Descriptiontext

Bitkey is a bitcoin self-custody wallet product developed by Block, Inc. (NYSE: SQ), designed to make secure bitcoin storage accessible to mainstream consumers without requiring technical expertise. The product addresses the core trade-off in bitcoin custody: traditional hardware wallets depend on single seed phrases that can be lost, stolen, or forgotten, while custodial solutions require users to trust a third party. Bitkey employs a 2-of-3 multisig architecture that distributes keys across a mobile app, a hardware device, and Bitkey's server (hosted in AWS Nitro Enclave), ensuring no single device, key, or party can move funds unilaterally. The product began commercial shipping in March 2024 and is available in 95+ countries.

The platform comprises three integrated components: a $250 hardware device with fingerprint authentication and NFC connectivity, a mobile application (iOS/Android) for transaction management, and a set of recovery tools including social Recovery Contacts, an Emergency Exit Kit (encrypted PDF containing the app key), and an Inheritance Feature with a six-month beneficiary waiting period. A notable technical contribution is the Chain Code Delegation Bitcoin Improvement Proposal (BIP), authored by Bitkey engineers, which modifies how collaborative multisig wallets share transaction data to prevent third-party cosigners from viewing user balances and history. The product is bitcoin-only by design to minimize attack surface and complexity.

Bitkey's go-to-market combines direct e-commerce (bitkey.world) with retail distribution through Amazon and Best Buy, plus a US pickup point network spanning nearly 9,000 Walgreens locations, FedEx, Dollar General, Albertsons, and Kroger. Revenue is generated primarily through one-time hardware sales at $250 per unit with no subscription fees for core functionality. Indirect revenue contribution flows through Block's broader ecosystem, including Cash App integration and Square's merchant bitcoin payments infrastructure (over 800,000 merchants enabled as of April 2026). Strategic integration partnerships with Coinbase, Cash App, Robinhood, MoonPay, Strike, Blockchain.com, and Azteco enable users to purchase and transfer bitcoin directly into Bitkey wallets.

CoinMarketCapBlock Launches Its First-Ever Bitcoin Consumer Ad Campaign: Guest Post by BlockchainReporterBlock launched its first Bitcoin consumer ad campaign, 'Bitcoin Does,' on October 1, targeting about 60 million bitcoin-curious Americans. The campaign recasts Bitcoin as practical money, using Cash App, Square, and Bitkey, and will run across streaming, TV, and theaters through December 31.Crypto BriefingBitkey demos Emergency Exit Kit for fund recovery without app accessBitkey, the Bitcoin hardware wallet built by Block, Inc., introduced the Emergency Exit Kit, a self-rescue feature letting users transfer funds without accessing Block's servers or app. It uses a 2-of-3 multisig setup where the user holds an App Key and Hardware Key, while Block holds the third. The kit requires sideloading an open-source Android utility tool and costs $150.Crypto BriefingCash App launches fee-free Bitcoin DCA and Bitkey wallet integrationBlock's Cash App has launched Auto Invest, a feature enabling fee-free recurring Bitcoin purchases starting at $1 with automatic routing to Bitkey hardware wallets for self-custody. The platform eliminates both fees and spreads on purchases while offering 5% Bitcoin Back rewards, maintaining a 1:1 Bitcoin reserve ratio and supporting Lightning Network transfers. The integration creates a compounding accumulation system requiring minimal user management, representing a significant expansion of Block's integrated Bitcoin stack.Crypto BriefingBitkey fast-tracks coin control feature after customer demandBitkey, the Bitcoin-only hardware wallet built by Block, Inc., is accelerating development of a coin control feature that lets users label individual UTXOs and manually select which coins to include in transactions, responding directly to persistent customer demand. The feature addresses privacy concerns by preventing automatic merging of coins from different sources and allows users to optimize transaction size to avoid overpaying network fees. The addition aligns Bitkey with privacy-focused wallets like Sparrow, Electrum, and Trezor Suite, which have offered similar coin control capabilities for years.Crypto BriefingBitkey addresses vulnerability flagged by researcher, confirms no risk to fundsBitkey, the self-custodial Bitcoin wallet built by Block (formerly Square), patched a security vulnerability in its recovery and inheritance contact setup flows on August 1, after security researcher @1440000bytes flagged the issue the same day. The company confirmed no user funds were at risk due to its defense-in-depth architecture, which would have prevented unauthorized access even if the narrow exploitation window had been targeted. Bitkey held a public technical discussion on August 2 to explain the vulnerability, the fix, and the security measures that protected users.BlockBitcoin Day is live: Cash App, Square, and Bitkey are giving away $1 million in bitcoinBitcoin Day is being celebrated from April 6 to April 10 with a $1 million bitcoin giveaway by Cash App, Square, and Bitkey to promote the use of bitcoin in everyday transactions.BlockChain Code Delegation: Improving privacy in collaborative multisigBitkey engineering team members Jonathan Pollock and Jurvis Tan authored a Bitcoin Improvement Proposal (BIP) called Chain Code Delegation that modifies how multisig arrangements share information to prevent third-party cosigners from viewing a user's full wallet balance and transaction history. The proposal has been submitted for review and discussion as an open, community-vetted standard that any wallet or custody provider can adopt. Bitkey plans to be the first to implement Chain Code Delegation in production, enabling private collaborative wallets for Bitcoin users.BenzingaJack Dorsey Advocates for Bitcoin Use as Everyday Currency ‘As It Was Designed to Be'Block CEO Jack Dorsey has reiterated his position that Bitcoin should be used for daily transactions rather than speculation, describing it as 'p2p electronic cash' as originally designed by Satoshi Nakamoto. Dorsey highlighted Block's comprehensive Bitcoin ecosystem including Square for merchant payments, Cash App for consumer transactions, Bitkey hardware wallet, and Proto mining infrastructure. Treasury Secretary Scott Bessent also signaled the U.S. government's interest in accumulating more Bitcoin, indicating a potential shift in governmental attitudes toward cryptocurrencies.BitcoinmagazineA Seed Phrase Isn’t Self Custody, It’s A Liability.A guest opinion argues that seed phrases, currently the industry standard for Bitcoin self-custody, function as liabilities due to security risks and poor user experience rather than true capability. The article suggests that relying on these static recovery methods hinders widespread adoption and calls for more intuitive, software-based security solutions. This perspective is presented by a member of the Bitkey team at Block.BitkeyBitkey Bitcoin WalletBitkey, a Bitcoin wallet provider established by the team behind Square and Cash App, is marketing its hardware wallet which features a 2-of-3 multisig security setup and built-in inheritance capabilities. The product is priced at $99 (discounted from $150) and emphasizes self-custody with enhanced privacy protections for users.
