The short lesson
- Explorers show single transactions, addresses and contracts.
- Dashboards sum many transactions: flows into exchanges, holder counts, fees.
- Labels tie addresses to known entities. They can be wrong, so treat them as clues.
Rug-pull warning signs
- A few wallets hold most of the supply.
- The team can mint new tokens or block selling (a honeypot).
- Liquidity is not locked and can be pulled.
- A brand-new contract with hype and no audit.

Common questions
Is onchain data private?
No. Addresses are pseudonymous, but every transaction is public.
