Steps
Start by confirming Mainnet, Nile, or Shasta in the header. Paste a hash like 0x03a0a5aa42097b0e24… or an address such as TAD6MwHIln… to open the detail page. Validate status, confirmations, energy and bandwidth cost, then cross‑check values in a secondary explorer if the decision is critical.
Open the token/contract panel to match symbol and decimals and review event logs. For transfers, compare the first and last characters of sender TAD6Mw… and receiver Th5sa0… to avoid clipboard mistakes. Use bookmarks for trusted explorers to mitigate phishing risks.
When results look odd, clear cache, refresh, and try another browser. If pending persists, check resources on the account page; staking or adjusting resources can help. Record the TX ID 0x03a0a5aa4209… for audits and support tickets.
