Use Cases

CrossFi Chain is a Layer-1 blockchain that addresses key challenges in decentralized finance (DeFi) and financial accessibility through its modular architecture. The platform combines Cosmos SDK for consensus and EVM compatibility for smart contracts, providing applications across various sectors from Web3 banking to AI infrastructure.

Web3 Banking & Real-World Payments​

Daily Payment Solutions​

CrossFi App enables cryptocurrency usage in everyday transactions through CrossFi Cards - Visa-compatible payment cards.

Real-World Applications:

  • Shopping at 100 million locations worldwide
  • ATM cash withdrawals in 90+ countries
  • Online purchases and bill payments
  • International money transfers without traditional banking

Technical Implementation​

CrossFi Cards operate through automatic XFI-to-fiat conversion at point-of-sale using the XFI utility token.

System Features:

  • Non-custodial fund control through smart contracts
  • 1.7%-2.2% transaction fees (varies by country/amount)
  • Integration with Apple Pay and Google Pay
  • Real-time conversion rates via price oracles

Decentralized Finance Infrastructure​

XFI-MPX Dual Token System: Participate in network security through Delegated Proof of Stake mechanism via the Native Staking Protocol.

  • MPX Token: Governance token used for voting on network proposals and enabling XFI staking
  • Validator Delegation: Delegate MPX to validators via XFI Console to earn staking rewards
  • Network Security: Validators secure the network using Tendermint consensus with ~5 second finality
  • Governance Participation: Vote on protocol upgrades and treasury proposals using MPX tokens

Synthetic Assets & Global Markets​

Market Access Without KYC​

xAssets platform provides access to traditional financial markets through blockchain-based synthetic assets.

Available Markets:

  • Equity Indices: Trade synthetic S&P 500, NASDAQ through smart contracts
  • Commodities: Access gold (xXAU), silver, and oil derivatives 24/7
  • Forex Pairs: Trade major currency pairs without traditional brokers
  • Individual Stocks: Synthetic versions of major company shares (xAAPL, xTSLA)

Risk Management System​

Collective Debt Pool mechanism distributes trading risks across all platform participants.

Safety Mechanisms:

  • Health Factor Monitoring: Real-time calculation prevents position liquidations
  • Oracle Price Feeds: Chainlink-based price data ensures accuracy
  • Automated Liquidations: Smart contract execution protects system solvency
  • Burn Mechanism: Token burning during swaps reduces overall system debt

  • Health Factor: Ratio of collateral value to debt value; values below 1.0 trigger liquidation

Cross-Chain Interoperability​

Multi-Blockchain Asset Management​

XFI Bridge utilizes deBridge protocol - a decentralized infrastructure with 25+ security audits and $200K bug bounty program.

  • Ethereum: Access to largest DeFi ecosystem with $50B+ TVL
  • BNB Smart Chain: Low-cost transactions for high-frequency trading
  • Polygon: Layer-2 scaling solution with sub-second confirmations
  • Arbitrum: Optimistic rollup technology for reduced gas costs
  • Base: Coinbase's Layer-2 network built on Optimism stack

  • Minimum 1,000,000 MPX self-delegation (1 MPX)
  • Nearly 100% uptime to avoid slashing penalties
  • Secure infrastructure with DDoS protection
  • Technical expertise for node management

Network Infrastructure​

CrossFi Chain Architecture provides enterprise-grade blockchain infrastructure.

Technical Specifications:

  • Tendermint consensus with ~5 second finality
  • Maximum 64 active validators (expanding to 128)
  • 5% slashing penalty for validator misconduct
  • Automated unjailing and restaking mechanisms

Complete Node Operation: From initial setup to validator maintenance.

Ecosystem Integration & External Connectivity​

How CrossFi Connects to External Ecosystems​

CrossFi Chain's modular architecture enables seamless integration with major blockchain networks:

Ethereum Ecosystem​

Direct Integration via EVM Layer:

  • Deploy existing Ethereum dApps without code changes
  • MetaMask and Web3 wallet compatibility
  • Access to Ethereum's DeFi protocols through bridge
  • Smart contract state migration support

Cosmos Network​

IBC Protocol Integration:

  • Connect to 50+ Cosmos zone blockchains
  • Atomic cross-chain transactions
  • Shared security through Tendermint consensus
  • Cosmos SDK module compatibility

Cross-Chain Asset Transfer Process:

  1. Asset Locking: Tokens locked in source chain smart contract
  2. Validator Consensus: 2/3 BFT threshold confirmation required
  3. Wrapped Token Minting: 1:1 wrapped tokens issued on destination chain
  4. Reverse Process: Burn wrapped tokens to unlock original assets

CrossFi Chain provides the infrastructure for next-generation financial applications through its unique combination of Cosmos scalability, EVM compatibility, and comprehensive DeFi tooling. Each component works together to create a unified ecosystem where traditional finance meets decentralized innovation.
