Efimer Security

How does Efimer connect to your exchange accounts?

Efimer connects to your exchange accounts using API keys. We offer three important pillars of security around API connections. Depending on the exchange, you can access some or all of these when you trade with us:

Sign Center

Sign Center is a secure API key storage isolated at both infrastructure and access levels to ensure the security of our systems. When Efimer makes a trade request with an exchange, Efimer servers ask the Sign Center to sign the transaction. This protocol is similar to how Metamask or Ledger signs a transaction.

When you create an API key with your exchange, you can specify an IP whitelist. The IP whitelist can be used to restrict the API key to certain IP addresses. You can use this tool to specifically authorize official Efimer IP addresses — and block any others. Your created API key can’t be added to any other account on Efimer — which means they cannot be used to initiate trades with your exchange account if the request doesn’t come from your Efimer account.

Fast Connect

Exchanges that are focusing on better serving traders are beginning to offer Fast Connect. Fast Connect can help users quickly authorize specific account permissions, create API keys, and automatically connect to third-party API link platforms.

Fast Connect allows you to log in to your exchange account via the quick connect function on Efimer software. It can automatically generate API keys and bind to our software, ​​so you can start using Efimer’ services without manually creating API keys.

Transactional access only

Our system tells your exchange account to start and close deals. It has zero access to withdraw or transfer fiat or cryptocurrencies. Your login information for your exchange is never revealed to our system. No backdoor or cache can be exploited because the API deliberately does not have the functionality to request any of your personal information from the exchange.
