Account Abstraction - Schnorr Multi Signature ERC-4337 compliant smart contracts.

Package contains two main contracts:

• MultiSigSmartAccount - ERC-4337 Account Abstraction implementation
• MultiSigSmartAccountFactory - factory contract for account abstraction

Account Abstraction is UUPS Upgradeable Proxy and implementation can be upgraded only by the Owner. The Owner Role is granted for every Schnorr's combined public address - combinedAddress - passed during Account initialization (read more about the combinedAddress creation here ). It means that the most crucial functions, such as upgrade or deposit withdrawal, can be done only if a transaction is signed with Schnorr Multi-signature algorithm.

• Node: >=18.0.0 <20.0.0
• npm (Node.js package manager): v9.x.x
