Details

I believe that 45JN3TRGHRCS4WYDGTKCYMMYN6Z2LXGMGNEFEJ5CM7BRCE5EK2FR27K4IA and MZO4RABK7T3ZV6N75Z4IVDTI56BPPLSKWBKUDIY7NJNO2PVKSTAP4IGNTA are addresses associated with the Canadian Exchange, NDAX.

Firstly, there are some txn notes which label 45JN as NDAX. These can be seen here: https://allo.info/tx/TF4LUAOM5SS3SN6TOVOZEVNAERYVAPSNT4WJZKBGZOJQK2PGAVTQ, https://allo.info/tx/GURY43PTTPKSU33HMYXQGYH3MCU5DKQT7SUXGUBOTZGCMJTZ2DQQ, and https://allo.info/tx/AZDFGZWM2AJWT3RCVELMBU2KSWJTNRB4PLNOUS7O3QYWKTNNAILA. Each recipient only transfers to 45JN, acting as a deposit address. Thus the notes indicating "ndax" should be applied to the 45JN address.

Also, the address activity mostly aligns with listing announcements. According to this post, NDAX announced that Algorand was available for trading on Dec. 25, 2021, https://www.reddit.com/r/NDAX/comments/roe8dy/new_coin_listings_merry_christmas_from_ndax/. The address activity begins shortly after the announcement on Dec. 31, 2021, https://allo.info/account/45JN3TRGHRCS4WYDGTKCYMMYN6Z2LXGMGNEFEJ5CM7BRCE5EK2FR27K4IA/txns?sorting=ROUND_ASC. Normally the account activity precedes the announcement, though it could be that NDAX didn't have any buys for the first 5 days. Regardless, the address start date is within a reasonable timeframe with the official announcements.

Additionally, it should be considered that MZO4 is an NDAX address along with 45JN. The 45JN address only has 3 outflow destinations, the vast majority of which goes to MZO4, https://flow.algo.surf/address/45JN3TRGHRCS4WYDGTKCYMMYN6Z2LXGMGNEFEJ5CM7BRCE5EK2FR27K4IA. The first outflow of the 45JN address was to fund MZO4, https://allo.info/account/45JN3TRGHRCS4WYDGTKCYMMYN6Z2LXGMGNEFEJ5CM7BRCE5EK2FR27K4IA/txns?sorting=ROUND_ASC. And the first inflow to MZO4 was from 45JN, https://allo.info/account/MZO4RABK7T3ZV6N75Z4IVDTI56BPPLSKWBKUDIY7NJNO2PVKSTAP4IGNTA/txns?sorting=ROUND_ASC. Additionally, MZO4, handles outflows to many addresses, but only has inflows from a handful of different addresses, https://flow.algo.surf/address/MZO4RABK7T3ZV6N75Z4IVDTI56BPPLSKWBKUDIY7NJNO2PVKSTAP4IGNTA. Thus, it looks like 45JN is an address for aggregating deposits, and MZO4 is used for handling withdrawals. They are complementary addresses.

Overall, both the 45JN and MZO4 addresses should be identified with the NDAX exchange, based on a handful of transaction notes identifying so, the address activity being roughly the same time as an official announcement and the funding flows which link the two addresses.
