Overview of HOPR transfers on Ethereum and the bridge

[QYuQianchen]

The following is an issue for bounty, meant for external contributors to pick up and work on the analytics of HOPR tokens. Click here to check all the bounties and here to check all the open positions at HOPR.

Introduction

Recently our community has launched a three-phase token distribution on xDai chain and Ethereum blockchain at the end of February 2021. More than 30,000 of transactions were generated from various decentralized exchanges (DEX) since the launch. The HOPR token was even ranked as one of the top 20 tokens by trading volume on CoinMarketCap.

From the vast public data, we want to get a better understanding of HOPR trading activities. We invite you to explore the public Ethereum and xDai chain and provide answers to the following questions with source code and visualizations.

HOPR token was deployed on Ethereum mainnet on the 19th Feb. Shortly after the deployment, 85 million HOPR were minted for the token launch. 50 million out of the 85 million were pre-sale (1st phase of token launch) tokens that were bridged to xDai chain for HOPR Genesis DAO members to purchase. HOPR Genesis DAO members are accounts that hold gHOP tokens. Those presale tokens have a locking period until almost the end of the Balancer LBP sale (2nd phase of token launch). DAI collected from presale and the remainder of pre-sale tokens were bridged back to Ethereum mainnet to be put into the Balancer LBP sale pool, together with the 30 million HOPR tokens planned for the 2nd phase of token launch. Towards the end of the LBP sale, pre-sale tokens were unlocked on the xDai chain. All the DAI and HOPR staying in the LBP pool were transferred to Uniswap for the 3rd phase of token launch. Those tokens were the initial liquidity providers for the HOPR/DAI pair. This pool remains open.

Besides the 85 million token launch, there are around 13.3 million circulating HOPR tokens later minted for bounties (bridged to xDai) and 31.9 million tokens minted for treasury.

Some analytics has been done for the LBP sale part of HOPR token launch. See the dashboard here.

Task Description

Due to the cross-chain nature of HOPR tokens (living both on Ethereum mainnet and xDai chain), we would like to gain a bird view on the HOPR token transfers on both chains:

1. Visualize life-cycle (provenance) of HOPR in a network graph: a. Minting b. Transfer c. Burning
2. Visualize the cross-chain xHOPR and HOPR conversion, by combining the previous two visualizations together.

A bounty on analysis of xHOPR can be found here.

Definition of complete

• [x] A working Nodejs project or python project or with another data analytics platform (e.g. DuneAnalytics/BigQuery) that contains scripts/queries that extracts HOPR transfers on Ethereum mainnet and xDai chain. Instruction on installation and running should be well-documented.
• [x] Visualize HOPR token transfers in two network graphs, where a node represents an Ethereum address and a directional edge denotes a token transfer. The amount of tokens being transferred and the timestamp of the transfer is labeled on the edge.
  • [x] One network graph for HOPR on Ethereum chain.
  • [x] A combined graph of both Ethereum and xDAI chains, as if no bridge existed. E.g. a Mint event on xDai (from 0x to recipient) is associated with a Transfer event (from sender to bridge) on ETH. In this graph, it should be projected as a transfer from sender to recipient.
• [x] The network graph is interactive, where:
  • [x] All the token transfers associated with an account are highlighted when clicking on a node.
  • [x] Sender and recipient of the transfer is highlighted when clicking on an edge. Ideally, all the succeeding token transfers associated with a given token transfer is also highlighted.

Work has been started.

These users each claimed they can complete the work by 265 years, 6 months from now. Please review their action plans below:

1) rade212142 has applied to start work _(Funders only: approve worker | reject worker)_.

Fyhgujaha usoshsish hsisosheh udishwhso heiebsuei 2) abdul-basit612 has applied to start work _(Funders only: approve worker | reject worker)_.

I will take determination and dedication to complete this task on time 3) controlcpluscontrolv has applied to start work _(Funders only: approve worker | reject worker)_.

I can do this in python fairly quickly using some data analytics libraries, can do this as a standalone app or web app depending on whichever you prefer 4) niklr has been approved to start work.

I recently discovered the HOPR network, got hooked since and now would like to contribute. As far as I know DuneAnalytics does not offer network graphs as visualization option and BigQuery is very limited in terms of free usage. Therefore, I would deliver a Nodejs project using d3/cytoscape in combination with Angular. It should be feasible to submit my work within a few days upon being approved. Due to the similar fashion I would also like to apply for "Overview of HOPR transfers on xDai" if possible. 5) pangkung099 has applied to start work _(Funders only: approve worker | reject worker)_.
