Work Built Around Real Systems

Representative case-studies showing the kinds of complex engineering work Libélula Software undertakes.
Multi-Blockchain Token Bridge
  • Python
  • Workflow Architecture
  • Fault Tolerance
  • Extensibility

Built a configurable bridge framework connecting Ethereum with two proprietary blockchains so their native currencies could be represented and used in Ethereum's broader DeFi ecosystem.
