Casa vs Strike

Casa operates as a specialized multi-signature collaborative custody provider rather than a pooled custodial service or broad exchange. The architecture is engineered around threshold cryptography models, most notably two-of-three and three-of-five vault configurations for Bitcoin, alongside smart contract-based multi-key protection for Ethereum and select ERC-20 assets such as USDT and USDC. Instead of generating a single master recovery phrase that exposes an entire treasury if compromised, Casa segments transaction authorization across discrete keys stored on separate hardware units, the user mobile phone, and Casa encrypted signing servers.

This selective design deliberately avoids broad token catalogs. Casa prioritizes security auditing and protocol stability over wide asset coverage, making it unsuitable for individuals seeking exposure to decentralized finance tokens or high-frequency staking ecosystems. For supported assets, vault accounts operate with native blockchain addresses, providing full transparency through public explorers while keeping signing credentials isolated across distinct secure enclaves and hardware models like Trezor, Ledger, Coldcard, and Passport.

Strike takes an intentional, single asset orientation compared to generalized digital currency platforms. The core ecosystem focuses entirely on Bitcoin, utilizing both standard onchain settlement layers and the Layer 2 Lightning Network for rapid balance routing. In select international corridors, Strike also facilitates the holding and transfer of Tether USDt to streamline cross border payments where access to domestic banking rails remains constrained.

Users can utilize Strike for multiple distinct functional workflows. For individual consumers, the app functions as a digital wallet balance denominated in either local fiat currency or bitcoin. The platform features automated direct deposit configuration, enabling individuals to convert a percentage of their incoming paycheck directly into bitcoin upon arrival. In addition, its Send Globally mechanism converts domestic currency balances into bitcoin, routes value across the Lightning Network instantly, and converts funds into local fiat currency accounts or mobile money destinations in Latin America, Africa, and Southeast Asia. On the commercial side, Strike offers merchant checkout solutions, invoice generation tools, and developer APIs designed to accept bitcoin and Lightning payments while optionally auto settling the revenue in fiat currency to reduce balance sheet exposure.

Unlike traditional non-custodial crypto software that is distributed as free open-source utilities, Casa operates on a tiered annual software-as-a-service subscription model. Standard tiers range from entry-level single-key mobile management up to structured two-of-three multi-key vaults, with higher enterprise and private client tiers unlocking three-of-five security setups, dedicated account management, custom video verification, and legal inheritance documentation support. Pricing reflects the maintenance of collaborative signing infrastructure, mobile app synchronization, and concierge support rather than per-transaction percentage cuts.

When broadcasting transactions, users do not pay percentage spreads or custody management fees to Casa. Outgoing transfers incur standard network mining or gas fees paid directly to blockchain validators. Casa does not impose additional withdrawal surcharges, though users should account for the ongoing recurring software subscription cost when evaluating their overall holding overhead. For smaller balances, these annual subscription tiers may represent a noticeable fraction of total wealth, whereas for sizable balances, the fixed fee model compares favorably to asset-weighted management percentages.

The cost architecture on Strike is designed around transparent fee tiers and low transaction friction. Standard spot bitcoin purchases carry a transparent spread built into the market quote alongside a low platform fee. Strike incentivizes long term accumulation through its recurring purchase program, waiving base execution fees for automated hourly, daily, weekly, or monthly buys after the target schedule has run continuously for seven days.

For funding and disbursements, Automated Clearing House transfers and select domestic bank rails are supported with zero deposit surcharges from the platform, although bank wire fees or debit card processing percentages apply based on the user payment method selected. When moving bitcoin off the platform, Strike provides tiered withdrawal mechanics. Users executing onchain bitcoin withdrawals can select standard settlement, which batches transactions over a multi hour window to provide free network routing. Expedited onchain transactions incur standard network mining fees. Transactions sent across the Lightning Network remain free of platform surcharges, making micropayments and cross border transfers cost efficient relative to traditional international wire intermediaries.

The core defensive premise of Casa is the total elimination of unilateral custody risk. In a standard two-of-three vault setup, the user controls two keys (typically one mobile key and one dedicated hardware wallet), while Casa maintains the third key on a secure server. To spend funds, any two signatures are required. Under standard operating conditions, the user signs with their mobile device and hardware wallet, completing transfers without needing Casa signature intervention. Casa cannot initiate transfers, seize assets, or block on-chain transactions unilaterally because it possesses only one signature.

If a hardware device is lost or damaged, Casa signing service assists the user by cosigning a recovery transaction alongside the remaining user mobile key, allowing the vault balance to sweep to a freshly configured multi-key arrangement. For scenarios where Casa infrastructure is temporarily or permanently unavailable, the platform provides open-source sovereign recovery tools and encrypted key backups, enabling users who retain their two personal keys to reconstruct their transactions independently via standard external tools.

Strike utilizes a centralized custodial architecture for balances maintained inside the application. Digital assets and cash equivalents are helps protect through a combination of institutional custody partners and regulated cold storage environments. Because Strike retains custody of the underlying private cryptographic keys, users do not directly manage seed phrases within the core app interface. Instead, the service positions itself as an operational spending and purchasing account, encouraging users with significant balances to withdraw funds to hardware devices or self custody software.

Account protection relies on standard commercial security standards. User profiles require multi factor authentication, utilizing time based one time password applications or hardware security keys to prevent unauthorized account access via mobile credential interception. The application also provides granular address whitelisting options for external withdrawals, allowing individuals to lock destination wallets to pre approved cryptographic addresses. Strike operates within United States state level money transmitter licensing frameworks and complies with standard Bank Secrecy Act and Anti Money Laundering reporting rules, maintaining strict account identity verification procedures for customer accounts.

Headquartered in the United States, Casa offers its software services globally, subject to standard international sanctions and export compliance regulations. Because Casa does not accept fiat deposits, act as a custodial broker, or operate an order-matching exchange, onboarding avoids intrusive banking identity hurdles for entry tiers, though premium tiers with inheritance onboarding may involve formal identity checks and video verification to establish protocol recovery rules. The mobile application is available internationally on iOS and Android app marketplaces.

Customer support quality varies significantly by subscription level. Standard users receive access to comprehensive technical documentation, educational self-guided setup wizards, and responsive ticket-based customer support. Higher private client tiers receive personalized onboarding sessions, direct advisor channels, and annual security health audits. The platform also offers an integrated health check system within the app, prompting users to periodically verify that their disparate hardware devices remain operational and properly synchronized without exposing private seed information.

Strike maintains broad availability across the United States, operating as a licensed money transmitter in individual states and territories. However, specific state level permissions can create minor differences in available payment methods, deposit limits, or feature rollouts. Internationally, the platform has expanded availability to dozens of countries across Europe, Latin America, Africa, and Asia, though certain markets interact with Strike purely through stablecoin settlement rails or remittance recipient interfaces rather than full fledged local fiat onramps.

Customer support is primarily delivered asynchronously through an in app ticketing system, searchable knowledge base, and email support team. Response times are generally aligned with typical financial technology platforms, though complex balance reconciliations or extended account compliance reviews can require additional turnaround time. The platform provides detailed account transaction exports and tax documentation summaries to assist users in tracking cost basis figures for capital gains reporting across accounting periods.
