FAQs about the Multi-Chain wallet

Is the Multi-Chain Wallet safe?

Coin98 Wallet is a non-custodial wallet, which means all users have full control over their own assets. No one else has access to your wallets unless authorized by you and you only. The email address used to register for your account only adds an extra layer of security for the app, saves the transaction history and the in-app settings for the next log in sessions. Your email is independent and isn’t directly linked to your assets.

Do I have to pay for the transaction fee when using a Multi-Chain wallet?

The fee when making a transaction on a blockchain is called a gas fee and it is paid for miners and validators to authorize this transaction. However, the gas fee is different on each blockchain and will be paid with a different coin/token. For example, the gas fee on Ethereum is paid with ETH, BNB on Binance Smart Chain, MATIC on Polygon, etc.

Can I create multiple Multi-Chain wallets?

Absolutely! You can create as many Multi-Chain wallets as you want, as long as you store their Passphrases carefully.
