An explorer is an indexed view
A block explorer is useful for locating transactions, logs, verified source and token metadata. It has its own index and presentation layer. If the interface has not indexed a recent transaction yet, that absence alone does not establish the transaction's outcome.
Start from the official network guide
Robinhood lists robinhoodchain.blockscout.com for mainnet and explorer.testnet.chain.robinhood.com for testnet. Use those links from the official documentation rather than selecting an explorer by a similar domain name. Save the chain ID alongside each explorer URL in application configuration.
Build a cross-check
{"jsonrpc":"2.0","id":1,"method":"eth_getTransactionReceipt","params":["TRANSACTION_HASH"]}- Confirm eth_chainId on the endpoint used for the cross-check.
- Compare receipt blockHash and blockNumber with the explorer record.
- Compare the exact log address and topics when debugging a token transfer.
- For a contract, inspect deployed code and verified compiler metadata rather than trusting the displayed contract name alone.
Record evidence that survives the interface
Store transaction hashes, chain ID, block hash and the fields your application relied on. An explorer label can change and a page can temporarily lag. If RPC and explorer disagree, distinguish a wrong-network link, indexing lag, a replaced chain view and a genuine provider issue. Give support the exact transaction and both observations; a screenshot of a token ticker is usually insufficient to identify the record.
