It is extremely important to note that the (only) official electrum is a BTC wallet. And the only official URL is https://electrum.org/.
Since electrum is open source (https://github.com/spesmilo/electrum), a lot of people forked the code and modified it to support different currencies.
However, this forks should NOT be regarded as safe. Without code reviewing/auditing, bad surprises may happen.
This does not mean that all forks are malicious. But there are malicious / buggy forks around under the name 'electrum'.
