What is Blox?
Blox was a cryptocurrency asset tracking, accounting, and tax bookkeeping platform built for digital asset businesses and finance teams. The service synced transaction data from exchanges and blockchains and supported over $2B in assets under management across its corporate client base.
Founders and corporate background
Alon Muroch and Adam Efrima founded Blox in 2017. Muroch, serving as chief executive officer, previously contributed code to Bitcoin and Ethereum and created an early peer-to-peer multisignature wallet in 2014. Co-founder Efrima previously held the role of operations director at a Shanghai-based financial technology firm. Headquartered in Tel Aviv, the business operated offices across San Francisco, Shanghai, and Gibraltar, employing 29 people by December 2020. Corporate clients and platform users included blockchain entities such as eToro, 0x, Zilliqa, and Decentraland.
Financial tracking and cost-basis tools
The platform connected to public blockchain addresses and exchange accounts for asset tracking. Blox Business tracked balances across corporate accounts and blockchain addresses. In November 2019, the company launched an automated cost-basis tool that pulled historical trading records in real time. This mechanism calculated cryptocurrency profit and loss from historical records.
Acquisition and current availability
Blox grew its customer base to around 100 enterprise clients, reporting $240K in annual revenue in 2019. In October 2021, institutional crypto software provider Lukka acquired Blox. Following the transaction, the standalone blox.io software suite and web domain were phased out and are no longer active for independent registration or self-service tax preparation.

Blox provided institutional crypto bookkeeping and real-time cost-basis tracking for corporate teams, but the platform was acquired by Lukka in 2021 and its standalone service is inactive.
Blox was founded in 2017 in Tel Aviv by Alon Muroch and Adam Efrima to provide crypto asset tracking, bookkeeping, and tax calculation tools for enterprise organizations. Rather than targeting casual retail filers, the software served corporate crypto treasuries and funds, counting organizations such as eToro, Zilliqa, 0x, and Decentraland among its users. In November 2019, the team introduced an automated cost-basis calculation tool built to pull historical ledger records across multiple accounts to calculate real-time capital gains and losses.
The platform offered notable operational strengths for finance teams managing corporate digital asset balances:
- Automated historical record sync that retrieved cost basis and balance figures directly across integrated exchange accounts and blockchain addresses.
- Enterprise-level bookkeeping features designed to handle large balance sheets, with support for more than $2B in crypto assets under management across its corporate client base.
- Institutional portfolio tracking tailored for corporate finance teams.
Trade-offs and limitations defined the product before its acquisition. Blox focused on enterprise crypto accounting workflows rather than retail tax filing. The company reported 100 customers and $240K in annual revenue in 2019. In October 2021, crypto accounting firm Lukka acquired Blox. The standalone blox.io application has ceased operations.
