How does this relate to account abstraction and 4337?

Account abstraction and 4337 are often associated with Smart Contract Accounts and refer to both the set of UX improvements offered by an SCA (account abstraction) and a specific standard for implementation of these UX improvements (EIP-4337).

The OneBalance account model provides the same UX improvements as SCAs and is backward compatible with using 4337 for the settlement of locks on the chain as user ops.

However, since OneBalance is a general framework for the creation of credible accounts, it is not limited to chains where account abstraction and 4337 are actively being used.

OneBalance is supportive of chains and proxy accounts which opt for using dos resistant user ops like 4337.
