A factory library that deploys payment splitting contracts

Spurious Dragon EraVerified Source

Historical Significance

Part of a 2016 attempt to sell working organisations as deployable parts: a governance contract, a token or a payment splitter bought from a counter for a fee, with the created contract's shape published on chain beside it.

Context

Deployed in the Homestead era, when deploying a contract meant compiling one yourself.

Description

CreatorSplitter is a factory library in Airalab's DAO toolkit. Its create function deploys a Splitter, a contract that divides everything sent to it between a list of recipients by share, so an organisation can route income without a human step. Deployed on 23 November 2016 by 0x4af013afbadb22d8a88c92d68fc96b033b9ebb8a and recovered from airalab/core.
