclosure is dated November 2022 and OKX has certainly rotated and added addresses since. Two entries in the fetched OKX tagpack rendered as 33-character strings, which is shorter than any valid Bitcoin address - almost certainly a transcription loss in the fetch pipeline rather than real addresses - so they were dropped rather than repaired. I verified 16rF2zwSJ9goQ9fZfYoti5LsUqqegb5RnA on-chain (36 funding transactions, zero spends). This is a labelled sample of a much larger cluster.
