Thank you admin for this fast response, I think it would be better if after the prize is sent, you also give us the tx id so we can check the prize on chain. Thank you
I agree. It is easier for us to control received payments if we get some message after it is completed.
Because admin may pay and we may take a few days to notice the payment. This happened to me in a giveaway that I won a prize a few weeks ago, which took many weeks/months to be paid and when i received the payment i didn't noticed it.
Use some of the options offered by other services.
For example, on bscscan.com it is possible to set email notifications for each transaction.

@bitmover, there is also a free API, maybe you can create some useful tool and customize it for yourself.
FYI :I sometimes use wallet software to receive erc20 or bep20 tokens, such as Trust wallet and Safepal wallet. There is a slight problem when we get a token that does not yet know its smart contracts or has its smart contracts added, the notification does not appear.
And sometimes the notification is only for native coins such as Bitcoin, Ethereum, BNB, Polygon, Polkadot, Solana. And for tokens like erc20, bep20, sometimes the notification does not appear on my smartphone either.

Btw, I just added ALTT tokens with smart contracts that have been embedded in the altcoinstalks forum, and it turns out that 420,000,000 ALTT tokens have been added, I didn't get any notification and I also forgot what event I got the rewards from.
