Types of wallets and their differences
In general, crypto wallets are divided into two types: custodial and non-custodial. The key difference is simple: it depends on who controls the private keys and, accordingly, access to the funds. We can develop either of these solutions.
Non-custodial
This is a wallet where private keys are held by the user, and the service has no control over them. This setup gives users full control, but it also has downsides: if the seed phrase or key is lost, access usually cannot be recovered.
- MobileIt’s a mobile app wallet. Convenient for daily operations.
- Web walletsThese type of wallets work through a browser or extension. They are often used for dApps.
- DesktopInstalled on a computer, suitable for more «work-focused» scenarios and better environment control.
Custodial
This is a wallet where users’ private keys are managed by a third party (for example, a platform or service). The advantage is that it’s easy to use, these wallets also have options for account recovery and user support. The downside is that the user is dependent on the rules and reliability of the custodian.
- Exchange walletsWallets within an exchange or broker, where keys are stored on the platform’s side.
- Custodial platform (product-level)Wallets that are integrated into your service, where keys and operations are managed by your infrastructure or a custody provider.
What we deliver for business clients
Custody model and security
We define who controls the keys and how access is managed: custodial or non-custodial model. This affects account recovery, risk profile, and requirements for protecting keys and operations.On-ramp and off-ramp
We integrate crypto purchase and sale for fiat directly into your product: no unnecessary steps and with a clear UX. Integration is usually done through a provider that handles part of the procedures and compliance checks.Transaction flow
We set up the full transaction lifecycle: signing, sending, fees, statuses, and history. It’s important that both the user and the operations team can always see what happened and check the operation status.Operational control
For custodial scenarios, we add manageability: roles, limits, withdrawal rules, monitoring, and support processes. This turns the wallet into a tool that can be safely operated without deep onboarding.Compliance and KYC/AML
If the product includes fiat rails or off-ramp, KYC checks and anti-fraud requirements are almost always required. We design this at the level of flows and integrations so that compliance doesn’t break the product after launch.Monetization and UX
We’ll develop an exchange module with the ability to set custom fees and account for income in financial accounting. We’ll also implement gas-free transactions for users to lower the entry barrier and improve the user experience.
We design and develop a wallet tailored to your business model. From a «universal wallet for everything» to a product-specific setup: who holds the keys, who signs transactions, how funds move, and where control and support are handled.

FAQ
What is the difference between a custodial and a non-custodial wallet?
In a custodial wallet, the service (provider/platform) manages the keys. In a non-custodial wallet, the keys are held by the user, and the service cannot recover access for them.
What to choose: custodial or non-custodial?
If you need account recovery, user support, and controlled operations, a custodial model is usually the best option. If you want full user control and dApp scenarios, go with a non-custodial one. In practice, the choice depends on product requirements and compliance.
Is it possible to enable login via email/socials without a seed phrase?
Yes. This is usually called embedded wallets : the wallet "lives" inside your application, and the user logs in using familiar methods (email/social). The keys can be managed using approaches like MPC/AA to remove the seed phrase from onboarding.
What is a smart-contract wallet and Account Abstraction (ERC-4337)?
Account Abstraction (ERC-4337) allows replacing standard EOAs with smart accounts controlled by smart contract logic. This enables features like gas fee sponsorship, multisig, social recovery, and transaction limits. This approach is the foundation of smart-contract wallets and provides a Web2-like UX in Web3 applications.
What is multisig and why does business need it?
Multisig is a wallet where multiple signatures are required to execute a transaction (for example, 2-of-3). It is commonly used for corporate funds, treasuries, funds management, and scenarios where control and separation of responsibility are important.
What are on-ramp and off-ramp, and can they be integrated into a wallet?
On-ramp/off-ramp are services that allow users to buy crypto with fiat and convert crypto back to fiat. They can be integrated into a wallet via providers, but requirements heavily depend on jurisdiction and compliance.
