Infinitism

Account-Abstraction (EIP-4337) singleton EntryPoint implementation. Only one instance required on each chain.

Provides the basic logic for implementing the IAccount interface - validateUserOp. A specific account implementation should inherit it and provide the account-specific logic.

Helper contract for EntryPoint, to call userOp.initCode from a "neutral" address, which is explicitly not the entryPoint itself.

Various helper functions for EIP-4337 contracts

Manage deposits and stakes for UserOperations (either by a paymaster or an account). Stake is value locked for at least "unstakeDelay" by a paymaster.

ERC4337 helper class for creating a paymaster that provides a helper methods for staking. Validates that the postOp is called only by the entryPoint.
