Your xpub key.
What an xpub is
An xpub (extended public key) is the public half of your wallet's master key. From it, anyone can derive every receiving and change address your wallet uses — but nobody can derive the matching private keys. It's how watch-only wallets work.
Why you might want one
Load your xpub on a separate machine to monitor balances without exposing signing keys. Useful for cold storage: keep the seed offline forever, watch incoming payments from a laptop.
Is it safe to share my xpub?+
Sharing an xpub does not let anyone spend your XEC — they cannot derive private keys from it. But it does expose your entire balance and transaction history to whoever has it. Treat the xpub as financial privacy, not financial security.
Where do I find it in Electrum ABC?+
Open the wallet, go to Wallet → Information. The 'Master Public Key' field is your xpub. There's a copy button next to it.
What can someone do with my xpub?+
They can generate every receiving and change address your wallet will ever produce, watch your balance over time, and reconstruct your spending pattern. They cannot move funds. Useful for a watch-only setup; harmful if leaked publicly.
