Happy new month everyone! So here’s the deal. I'm using Trust Wallet on my phone and it doesn’t give me a private key, just the 12 mnemonic words. Now I want to sign a message with my Bitcoin address but need that private key.

Dude, you don’t need to jump through hoops to sign a message. Just stay safe and avoid sketchy sites. Trust Wallet isn’t the best option to begin with. If you're on mobile, try BlueWallet instead. You can import your wallet using those phrases.

Totally agree with that! Your seed phrase will give you the private keys. Just import it into BlueWallet or Electrum. Those will let you sign messages. If you’re still keen on iancoleman, switch from BIP44 to BIP84 for the right keys.

Thanks for the tips! I usually see the iancoleman method around here, so I appreciate the alternative. Changed to BIP84 and it worked! Now I’m thinking about sticking with BlueWallet since it’s mobile.

Just a heads up, you might wanna ditch that seed phrase since you've entered it online. Risky move, man! That can lead to your keys getting leaked. The site you shared? Not too safe either. Stick with trusted wallets.

Yeah, if you’ve used your seed phrase online, better move your coins to a new wallet. You don’t wanna risk it. iancoleman isn’t the way to go when there are better wallets out there.

Seriously, listen to them! Entering your seed phrase on websites is a massive no-no. Signing messages on mobile is a hassle. Why are you even trying to sign from an empty address? Get a new wallet on a computer.

I checked that tool too, and it simply derives the address from your private key. You can’t sign a message using a native SegWit address with it. The address change in iancoleman? That’s different due to the BIP path.

I knew it would get messy! I created a new address just to test signing. My old wallet is untouched. I want to sign from my old wallet to prove ownership.

Trust Wallet, huh? It’s not great. Closed-source, and it lacks features like replace-by-fee. Users complain about transaction errors. We’ve had cases where people moved to Electrum and managed fine.

Wait, did you set up a new address or a whole new wallet? That matters when dealing with your seed.

Yeah, the replies here made it clear: Trust Wallet isn’t reliable and don’t copy-paste your seed. Compromising one key can mean trouble for all your assets.

I get what you’re saying. A Bitcoin address isn’t like a fixed account number. Your wallet generates new addresses all the time. When signing, it’s tied to your identity.

I’m using Trust Wallet now (zero balance). What wallet should I use for my assets on Android? Can you show me a legit link or something? There are so many fakes.

Always do your own research! Even if you find links, check they’re legit.

If there are official wallet sites, please share them! I wouldn’t wanna grab a fake from the Play Store.

For sure, Electrum is solid. Check out electrum.org. Make sure to verify GPG signatures before installing.

Unstoppable wallet is also good. Look into horizontalsystems.io. They support Bitcoin and altcoins. Use Walletscrutiny to find secure wallets.
