Are you so stupid? You managed to make some money and then got cheated?

After 5 years of development, you still don’t understand smart contracts?

I will try to explain it all to you in today’s article.

I hope there will be no thieves in the world! ! !

First of all, you need to understand the essence of smart contracts.

A piece of program code can transfer your digital currency, and can help you with replacement, mortgage, pledge mining, etc., with multiple financial attributes.

But before any financial behavior can begin, at least two steps are required. The first is to click (enter), and the second is to authorize the wallet.

Many money disappears with one click. They are usually Trojan horse programs and crawler software that use various hacking methods to see your wallet secrets, private keys, mnemonic phrases and other information.

However, such Trojan horse programs will be attacked and deleted relatively quickly on the Internet. After appearing for a while, they will disappear. Therefore, they often ask you urgently to do something quickly and don't miss it.

There is another kind that is transferred away after authorization. In this way, people often do not look at the authorized amount when authorizing. Generally there is no upper limit.

Throwing out these two types, there are also smart contracts with backdoors, artificial manipulation, and false transactions. There are many.

The anonymity of blockchain also makes criminals more arrogant and domineering.

Improving personal security awareness never goes out of style.

First of all, do not keep the mnemonic words in your mobile phone, but keep them dispersedly.

In addition, key secrets should be avoided, such as birthday, ID card, initials, etc.

Don't arbitrarily authorize unknown dapps. If you have to play, choose a newly opened wallet.

Pay attention to the authorization amount.

After playing, cancel the authorization promptly.

Check the data on the chain to determine its authenticity.

Check with a third-party regulator to see if the smart contract has been vetted.

Be down-to-earth, steady, and don’t make money beyond your knowledge$SOL $ETH $BNB
