I have used it for a couple years with no problem. The devs are active and add more swap pairs on a regular basis. Best digital wallet I have ever used. ### 4/5 — Please Allow Hiding Any Wallet *2022-07-25, version 4.22.1* This wallet is absolutely amazing, Klever does a fantastic job with their wallet and exchange, and now layer-1, but my only complaint is please allow us to hide any wallet. If I import a 2nd wallet I can't hide the original of a token's wallet that I'm not using. Please allow hiding of any wallet, and I would say this is in the top 3 wallet apps. ### 5/5 — Secure and easy *2022-06-25, version 4.19.3* The wallet is secure and makes crypto easy. I use it all the time and have never had any problems. Definitely recommend ### 5/5 — Best project yet *2022-06-09, version 4.17.0* Klever is a low hype project that delivers on their promises. I’ve been in crypto for a little bit and they are one of the ones doing it right, in my opinion. ### 5/5 — Great non-custodial wallet and growing ecosystem! *2022-06-09, version 4.17.0* The Klever wallet has been my primary wallet for the last two years. It supports numerous blockchains, has a built-in non-KYC token swap, and dapp browser allowing web3 access to various crypto protocols. ### 5/5 — Preferred wallet *2022-03-25, version 4.12.0* This is my preferred wallet by far. The ecosystem that is being built around it is amazing and comprehensive, designed to make using crypto easy. Highly recommend . ### 1/5 — Unreliable and sketchy *2022-01-08, version 4.8.0* Not only does the app not properly inform you on how to use its functions, they take money from your investments with no prior prompt leaving you to figure out by the value of your wallet going down. When buying crypto from here, let’s say for $50, they without any warning or prior information, only put $32-$36 in your wallet, taking some of your investment. Though I can understand why that would happen, however they even go so far as to, when you are only transferring crypto to another crypto, they DONT PROPERLY CONVERT IT. Taking some of your investment. Finally making this whole thing seem even more like a simple scam, there are times they don’t let you withdraw anything from some of their stocks, and worst of all. You are unable, that’s right unable to pull out the money you invested into your crypto using Klever or Klever wallet. You need do download a third party app….. don’t invest here, there are better made, and more simple apps that actually work. ### 5/5 — Easy Wallet to use *2021-12-27, version 4.8.0* Klever has created a very user friendly wallet. I’ve referred Klever wallet to people new to crypto that are afraid of moving their money around and everyone so far has been more than happy with the UI and the easiness to swap, buy or stake. ### 5/5 — Crypto self custody wallet *2021-11-30, version 4.7.0* Klever is a super easy, user friendly self custody crypto wallet. Great to see support for more chains added. Special attraction is a built in dex called klever swap which I use regularly to swap to other crypto within wallet. Has great future. ### 1/5 — Terrible customer service and support *2021-11-28, version 4.7.0* If you don’t have any other place to go than use this app/wallet, I had a terrible experience with them. Lost my coins by their mistake (misleading information) and was told sorry you can’t get your coins back… customer service is a joke! Just stay away, save your money and time ## Frequently asked questions about K4 Wallet ### What is K4 Wallet?
