Hello Sir, Recently I downloaded electrum wallet for BTC.Now I want to Sign message.I tried so many time and its showing signature verified but When i am trying to check
online it's show me,Message failed to verify! No Transactions yet.
Where exactly "online" are you attempting to use your signed message? Are you attempting to claim coins/tokens from an ICO or giveaway like Stellar Lumens or something?
Are you using a standard wallet or a multisig/2FA wallet?
