What is a crypto wallet, and how does it work?
A crypto wallet is a digital tool that stores your private and public keys, enabling you to send, receive, and manage cryptocurrencies on blockchain networks.
While it doesn’t hold crypto directly, it reflects your balance and activity, much like a bank account.
There are two primary wallet categories: custodial wallets and non-custodial wallets.
What is a custodial wallet?
A custodial wallet is a type of digital wallet where a user or a third party, typically an exchange or regulated financial institution, manages and stores private keys on behalf of the user.
This model simplifies access and recovery but shifts control away from the user..
Benefits and limitations of custodial wallets
| Advantages | Challenges |
|---|---|
| User-friendly: Easy onboarding and intuitive interface. Integrated services: Built-in trading, buying, and fiat conversion. Regulatory compliance: Easier adherence to KYC/AML regulations. | Users don’t directly control their private keys. Centralized security risks are vulnerable to breaches (e.g., Mt. Gox, Bitfinex hacks). Potential downtime and limited access during service outages. |
The ideal use cases for custodial wallets
Custodial wallets are ideal for startups, fintech platforms, and regulated institutions that prioritize convenience, compliance, and streamlined user experiences.
Best examples of custodial wallets:
What is a non-custodial wallet?
A non-custodial wallet, also known as a self-custodial wallet, gives users full control over their private keys, eliminating reliance on third-party providers.
The keys are stored securely on the user’s own device, ensuring true ownership of digital assets.
Pros and cons of self-custodial wallets
| Benefits | Challenges |
|---|---|
| Full control over digital assets: Direct access to blockchain transactions. Enhanced security: Eliminates third-party risk of hacks. Greater privacy: No mandatory identity verification. Compatible with DeFi and Web3 services. | Higher responsibility: Losing keys means irreversible loss of funds. Often requires technical understanding or careful UX design. |
Who should choose non-custodial wallets?
Non-custodial wallets are ideal for blockchain-based apps, decentralized finance (DeFi) platforms, and fintech startups seeking to offer self-custody and true financial autonomy.

Security and regulatory factors of crypto wallets
If you’re considering building a crypto wallet, it’s essential to look beyond core features and consider both security and regulatory compliance.
The requirements differ significantly between custodial and non-custodial models, each carrying distinct risks and responsibilities. Overlooking these factors can lead to security breaches or compliance violations.
In the sections below, we break down the most common risks associated with each type of wallet and explore strategies to mitigate them effectively.
Custodial wallet vulnerabilities
Custodial wallets have been frequent targets of cyberattacks due to the centralized storage of private keys. This centralized model has led to some of the most high-profile security breaches in crypto history.
Below are key incidents that highlight the inherent risks of custodial wallet solutions.
- Mt. Gox (2014): $450M Bitcoin loss.
- Bitfinex (2016): Around 120,000 BTC (~$72M) stolen.
- Coincheck (2018): $530M compromised due to hot wallet vulnerabilities
How to protect custodial wallets from security risks
- Multi-signature authentication: Prevents single points of failure by requiring multiple approvals for transactions.
- Cold storage protocols: Keep the majority of funds offline to minimize exposure to online threats and hacks.
- AI-powered fraud detection: Leverages machine learning to identify suspicious behavior and flag anomalies in real time.
- Security certifications: Achieving certifications like SOC 2 or ISO 27001 helps validate the organization’s commitment to data protection and security standards.
Top challenges of using non-custodial wallets
Non-custodial wallets offer stronger asset control and security, but they also come with technical and usability challenges.
From key management to onboarding complexity, here are the key trade-offs to consider.
Key storage and recovery
With non-custodial wallets, users maintain control of their keys, providing better security and control. However, that also leaves users open to potentially irreversible losses if those keys are lost or compromised.
How to secure private key handling
- Safe storage of private keys: On-device key storage solutions like Apple Keychain (iOS) or Android Keystore allow keys to be encrypted and stored in secure system-level modules, reducing attack surfaces.
- Key recovery mechanisms: Modern approaches like Stellar’s SEP-30 offer simplified flows and can enhance usability.
Evolving regulatory landscape
As global regulators tighten oversight, both custodial and non-custodial wallets face increasing scrutiny, but the impact varies based on how the wallet is structured.
Custodial wallet regulation
Custodial wallets, in particular, are often classified as Money Services Businesses (MSBs) under U.S. law.
This classification requires registration with the Financial Crimes Enforcement Network (FinCEN) and adherence to strict compliance protocols.
Key compliance requirements for custodial wallets
- Know Your Customer (KYC): Verifying user identities to prevent fraud and illicit activity.
- Anti-Money Laundering (AML) controls: Monitoring transactions and reporting suspicious activity.
- Data protection regulations: Ensuring secure storage and handling of user information, like Suspicious Activity Reports (SARs) and Currency Transaction Reports (CTRs).
- Licensing and reporting obligations: Meeting state-level and federal regulatory standards.
Non-custodial wallets regulation
Meanwhile, non-custodial wallets generally fall outside FinCEN’s MSB designation, as they don’t hold or transmit user funds.
However, this could change as regulators increasingly examine decentralized technologies that still offer UI layers or added services.
Key regulatory developments to monitor
To stay compliant as the landscape shifts, businesses operating or developing wallet solutions should actively track:
- Any proposed legislation targeting self-hosted wallets and peer-to-peer transactions.
- Discussions around applying the Bank Secrecy Act (BSA) to developers or front-end providers.
- Evolving IRS guidance on wallet-related tax reporting, especially where staking or DeFi is involved.
- Data privacy obligations, especially when collecting metadata or user behavior data, even if not personally identifiable.
