Ethereum Transaction Tracker

WHAT IT DOES

Ethereum Transaction Tracker is a read-only analytics tool that gives you a complete picture of any Ethereum transaction. Enter a transaction hash and the app fetches the transaction details, receipt, logs, and block data. It parses token transfers for ERC-20, ERC-721, and ERC-1155 standards, decodes internal transactions where the RPC supports tracing, and calculates the actual transaction cost using the effective gas price from the receipt. It also shows the transaction status, block number, gas used, nonce, and a count of logs. All of this is presented in a clean, card-based interface with copyable addresses and Etherscan links.

HOW TO USE

1. Connect your wallet or select a network from the dropdown. The app uses your wallet's RPC if connected, or falls back to a public provider for the selected network.

2. Paste a transaction hash (0x...) into the input field.

3. Click "Lookup" to fetch and display the transaction data.

4. Review the details: status, block, from/to addresses, value, effective gas price, gas used, transaction cost, nonce, and log count.

5. Scroll down to see parsed token transfers and internal transactions (if available).

6. Use "Clear" to reset the view and enter another hash.

ONE TECHNICAL SECTION

Public RPC providers impose different limits on eth_getLogs block ranges. A request that spans too many blocks will fail with a "block range too large" error. Many tools give up at the first refusal, returning incomplete results. This app handles the failure by detecting the error and automatically reducing the chunk size by half, then retrying. This adaptive backoff continues until the request succeeds or the chunk size falls below a minimum threshold. The approach ensures that the scan completes even when the provider's limits are restrictive. It also accounts for providers that enforce a maximum number of topics or response size, retrying with narrower filters when necessary. This is the difference between a tool that fails silently and one that delivers a complete transaction history.

WHAT IT CANNOT SEE

This tool cannot track transactions that occur on other chains — it is EVM-only and only works with the network you have selected. It cannot see off-chain activity such as events emitted by indexers, relayer transactions that are not recorded on-chain, or state changes that happen outside of the EVM. It cannot prove that an address controls a private key or decrypt the contents of mempool transactions. Historical data is limited by the RPC's archive node availability; if the provider does not store full historical state, older logs may be missing. The tool cannot detect transactions that have been reorged out of the chain or identify the real-world entities
