• Added RBAC (Role Based Access Control) contract, which allows you to define specific PERMISSIONS for specific RESOURCES and aggregate them into the roles. The roles can be further assigned to the users.

compound-rate-keeper

• Added AbstractCompoundRateKeeper contract, which implements the logic of calculating compound interest with different capitalization periods.

• Added preset with ownable logic - OwnableCompoundRateKeeper.

contracts-registry

• Added ContractsRegistry module, which can store system contracts, upgrade them, and resolve their dependencies via a special mechanism. The module can be used for maximum flexibility in the system architecture. Comes as a reference implementation of a Contracts Dependencies Registry EIP.

• Added preset with ownable functionality - OwnableContractsRegistry.

contracts-registry/pools

• Added PoolContractsRegistry module, which is designed for convenient deployment of pool contracts of different types using a BeaconProxy factory. The module leverages the ContractsRegistry functionality by making the pools upgradeable and dependable.

• Added preset with ownable functionality - OwnablePoolContractsRegistry.

diamond

• Added Diamond facet module, which provides the custom implementation of the Diamond proxy EIP.

• Added facet with ownable functionality - OwnableDiamond.

libs

arrays

• Added ArrayHelper library, which implements a number of functions for working with arrays: reverse,asArray, insert.

• Added Paginator library for convenient contracts pagination.

• Added SetHelper library to ease work with OpenZeppelin EnumerableSet, as well as StringSet from this repository.

data-structures

• Added StringSet library which is based on OpenZeppelin sets.

decimals

• Added DecimalsConverter library, which allows you to convert numbers to different precisions. For example, it is good for converting ERC20 tokens with different decimals.

math

• Added DSMath library, which implements the function of exponentiation with accuracy.

utils

• Added a Globals file that contains various useful constants.
