How Does Crypto Custody Work?

Have you ever thought about how cryptocurrencies are stored and managed securely?

The answer is quite simple. It is through the cryptocurrency custody solutions. They are the ones that securely store the private keys that provide access to the digital assets. 

With the rise in cryptocurrency adoption, crypto custody has become one of the essential concepts for securely managing digital currencies.

What is Crypto Custody?

Crypto custody is the storage and management of private keys that prove ownership of digital assets and provide access to your crypto assets. These crypto custody solutions securely store and manage private keys on behalf of individuals, institutions, or businesses. 

Adopting a secure crypto custody approach helps you to protect your funds from cyberattacks and unauthorized access. 

3 Types of Crypto Custodial Models 

Crypto users often get confused about who manages the private keys and who authorizes the cryptocurrency transactions in crypto custody solutions. Let me explain to you in detail. 

Generally, crypto custodial models are of 3 different types. It includes, 

• Self-custodial model
• Third-party custodial model 
• Shared control custodial model

Let's look into them in detail. 

1. Self-Custodial Model

The self-custodial model provides individuals and organizations with complete control over their private keys. That is, the cryptocurrency owners will be fully responsible for storing and managing their private keys. 

This model eliminates the need for an intermediary. 

Though the self-custodial model provides complete custody over their private keys, the loss of the seed phrase, key recovery method, or a fault in the system can make the crypto owner lose all their digital funds. 

This type of digital asset custody model can be suitable for businesses that follow strict security habits. 

2. Third-Party Custodial Model 

The third-party custodial model involves a third-party organization that takes on the processes, such as private key generation, asset storage, and transaction authorization. 

Cryptocurrency users surrender their private keys to these third-party custodians, where they store these keys in their infrastructure. The storage infrastructure is governed by various security measures, such as identity verifications and withdrawal limits, that help in preventing unauthorized logins. 

Here, the responsibility of managing the private keys solely depends on the third-party crypto custodian rather than the crypto owner itself. So, it is essential for the crypto custodian firm to undergo regular security audits to maintain the security of the infrastructure. 

3. Shared Control Custodial Model 

The shared control custodial model is a type where the private keys are under the control of multiple parties. This model involves three approaches that include the following. 

• Multi-signature wallet - This approach requires multiple keys for signing a transaction. 
• Hybrid model - In this approach, both the custodian and crypto owner will hold a key each. 
• Institutional Variation - Multiple organizations join together and run an in-house crypto custody or hire a subcustodian to manage the private keys. 

This model brings in more security as it requires multiple approvals to process the funds. If one party fails, the other one can protect the funds without approving the transaction. 

Technologies Behind the Secure Crypto Custody 

There are a lot of advanced technologies that help crypto users to store and manage their digital currencies securely. Let’s have a look at it in detail. 

3 Best Types to Manage Crypto Exposure 

Usually, some crypto owners might access cryptocurrencies frequently, and some might not. So, based on the frequency of cryptocurrency usage and to manage the crypto exposure,  the crypto custodians have categorized the storage model into 3 types. 

Model Type	Description	Suitable For
Cold Storage	Completely keeps the private keys offline, which are stored in hardware or encrypted devices.	Best for long-term storage
Warm Storage	Uses hardened servers with strict access rules	Suitable for quicker access without exposing private keys
Hot Storage	Completely keeps the private keys online	Suitable for frequent crypto usage

Hardware Security Modules (HSMs)

These types of technologies are used when custodians require high speed and strong protection for their private keys. 

These modules store private keys inside a hardware system that is capable of detecting unauthorized logins. 

Multi-Signature Wallets 

Multi-signature wallets require multiple independent signatures for approving a transaction. The signatures are spread across multiple devices, where a single mistake cannot lead to loss of funds. 

Multi-Party Computation 

The MPC system will generate private key shares rather than generating a single private key as a whole. These keys are shared across multiple devices, and when a transaction needs an approval, the devices together produce a valid one. 

What are the Benefits of Crypto Custody?

Digital asset custody models offer various benefits. Let’s look into them one by one. 

• Crypto custody focuses on building a highly secure private key storage infrastructure that makes it easy for individuals and institutions to store their private keys securely. 
• Digital assets custody models boost the operational efficiency and minimize the efforts in managing their private keys. 
• Crypto custody providers provide greater security models, such as multi-party computation and HSMs.
• These models can reduce risks in many ways, which include transaction approval policies, deposit address authentication, and recovery support.
• Advanced crypto custody technologies like MPC offer both speed and security together, allowing users to access their cryptocurrencies without worrying about security. 
• Adopting modern crypto custody solutions has enabled crypto users to manage their digital assets more efficiently and also maintain security without sacrificing flexibility. 

Risk Control Measures for Crypto Custody Solutions 

Though crypto custody providers follow a wide range of security measures to protect the private keys from hacks or unauthorized access, here are some additional risk control measures a digital asset custody provider can follow. 

1. Storing cold wallets in a highly secure environment with biometric access, similar to a bank vault, can enhance security measures. 
2. Continuous monitoring, penetrating testing, and integrating an unauthorized entry detection system can help in preventing security breaches. 
3. Providing insurance for cyber thefts and hot wallet breaches can be a good risk control approach. 
4. Following strict legal compliance for asset segregation, audit trails, and client protection is an essential risk control method that should be adopted by the cryptocurrency custody providers. 

How can Businesses Select the Right Crypto Custody Solution?

Choosing the right cryptocurrency custody solution for safeguarding your private keys is a must. Select them by keeping these 4 things in mind. 

1. The type of business you run 
2. Decide whether you want a self or third-party custodial approach
3. Based on Security Infrastructure
4. Based on its scalability 

Let’s look into them in detail. 

Type of Business You Run

The usage of cryptocurrencies will differ based on the type of your business. In some cases, businesses like crypto exchanges may frequently move funds, but businesses that use crypto only as an investment plan might hold the asset still for a longer term. 

So, clearly understand your needs and select the most suitable crypto custody solution. 

Decide Whether You Want a Self or Third-party Custodial Approach.

If you want full control over your assets, opt for a self-custody approach, where you will be required to monitor, maintain, and secure your private keys. Choose this model only if you have technical expertise in security protocols. 

On the other hand, opting for a third-party crypto custodian will eliminate the need for you to handle private keys on your own. These third-party crypto custody providers will handle all the responsibilities from asset management to transaction approvals. 

Based on Security Infrastructure

Have a detailed look at the cryptocurrency custody providers’ security infrastructure. Check on how they generate and store private keys, their transaction approval process, recovery approaches, and insurance coverage. 

Also, check how often they perform security audits. 

Based on its Scalability 

Digital currency requirements can change gradually as the business grows. So, choosing a flexible custody solution can help you scale up when your needs increase. This will help you to adapt without any discrepancies. 

Future of Cryptocurrency Custody 

The cryptocurrency industry is growing rapidly, and secure custody solutions are becoming the most important ones for both individual and institutional crypto investors. It plays a significant role in protecting and managing the digital assets. 

Compared to traditional cryptocurrency custody solutions, the modern solutions are becoming more secure and efficient. This is due to the advancements in technology that help in securing the private keys from cyberattacks. 

Also, crypto custody providers are improving their regulatory standards to enhance the security protocols for preventing unauthorized access to private keys. 

Last but not least, the involvement of traditional finance organizations is boosting the way cryptocurrency custody works.
