How to read a blockchain transaction on an explorer
Decode from, to, value, fees, status, and token transfers using public block explorers—without trusting random screenshots.
Block explorers are public search engines for chain data. Ethereum’s canonical public explorer pattern is well documented on ethereum.org and on explorer help pages (for example Etherscan’s knowledge base). The same fields appear on many EVM-compatible explorers, including PulseChain’s public explorer.
Open a transaction
Paste a transaction hash (a long hex string starting with 0x on EVM chains) into an explorer for the correct network. Wrong network = empty or unrelated result. Always confirm the network name in the explorer header.
Fields that matter
- Status — Success vs failed/reverted. A failed tx can still consume a fee.
- From / To — Sender and recipient addresses. For contract interactions, “To” is often a smart contract, not a person.
- Value — Native coin moved (ETH, PLS, etc.). Token transfers often appear in a separate “Tokens transferred” or “Internal” section, not only in the top value field.
- Transaction fee / gas — What the sender paid validators/miners to include the tx. Gas used × gas price (plus any priority fee, depending on the fee market).
- Block / timestamp — When it was included. Pending means not yet in a block.
- Input data / method — For contracts, explorers may decode a function name (e.g.,
transfer,swap). If it says “Unable to decode,” you can still see raw hex; do not invent meaning. - Logs / events — Emit records contracts use; token transfers usually show here.
Reading token moves
ERC-20 style tokens do not always change the native “Value” field. Look for Transfer events: from, to, amount, and token contract address. Verify the token contract against a project’s official documentation—lookalike tickers are a common scam pattern.
Healthy skepticism
- Screenshots can be edited; open the hash yourself.
- Address labels on explorers are sometimes community-submitted—treat them as hints, not proof.
- “Tx successful” does not mean “you got the airdrop you expected”; it means the chain executed whatever calldata was submitted.
