Duperchat

A Smart Contract on Ethereum for donations where the donators can also leave a message to the receivers. Messages are stored in IPFS.

Donate Contract

For now, the person that deploys the contract is the owner of the contract.

Public Methods

Returns the balance the contract contains (in native currency):

getTotalBalance()

Returns the total messages the contract received:

getTotalMessages() uint

Get the message based on a position in the array. The current POC is saving messages on IPFS. The message in the array will be an address from IPFS pointing to the content of the message.

getMessage(uint index) string

Send a message via the Payable function, with the amount you want to donate.

sendMessage(string message)

Owner Methods

To withdraw the balance from the contract to the owners's address

withdrawBalance()

Next Steps:

• Create a contract that creates Donate contracts and uses aliases to find them
• Increase security or remove in Donate.setOwner
• Contract pause
• On withdraw, send a percentual to the main contract
• Create a Proxy Contract
• Cleanup frontend POC
• Actions for build and deploy frontend
