Electrum is free software used by many cryptocurrencies websites, including merchants and exchanges, to store bitcoins. Anyone can run an Electrum server, and the software supports hardware wallets such as Trezor, Ledger, and Keepkey. Enhanced features include multi-signal and the ability to sign transactions using cold storage devices that are not connected to the network.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum wallets are fast and have few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.
When an Electrum wallet queries a third-party Electrum server, the server can link two transactions together and know which address is a zero address.
Electrum is a well-known light wallet for Bitcoin that adds new features such as server authentication using SSL to prevent MITM attacks. So unlike other Bitcoin light wallets, Electrum cannot communicate directly with different versions of Bitcoin full nodes, and each startup connects to electrumserver to communicate, and electrum.
Use BitHD shields and blades to prevent Electrum wallet "message defects" attacks.
Note: Electrum-XZC is derived from Electrum and uses different seed phrase criteria, so it cannot be imported.
Ledger Nano S supports more than 1,000 coins and tokens, including Bitcoin, Ether, Ether Classic, Litecoin, Ripple, Dog Coins, Zcash, Dash, and many ELC-20 tokens. Nano S can interact with online wallets, MyEtherWallet, Mycelium and Electrum.

According to the slow fog zone, the Phishing attack by Electrum forged upgrade tips has stolen at least 200 BTCs, and this attack cannot be avoided by upgrading Electrum alone, requiring the entire ecological service to make corresponding changes (because Electrum is not a full node, and then on the transaction broadcast and the corresponding server has a message communication, the attacker can also deploy a malicious server)
Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
