USDT TRC20 Transaction Status: Expired
Every TRON transaction carries a built-in expiration timestamp, and missing that window produces a distinct failure from a simple pending state.
Why transactions expire
When a wallet builds a transaction, it references a recent block and sets a short expiration window from that reference point. If the transaction isn't included in a block before that window closes — usually because it was never successfully broadcast — it's treated as expired rather than pending forever.
How this differs from just being slow
Because TRON confirms new blocks roughly every 3 seconds, a transaction that was actually broadcast successfully almost never has time to expire — it either lands in the next block or two, or it never really left the sender's device in the first place.
What to do
Treat an expired transaction the same as one that was never broadcast: check the sender's connection and Energy/TRX balance, then resubmit. There's no separate on-chain trace to recover — an expired transaction never actually executed.
