The growth in the use of cryptocurrencies in business is one of the most notable trends in the digital economy. More and more companies are integrating crypto payments into their payment systems: from online retail to B2B services.
According to analysts' estimates, by the end of 2025, the daily volume of cryptocurrency transactions will reach $300 billion, three times more than at the end of 2024.
Along with the popularity of crypto payments, the need for reliable ways to store digital assets is also growing. Losing private keys or having your wallet hacked can result in millions in losses. Therefore, choosing the right type of crypto wallet is a critical task for any business working with cryptocurrencies. Let's compare the three main types of wallets – hot wallets, cold wallets, and custodial solutions – in terms of security, ease of use, service cost, scalability, and regulatory compliance. We will analyse which type of wallet is optimal for daily payments and which is optimal for long-term storage of reserves. We will also look at the role of 0xProcessing as a crypto payment processor for business, providing secure integration of all types of wallets.
What are business wallets for cryptocurrencies?
A business wallet for cryptocurrencies is a specialised solution for companies to store, receive and send crypto assets. Unlike consumer wallets, it meets the specific requirements of the corporate sector.
- Secure storage of reserves;
- Processing crypto payments for business;
- Employee access management (role-based model);
- Compliance with AML/KYC and other regulatory requirements;
- Integration with accounting and ERP systems;
- Auditing and reporting for tax authorities.
Standard wallets (e.g., mobile or browser-based) do not provide role-based access, adequate protection against internal threats, APIs for integration with accounting systems, tools for corporate auditing, or regulatory compliance.
Hot Wallets: Speed vs. Risk
Hot crypto wallets are online wallets with a constant connection to the network. They provide instant access to funds and easy integration with payment systems.
Examples of hot wallets include web interfaces (exchange wallets), mobile apps with online access, and API solutions for payment automation.
Advantages of hot wallets:
- Instant access to funds – ideal for processing current payments;
- Convenience for accepting crypto payments for business – easy to integrate into online stores and services;
- Easy setup and use – no special technical knowledge required;
- Support for bulk payments – hundreds of transactions can be sent automatically;
- Compatibility with crypto payment processors for business – for example, with 0xProcessing.
Use cases: daily transactions with customers, processing small payments (up to £10,000), testing new crypto services, integrating with payment gateways, and working with high-turnover assets.

Disadvantages of hot wallets:
- Vulnerability to hacker attacks – online connection makes them a target;
- Dependence on the service provider – server failures can block access to funds;
- Risk of losing funds if the device or account is hacked;
- Limited protection against phishing – employees may accidentally disclose keys.
Cold Wallets: Security Above All
Cold wallets are offline solutions without a constant internet connection. They are considered the most reliable way to store crypto assets.
Types of cold wallets:
- Hardware wallets (Ledger, Trezor, SafePal) – physical devices storing keys in an isolated environment;
- Multi-signature storage – multiple keys required to confirm transactions;
- Air-gapped solutions – computers never connected to the network.
Advantages:
- Maximum protection against online threats;
- Full control over private keys;
- Resistance to phishing and hacker attacks;
- Protection against unauthorised access;
- Compliance with strict regulatory requirements for asset storage.
Disadvantages:
- Slow transaction processing – manual confirmation and device connection required;
- Complexity of mass use – inconvenient for frequent payments;
- Risk of physical loss or damage;
- Need to train staff;
- High initial costs for purchasing equipment.
Use cases: storing large reserves (over £100,000), long-term investments, backups, funds not requiring immediate access, complying with capital reserve requirements. Cold wallets are relevant for exchanges, investment funds, large retailers, and companies handling regulated assets.
Custodial Wallets: Convenience Through Control
Custodial wallets are solutions where private keys are stored by a third party: an exchange, payment provider, or specialised custodian. Examples include Coinbase Custody, BitGo, and Fidelity Digital Assets.
Advantages:
- Ease of management – no technical knowledge required;
- Access recovery in case of loss;
- Built-in AML/KYC support;
- Integration with crypto payment processor for business;
- Fund insurance – some providers cover theft risks;
- Compliance with regulatory requirements – custodians undergo audits and obtain licences.
Disadvantages:
- Dependence on the provider – funds can be frozen;
- Risk of custodian bankruptcy;
- Less transparency of operations – private keys not controlled by the company;
- Service fees – usually 0.1–0.5% of transaction volume;
- Withdrawal restrictions.
Use cases: companies without technical resources, regulated assets, quick start without complex setups, integration with payment gateways, jurisdictions with strict data storage requirements.
