Bitcoin Wallet client Electrum may add support for the Lightning network.
Bitcoin Wallet Electrum has released the official version of 4.0, adding support for lightning networks and other features.
Bitcoin desktop wallet client Electrum has released a 4.0 beta version, adding several important updates, including support for the Lightning network, nearly a year after the previous version of Electrum, 3.3.8 (last July). In the 4.0 beta version, Electrum mainly added features such as PSBT (partially signed Bitcoin transactions), Lightning Network, watchtowers (暸 watchtowers) and Submarineswaps (subliminal switching).

If someone's Electrum wallet connects to one of these servers and tries to send a BTC transaction, they see an official message telling them to update their Electrum wallet, as well as a scam URL.
Electrum wallets have been hacked in recent days and nearly 250 bitcoins have been stolen, according to blockchain security team Devi Security Labs. This attack, confirmed by Electrum, involves creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is an ongoing phishing attack on Electrum users and advised users to download wallet apps from the official website." Mars Finance reminds users not to install electrum wallets from unknown sources.
At the time of writing, at least 1,450 BTCs (stolen by one user, antimalware firm Malwarebytes and Electrum) had been stolen in phishing attacks that faked Electrum upgrade tips, with a total value of approximately $11.6 million.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding users to check the authenticity of the client's source before logging in. The team published its official website, and electrum clients downloaded elsewhere may be problematic.
Bloom Filters allows the reality SPV (simplified payment confirmation) client to simply download the chain fast title without having to store all transactions in the chain block locally. For example, a client can query the address of a node to retrieve all relevant transaction data and verify the block of information by the title information of the chain block. Several security vulnerabilities were identified in 0.8.0, and the operation of Bloom Filter will allow an attacker to carry out a denial-of-service attack. When a node is overwhelmed by disk read/write capabilities, causing them to synchronize behind several chunks, someone sends information through the client causing an outage.
Several wallets - like Coinomi, Electrum and Wasabi - moved straight to this.
