Trading on dYdX v4: Market Data, Orders, Accounts, and Transaction Queries
Summary
This guide describes how to connect to dYdX v4 and use its indexer and chain interfaces for market data, account and position queries, orders, transfers, and transaction lookups. It distinguishes the indexer, which serves REST and WebSocket data, from blockchain messages used to place orders, cancel them, and transfer assets. An order book example shows how to apply WebSocket updates to a local view of bids and asks.
The guide also discusses testnet setup, subaccounts, account mnemonics, and switching network configuration. Its examples illustrate querying transaction details using a cached transaction hash and a REST node. The main operational caveat is that indexer data may lag after an action, so an immediate query may not show a newly placed order. The article is an API usage walkthrough rather than a trading strategy or performance study; its account and network details may change as the platform evolves.
Key ideas
- dYdX v4 uses an indexer for market and account data and blockchain messages for trading actions.
- WebSocket order book updates can be applied to maintain a local view of bids and asks.
- Testnet and mainnet differ in configuration and some account behaviors.
- Indexer responses may lag after order placement, so immediate queries can miss an order.
- Transaction hashes can be used to retrieve blockchain transaction details through a REST node.
