Turns out every transaction has a unique code called a TXID. I found a clear breakdown at https://paybis.com/blog/glossary/what-is-a-txid/ that explained how to copy that 64-character number from my wallet, paste it into any blockchain explorer, and see exactly where my transaction was in the queue. It also covered why things get stuck (low fees, network congestion) and what "pending" actually means. Now I always check the TXID before panicking. Super useful for anyone sending crypto – bookmark this one.
