RSK + API3 bounty: Enable p2p transfers on RSK network + use API3 price feeds

Prize Bounty

$0.1627 RBTC (equivalent to 4000USD)

Assigned reviewers: @Ashar2shahid, @camronh, @jgcogsystematictrading, @shenshin, and @bguiz

Challenge Description

p2plnbot is a Telegram bot which allows people to trade with other people using telegram over the lightning network - github.com/grunch/p2plnbot.

The base task:

Fork the p2plnbot such that it works on RSK. This bot must be able to:

• Enable peer-to-peer transfers between RSK network accounts of RBTC.
• Enable peer-to-peer transfers between RSK network accounts of whitelisted ERC20 tokens. This whitelist must include RBTC and RIF.
• (Optional) Enable transfers between RSK network accounts using RNS addresses (e.g. *.rsk), in addition to standard addresses (0x…)

The fair market price task:

• The bot currently requires the seller to manually input the price in a p2p trade
• Instead of this, use price feeds from API3 to query the current price for the trade
• Display this as “fair market price” within the bot, however the seller may still override it
• The buyer should be able to see both the seller’s price and the fair market price

Submission Requirements

The base task:

• The code must be publicly visible in a repo on github.com
• The repo must be licenced with one of the following open source licences: GPL-3.0, or MIT
• The submission must maintain the baseline functionality of, and support features of, the p2plnbot
  • apart from switching from LN to RSK, if any features need to be removed, please clarify with the reviewers first.
• The bot must have a live deployment, and the @-name of the bot must be included in the README within the repo
• Record a video (screen capture) demonstrating the use of the Telegram bot
• Any smart contracts used must be live on an RSK public network, either RSK Testnet or RSK Mainnet; localhost and/or RSK Regtest is insufficient

The fair market price task:

• The fair market price feature must make use of the price feeds from API3
  • Trades occurring on this bot should use RSK Testnet or RSK Mainnet (your choice)
  • Prices displayed in this feature of the bot should access the RBTC and RIF API3 price feeds available on RSK Mainnet only
• API3 price feeds for RBTC and RIF on RSK Testnet are available using the following Beacon IDs:
  • RBTC/BTC: 0x4aaf6e2ef7fc8280aa99d321e53ef2e4f111b7805677a262eb5882b1a27b5108

  • RIF/USD: 0x3c7ba811cb33ad3784389a580af1a657ce0ebd701b1eb415eafabe5a4885e92f

• API3 price feed for RBTC and RIF are not available on RSK Mainnet for the purposes of this bounty.
• To access prices feeds:
  • Use the API3 readDataFeedWithId() method.
  • Use the API3 readDataFeedValueWithId() method.
  • For your convenience, a demo repo is available, which demonstrates how to do this.
