# Building on Orderly

> Start building your dApp on Orderly's omnichain trading infrastructure.

Orderly gives builders the trading infrastructure, liquidity access, and integration tooling needed to launch their own derivatives application without building the full stack from scratch.

Builders can create a perp DEX on top of Orderly's shared-liquidity orderbook, while users interact from supported chains without switching to a separate trading chain in the product experience.

## What builders get

* **Shared liquidity:** Access the same liquidity layer used across the Orderly ecosystem.
* **Orderbook infrastructure:** Build on top of Orderly's matching and order management services instead of operating your own engine.
* **Omnichain user flows:** Support registration, deposits, withdrawals, and trading from supported chains.
* **Flexible integration paths:** Choose between SDKs, UI components, Python tooling, or direct API access.
* **Self-custody model:** Users keep control of their wallets while interacting with your application.

## High-level architecture

Orderly's omnichain system is organized into three layers:

1. **Asset Layer:** Lives on each supported chain and handles user-facing actions such as account registration, deposits, and withdrawals.
2. **Settlement Layer:** Lives on a single chain and acts as the transaction ledger behind the scenes.
3. **Engine Layer:** Runs the orderbook and related trading services used for order management and execution.

## Start here

Use these pages as your builder onboarding path:

* **Plan the integration:** Start with the [Integration Checklist](/build-on-omnichain/integration-checklist) for the overall build and launch sequence.
* **Understand the system:** Review the [Smart Contract Overview](/build-on-omnichain/overview) and [Smart Contract Addresses](/build-on-omnichain/addresses).
* **Implement core user flows:** Follow [Accounts](/build-on-omnichain/user-flows/accounts), [Wallet Authentication](/build-on-omnichain/user-flows/wallet-authentication), [Withdrawal & Deposit](/build-on-omnichain/user-flows/withdrawal-deposit), and [Order Management](/build-on-omnichain/user-flows/order-management).
* **Cover trading operations:** Add [Settle PnL](/build-on-omnichain/user-flows/settle-pnl), [Custom Fees](/build-on-omnichain/user-flows/custom-fees), and real-time integrations from the [WebSocket API docs](/build-on-omnichain/websocket-api/introduction).
* **Integrate against the APIs:** Use the [API introduction](/build-on-omnichain/introduction) and [API authentication guide](/build-on-omnichain/api-authentication).
* **Handle onboarding questions:** Use [Integration FAQs](/build-on-omnichain/integration-faqs) and [Partner Support](/build-on-omnichain/partner-support) for builder-facing support guidance.
