Introduction - Darex Documentation

What is Darex?

Darex is a Universal DeFi Instrument Registry & Atomic Router that provides:

Universal Instrument Identifiers: Unique IDs for every DeFi instrument
Atomic Routing: Single-transaction execution of multi-step DeFi flows (swap → deposit)

What is an Instrument?

In Darex, an instrument represents a specific DeFi position. It’s the combination of:

Protocol - Where you deposit (Aave, Compound, Morpho, Moonwell)
Asset - What you deposit (USDC, EURC, DAI, etc.)
Blockchain - Where it lives (Base, Ethereum, etc.)

Example: “Aave USDC on Base” is one instrument. “Compound USDC on Base” is a different instrument - same asset, different protocol. Each instrument has a unique ID that works everywhere:

0x00002105c053a3e1290845e12a3eea14926472ce7f15da324cdf0700056fc04b

This ID lets you query yields, compare options, and execute deposits without knowing the underlying protocol details.

The Problem We Solve

Today, DeFi has thousands of instruments but no universal way to identify or compare them:

Multi-step workflows (swap → approve → deposit) are complex and error-prone
Each protocol requires custom integration (Aave vs Morpho vs Compound)
No universal identifiers for comparing yields across chains/protocols
Institutions and AI agents can’t operate at scale without standardization

The Solution

Darex enables one-click deposits to any lending protocol:

User sends USDC → Darex automatically:
  1. Detects target token (e.g., EURC)
  2. Swaps USDC → EURC invisibly
  3. Deposits EURC to protocol (e.g., Aave)
  4. Returns yield tokens (e.g., aEURC)
All in ONE atomic transaction ✅
