What is Citowise?
Citowise was a self-custodial mobile cryptocurrency wallet developed to handle major layer-1 networks alongside tens of thousands of ERC-20 tokens. Built for Android and iOS devices, the application combined client-side key storage, offline hardware wallet connectivity, and built-in payment requests.
Company background and team
The project began in 2016. Citowise Developments OÜ, an operating entity based in Tallinn, Estonia, ran the company. Co-founder and CEO Aleksandr Kents, who studied at Tallinn University of Technology (TalTech), initiated the project alongside co-founder and CTO Max Zab. The founders self-financed initial development after encountering personal crypto loss and usability friction across early mobile clients.
Key features and architecture
Citowise used local storage. Private keys remained on the user's mobile device, encrypted locally with password protection. The application supported networks including Bitcoin, Ethereum, Ethereum Classic, and Bitcoin Cash, and claimed compatibility with over 55,000 ERC-20 tokens. For users seeking cold storage security, the mobile app integrated with Ledger Nano S and Trezor hardware wallets. The interface allowed payment requests via customized QR codes or URLs containing specified settlement amounts. Fiat purchases were also added through payment processor Simplex.
Fees and operational history
The core wallet software was free to download and use, with network transaction fees paid directly to miners or validators on the respective blockchains. Following its initial Android release in 2017, the team incorporated stablecoin support in December 2018 and integrated Bitcoin Cash in October 2018. However, after experiencing mobile app store availability issues, operations ceased and the product was declared inactive in January 2021 when its primary web infrastructure went offline.
Risks and product status
Citowise is defunct. The mobile applications receive no maintenance or updates. Users attempting to interact with obsolete wallet software face seed-phrase exposure risks and unpatched vulnerabilities.

Citowise offered self-custodial mobile storage with broad ERC-20 support, but the wallet was shut down and is no longer available.
Citowise was a non-custodial mobile wallet for Android and iOS, built by Citowise Developments OÜ in Tallinn, Estonia. The project began in 2016 and released its first Android product in 2017. Its main strength was local key management: the website said wallet data stayed on the device and could be decrypted with a password when sending transactions or exporting a wallet. That gives users control of private keys rather than placing balances with a hosted exchange.
Asset coverage was broad for an older mobile wallet. Citowise supported Bitcoin, Litecoin, Ethereum, Ethereum Classic, Bitcoin Cash, EOS, VeChain, TRON, Ontology and other named assets, along with ERC-20 tokens. The site claimed support for 55,000+ tokens. It also offered payment requests through a QR code or URL, an integrated exchange, a currency calculator and hardware-wallet integration with Ledger Nano S and Trezor.
Those features came with limits. Citowise was a mobile wallet only. The website described PIN protection and encrypted private channels. Self-custody also left seed-phrase and device-security risks with the holder, while the integrated exchange could add costs to the underlying conversion.
The company had a named operating entity and identified Aleksandr Kents as CEO and co-founder. Its public history includes the wallet launch and later payment and exchange features, but the service did not maintain a current product presence. The wallet was flagged as inactive after the website became inaccessible on January 19, 2021, and is now discontinued. That is the decisive weakness: existing users cannot treat the old download or feature claims as evidence of a working service.
Citowise suited its original target of mobile users who wanted local key control, ERC-20 support, payment requests and Ledger or Trezor connections in one app.
