Dear Cobo Users,

In line with the best practice recommendations from the official TRON documentation, and to further optimize the transaction confirmation mechanism, Cobo will adjust the confirmation numbers for TRON mainnet and its tokens starting August 26, 2025.

Adjustment Details
 • Confirmation Number Adjustment: From 1 to 20
 • Secondary Confirmation Mechanism: When the irreversible block height ≥ the block containing the transaction, the transaction will be considered finalized

Impact of Adjustment
 • No impact on deposit/withdrawal efficiency: This adjustment only affects the transaction confirmation strategy and will not reduce the speed of deposits or withdrawals
 • Improved user experience: Confirmation time will be shortened, allowing users to receive deposit callback notifications more quickly
 • Enhanced security: With the secondary verification mechanism, irreversible block confirmation is ensured, effectively reducing potential risks

For more details, please refer to the Official TRON Documentation.

Please feel free to contact us if you have any questions.
