Project Overview

"The Creditcoin ecosystem is a blockchain-based infrastructure that enables secure, transparent, and verifiable financial and decentralized applications. It includes the Creditcoin blockchain network and a suite of dApps developed by Gluwa. Core components include:

  • Creditcoin Blockchain Network: the base layer for transaction verification, smart contracts, and coordination
  • Penguinbase: a platform for gaming, airdrops, and ecosystem engagement
  • Spacecoin: a DePIN network leveraging Creditcoin to enable global, crypto-powered permissionless internet access
  • Other Gluwa-developed dApps: additional applications extending financial, identity, and coordination use cases

The bug bounty covers both on-chain and off-chain components across the ecosystem:

  • Smart contract logic (e.g., state management, permissions, and value flows)
  • Blockchain interactions and state transitions
  • Off-chain systems (e.g., APIs, coordination services, key managmeent and operational infrastructure)
  • Cryptographic mechanisms (e.g., signatures, identity and proof generation)
  • Economic and incentive models (e.g., rewards, payments, reputation and slashing echanisms)
  • Cross-system interactions between on-chain and off-chain components

Researchers should pay special attention to:

  • Trust boundaries between components
  • State inconsistencies and race conditions
  • Authentication and authorization flows
  • Economic exploits and incentive misalignment
  • On-chain and off-chain intersections, especially involving incentives, identity, and coordination"
