Your funds are stored safely on your exchange account, BitSpreader just executes orders on your behalf on the exchange using the API key that you have provided.

BitSpreader never does any transfers of your funds.

For further increase of security we strongly encourage you to not provide any API keys that have privilege to execute transfers - please refer to your exchange API key settings to make sure to reduce the API key privileges just to the most necessary (balance, history, trading).

Your data is encrypted

Your API keys are encrypted and available only in the internal layer of the BitSpreader services safely hidden behind the firewalls and not accessible from the website.

For managing your API keys we follow write-only pattern - once you have provided your API key, the BitSpreader has stored it internally for the trading purposes and doesn't expose it even to you for editing. If you need to update the API key - you need to delete the old key and provide the updated one.

In order to access the API Key management panel, click on the “API Keys” option in the sliding sidebar on the left side of the screen. Users can define any number of API keys with following limitations:

• There can be only one API key for given exchange
• After adding an API Key, the user cannot see it and cannot update it - the only action that can be performed is deleting the API key. In case the user made a mistake when entering the api key, user needs to delete invalid api key and add the correct one again

Click “Add API Key” button, select an exchange to which you don’t have any API key yet, provide API key and secret key. Some exchanges may require you to provide additional parameter i.e. passphrase - please provide it in the last box.

When creating a new API Key on the exchange please make sure that the API Key has following permissions:

• Access to balances/wallet information
• Trading on futures
• Accessing transaction list

After entering the API Keys management panel you see the list of exchanges to which you have active API keys along with the status of the API key. The key can have INVALID status in case:

• Key data was invalid
• Key has expired and is no longer accepted by the exchange
• The exchange returned and API key error during the initialization

After clicking an API Key on the list, you can see the first three characters of the api key (to enable the user to identify the key in case there is more than one on a given exchange) and an option to delete this key from BitSpreader.

Binance

API KEY setup

Binance has two separate APIs for futures - one for coin-margined (COIN-M) futures and another one for usds-margined (USD-M) futures. You will need to define two separate API key definitions in BitSpreader if you want to trade on both types - select proper exchange name on the exchange list when defining API Key:

• Binance USD-M futures - for USD margined
• Binance COIN-M Futures - for coin margined

On the Binance side you only need to define the key once and you can use the same key value and secret for both API key definitions in BitSpreader
