If you can share the URL here, that would be useful. I think this may happen in cases where Bitcoin testnet is forked or otherwise having consistency issues, which unfortunately is not unheard of on Bitcoin testnet.

@Shadowfiend sorry, i made this issue before I realised that I have to report URLs with every bug I encounter and now no one can move past step 2, since 100 tBTC are minted and we got stuck into limit. So I don't have many chances to reproduce this, I believe. But if I will be lucky to encounter this one more time, I will surely report back

Cool cool. Going to leave this open a few more days and then close until we see it resurface, in that case!

@Shadowfiend good (and bad simultaneously) news. I managed to get this bug one more time. https://dapp.test.tbtc.network/deposit/0x003D93b8A45D399AA164e764eCa365A0f0C8d590/prove Here's URL of my minting process. Step 4, happens after I send 0.5 testnet btc to specified address and after 1 confirmation. Here's testBTC transaction itself: https://sochain.com/tx/BTCTEST/a952648653c299ba0bfa901a373d9734d5af6b8e0dadce794fe97f679930ddea

What dapp says: failed to get merkle proof: [Error: failed to get transaction merkle: [tx a952648653c299ba0bfa901a373d9734d5af6b8e0dadce794fe97f679930ddea not in block at height 1,802,411]]

while clearly my test BTC transaction went into this block: Block No. | 1,802,412

For what it's worth. After I submitted URL and logs, I tried to reload page. Now it passes this error and getting stuck at "Reverted by EVM" error, which is ok, since we have clogged 100 tBTC limit.

My guess here is that we need to introduce a retry… Let me dig in and see if I can find anything in the Electrum logs that would indicate how we ended up in this situation.
