Coinomi Wallet review
One of the oldest multichain wallets, self-custody with huge coin support and strong privacy. Two things weigh it down: a 2019 seed-exposure bug and closed-source code.
Coinomi Wallet is Coinomi’s multichain self-custody wallet (free). A veteran self-custody wallet that does a lot right: keys stay on your device, the coin coverage is enormous, privacy is a genuine priority with no KYC and IP anonymization, and it runs on mobile and desktop with built-in swaps and staking. Its app-store ratings are strong. What holds the score down is trust history. In 2019 its desktop app sent a recovery phrase typed into the restore field to Google's spellcheck service in clear text, a serious design defect that Coinomi patched within hours and says caused no proven loss, but its combative, victim-blaming response was a bad look. And the wallet is closed source, so its code cannot be independently audited. Capable and broad, but not the wallet for the security-first.
It scores 6.8 out of 10 on our fixed 40-point standard, and is our best long-running multichain wallet, weighed on security, ease of use, supported assets, value and recovery. Strengths: Very broad multichain coin support; Genuine self-custody with strong privacy; Long operating history since 2014. Trade-offs: The 2019 desktop seed-exposure bug and combative response; Closed source, so code cannot be independently audited; Fake clone apps make safe downloading important.

Coinomi is one of the longest-running multichain wallets, live since 2014. This Coinomi Wallet review holds two things together: it is broad, private and genuinely self-custody, and it also carries the most-cited security incident of any wallet in our roundup. Both belong in an honest review.

Self-custody, broad and private
Coinomi is non-custodial: your keys never leave your device, and there is no account or KYC to use it. It runs on iOS, Android and desktop for Windows, macOS and Linux, and it supports a very large list of coins and tokens across dozens of blockchains, with a built-in exchange through partners, staking including cold staking, a dApp browser and 30-plus languages. Recovery uses a standard recovery phrase. For privacy and sheer coverage, it is strong, which is why it retained a following for so long.
Coins, exchange and fees
The draw for most users is breadth of crypto: Coinomi holds Bitcoin, Ethereum and thousands of tokens across more than 100 blockchains, and you can add tokens manually, so a diverse portfolio lives in one app. Within the app the built-in exchange lets you swap crypto through partners without moving funds to a centralized venue, and staking, including cold staking, earns yield on supported coins. On fees, sending and receiving cost only the network fee, and the swap or trading cost is baked into the quoted exchange rate rather than shown as a separate line, so compare the amount you receive before confirming. There is no wallet subscription, and no fee simply to hold your crypto. On security posture the private keys stay on your device behind a password and biometric lock, and Coinomi states no wallet has been hacked since 2014, though as a hot wallet it still carries the usual online exposure.
The 2019 spellcheck incident
This is the crux of any Coinomi Wallet review. In February 2019 a researcher showed that Coinomi's desktop app, when you typed your recovery phrase into the restore field, sent that text to Google's spellcheck service over the internet, because spellchecking was on by default in the underlying framework. Seed material leaving the device in clear text is exactly what a wallet must never do. Coinomi's defense was that the requests were encrypted, carried no API key so Google rejected them, and were never stored, and that only the desktop app was affected, not mobile. It patched the bug within hours. No fund loss was ever independently proven, though the researcher claimed a large loss, which Coinomi disputed while publicly accusing him of extortion. Take it as a real, serious defect, quickly fixed, wrapped in an ugly public fight, and the main reason the score sits at 6.8.
Closed source
Coinomi was open source in its early days but went closed source around 2018, a move it attributes to scammers cloning its code into malicious fake wallets. Whatever the reason, the result is that the current code cannot be independently audited by the community, which for a wallet is a meaningful drawback and compounds the trust question from 2019. Because fake Coinomi clones exist, downloading only from the official site and app stores matters more here than usual.
Coinomi Wallet vs the alternatives
Against Exodus and Trust Wallet, Coinomi matches broad coin support but both rivals have cleaner records and Trust is partly open source. Against Guarda, another veteran multichain wallet, the two are close, with Guarda's non-standard backup weighed against Coinomi's 2019 history. For open-source assurance, Rainbow or a hardware wallet is the safer route.
| Coinomi | Exodus | Trust Wallet | Guarda | |
|---|---|---|---|---|
| Coins | Very broad | Thousands | 100+ chains | 1M+ tokens |
| Open source | No | No | Partly | Partial |
| Backup | Seed phrase | Seed phrase | Seed phrase | Encrypted file |
| Notable | 2019 seed bug | Clean record | Clean record | Card fees |
| Score | 6.8 | 7.9 | 7.8 | 7.0 |

Price and value
Coinomi is free to download and use, and sending or receiving costs only network gas. It earns from the built-in exchange, whose cost sits inside the quoted rate, so a heavy trader is cheaper on a dedicated venue. For a multi-coin holder who values privacy and a long track record, the core wallet is good value; the value case weakens if open-source, auditable code is something you insist on.
Who should buy Coinomi Wallet
Coinomi still delivers for someone who wants broad coin support and privacy from a wallet with a long history, and who weighs the 2019 episode as the past it now is. It is the wrong pick if open-source, independently auditable code is a must, in which case Rainbow, a partly open wallet like Trust Wallet, or a hardware wallet is the safer choice.

Coinomi Wallet FAQ
Is Coinomi safe to use?
It is genuine self-custody with keys on your device and has no confirmed breach of its systems. The caveats are its 2019 desktop bug that briefly exposed recovery phrases to a spellcheck service, since patched, and that its code is closed source and cannot be independently audited. Weigh those against its broad coverage.
What was the Coinomi 2019 bug?
In February 2019 Coinomi's desktop app sent a recovery phrase typed into the restore field to Google's spellcheck service in clear text, because spellchecking was on by default. Only desktop was affected. Coinomi patched it within hours and says the data was encrypted, rejected by Google and never stored, with no proven fund loss.
Is Coinomi open source?
No. It was open source early on but went closed source around 2018, which Coinomi attributes to scammers cloning its code into fake wallets. The result is that its current code cannot be independently reviewed.
Is Coinomi non-custodial?
Yes. Your private keys stay on your device and Coinomi does not hold your funds. It is a hot wallet, so it carries the usual online exposure of software wallets.
How many coins does Coinomi support?
A very large number. Coinomi's own figure is more than 10,000 tokens across 50-plus blockchains, with review sites citing different counts. Either way, coverage is one of its main strengths.
Does Coinomi charge fees?
It is free to send and receive, paying only the network fee. In-app swaps carry the exchange partner's fee, commonly around a quarter to half a percent, plus spread.
How do I avoid fake Coinomi apps?
Only download from the official coinomi.com links or the official app-store listings. Fake clone apps are a known risk, and are the reason Coinomi gives for going closed source.
How is Coinomi rated?
Well, on the surface: about 4.6 out of 5 on both the App Store and Google Play, and 4.5 on Trustpilot. The security history is the reason to look past the star rating.
Is the Coinomi wallet safe in 2026?
This coinomi wallet security review keeps the score modest: the 2019 desktop spellcheck bug that briefly exposed recovery phrases, since patched, plus closed-source code, are real trust concerns. A coinomi wallet review 2026 verdict is that its broad coverage and privacy are strong, but security-first users have better options.
