Cryptocurrency wallets have evolved significantly since the early days of Bitcoin, when private keys were stored in a simple file named _wallet.dat. Today, users demand more than just storage—they seek security, versatility, and seamless integration with the broader Web3 ecosystem. In this comprehensive review, we’ll explore Coinomi, a non-custodial crypto wallet known for its wide asset support and user-friendly design.
Whether you're managing Bitcoin, Ethereum, ERC-20 tokens, or NFTs, Coinomi aims to be your all-in-one solution. But does it live up to the hype? Let’s dive into the features, security, usability, and limitations of this long-standing wallet.
What Is Coinomi?
Launched in 2014, Coinomi has built a reputation as a reliable and feature-rich cryptocurrency wallet. It supports over 1,770 blockchain assets, including major cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH), as well as hundreds of tokens based on standards like ERC-20, BEP-2, and TRC-10. This makes it an excellent choice for users managing a diverse crypto portfolio.
As a non-custodial wallet, Coinomi ensures that you retain full control over your private keys—meaning no third party can access or freeze your funds. The platform also boasts a clean security record, with no reported breaches since its inception (as of August 2024).
Beyond basic storage, Coinomi integrates advanced features such as Digi-ID, FIO Protocol, and Unstoppable Domains, enhancing both security and user experience. These tools allow for blockchain-based identity verification and human-readable addresses, reducing the risk of sending funds to incorrect addresses.

Key Features of Coinomi Wallet
Supports a Wide Range of Cryptocurrencies
One of Coinomi’s standout strengths is its extensive multi-asset support. From Bitcoin and Ethereum to lesser-known altcoins and stablecoins like Tether (USDT), the wallet enables users to store and manage a broad spectrum of digital assets in one place.
It also supports NFTs based on the ERC-721 standard, allowing collectors to view and manage their digital art and collectibles directly within the app. For DeFi enthusiasts, this means easier access to decentralized exchanges (DEXs), lending platforms, and yield farming opportunities.
The wallet continuously evaluates and adds new tokens and blockchains, ensuring users stay aligned with market trends. While availability may vary by region—especially for fiat on-ramps—Coinomi remains accessible to users worldwide, including those in the United Kingdom.
Built-In Exchange and Crypto Purchasing
Coinomi includes a built-in exchange feature powered by ShapeShift, enabling users to swap between cryptocurrencies without leaving the app. This not only streamlines trading but also enhances security by keeping funds under your control at all times.
Additionally, users can buy crypto with fiat currencies like USD or EUR through third-party integrations such as MoonPay or Simplex. Although direct fiat deposits aren't supported, this functionality offers a convenient entry point for newcomers looking to convert traditional money into digital assets.
Cold Staking Capabilities
For users interested in earning passive income, Coinomi supports cold staking—a rare feature among mobile wallets. With cold staking, you can earn rewards on assets like Callisto (CLO) without keeping your device online 24/7.
This combines the benefits of staking with enhanced security, as your private keys remain offline while still participating in network validation. It’s an ideal option for long-term holders who want to maximize returns without compromising safety.
Integrated dApp Browser and Web3 Access
Coinomi comes equipped with a built-in dApp browser, giving users direct access to decentralized applications across various blockchains. From DeFi platforms like Uniswap to NFT marketplaces and blockchain games, you can interact with the full Web3 ecosystem from within the wallet.
This integration eliminates the need for external browsers or additional apps, reducing exposure to phishing attacks and malicious sites. Whether you're lending crypto, swapping tokens, or minting NFTs, Coinomi provides a secure gateway to decentralized services.
Security Measures in Coinomi
Security is paramount in any crypto wallet, and Coinomi delivers robust protection through several layers:
- 24-word recovery phrase: Generated during setup, this seed phrase allows full wallet recovery if your device is lost or damaged.
- Biometric authentication: Supports fingerprint and facial recognition for quick, secure access.
- Local key storage: Private keys are stored only on your device—not on Coinomi’s servers—ensuring true self-custody.
- No KYC required: Users aren’t asked to provide personal identification, preserving privacy.
- IP anonymization: Helps prevent tracking and enhances anonymity during transactions.
Despite these strong measures, users bear full responsibility for safeguarding their recovery phrase. Losing it means permanent loss of funds—a critical consideration for new users.
Native SegWit Support for Efficient Bitcoin Transactions
Coinomi supports Segregated Witness (SegWit), a Bitcoin protocol upgrade that improves transaction efficiency. By separating signature data from transaction data, SegWit increases block capacity, leading to:
- Faster confirmation times
- Lower transaction fees
- Better scalability
This also future-proofs the wallet for upgrades like the Lightning Network. For frequent Bitcoin users, native SegWit support translates into cost savings and improved performance—especially during periods of high network congestion.
Limitations of Coinomi Wallet
While Coinomi excels in many areas, it has notable drawbacks worth considering.
No Hardware Wallet Integration
Unlike some competitors, Coinomi does not support integration with hardware wallets like Ledger or Trezor. This means users cannot leverage cold storage solutions for added security—a significant downside for those prioritizing maximum asset protection.
However, strong software-level security features—such as encrypted backups and biometric login—can help mitigate this limitation when combined with best practices like secure seed storage.
Closed-Source Code
Another concern is that Coinomi is no longer open source. Previously available for public audit, the shift to closed-source code raises transparency issues. Open-source wallets allow independent developers to verify code integrity, detect vulnerabilities, and ensure there are no backdoors.
While Coinomi maintains a solid security track record, the lack of public scrutiny may deter privacy-conscious users who value full transparency.

Coinomi Wallet Fees
The good news? Coinomi does not charge any fees for sending or receiving cryptocurrencies. All transactions are free at the wallet level.
However, users must still pay network transaction fees, which vary depending on blockchain congestion and chosen priority level. For example:
- High-priority Bitcoin transactions cost more but confirm faster
- Ethereum gas fees fluctuate based on network demand
When using third-party services—like buying crypto or swapping tokens—additional fees apply from providers like MoonPay or ShapeShift. These are clearly displayed before confirmation, helping users make informed decisions.
How to Set Up and Use Coinomi
Mobile Setup (Android & iOS)
- Download the app from Google Play, App Store, or APK (for Android).
- Open the app and select Create a New Wallet.
- Choose encryption level (recommended: Most Secure).
- Set a strong password (minimum 10 characters with symbols).
- Select desired cryptocurrencies to add.
- Agree to Terms of Service.
After setup, back up your 24-word recovery phrase immediately.
Desktop Version
Although Coinomi is working on a major desktop update, an older version remains available for Windows, macOS, and Linux. Setup follows similar steps:
- Download and install the desktop app.
- Click Create a New Wallet.
- Write down and securely store your 24-word recovery phrase.
- Confirm the phrase in order.
- Set a strong password.
- Select preferred cryptocurrencies.
- Accept Terms of Service.
Note: The updated desktop version promises improved functionality and enhanced security—recommended once released.
How to Back Up Your Coinomi Wallet
Backing up is essential:
- Open the app and tap “Wallet not backed up.”
- Enter password and authenticate via biometrics.
- Copy the 24-word recovery phrase.
- Store it offline (e.g., written on paper in a safe).
- Confirm the phrase by selecting words in order.
- Optionally change your password.
Never share or digitize your seed phrase—doing so risks theft.
