Reading block explorers like a desk analyst
Transactions, token flows, holders, approvals — the four views that answer nearly every onchain question.
The transaction is the ground truth
Prices are opinions; transactions are facts. Paste any hash into the chain's explorer and read: who sent what to whom, which contracts executed, what fees were paid. If a claim cannot be confirmed in an explorer, treat it as marketing.
Token pages answer "should I touch this?"
Before interacting with any token: holders (concentrated top holders can dump on you), contract verification (unverified code hides behavior), and allowances you have granted it. A token with ten holders and unverified code is not an opportunity — it is someone else's exit plan.
Wallet pages answer "who is behind this?"
Labels, funding sources, and history reveal whether an address is an exchange, a known fund, a fresh shell, or a serial dumper. Follow the funding trail backward: wallets are cheap to create but histories are expensive to fake.
Approvals complete the picture
The approval checker shows what your wallets have authorized. Combine it with the above: unknown token + active unlimited approval + recent interaction equals an open door. Revoke first, investigate second.
Risk note: cryptocurrency trading, leveraged perpetual futures, and automated algorithmic strategies carry significant risk of rapid and total financial loss. Never risk funds you cannot afford to lose completely. Nothing in this lesson is investment advice, a recommendation, or an offer to sell any product.
Checklist
- I can trace where funds went from any transaction
- I check holders and approvals before touching a new token
