This contract is implementing a matching donation crowd funding.

The main idea is to encourage donations by matching incoming donations and thus doubling the donations of the public.

In order to encourage the public to donate we have deposited to the contract wallet 1 million NIS worth of ETH.

Any donation that will be received to the contract will be transferred to the donation beneficiery by the contract. And in addition the donation will be matched by the contract and the same amount of donation will be tranfered to the beneficiery fro mthe pre loaded amount.

So that for every X ETH donated the contract will transfer another X ETH.

The max total of matched donations cannot exceed the deposited amount. The owner can deposit more funds into the contract in order to increase his matching donations.

If the deposited amount is exhausted, donations are still welcome and will be transferred to the beneficiary without the contract matching.

The donation contract has been deployed to 0x0236DA65D76Ae844aBB81814CeBB6fe9B001d587
