What Unheld waits for on Tron
| Fact | Tron |

| Assets Unheld lists here | TRX and USDT |
How the time is worked out
- A confirmation depth of 19, with one block about every 3 seconds, comes to about 57 seconds.
- The block time is TRON Developer Hub’s own figure, read on Oct 3, 2026.
- Unheld’s own detection and checks come on top of that: usually a few seconds.
- The clock starts when the payment is first included in a block. Waiting to be included is not counted: a busy network or a low fee can add to it, and the payer’s wallet usually sets that fee.
- A block time is an average or a target set by the network; any single block can arrive sooner or later.
Why Unheld waits for confirmations
Until enough blocks are built on top of it, a payment can still be reversed. Unheld marks an invoice paid only at the depth set for each network, so goods are not released against a payment that can still disappear.
Tron confirmation questions
How many confirmations does Unheld wait for on Tron?
A confirmation depth of 19. Until then the payment shows on the invoice but is not yet credited.
How long does a payment on Tron take to be credited?
About 57 seconds after the payment is first included in a block — the time the network takes to reach the depth — plus a few seconds for Unheld’s detection and checks. The time spent waiting to be included is not counted.
How long does USDT on Tron take?
About 57 seconds after the payment is first included in a block, at a confirmation depth of 19, plus a few seconds for Unheld’s detection and checks.
Can a payment be credited sooner?
No. Crediting earlier would treat a payment that can still be reversed as final. The depth is a security setting, not a speed setting.
