One of the most stable and capable layer 1 chains is soon to have a mandatory hard fork, which will make the chain support Bitcoins Taproot. Here's the tldr of what is needed to know.
1. When is the Qtum Hard Fork?
For Qtum Mainnet at block 2,080,512, approximately 9:45 pm UTC on July 31st. QTUM Testnet hard forked on June 1, 2022.
2. I have a Qtum Core wallet. What do I need to do?
Update to version 22.1 (https://github.com/qtumproject/qtum/releases) as soon as possible, then relax and wait for the new features to be automatically activated at block #2,080,512.
3. If I use the Qtum Web or Electrum wallet, do I have to update for the hard fork?
Nope, just relax.
4. I have a Ledger wallet (or another hardware wallet) do I need to do anything or do an update for the hard fork?
Nope, just relax. The update is mandatory only for the Qtum Core wallets Qtum-Qt and qtumd.
5. I use another 3rd party QTUM wallet for QTUM, do I need to update it for the hard fork?
Nope, just relax.
6. I have QTUM in an exchange account. Can I leave them there for the hard fork?
Yes.
7. Is there a new coin from the hard fork?
The purpose of the hard fork is to upgrade the Qtum blockchain, not to produce a new coin.
8. What are the new features for the hard fork?
Addition of Taproot/Schnorr signatures, deploying a new Ethereum Virtual Machine evmone, and bug fixes. See the release notes at https://github.com/qtumproject/qtum/releases/tag/v22.0
9. What happens if I try to send or stake coins with an old version Qtum Core wallet after the hard fork?
You will temporarily lose the coins. For the recovery instructions, see this blog https://blog.qtum.org/you-missed-the-hard-fork-now-what-996bab6639de
10. Where can I get more information about the hard fork?
