  15. Why do I not see my funds or have different addresses after restoring mnemonics from Coins on another non custodial wallet?

    This situation may occur if the wallet does not support the latest technology (eg Segwit). In this case, you need to find a wallet with the same technology as Coins.

  16. I have reset the phone settings and my wallet doesn’t work.

    Resetting the phone settings causes the loss of the private key. For your safety we do not store such data in the application. To regain access to the wallet, you must restore it from the saved mnemonics phrases.

  17. I can’t send BTC to my Coins BTC address? BTC address is invalid, why?

    There are three BTC address types:

    1. Legacy (P2PKH): addresses start with a 1
    2. Nested SegWit (P2SH): addresses start with a 3
    3. Native SegWit (bech32): addresses start with bc1 (we use this type in Coins)

    Legacy address is the original BTC address. SegWit is the newer address format with lower fees. We use SegWit address because it guarantees faster transactions and lower fees but, not every wallet or exchange has upgraded to support the new SegWit address format and therefore, some wallets/exchanges can only send to Legacy addresses. In Coins we only support Segwit addresses. We are working on implementing legacy addresses. When it is possible we will inform You.

  18. What happens if my phone gets stolen or lost?

    You can always restore your wallet on another phone. You need to:

    1. Download the COINS app.
    2. Choose the option "Restore wallet" under My Coins tab
    3. Write your secret key: 12 or 24 words (mnemonic phrases).

    Restoring your wallet is only possible if you have your mnemonic phrases. Without those mnemonic phrases, there is no other option to get access to your funds.

  19. What happens if the Coins app disappears, can I access my funds from another wallet?

    Yes, of course. We use the popular cryptocurrency standard HD Wallet (Hierarchically Derived) BIP39. So You can get access to your funds in other wallets that support the BIP39 standard. To get your funds in another wallet, you need to write your mnemonic phrases from the COINS app (12 words).
