So now that we have a way of getting Ether in and out of a contract, we need to incorporate this into an ERC20 Token and we will almost be there, I say almost because adding extra functionality is a complex subject we will cover in future notes.

Our new token will have an unlimited supply, will be able to receive Ether and give back tokens, and of course the owner will be able to retrieve the Ether, it will also be an ERC20 Token, our contract will mint these tokens which I am calling blips.

A1 and A2 now have exchanged some ether for Blips and the BLIPS token contract has an ether balance, the total supply has also increased to reflect that. So we issued our blips tokens in exchange for something and we received some ether, now all we need to do is retrieve said ether and exchange it for fiat or products. To do so, we will use the collect function we covered in the tip jar example, it is identical:. The only thing that changes is that as the owner of the token you need to add it as custom contract or interact with it via web3 to have access to the collect function.

We will try the first option, note all the extra information we get:. And now we have access to the collect function:. The owner account is the only one allowed to collect like in our tip jar example, trying to collect from another account would result in an error it will throw an exception, no collection will happen and some gas will be lost.

Notes on getting started Part 8. A big note about ICOs: Funding any project is usually not a pleasant or smooth event, so the idea of crowdfunding via token sales is an appealing experiment no more asking banks, vc's, rich relatives, etc,etc ,at the same time the relative ease and low cost by which you can make a token has resulted in thousands of ICOs, so there is now the added cost of sorting through them as an investor or user.

Which ones are good and which ones are bad is a matter of due diligence and personal choice,each one of us needs to decide if we feel comfortable giving money to a project that might or might not work as intended with the available information. Further complicating things there are legal matters depending on which country you live, in some countries ICOs are banned, in others they could be considered stocks if they pay dividends and then fall under that regulatory umbrella and in others they are allowed or overlooked for now.

Getting Paid in contracts. The payable keyword allows a function to receive ether, it is a modifier which we reviewed in the previous notes, and can be applied to other functions. After adding the contract to parity, no more warnings are displayed and we can now send Ether, the transaction goes ahead and the token itself will now show an ether balance, everything is great except for one crucial detail: We can send ether into a contract, but how would we get it out again and exchange it for goods in ETH or exchange it for fiat currency?

We can't, it is possible, but not with this contract, hence the contract name, we have created a black hole for Ether, those 0. While this is only test ether with no monetary value just sentimental if you send real ether to a contract and it has a payable fallback function you have just trown money into a black hole. Getting ether out of the tip jar: This is the id for main network.
