Notes and record state

Record note
Japan FSA records list OKCoin Japan K.K. as crypto-asset exchange operator Kanto Finance Bureau No.00020 with registration date 2020-03-30 and LSK among handled assets. Current first-party OKJ/OKCoin Japan surfaces expose active trading and related services. HEI keeps this as a distinct Japanese regulated exchange entity rather than absorbing it into global OKX. Launch date remains null because the reviewed sources establish registration and current operation, not a single verified public launch date.
