P.CASH: A Review of a Privacy-Focused Wallet with Tangem Integration

Most modern cryptocurrency wallets are designed with a mobile-first approach, prioritizing non-custodial storage and open-source code. One such solution is the P.CASH wallet. In this article, we explore a multi-currency app that supports PirateCash and Cosanta cryptocurrencies, along with over 20 other blockchains, and features unique integration with the Tangem hardware wallet.

Origin and Technical Features

P.CASH is a non-custodial cryptocurrency wallet with open-source code, developed for Android devices. The project began as a fork of Unstoppable Wallet, leveraging its proven architecture while adding new capabilities. “Over two years of independent development, we’ve introduced unique features, including native support for PirateCash and Cosanta, integration with Tangem, built-in staking, and a premium access model based on token holding,” the developers state.

The app is written in Kotlin and is compatible with Android 8.1 and above. Its source code is fully available on GitHub, emphasizing the project’s transparency.

Privacy Philosophy and Distribution

P.CASH is distributed through F-Droid, a platform focused on free and open-source software, popular among privacy advocates. F-Droid avoids ads, trackers, and account registration requirements. “By choosing F-Droid as a primary distribution channel alongside Google Play, we demonstrate our commitment to privacy and the absence of hidden data collection,” the developers highlight.

Supported Blockchains and Assets

P.CASH supports over 20 blockchains, including:

• Bitcoin, Ethereum, and L2 solutions (Arbitrum, Optimism, Base, zkSync);
• TRON, BNB Chain, Avalanche (C-Chain), Solana (with SPL tokens), TON (with TON Connect);
• Classic coins: Litecoin, Dash, Bitcoin Cash, Dogecoin, Stellar, Fantom, Gnosis, eCash.

Special attention is given to privacy-focused cryptocurrencies. P.CASH supports Zcash with both transparent and shielded addresses, as well as Monero, enabling wallet imports via a 25-word seed phrase. “We’ve added support for Monero with non-standard 12 or 24-word seed phrases,” the developers note.

Central to the ecosystem are PirateCash and Cosanta, blockchains developed by the P.CASH team. PirateCash targets gaming ecosystems, while Cosanta focuses on enterprise solutions. The wallet serves as the official interface for both networks, supporting their native and wrapped tokens on BNB Chain.

Seed Phrase Flexibility

P.CASH supports the BIP-39 standard, allowing users to create or import seed phrases of 12, 15, 18, 21, or 24 words. This ensures compatibility with wallets from other applications. For Monero, the wallet supports 25-word seed phrases, with the final word acting as a checksum.

Built-In Exchange Features

P.CASH offers integrated asset exchange tools through:

• PancakeSwap DEX (BNB Chain);
• 1inch aggregator;
• THORchain cross-chain protocol;
• ChangeNOW exchange;
• Near-intents.org, Ston.fi, and MayaSwap platforms.

“We closely collaborate with ChangeNOW, enabling users to swap Zcash, Dash, and other coins directly in the app without withdrawing to an exchange,” the developers explain. Support for WalletConnect and TON Connect provides access to DeFi ecosystems on Ethereum, Solana, and TON.

Tangem Integration

In 2025, P.CASH introduced support for the Tangem hardware wallet, a card with an NFC chip that securely stores private keys. Users can create a new wallet or connect an existing one. The team plans to release branded P.CASH cards. The setup process mirrors that of the Tangem app, simplifying adoption.

Premium Features

P.CASH offers premium access activated by holding a certain amount of PIRATE or COSA tokens. Unlike traditional subscriptions, this model allows users to retain ownership of their tokens, which can be sold if desired. Premium features include:

• Address verification to detect links to fraudulent schemes;
• Hidden wallet;
• PIN code for wallet deletion;
• Analysis of incoming transactions for phishing or sanction risks.

New users receive a 30-day free trial of premium features. Basic functionalities (storage, transfers, DEX) are available for free.

Drawbacks and Risks

The primary drawback is the lack of an independent security audit. While the Unstoppable Wallet codebase is reliable, new features and integrations with PirateCash and Cosanta introduce potential vulnerabilities. The project’s heavy reliance on PIRATE and COSA tokens, with low market capitalizations ($2 million and $878,000 per CoinGecko data as of September 2025), makes using the wallet a bet on these assets’ success.

The limited user base (87 reviews with a 5.0 rating on Google Play) suggests a niche audience tied to the PirateCash and Cosanta communities. Some antivirus software may falsely flag the app as a miner due to the Monero library, but this is a false positive, confirmed by VirusTotal analysis.

Competition and Target Audience

P.CASH competes with Unstoppable Wallet, which has a longer history and recognition on Bitcoin.org and Ethereum.org. However, for users within the PirateCash and Cosanta ecosystems, P.CASH is the preferred choice due to its native support and unique features.

Conclusion

P.CASH is a multi-currency wallet focused on privacy, open-source code, and Android support. Its integration with Tangem, built-in exchanges, and token-based premium features make it stand out. The team has been actively developing the project since 2018 and plans to attend Blockchain Life 2025 in Dubai, offering a 10% discount with the promo code P.CASH.

Despite the lack of an iOS version and security audit, P.CASH appeals to privacy advocates and enthusiasts of PirateCash and Cosanta. It’s a niche but promising solution for those who value openness and functionality.
