Bank of America's Hundreds of Blockchain Patents Point to Future Digital Finance Ambitions
Bank of America (BofA) has emerged as a leader in blockchain patent development, with a portfolio spanning identity verification, smart contract governance, and tokenized asset controls. As of 2019, the bank held 82 blockchain patents, the most of any financial firm at the time, according to EnvisionIP data cited by CNBC. CEO Brian Moynihan confirmed the bank holds hundreds of blockchain patents, though regulatory restrictions have limited its ability to launch direct crypto products.
The bank's patent filings cover four key areas: distributed identity verification, smart contract modification, tokenized asset controls with geofencing, and AI-driven interbank settlement systems. For example, one patent application from June 2026 describes a system for masking customer information using hash functions, while another from May 2026 proposes a framework for altering smart contract endorsements. These filings suggest the bank is focusing on institutional settlement and compliance tooling rather than retail cryptocurrency trading.
Despite its extensive patent portfolio, BofA does not currently offer direct cryptocurrency trading or custody. However, Merrill and Private Bank advisers have been able to recommend spot bitcoin ETFs to eligible wealth clients since January 2026. The gap between the bank's patent development and limited crypto services highlights its cautious approach to blockchain technology.
BofA is also exploring stablecoin issuance alongside other major banks, including JPMorgan Chase and Citigroup. The bank's patent portfolio could support infrastructure for regulated digital-dollar payment systems, though the timing of any commercial deployment depends on final rulemaking under the GENIUS Act and potential new market structure legislation.
