How to read on-chain data

The genuinely useful property of a public blockchain is that you do not have to take anyone’s word for anything. Most claims about a token can be checked in a few minutes, and most of them do not survive it.

1. Holder concentration — start here

Any block explorer shows a token’s holder list. This is the highest-value check available.

What to look for: what share do the top ten wallets hold? If a handful control most of the supply, they can exit into whatever liquidity exists and leave everyone else with nothing. This is the structural precondition for the most common way small tokens collapse.

How it is obscured: supply split across many wallets that are all controlled by one party. Look at funding history — wallets funded from the same source at the same time are a strong signal. Also identify which large holders are exchange wallets or locked contracts, since those are not the same as an individual holding a position.

2. Liquidity depth and lock status

For any token traded on a DEX, check the size of the liquidity pool relative to the token’s supposed market cap. A token with a $50m notional valuation and a $80,000 pool cannot be exited by more than a handful of holders.

Also check whether liquidity is locked and until when. “Liquidity locked” is meaningless without a date — a 30-day lock simply schedules the earliest possible rug pull.

3. Genuine activity

Active addresses and transaction counts are the standard usage metrics, and both are trivially inflated: one person can generate thousands of addresses and transactions cheaply on a low-fee chain.

Better questions: are addresses transacting repeatedly over time, or appearing once and never again? Is activity distributed, or concentrated in a few wallets cycling funds? Does it correlate with anything real, like a product launch, or only with an incentive programme?

4. Volume, and how it is faked

Reported volume is among the least reliable figures in crypto. Wash trading — buying and selling with yourself — is cheap on low-fee chains and inflates volume arbitrarily.

Compare reported volume against liquidity depth and holder count. Enormous volume on a token with a tiny pool and few holders is not a market; it is a bot.

5. Supply and unlock schedule

Check circulating supply against total supply. If most tokens are locked, find the vesting schedule — those unlocks are dated sell pressure and routinely coincide with sharp falls. A token that looks reasonably valued on circulating supply can look very different fully diluted.

6. Exchange flows — read with care

Large transfers to exchanges are often reported as bearish (preparing to sell) and outflows as bullish (moving to storage). Both readings are weak. Exchanges move funds between their own wallets constantly, and those transfers look identical on-chain to a holder depositing to sell.

Treat flow analysis as one weak input, not a signal.

7. Contract permissions

For a token contract, check whether it is verified, and whether it includes functions letting the owner mint unlimited supply, pause transfers, blacklist addresses or change fees. Any of these means the deployer can unilaterally destroy your position. Unverified contracts should be treated as hostile by default.

A practical checklist

• Top-10 holder concentration, with exchange and locked wallets identified
• Liquidity depth versus claimed market cap
• Liquidity lock, and its expiry date
• Address activity over time, not just totals
• Volume sanity-checked against depth
• Circulating versus total supply, and the unlock calendar
• Contract verified, and what privileged functions exist

Applied honestly this eliminates most tokens in under ten minutes. That is the point — the aim is not to find winners but to discard obvious losers cheaply.
