Overview

Darex revolutionizes DeFi by enabling single-transaction, cross-asset deposits to any lending protocol. Here’s how we make it possible.

​
Security Features

Atomic Execution

All steps succeed or fail together - no partial state

Reentrancy Protection

All external calls protected with reentrancy guards

Slippage Control

User can specify max slippage for swaps

Access Control

Only authorized adapters can register instruments

​
Gas Optimization

Darex is optimized for minimal gas costs:
  • Packed Storage: Instrument IDs encode chain ID + protocol data in 32 bytes
  • Single Transaction: All operations in one tx (no approve + deposit sequence)
  • Minimal Lookups: O(1) instrument and pool queries
  • Efficient Swaps: Leverages Uniswap V4’s efficient swap routing
Average gas cost: ~180k gas for deposit with swap vs ~300k gas for manual swap + approve + deposit
