Splitter Smart Contract - B9Lab Course Practice

Overview:

You will create a smart contract named Splitter whereby:

• there are three people: Alice, Bob and Carol
• we can see the balance of the Splitter contract on the web page
• whenever Alice sends ether to the contract, half of it goes to Bob and the other half to Carol
• we can see the balances of Alice, Bob and Carol on the web page
• we can send ether to it from the web page

Stretch goals:

• add a kill switch to the whole contract
• make the contract a utility that can be used by David, Emma and anybody with an address
• cover potentially bad input data

Implementation:

The following implementation choices has been made not explicitly required by spec:

• explicit check on payer for splitting, no one else can call split
• withdraw pattern for splitted payments
• free contribution with fallback function also for payer

Limitations:

The following limitations currently apply:

• no check for arithmetic overflow
• no web page
