BNB Chain: Things to Avoid

1. Don't send real mainnet tokens to BNB Chain testnet

BNB Chain testnet is strictly for testing purposes. Normal users can play with it to try any features. For example, crypto facility providers, such as wallet creators, can test integration with BNB Chain, and traders can test their trading strategies. But all tokens on testnet are testing tokens, which have no monetary or benefits associated with them. BNB Chain testnet funds don't equate to BNB Chain mainnet funds or account funds.

Please don't send any real mainnet tokens (BTC, ETH, BNB etc.) to the BNB Chain testnet. Your tokens will be lost and will be unrecoverable. If you would like some test tokens, please go to the test fund faucet. It is free, you just need a account and 1 BNB in the account at the time of applying (you can spend the 1 BNB after getting the test fund), and you can get fund for multiple addresses with one account.

2. Don't share your mnemonic phrase or private key with anyone

You can lose control of your funds if you share your mnemonic phrase or private key with someone. If you lose your funds, then not even BNB Chain validators or Binance can help return your funds.

So please keep your private key only for yourself, even if it's Binance customer support or CZ himself is asking for it.

3. Don't lose/forget your mnemonic phrase

As described above, when you lose your mnemonic phrase and private key, you are at risk of losing access to your funds. Even BNB Chain validators or Binance cannot help recover your private key or mnemonic phrase. You must record your mnemonic phrase safely and make sure you (and only you) can find it when you need it.

4. Don't forget to write down your mnemonic phrase

A mnemonic phrase can help you recover your private key. It's usually the only way to recover the private key, so please write it down and keep it in a safe place.

5. Don't keep using mnemonic phrase or private key to unlock your wallets

If you keep using the mnemonic phrase and private key, you have a much higher chance to lose them due to phishing websites or applications. Private keys and mnemonic phrases should be only used to recover your keystore file or hardware wallets or mobile wallets. 

It's highly encouraged always to use Trust Wallet, hardware wallets, or your keystore file to unlock your wallets.

6. Don't use SDK or Trading Bots that aren't 100% trustworthy

When you use SDK or trading bots on DEX, you may have to input your private key into the libraries or the software, by that time, you may expose the private key to a leak or risk falling victim to phishing. Please ensure the SDK and Trading Bots libraries/software are 100% trustworthy. It's highly encouraged you use a Signing Service (coming soon).

7. Don’t send large orders at once

Binance DEX uses a different matching logic from The biggest difference for normal users would be on trading large, aggressive orders. If you send them in one go, the match engine would consider there is a big buy or sell surplus and conclude a much worse trading price for you. So please send small pieces if you want to buy or sell a large amount. For an example of EOS.B/BNB pair, if the best buy order is 100 EOS.B at price 0.39, the 2nd best is 100 EOS.B at 0.34, and the 3rd best is 100 EOS.B at 0.20, sending a sell order of 300 EOS.B while no other sellers would not give you a price of 0.39 or 0.31 (the average price you may get if traded on against the same order book), but very likely 0.20. Here the case for a less liquid market, it is better to send 3 orders each with 100 EOS.B. 

8. Don't associate any benefits or gains with tokens on BNB Chain testnet

As described above, tokens on BNB Chain testnet are purely for testing purpose. The tokens and the testnet funds in your addresses may be subjected to reset during testnet upgrades. Please be careful about scams or phishing that promise any benefits or gain on tokens on BNB Chain testnet. The tokens on testnet have no monetary value.
