Ekiden’s architecture provides speed, transparency, and resilience through a hybrid design that balances off-chain performance with on-chain trust. It operates across three key layers: Client, Infrastructure and Smart contract layer.

​
1. Client Layer

The Client Layer is the entry point for all user interactions. Users engage with the platform through:

  • Non-Custodial Aptos Wallet – Users maintain full control of their assets.
  • Ekiden CLOB dApp – Interface to submit orders and view the order book.
  • Ekiden API – Programmatic trading access for algorithmic strategies.
  • Submit Orders – Market and limit order support.
  • Deposit/Withdraw – Vault-based funds management.

​
2. Infrastructure Layer

Handles all off-chain operations for high-speed trading.

  • Preprocessing Engine – Validates and processes orders.
  • Matching Engine – Matches orders in real-time.
  • Liquidation Engine – Ensures solvency through liquidation.
  • Orderbook Root Hash – Anchored on-chain for transparency.
  • Inclusion Proofs – Merkle proofs provide auditability.

​
3. Smart Contract Layer

Runs on Aptos to ensure decentralized settlement and state integrity.

  • Orderbook Verifier – Validates trades using Merkle proofs.
  • Clearinghouse – Manages collateral and finalizes trades.
  • Position Registry – Tracks open positions, supports withdrawals.
  • Vaults – Modular and secure fund storage.
  • State Updates – Settlements and balances are updated on-chain.

​
Hybrid Design

Ekiden’s architecture combines:

  • Off-chain speed – Fast matching, low latency, and scalable infrastructure.
  • On-chain integrity – Transparent and trustless anchoring on Aptos.

This hybrid model delivers the performance of centralized exchanges with the security and control of DeFi platforms.
