Query: Jack The Rippler: Arbitrage on the Decentralized Exchange of the XRP
  Ledger   The XRP Ledger (XRPL) is a peer-to-peer cryptographic ledger. It features a
decentralized exchange (DEX) where network participants can issue and trade
user-defined digital assets and currencies. We present Jack the Rippler, a bot
that identifies and exploits arbitrage opportunities on the XRPL DEX. We
describe Jack's arbitrage process and discuss risks associated with using
arbitrage bots.
