solidity-structure

Overloading of some OpenZeppelin contracts to add a ready-to use structural behaviors and interactions between contracts.

why

Because the old OpenZeppelin 2.5.1 contracts are not compatible with the latest solidity and I am in need of some contracts to create a crowdsale for a token... Then I ended up upgrading it all and decided to share it with the world.

known limitations

Very limited access control. You must implement your own access control for the crowdsale if you want to use full OpenZeppelin 4.x.x access control features.

how to use

Directly override the contract you want to use, functionallity is the same as the old OpenZeppelin versioned contracts.

The contracts are:

└-contracts
	|-abstractions
	|	|- finalizable.sol: extension where a contract can be finalized.
	|-context
	|	|- pausable.sol: extension where a contract can be paused.
	|	|- refundable.sol: extension where a transacton can be refunded by Escrow.
	|	└- secondary.sol: used as secondary Context. 
	|-math
	|	└- SafeMath.sol: old safe math library. 
	|-security
	|	└- reentrancyGuard.sol: extension that adds reentrancy guard modifier. 
	|-tokens
	|	|- burnable.sol: ERC20 burnable token utility with roles applied.
	|	└- mintable.sol: ERC20 mintable token utility with roles applied. 
	└-utils
	 	└- escrow
			|- conditionaEscrow.sol: conditional escrow abstraction.
			|- escrow.sol: escrow base contract.
	 		└- refunEscrow.sol: refund escrow.
