Bridge Operations

Execute cross-chain transfers with optimal bridge selection and cost efficiency.

Bridge Operation Example

const bridge = await difract.crossChain.bridge({
    asset: "USDC",
    amount: "10000",
    from: {
        chain: "ethereum",
        address: "0x1234...5678"
    },
    to: {
        chain: "polygon",
        address: "0x9abc...def0"
    },
    options: {
        bridgeSelection: "auto",  // or specific bridge
        optimization: {
            gas: true,
            time: true,
            security: true
        },
        maxSlippage: 0.5,  // %
        maxGas: 100        // GWEI
    }
});

Cross-Chain Yield Comparison

Compare yield opportunities across different networks to optimize returns.

Yield Comparison Example

const comparison = await difract.crossChain.compareYield({
    asset: "USDC",
    amount: "50000",
    chains: [
        "ethereum",
        "polygon",
        "arbitrum",
        "optimism"
    ],
    protocols: {
        lending: ["aave", "compound"],
        dex: ["uniswap", "curve"]
    },
    metrics: {
        apy: true,
        tvl: true,
        risk: true,
        gas: true
    },
    filters: {
        minApy: 5,        // %
        maxRisk: 7,       // score
        minTvl: "1000000" // USD
    }
});

Cross-Chain Portfolio Rebalancing

Automatically rebalance your portfolio across different chains for optimal performance.

Portfolio Rebalancing Example

const rebalance = await difract.crossChain.rebalance({
    portfolio: "portfolio_123",
    target: {
        ethereum: 40,   // %
        polygon: 30,    // %
        arbitrum: 20,   // %
        optimism: 10    // %
    },
    constraints: {
        maxSlippage: 1,    // %
        maxGas: 150,       // GWEI
        minReturn: 0.1     // %
    },
    execution: {
        mode: "batch",     // or "sequential"
        priority: "medium",
        gasOptimization: true
    },
    safety: {
        maxLoss: 2,        // %
        pauseOnVolatility: true
    }
});

Cross-Chain Gas Optimization

Optimize gas costs for cross-chain operations across different networks.

Gas Optimization Example

const gasStrategy = await difract.crossChain.optimizeGas({
    operations: [
        {
            type: "bridge",
            from: "ethereum",
            to: "polygon",
            asset: "USDC",
            amount: "10000"
        },
        {
            type: "swap",
            chain: "polygon",
            from: "USDC",
            to: "MATIC",
            amount: "5000"
        }
    ],
    strategy: {
        mode: "aggressive",  // or "balanced", "conservative"
        maxWaitTime: "1h",
        targetGas: {
            ethereum: 50,    // GWEI
            polygon: 100,    // GWEI
            arbitrum: 0.1    // GWEI
        }
    },
    notifications: {
        gasThresholds: true,
        executionUpdates: true
    }
});

Cross-Chain Security

Implement security measures for cross-chain operations.

Security Configuration Example

const security = await difract.crossChain.configureSecurity({
    bridges: {
        whitelist: ["hop", "across", "stargate"],
        riskThreshold: 7,
        auditRequirement: true
    },
    transactions: {
        maxValue: "100000",    // USD
        approvalTimeout: "15m",
        confirmations: {
            ethereum: 12,
            polygon: 256,
            arbitrum: 64
        }
    },
    monitoring: {
        bridgeHealth: true,
        networkStatus: true,
        alertThresholds: {
            delay: "30m",
            failure: 3
        }
    },
    recovery: {
        autoRetry: true,
        fallbackBridges: true,
        emergencyWithdraw: true
    }
});
