What Kind of Crypto Custody Service Do You Need?
Companies providing crypto custody services should clearly demonstrate how they ensure these principles and how they are applied throughout the life cycle of crypto assets.

Last week at the Istanbul Blockchain Week 2023 event, in the panel where I spoke on behalf of CSATR, we shared our views on the impact of cloud solutions in managing security risks of blockchain technology with Mehmet Uner from Microsoft Turkey and Anıl Oz from Turkcell. Especially after the presentation introducing CSA’s work in the field of blockchain risk and security management, the feedback we received indicates that we have achieved our goal.
During the event, we noticed that companies providing cryptocurrency custody services also participated. I believe that with institutions such as banks in our country starting to enter the crypto sector, solutions for securely storing crypto assets are becoming increasingly popular.
The first of the asset storage approaches used in the crypto world is hot storage solutions. In these solutions, wallets are constantly online and connected to the blockchain. Hence, transactions can be executed rapidly. On the other hand, cold storage solutions are also known as offline wallets and are physically isolated from other systems. These solutions, typically preferred for storing private keys, require more time for transaction approvals and execution. Therefore, they are generally used for digital assets stored in the long term. Warm storage solutions try to combine the advantages of these two approaches.

Safe Storage Solutions
Crypto custody service providers present at the event, like Fireblocks, offer secure storage solutions to individual and corporate customers. These solutions ensure that customers’ crypto assets, keys, and other related data are stored in a cold wallet environment in accordance with the principles of confidentiality, integrity, and accessibility.
At this point, the three fundamental principles of information security become crucial. The principle of confidentiality means that the related data can only be viewed in an authorized manner by authorized parties. The principle of integrity implies that the data must maintain the quality set by authorized users. Availability indicates that authorized users can access the relevant data in a timely manner within their permissions. Firms offering crypto custody services should clearly demonstrate how they ensure these principles and how they are applied throughout the lifecycle of crypto assets.
In terms of crypto assets, private keys allow users to access their digital assets and protect them against unauthorized access or transactions. If your private key falls into the hands of third parties due to fraud or theft, it means you’ve lost control over your digital assets. Hence, securely creating and storing private keys is critically important. Private keys and their backups should be kept separate and protected from internal and external attacks. This is where professional crypto custody solutions come into play. These solutions are used to reduce the risks associated with the confidentiality, accessibility, and integrity of private keys and their backups throughout their entire lifecycle.
Potential Risks
Let’s take a look at the main stages of the private key’s lifecycle and the potential risks present at each stage. The first stage is the key ceremony. There is a risk that our private keys may be viewed or copied without authorization during or after the key ceremony. There is also a risk of loss, theft, or damage to the private keys and backups during the storage process. Moreover, if the principle of job segregation related to the storage of private keys and backups is not clearly defined, or if a security framework suitable for risk appetite is not established, it’s another area of risk. If controls are not adequately designed for the approval and execution of digital asset transactions, the risk of unauthorized access and intervention may increase.
Therefore, you should take care to work with crypto asset custody companies that can offer a strong risk management and internal control structure. While in the financial world, where robust entities like banks operate, financial assets can be refunded in cases of mistakes or fraud, it’s important to keep in mind that there’s no such possibility in the crypto world.
