Etherparty's Smart Contracts

V1

Crowdfund creator

V1

Here is a list of all requirements needed for the token creator contract

• ERC20 Compatible

• Fixed total supply

• Dynamic token allocation (less than or equal to 10)

• Dynamic pricing rounds (less than or equal to 10)

• Possibility to Burn unsold tokens or Move tokens to a known address (move allocation with 0 address as _to)

• Possibility to schedule and reschedule your crowdfund.

• Dynamic Vesting period

• Presale seeding function

User stories

• A user can create a token contract to their spec (Name, Symbol, Total Supply) and it needs to be ERC20 compatible

• A user can setup multiple token allocations sending it to multiple addresses. Every token allocation is a percentage of the total supply. The sum of all allocations is the total supply

• A user is able to hold a presale off platform and send the tokens to a batch of addresses

• A user is able to setup multiple pricing rounds. All of these pricing rounds have both a RATE and an EPOCH

• Tokens should be locked for the duration of the crowdfund. Unlocked as soon as the crowdfund closes (or is done?)

• A user should be able to decide where the leftover tokens from the crowdfund are sent. Either they are going to an address or are burnt

• A user should be able to schedule his crowdfund and reschedule it (rescheduling only can occur 4 hours before intended crowdfund start time)

• A user should be able to create multiple allocations for his tokens, and every allocation should be able to vest for a variable amount of months.
