Walletium Review 2026: A Telegram Crypto and Fiat Wallet

Walletium is a Telegram-based wallet for managing cryptocurrency and traditional currencies. Its stated features include sending, receiving, and swapping assets, viewing transaction history, and using virtual cards. The project describes its service as a hybrid of custodial and non-custodial wallet functions.

The Telegram format may appeal to people who want to handle payments from a chat-based interface. Walletium also describes integrations with Telegram bots for automated payments. It names Bitcoin, Ethereum, and stablecoins as examples, but does not provide a complete asset or network list in its overview.

Walletium’s documentation lists encryption and two-factor authentication, but does not identify an independent security audit. Fees, detailed key-management arrangements, card terms, and the jurisdictions where the service is available are not specified in the overview.

Walletium presents itself as a Telegram mini app that combines crypto and fiat management. Users can view balances and transaction history, send or receive payments, and convert between supported cryptocurrencies and traditional currencies. It also describes integrations with Telegram bots for automated payments.

Walletium says its service uses both custodial and non-custodial arrangements. In a custodial setup, a provider holds or manages assets on a user’s behalf; in a non-custodial setup, the user controls the wallet keys. Walletium’s overview does not explain how it assigns these arrangements to particular assets or features, so users should check the specific custody and recovery terms before depositing.

Walletium does not publish transfer, swap, currency-conversion, or virtual-card fees in its overview. Check the applicable costs and exchange rate in the app before confirming a transaction; card terms may also affect the total cost.

Walletium says it uses encryption and supports two-factor authentication, but these are project claims rather than an independent security assessment. An audit is not identified. Its hybrid custody model makes it especially important to understand who controls the keys, how backups work, and what happens if access to the Telegram account or service is lost; the overview does not explain these details.

Walletium describes its service as having custom regulation, but does not identify a regulator or jurisdiction in the overview. Supported countries and card eligibility are also unspecified. Review the current terms and custody details before depositing or relying on a virtual card.

Walletium is aimed at people who already use Telegram and want to manage crypto and fiat payments from a chat-based app. It may be worth considering if you value transfers and swaps in one interface, but users who need clear information about key custody, supported networks, card costs, or regulatory coverage should verify those details before relying on the service.
