Includes the ERC-20 token contract that models surrogate fuel tokens which will be replaced by Holo's final implementation on Holochain.","language":"JavaScript","stars":22,"topics":["holochain","blockchain","token","erc20-token","ico","holo-fuel","holo","hot-token"],"license":null,"category":"blockchain-web3","readme_excerpt":"Holo contracts This repository holds the three smart contracts that constitute the on-chain part of Holo's pre-sale of hosting credit (Holo Fuel) in which an ERC-20 token on Ethereum (\"HoloToken\") acts as a surrogate for Fuel until Holo launches on its own Holochain network - at which point Holo will redeem (and burn) tokens for real Holo Fuel. 1. HoloSale: a limited time period contract that accepts purchase requests for HoloToken and handles those requests, according to the supply available. 2. HoloToken: an ERC20 contract that mints Holo tokens (that act as surrogate for ) during the sale period and can destroy tokens in the later phase, when they are converted to Holo Fuel once the Holo network launches. 3. HoloWhitelist basically a mapping of addresses to a whitelist flag. It also stores number of reserved tokens per day for funders who proved to be an active part of the ecosystem (developer or host). Audit This code was audited by one up in December 2017. The review was published here. Context Holo will be pre selling its hosting credits (Holo Fuel) at a fixed price and with a dynamic cap in the form of an ERC20 token that acts as a surrogate for hosting credits that we will provide as a Holochain app once the Holo network has launched. A set of coordinated Ethereum contracts manage the supply and purchase of these tokens over the sale period. Design Principles 1. We take a strategy of splitting the contracts as small logical units as possible and to re-use as much code","default_branch":null,"files":null,"tree":[],"storefront":"/r/Holo-Host","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Holo-Host/ico/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
