How to stay safe​

Wallets are a bit of a shift in thinking. Financial freedom and the ability to access and use funds anywhere comes with a bit of responsibility – there’s no customer support in crypto.

Take responsibility for your own funds​

Centralized exchanges will link your wallet to a username and password that you can recover in a traditional way. Just remember you’re trusting that exchange with custody over your funds. If that company is attacked or folds, your funds are at risk.

Write down your seed phrase​

Wallets will often give you a seed phrase that you must write down somewhere safe. This is the only way you’ll be able to recover your wallet.

Here's an example:

Don’t store it on a computer. Write it down and keep it safe.

Do Your Own Research​

If you use a web wallet, bookmark the site to protect yourself against phishing scams.

Remember transactions can’t be reversed and wallets can’t be easily recovered so take care.

Tokens not visible after withdrawing from Binance​

Many users who interact with a centralized exchange like Binance eventually want to withdraw to a wallet that they fully control, like MetaMask. So once you've used their withdraw form, what could be scarier than not seeing your tokens?

First, you'll need to use the MetaMask add Custom Network feature to add the BNB Beacon Chain or BNB Smart Chain's RPC URLs endpoints to your MetaMask.

Once you've added the BNB Beacon Chain or the BNB Smart Chain to your MetaMask, you will be able to select different networks to view the assets (you may need to add Custom Tokens too) held by your selected account on that network.

How Much BNB You Need To Send Tokens​

if you try to send tokens without having any BNB in your account you will be told you have insufficient funds. This means you do not have enough BNB in your account to cover the cost of gas. Each transaction (including token and contract transactions) require gas and that gas is paid in BNB. You can think of this like a transaction fee.

You can remedy this by sending 0.001 BNB to that account in order to be able to make the transaction.

A standard Ether transfer TX will be 21000 gas & a gas price of 15 Gwei.With tokens, the amount of gas is typically gas, so the total TX fee increases to 0.002 BNB - 0.003 BNB.
