United States-based investment banking company Bank of America (BofA) has filed a patent for a digital currency wallet with multiple layers of asset access. The proposed wallet would accept different passwords for different amounts of funds requested. 

The United States Patent and Trademark Office published BofA’s application on Aug. 15. Per the filing, this technology would comprise a computing platform with a digital wallet interface. 

The platform would be configured to operate within a peer-to-peer network for blockchain management — which could potentially be public or private.

The application points to Bitcoin (BTC) and Ether (ETH) as examples of digital currencies that are increasingly gaining attention, and — per the filing — driving the need for better wallet infrastructure. As an example of how the wallet could work with top cryptos, BofA says:

“As an illustrative example, the user may have logically abstracted 4 BTC and 20 ETH in the first tier of the digital wallet interface. The user may specify a first network function request for the Bitcoin decentralized P2P network involving 3 BTC and an address within the Bitcoin network, and a second network function request for the Ethereum decentralized P2P network involving 10 ETH and an address within the Ethereum network.”

According to the filing, there are currently a number of issues with cryptocurrency wallet security, particularly in regard to private key management. Namely, private keys held by users are susceptible to theft or mishandling, and private keys held by third parties are no longer wholly-owned by users. BofA believes that their multi-tiered wallet system would be more secure than current wallet systems.
