South Korea is tightening how money moves to offshore crypto platforms, after Bybit, MEXC and HTX had their apps pulled from the local Google Play store.

Under revised rules, exchanges can require proof of account ownership, the purpose of a transaction and the source of funds, and can delay or reject a transfer when that information is insufficient. Transfers of 10 million won (about $7,000) or more to overseas exchanges or self-hosted wallets will face enhanced suspicious-transaction monitoring.

The move tightens oversight of capital leaving regulated Korean venues for offshore platforms and personal wallets, extending Seoul's push to keep crypto flows inside supervised channels.
