What is the Instrument Registry?

The InstrumentRegistry is a universal catalog that assigns unique identifiers to every DeFi position across all chains and protocols. Think of it as the DNS of DeFi: Just like DNS maps domain names to IP addresses, the Instrument Registry maps instrument IDs to protocol adapters.

​
What is an Instrument?

An instrument in Darex represents a specific DeFi position - a place where you can deposit assets into a protocol. Each instrument is defined by three things:
ComponentDescriptionExample
ProtocolThe DeFi platformAave, Compound, Morpho
AssetThe token you depositUSDC, EURC, DAI
ChainThe blockchainBase, Ethereum
Examples:
  • Aave USDC on Base = 1 instrument
  • Compound USDC on Base = different instrument (same asset, different protocol)
  • Aave USDC on Ethereum = different instrument (same protocol & asset, different chain)
Each instrument gets a unique 32-byte identifier: 
0x00002105c053a3e1290845e12a3eea14926472ce7f15da324cdf0700056fc04b
This ID is all you need to query yields, compare options, or execute deposits - no need to understand the underlying protocol specifics.

​
The Problem

Today’s DeFi landscape is fragmented:
  • No Universal IDs: Each protocol uses different identifiers (Aave uses pool addresses, Compound uses market IDs)
  • No Cross-Chain Standard: Same asset on different chains has different representations
  • No Comparison Framework: Hard to compare USDC on Aave vs USDC on Compound
  • Integration Complexity: Each new protocol requires custom integration logic

Benefits of Universal IDs

Composability

Any protocol can integrate by supporting the instrument ID standard

Comparability

Compare yields across protocols using the same identifier format

Cross-Chain Ready

Chain ID embedded in ID enables future cross-chain routing

Developer Friendly

Simple 32-byte identifier works everywhere (contracts, APIs, databases)
