What is Coinomi?
Coinomi is a multi-currency software wallet founded in 2014, supporting more than 10,000 digital assets across over 50 blockchains, including Bitcoin, Ethereum, and Solana. It provides self-custody by generating and storing private keys directly on user devices.
Company background and operations
Coinomi was co-founded by CEO George Kimionis and Giannis Jegutanis. Coinomi also runs an investment arm, Coinomi Ventures, which backs early-stage blockchain startups from initial concept through Series A stages.
Custody and key features
Coinomi uses standard BIP44 hierarchical deterministic architecture, meaning users manage their entire portfolio through a single master recovery phrase. Supported platforms include Android, iOS, Windows, macOS, and Linux. The wallet connects to third-party providers such as Changelly, Nexchange, and HoudiniSwap for built-in token exchanges, while fiat purchases are facilitated by payment processors like Simplex and Onramper. Advanced users can connect directly to their own Bitcoin full nodes, manage UTXO coin selection, and access decentralized applications using WalletConnect or the built-in browser.
Fees and platform availability
Coinomi does not charge platform fees for holding, sending, or receiving cryptocurrencies. Users pay network miner or validator fees, with options for custom pricing and dynamic calculation. The software is free to download globally without identity verification or registration requirements. However, third-party swap services and fiat processors integrated into the application set their own variable fees and may impose KYC checks depending on the transaction type.
Security track record and limitations
In February 2019, a vulnerability was uncovered in Coinomi desktop version 1.0.4, where seed phrases entered during restoration were transmitted in clear text inside HTTPS requests to Google's spell check API, leading to an alleged 17 BTC theft before Coinomi issued a patch. Additionally, Coinomi lacks hardware wallet integration, meaning private keys remain bound to internet-connected devices.

Good
Coinomi delivers extensive multi-chain asset support and privacy features but lacks hardware wallet integration.
Coinomi is a self-custodial software wallet operating since 2014, founded by George Kimionis and Giannis Jegutanis. It is built to store, send, swap, and manage private keys across more than 50 distinct blockchains and over 10,000 tokens. The wallet runs on Android, iOS, Windows, macOS, and Linux. Users synchronize their portfolios across these devices through standard hierarchical deterministic recovery phrases.
Key strengths center on privacy and UTXO management. Coinomi requires no identity verification or sign-up procedure. Its servers anonymize requests by hiding user IP addresses, and the software supports custom miner fees alongside native SegWit address formats. For Bitcoin and other UTXO-based chains, the application includes dusting attack protection and coin-sweeping capabilities directly from raw private keys. Users can also connect the interface directly to their own full Bitcoin nodes.
The product exhibits notable trade-offs that limit its appeal for cold-storage security. Coinomi provides no hardware wallet support for devices like Ledger or Trezor, leaving private keys in a software-wallet environment. In 2019, a vulnerability in its desktop version transmitted seed phrases in unencrypted form to Google's spell check API during wallet imports, which allegedly contributed to an asset theft before the issue was patched.
In-app asset conversions and fiat on-ramps rely on third-party aggregators and partners including Changelly, Simplex, and Onramper, which can introduce external processing fees. Coinomi is suited to individuals seeking a multi-platform, no-KYC interface for diverse altcoins and legacy tokens, but users demanding cold storage safeguards should look elsewhere.
