Gas Optimization Techniques

Loopify Finance achieves up to 95% gas savings through advanced optimization techniques and zero-fee flash loans.

Key Optimizations​

Zero-Fee Flash Loans​

We use Balancer and Morpho Blue for zero-fee flash loans:

// Zero-fee flash loan from Balancer
function flashLoan(address asset, uint256 amount) external {
    IBalancerVault(BALANCER_VAULT).flashLoan(
        IFlashLoanRecipient(this),
        tokens,
        amounts,
        userData
    ); // No fees charged
}

Transaction Batching​

Multiple operations combined into single transaction:

Before Optimization:

  • 5 separate transactions = ~225,000 gas
  • Individual approvals, deposits, borrows

After Optimization:

  • 1 batched transaction = ~55,000 gas
  • All operations combined atomically

Euler V3 (EVC) Integration​

Batch operations using Euler's Ethereum Vault Connector:

// EVC batch execution
function batchExecute(Operation[] calldata ops) external {
    for (uint i = 0; i < ops.length; i++) {
        _execute(ops[i]);
    }
    _checkAccountStatus(); // Single status check at end
}

Smart Contract Optimizations​

Gas-Efficient Patterns:

  • Custom errors instead of strings
  • Packed structs for storage efficiency
  • Assembly optimizations for critical paths
// Custom errors save ~50% gas vs require strings
error InsufficientBalance(uint256 requested, uint256 available);

Performance Metrics​

Gas Savings Comparison​

OperationTraditionalLoopifySavings
Basic Loop$120-180$0.7575%
Advanced Strategy$200-500$0.7595%
Multi-Protocol$300-600$0.7588%

Transaction Optimization​

Manual Execution:

  • 10-15 separate transactions
  • $400-500 in gas fees
  • 2-3 hours of active management

Loopify Execution:

  • Single transaction
  • $0.75 average cost
  • 2 minutes setup time

Technical Implementation​

Batch Operation Engine​

Combines identical operations across user portfolios:

// Operation merging for efficiency
function mergeOperations(
    address[] memory vaults,
    uint256[] memory amounts
) internal pure returns (
    address[] memory uniqueVaults,
    uint256[] memory totalAmounts
) {
    // Merge duplicate vault operations
    // Reduces gas by eliminating redundant calls
}

Flash Loan Optimization​

Strategic use of multiple providers for zero fees:

  • Balancer: Primary (0% fees)
  • Morpho Blue: Backup (0% fees)
  • Automatic Selection: Chooses optimal provider

These optimizations enable Loopify to deliver institutional-grade strategies at retail-friendly costs, transforming expensive DeFi operations into accessible single-click experiences.
