Vether BURN Contract

Vether Burn Contracts will allow members to deposit Ether, then for other people to automate the daily burning process.

Member

Simply call deposit(days) with an attached amount of Ether, and the number of days to burn over.

Burners

In order to claim the fee of 1%, call burn() on the contract. This will

1. Burn for everyone on the current day
2. If vether is available for yesterday, it will withdraw it
3. Pay out everyone who burnt yesterday
4. Pay you the 1% fee

Note: burn() can only be called once a day, so it's a race once a new day starts.

Smart Contract

Vether Burn has the following intended design:

Users

• Deposit Ether to burn over several days

Burners

• Burn and Withdraw on behalf of other people for a fee

Limits There is a maxEther maxMembers maxDays to limit liability on the contract initially.

Testing - Buidler

The test suite uses Buidler as the preferred testing suite, since it compiles and tests faster. The test suite implements 7 routines that can be tested individually.

npx buidler compile

Execute all at once:

npx builder test

Or execute individually:

npx builder test/1_coin.js

Testing - Truffle

Truffle testing can also be done:

truffle compile && truffle migrate --reset

Execute all at once:

truffle test

Or execute individually:

truffle test test/1_burn.js
