Cross-Chain Guide

Master cross-chain operations on DI Network, including asset bridging, gasless transactions, and multi-chain strategies.

Cross-Chain Overview

DI Network operates across multiple blockchains:

• Ethereum: Main hub with full functionality

• Polygon: Low-cost transactions and high throughput

• Arbitrum: Ethereum L2 with reduced fees

• BSC: Binance Smart Chain integration

• Avalanche: High-performance blockchain support

Getting Started

Multi-Chain Setup

1. Configure Networks: Add supported chains to your wallet

2. Fund Accounts: Ensure native tokens for gas on each chain

3. Bridge Assets: Move tokens between chains as needed

4. Optimize Strategy: Choose chains based on activity type

Network Selection Strategy

Chain	Best For	Gas Costs	Speed
Ethereum	Large transactions, governance	High	Medium
Polygon	Frequent trading, small amounts	Very Low	Fast
Arbitrum	DeFi activities, medium amounts	Low	Fast
BSC	Alternative ecosystem access	Low	Fast
Avalanche	High-performance trading	Medium	Very Fast

Cross-Chain Features

Asset Bridging

Move tokens seamlessly between supported chains:

• Native Tokens: DI, DUSD bridge natively

• Wrapped Assets: Bridged versions maintain functionality

• Liquidity: Unified liquidity across chains

• Governance: Cross-chain voting capabilities

Gasless Transactions

Execute transactions without native tokens:

• Gas Credits: Pre-purchased transaction credits

• Meta Transactions: Relayer-executed transactions

• Sponsored Transactions: Protocol-covered gas costs

• Batch Operations: Multiple actions in single transaction

Unified Experience

• Single Interface: Manage all chains from one dashboard

• Cross-Chain Positions: View portfolio across networks

• Automated Routing: Optimal chain selection for operations

• Synchronized State: Real-time cross-chain updates

Multi-Chain Strategies

Chain Specialization

Ethereum Strategy:

• Large DI token staking positions

• Governance participation

• High-value transactions

• Long-term holdings

Polygon Strategy:

• Active trading and arbitrage

• Frequent position adjustments

• Small-amount experiments

• Daily DeFi activities

Arbitrum Strategy:

• Medium-sized liquidity provision

• Perpetual trading positions

• Regular rebalancing

• Cost-efficient operations

Cross-Chain Arbitrage

Price Differences:

Opportunity Example:
Ethereum DI Price: $10.05
Polygon DI Price: $9.95
Arbitrage Profit: $0.10 per DI (1%)
Bridge Cost: $0.02 per DI
Net Profit: $0.08 per DI (0.8%)

Execution Strategy:

1. Monitor prices across chains

2. Identify profitable opportunities

3. Execute trades on cheaper chain

4. Bridge assets to expensive chain

5. Sell for profit

Yield Optimization

Chain-Specific Yields:

Yield Comparison:
Ethereum DI Staking: 15% APY
Polygon DI Staking: 22% APY (incentivized)
Arbitrum LP Mining: 35% APY (new program)
Strategy: Allocate based on risk-adjusted returns

Best Practices

Security Considerations

• Verify bridge contract addresses

• Use official bridge interfaces only

• Start with small test amounts

• Monitor bridge transaction status

• Keep emergency funds on each chain

Cost Optimization

• Batch Operations: Combine multiple actions

• Timing: Bridge during low congestion

• Route Selection: Use most efficient paths

• Gas Tokens: Maintain native tokens for fees

Risk Management

• Bridge Risk: Understand bridge security models

• Timing Risk: Account for bridge delays

• Liquidity Risk: Ensure adequate liquidity

• Regulatory Risk: Consider jurisdiction differences

Integration Tips

Wallet Configuration

Add network configurations for all supported chains:

// Example network configurations
const networks = {
  ethereum: {
    chainId: 1,
    rpcUrl: 'https://mainnet.infura.io/v3/...',
    blockExplorer: 'https://etherscan.io'
  },
  polygon: {
    chainId: 137,
    rpcUrl: 'https://polygon-rpc.com',
    blockExplorer: 'https://polygonscan.com'
  }
}

Cross-Chain Monitoring

Track positions across all chains:

• Portfolio aggregation tools

• Cross-chain transaction tracking

• Multi-chain yield monitoring

• Unified performance analytics

Troubleshooting

Common Issues

Bridge Delays: Transactions taking longer than expected Failed Transactions: Bridge operations not completing Balance Discrepancies: Tokens not appearing on destination High Fees: Unexpected bridge costs

Solutions

• Check bridge status and congestion

• Verify transaction confirmations

• Allow time for finalization

• Contact support for stuck transactions

Future Developments

Planned Features

• Additional chain integrations

• Enhanced cross-chain governance

• Improved bridge efficiency

• Native cross-chain contracts

Staying Updated

• Follow multi-chain roadmap

• Participate in cross-chain governance

• Test new chain integrations

• Provide feedback on user experience
