Of course, there are wallets that are not designed according to BIP rules, such as Electrum, which was the first to use mnbike patterns, and the first determinizer wallet, which was introduced in 2011, and later Trezor's introduction of the mbike rule BIP-39, which became a recognized industry standard with its widespread use. Electrum and BIP-39's mone word rules are similar, but BIP-39 uses a fixed set of 2048 thesaver, electrum uses another thesaver, but can be compatible with BIP-39's monemone thesaver, reverse is not compatible.

According to Reddit user u/normal_rc, electrum's wallet was hacked and nearly 250 bitcoins (243.6 BTCs, nearly $1 million) were maliciously stolen, according to coinelegraph. Electrum then confirmed that the attack included creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is a persistent phishing attack on Electrum users" and warned users not to download Electrum from any source other than the official website.

For example, if you create a node that is used for the sign"/test/lock, and then use him as the parent node, you can create a child node with the same prefix under that parent node, assuming that the same prefix is "/test/lock/seq-", indicating an ordered type when you create the child node. If you are the first child node to be created, the resulting child node is /test/lock/seq-0000000000000, and the next node is /test/lock/seq-00000000001, and so on.

It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
