UCDx will maintain and enforce open standards to ensure interoperability and account portability between different wallet providers.

Whether any software components are made available open-source is a secondary issue, to which the answer is not yet clear.  However, the Open Wallet Foundation was set up in 2002, as an offshoot of the Linux Foundation, to encourage the development of open-source software for wallets, and UCDx is all in favour: there is no point in developing multiple, competing, commercial versions of what should be interoperable code.

Many web browsers are now built on a common open-source core. Only the cosmetics differ. UCDx hopes that wallet software will follow the same pattern.
