Advanced BTC Wallet Capabilities
A modern BTC wallet must support the latest Bitcoin Improvement Proposals (BIPs) to ensure users benefit from network upgrades. Our infrastructure is continuously updated to provide the most efficient, secure, and feature-rich Bitcoin experience available on mobile devices.
Native SegWit Support
Segregated Witness (SegWit) is a protocol upgrade that separates transaction signatures from the transaction data, effectively increasing the block size limit. Our BTC wallet utilizes Native SegWit (bech32) addresses by default, which significantly reduces the data footprint of your transactions.
By using Native SegWit, you benefit from transaction fees that are up to 40% lower than legacy addresses. This ensures that when you move your Bitcoin, you keep more of your wealth rather than spending it on miner fees, especially during periods of high network congestion.
Custom Fee Control
Custom fee control is the ability to manually determine the exact miner fee you are willing to pay to have your transaction included in the next block. Our BTC wallet provides real-time mempool data to estimate exactly how many satoshis per virtual byte (sats/vB) are required to confirm your transaction within your desired timeframe.
Whether you need an urgent transfer to capitalize on a trading opportunity or are simply consolidating UTXOs over the weekend when fees are low, our custom fee slider puts the economic power entirely in your hands, ensuring you never overpay for block space.
Taproot Integration
Taproot is a massive Bitcoin upgrade that introduces Schnorr signatures to enhance privacy and smart contract flexibility. Our BTC wallet fully supports sending to and receiving from Taproot (P2TR) addresses, ensuring you are prepared for the future of Bitcoin development.
By utilizing Taproot, complex transactions—such as multi-signature setups or opening Lightning channels—appear identical to standard single-signature transactions on the public blockchain, drastically improving your on-chain privacy heuristics and lowering overall transaction costs.
Lightning Network Integration
The Lightning Network is a Layer 2 scaling solution built on top of the Bitcoin blockchain that enables instant, nearly free microtransactions. By routing payments through a network of bidirectional payment channels, it bypasses the 10-minute block confirmation time and high fees of the base layer.
Our BTC wallet features seamless Lightning Network integration, allowing you to instantly pay for goods, services, or send remittances across the globe for fractions of a cent. You no longer need to wait for on-chain confirmations to settle everyday transactions, making Bitcoin a truly viable medium of exchange.
The wallet automatically manages channel liquidity and routing algorithms in the background, providing a frictionless user experience. You simply scan a Lightning invoice, confirm the amount, and the payment settles instantly with cryptographically guaranteed finality.

Hardware Wallet Support
Hardware wallet support allows users to combine the intuitive interface of a mobile application with the impenetrable security of an offline, dedicated signing device. This hybrid approach represents the gold standard for securing large amounts of Bitcoin.
Connect Ledger Devices
Seamlessly pair your Ledger Nano X or Nano S Plus directly with our BTC wallet via Bluetooth or USB-C. This integration allows you to use the Kraken app as a beautifully designed companion interface to view your balances, generate receiving addresses, and construct transactions without exposing keys.
When it is time to send funds, the transaction is pushed to your Ledger device for physical confirmation. Your private keys never leave the secure element of the hardware wallet, ensuring that even if your mobile phone is completely compromised by malware, your Bitcoin remains absolutely safe.
Trezor Integration
For users who prefer open-source hardware solutions, our BTC wallet offers robust integration with Trezor Model T and Trezor Safe devices. Connect via USB to instantly synchronize your extended public keys (xPubs) and monitor your cold storage portfolio on the go.
Our application supports advanced Trezor features including hidden wallets protected by passphrases, allowing for plausible deniability and ultimate protection against physical duress attacks. Manage your deepest cold storage with the convenience of a modern mobile interface.
Uncompromising Privacy Features
On-chain privacy is the ability to transact on a public ledger without revealing your total net worth, spending habits, or counterparty relationships to blockchain surveillance firms. Our BTC wallet implements industry-leading privacy best practices by default.
Advanced Coin Control
Coin control is a feature that allows users to manually select which specific Unspent Transaction Outputs (UTXOs) are consumed when creating a new Bitcoin transaction. Instead of letting the wallet algorithm randomly mix your funds, you have granular control over your digital footprint.
By using coin control in our BTC wallet, you can prevent "dust" attacks, isolate KYC-tainted coins from non-KYC coins, and ensure that a payment to a merchant doesn't accidentally reveal the existence of a massive cold storage UTXO. This level of control is essential for true financial sovereignty and privacy.
Address Reuse Prevention
Address reuse prevention is the cryptographic practice of generating a brand new, unique receiving address for every single transaction. This prevents outside observers from easily linking multiple payments to a single identity or calculating your total wallet balance.
Our BTC wallet utilizes Hierarchical Deterministic (HD) architecture (BIP32/BIP44) to automatically generate a fresh receiving address every time you request a payment. The wallet seamlessly tracks all these addresses in the background, consolidating your total balance in the UI while keeping your on-chain activity highly obfuscated and secure.
Buy Bitcoin Directly
Skip the complex exchange withdrawal process. You can purchase Bitcoin directly within the BTC wallet using your credit card, debit card, or Apple/Google Pay. The purchased satoshis are deposited directly into your self-custodial addresses.
Frictionless On-Ramping
Frictionless on-ramping is the process of converting traditional fiat currency into cryptocurrency without leaving the secure environment of your self-custodial application. This eliminates the need to trust centralized exchanges with custody during the purchasing phase.
Our integrated purchasing widget partners with industry-leading fiat gateways to provide highly competitive exchange rates and instant settlement. Once the purchase is approved by your bank, the Bitcoin is broadcast directly to an address mathematically derived from your private keys.
This means from the very first moment you own the Bitcoin, you are the sole custodian within your BTC wallet. There are no withdrawal holds, no exchange insolvency risks, and no complex transfer procedures. It is the fastest, safest way to stack sats directly into cold storage.
How to Safely Backup Your BTC Wallet
A wallet backup is the physical documentation of your 12-word or 24-word cryptographic seed phrase, which serves as the ultimate master key to your Bitcoin. If your device is destroyed, this backup is the only way to recover your wealth.
Step 1: Prepare an Offline Environment
Before generating or viewing your recovery phrase, ensure you are in a completely private environment. Close all screen recording applications, turn off smart cameras or webcams in the room, and ensure nobody is standing behind you. The security of your BTC wallet depends entirely on this phrase remaining unseen by digital eyes.
Step 2: Write on Physical Media
Using a pen, write down the 12 words exactly as they appear on your screen, in the exact numbered order. Do not take a screenshot. Do not type them into a notes app or password manager. Digital storage is vulnerable to hackers; physical paper or specialized steel backup plates are immune to remote digital theft.
Step 3: Verify the Sequence
The BTC wallet application will prompt you to verify the backup by asking you to re-enter specific words from the phrase you just wrote down. Double-check your spelling against the official BIP39 word list. A single misspelled word or incorrect order will render the entire backup useless during a recovery attempt.
Step 4: Secure Storage and Redundancy
Place your written backup in a highly secure physical location, such as a fireproof safe or a bank safety deposit box. For significant amounts of Bitcoin, consider creating multiple physical copies stored in geographically separate locations to protect against localized disasters like fires or floods. Never store the phrase alongside the device it protects.
