    • ▫️Industry: Decentralized Finance / Derivatives Trading
    • ▫️Engagement Duration: 9 months.
    •  

Objectives

    • ▫️To build a cross-chain perpetuals trading platform that:
      ▫️Enables margining and settlement across multiple L1 and L2 ecosystems
      ▫️Offers real-time trading of perpetual futures with unified liquidity
      ▫️Ensures secure interoperability using messaging bridges and zk-based proofs
      ▫️Provides plug-and-play composability with other DeFi protocols

Solution Architecture

    • TechSteck Solutions developed a modular derivatives protocol leveraging:

      ▫️Solidity smart contracts for core trading logic
      ▫️LayerZero + Wormhole for secure cross-chain messaging and liquidity sync
      ▫️zkSNARKs for off-chain position proofs validated on settlement layers

      Key Components:

    • ▫️Multi-Chain Settlement Layer: Trades can be opened on one chain and closed on another, with margin adjustments reflected across all chains via LayerZero.
      ▫️Unified Liquidity Engine: Designed shared pools with vaults on multiple chains, synced through Wormhole Guardian set and verified oracles.
      ▫️ZK Position Verification: Generated zk proofs of trade history and margin state, enabling users to transfer positions across L2s without re-verification.
      ▫️Composable Trading SDK: Created DeFi SDK for aggregators, vaults, and DEXes to integrate perpetual trading natively.
