Bofu Chen This problem is somewhat similar to the one I encountered when testing the superworld contract. James Chien’s reply was that too few transactions would not trigger explorer updates.

Bofu Chen I want to workaround this issue with a script sending transactions every 30 seconds.

1. Is the interval sounds good to you? (Cost 16000~17000 Testnet NUM per year by the current gas fee)
2. If yes, can you send Testnet NUM to 0x2bF66EBDE9E53988ecbd9eC6959B12BeE7ce7f79 ? (It's best not to use service wallet for that increases chance of nonce collision when testing on QA site)

James Chien The wallet you shared yesterday is backend's wallet

0x64f7f6b122daaD47Fc427B2B8b620D6130BCb4cE

Could you share the mnemonics of 0x2bF6 with me? Thanks

Bofu Chen Let's use another wallet 0xA1C677E31E464De4600e5B71F607241D635cA6e1 , I'll send the mnemonic now

James Chien I think it makes more sense that the explorer can show the latest transaction natively, and it should be an issue in Blockscout.

Can you help check if there is an existing upstream issue? Thanks

Bofu Chen I’ve already checked before and can’t find any such issue. I can create a new issue for this.

This happens whenever I send a transaction on testnet.

The workaround seems to be not working. I sent 5 transactions earlier and still nothing appears for about 15-20 minutes.
