1. Unwavering Focus: Why Bitcoin-Only Matters
BlueWallet’s core appeal to Bitcoin maximalists lies in its **monolithic focus**. It is a Bitcoin-only application, avoiding support for altcoins, NFTs, or multi-chain functionality. This design choice is not a limitation; it is a feature. By supporting only BTC, the wallet significantly reduces its **attack surface** and avoids the technical complexity and regulatory uncertainty that comes with managing thousands of non-Bitcoin assets. This singular dedication aligns perfectly with the maximalist view that Bitcoin is the only decentralized asset worth supporting and securing.
2. Advanced Sovereignty: PSBT, Cold Storage, and Coin Control
★ PSBT Integration for Air-Gapped Security
For serious long-term security (cold storage), BlueWallet implements **Partially Signed Bitcoin Transactions (PSBT)**. This feature allows users to construct a transaction on their internet-connected phone (the 'Watch-Only' wallet) and securely transfer the unsigned data via QR codes or file to an air-gapped hardware wallet (like Coldcard) for signing. The private keys never touch an internet-connected device, providing the highest level of security demanded by maximalists.
★ Coin Control and Privacy
BlueWallet offers **Coin Control**, an essential privacy feature. It allows users to manually select which specific unspent transaction outputs (UTXOs)—the specific 'coins' received from previous transactions—to spend. This prevents common chain analysis heuristics that try to link different transactions to the same identity, giving users granular control over their on-chain privacy.
★ Native Lightning Network Support
Recognizing the need for Bitcoin to function as a medium of exchange, BlueWallet provides seamless integration with the **Lightning Network**. This Layer 2 solution enables instant, high-volume micro-transactions at virtually zero cost, solving Bitcoin’s scalability challenge without compromising its decentralized principles. The option to connect to a user’s **own Bitcoin node** via Electrum Personal Server further reinforces the principle of "Don't trust, verify."
3. Functional Clarity: Wallet vs. Financial Units
BlueWallet maintains clear boundaries, serving solely as a self-custody tool, not a financial services platform. This commitment to being a secure holding and transaction layer, rather than a centralized exchange or bank, enhances its standing among those prioritizing trust minimization.
- Spot Trading Unit: BlueWallet **does not** contain a built-in spot trading engine, swap feature, or fiat on/off-ramp (aside from simple redirects to third-party services). Users maintain sovereignty by requiring external, user-chosen exchanges for trading activities.
- Perpetuals (Perps) & Lending Unit: Crucially, BlueWallet **does not** facilitate any form of leveraged futures trading or decentralized/centralized lending protocols. The BTC held remains secure, non-encumbered capital, fully under the user's control, avoiding the custodial risks and complexities associated with financial derivatives.

5. FAQs: Security and Sovereignty
Q: What is a Watch-Only wallet, and how does it enhance security?
A: A Watch-Only wallet is created by importing a hardware wallet's **public key** into BlueWallet. It allows you to monitor balances and generate receiving addresses on your phone (hot), but requires the private key (cold) on the hardware device to sign and spend funds. This is a critical cold storage workflow.
Q: What is the "Plausible Deniability" feature?
A: This feature allows you to set up a secondary password that decrypts a completely separate, decoy wallet, rather than your main funds. This is an advanced security measure designed to protect users in case of forced disclosure of access.
Q: Does BlueWallet support Ethereum or other smart contract chains?
A: No. BlueWallet is **strictly Bitcoin-only**. This is intentional, as it removes the complexities, potential vulnerabilities, and philosophical opposition to supporting other chains, reinforcing its maximalist appeal.
Q: Why would I use Coin Control?
A: Coin Control is used to maintain better transaction privacy and fund management. For instance, you can avoid mixing funds you received from a KYC'd exchange with funds received anonymously, thus helping to break the links used by chain analysis firms.
Q: Can I use my own Bitcoin Node with BlueWallet?
A: Yes. Advanced users can plug BlueWallet into their own Bitcoin Full Node (via Electrum Personal Server or Electrs). This is the gold standard for sovereignty, ensuring you verify every transaction and wallet balance against your own trusted source.
Conclusion: The Epitome of Digital Gold Custody
BlueWallet is more than just a place to store Bitcoin; it is an active expression of the Bitcoin maximalist philosophy. By providing professional-grade tools like PSBT, Coin Control, and self-node connectivity within a simple, open-source, mobile application, it ensures that users can uphold the highest standards of financial sovereignty and security. It avoids the distractions of the wider crypto ecosystem to focus on making Bitcoin the most secure and usable form of digital money.
