Why you should only use official wallets
Using an unofficial wallet is the shortest route to losing funds. The fake may look flawless, but inside it is a backdoor, key telemetry, altered signature prompts, or stealing a side phrase. Official wallets reduce these risks: they have verifiable distribution channels, signed builds, playable builds, public repositories, and an understandable update policy. Below is why this is critical and how to build a safe practice.
1) What threats are closed by the "official" approach
Fake apps and clones. Attackers publish a "twin wallet" in a store or imitation domain. Externally - the same UI, inside - theft of keys/signatures.
Harmful browser extensions. The plugin can replace the recipient's address, push deliberately dangerous transactions, or read a clipboard.
Substitution of updates. Unofficial unsigned builds and hash checks are easy to modify between releases.
Trojan SDK/Libraries. In the "forks" there are often traces of telemetry/keylogging, and in official projects - an audit of dependencies and a policy of fixes.
Domain phishing and ENS homographs. Similar characters in the domain/name lead to fake "wallet import" pages.
Supply-chain attacks. Load "finished build" from an unknown source = trust someone else's computer and build tools.
2) Signs of an official wallet
Verifiable installation sources: official site/repository, verified app stores, direct links from product documentation.
Assemblies digitally signed: desktop - signed. dmg/.exe/.AppImage; mobile - store verification; extensions - confirmed developer.
Public repository and release: changelog, version tags, hashes/Checksum (SHA256), sometimes playable builds.
Clear security model: does not store the sid on the server, emphasizes that the team will never ask for a sid phrase/private key.
Support and updates: regular fixes of vulnerabilities, clear EOL policy for older versions.
3) Why "official ≠ custodial" and what to choose
Official noncostodial wallet: you have the keys; the project is distributed from the channels being checked. This is the optimum for most: control + predictable renewal.
Official custodial service (exchange/bank): convenient UX, but the provider has the keys; Use only for onramp/offramp and low speed.
Hardware wallet from the official manufacturer: the best option for "cold"; it is important to verify the authenticity of the device and firmware.
4) Safe installation and upgrade practices
1. We go only from the "native" entry points. The site address is from your own bookmark, not from search/chat.
2. We check the domain and certificate. Typos, extra words, strange subdomains - a red flag.
3. Downloaded - checked signature/hash. Map the file hash to the one specified in the releases.
4. Mobile versions - only from official stores. Avoid. "Apk from the forum."
5. Extensions - from a verified developer profile. Check the number of installations, update history, description.
6. Updates - in place. Do not install the "pop-up banner update" on a third-party site; run the update in-app or from the official release page.
7. Never enter a sideframe for "update." The update does not require a sid - only recovery on a new device. Any request to enter sid - phishing.
5) Hardware wallets: what is considered "official"
Purchase from a manufacturer or authorized reseller. Do not take "from hand" and "printed."
Seals/initialization. The device must initialize with you and generate a new cid phrase on the device screen.
Signature and firmware. The update utility must verify the firmware signature; on screen - explicit version warnings.
Confirm addresses on the device screen. For shipments, check the address/amount on the hardware.
6) Extensions and web wallets: extra caution
Permissions. Minimize access to sites, prohibit auto-embedding on all domains.
Transaction signatures. Always read the text of the request: who calls which network, contract, amount, 'approve' or 'transfer'.
Address Book. Work with a whitelist of verified DApp and addresses; disable the extension when not in use.
Separate browser profiles. For defy/wallet - a separate profile without unnecessary plugins.
7) Four-eye mode and operational discipline
Double check before a major transaction. One initiates, the second confirms the details.
Test translation. Before a significant amount - $5- $20 and waiting for enrollment.
Journal of operations. Keep the date, network, address, hash, comment - helps in controversial situations.
Hot/cold separation. Fixed capital on the "cold," operating amounts - in the "hot" official wallet.
8) What an official wallet never does
Does not ask for a cid phrase or private key "for verification/gift/bonus/draw."
Does not send an "update" through random pop-up banners on other people's sites.
Does not require "install additional security profile" from an unknown source.
Does not impose a transfer of funds "to confirm ownership."
9) Checklist "I put/update the wallet"
- I went to my tab to the official site/repository.
- Downloaded from the verified store/release page; checked signature/hash.
- Did not enter a cid (except to restore to a new device).
- Extension - from a verified profile, with a release history.
- After installation, created an address book and enabled 2FA (if available).
- For "cold" - initialization of the hardware wallet with the generation of a new sid phrase on the device.
10) Mini-FAQ
Official = 100% safe? Nothing gives 100%. But the official channel dramatically reduces the risk of backdoor/counterfeiting and allows you to quickly receive vulnerability fixes.
Is it possible to use a fork for the sake of "convenient feature"? The risk is not justified for the means. If you really need it - only from the source code, with an audit of the code and on an "empty" wallet without capital.
Do I need to update right away? Critical updates - yes. Before updating, make sure that the cid phrase is backed up and check the assembly hash/signature.
And if the wallet is only on Telegram/web? Increased risk. Use verified official bots/webs, minimum balances and a separate profile/browser.
"Only the official wallet" is not about snobbery, but about controlling the chain of trust: verifiable sources, signed builds, transparent releases and predictable updates. Add to this a hardware storage wallet, a strict address book, test translations and the "we don't enter the sideframe anywhere" rule - and you will minimize the risk of loss of funds even with active work with crypto and DeFi.
