Monitoring Orders

Once an order has been successfully created on-chain, its state can be monitored using several available methods, depending on the use case. For a full overview of order states and their transitions, refer to the Order States documentation.

Key Completion States

Orders progress through multiple internal states. However, from the perspective of the end-user experience, the following states indicate successful completion:

• Fulfilled

• SentUnlock

• ClaimedUnlock

Any of these states can be treated as successfully completed final state for application-level logic.

Quick Start

• Base URL:https://stats-api.dln.trade

• Full endpoint reference: Swagger and Redoc

• Examples: See the implementation examples in this GitHub repository.

Querying Orders

By Wallet Address

The POST /api/Orders/filteredList endpoint retrieves the current state and historical data for all orders associated with a wallet address. This endpoint is also used to populate the trade history view in deExplorer, which can serve as a reference implementation. Pagination is supported via skip and take parameters.

Example: Fetching Completed Orders for a Wallet

const URL = 'https://stats-api.dln.trade/api/Orders/filteredList';

const requestBody = {
  orderStates: ['Fulfilled', 'SentUnlock', 'ClaimedUnlock' ],
  externalCallStates: ['NoExtCall'],
  skip: 0,
  take: 10,
  maker: '0x441bc84aa07a71426f4d9a40bc40ac7183d124b9',
};

const data = await post(URL, requestBody);

Example: Filtering Completed Orders by Destination Chain (e.g. HyperEVM)

const requestBody = {
    giveChainIds: [],
    takeChainIds: [100000022], // HyperEVM Chain Id
    orderStates: ['Fulfilled', 'SentUnlock', 'ClaimedUnlock' ],
    externalCallStates: ['NoExtCall'],
    skip: 0,
    take: 10,
    maker: '0x441bc84aa07a71426f4d9a40bc40ac7183d124b9',
  };

By Transaction Hash

For inspecting a specific order, the GET /api/Orders/creationTxHash/{hash} endpoint returns full order details as shown on the deExplorer order page.

Example:

https://stats-api.dln.trade/api/Orders/creationTxHash/0x3fe11542154f53dcf3134eacb30ea5ca586c9e134c223e56bbe1893862469bc5

If multiple orders were created in a single transaction, this endpoint returns data only for the first order.

Multiple orders created in the same transaction

In cases where multiple orders are created in a single transaction, retrieve all order IDs using GET /api/Transaction/{hash}/orderIds .

For example, the transaction0x40ee524d5bb9c4ecd8e55d23c66c5465a3f137be7ae24df366c3fd06daf7de7e has been submitted to the BNB Chain. Calling the endpoint:

https://stats-api.dln.trade/api/Transaction/0x40ee524d5bb9c4ecd8e55d23c66c5465a3f137be7ae24df366c3fd06daf7de7e/orderIds

The response is an array, even if the transaction resulted in only one order:

{
    "orderIds": [
        "0x9ee6c3d0aa68a7504e619b02df7c71539d0ce10e27f593bf8604b62e51955a01"
    ]
}

An array instead of a single orderId is returned because a top-level transaction may perform several calls to DLN, thus leading to multiple orders being created.

Example:

export async function getOrderIdByTransactionHash(txHash: string) {
  const URL = `https://stats-api.dln.trade/api/Transaction/${txHash}/orderIds`;

  const response = await fetch(URL);
  
  if (!response.ok) {
    const errorText = await response.text();
    throw new Error(
      `Failed to get orderIds by transaction hash: ${response.statusText}. ${errorText}`,
    );
  }

  const data = await response.json();

  if (data.error) {
    throw new Error(`DeBridge API Error: ${data.error}`);
  }

  return data;
}

By orderId

The orderId is a deterministic identifier returned in the create-tx response or retrievable via the transaction hash.

An order state can be monitored directly by using GET /api/Orders/{orderId} .

Example:

https://stats-api.dln.trade/api/Orders/0x9ee6c3d0aa68a7504e619b02df7c71539d0ce10e27f593bf8604b62e51955a01

Response:

{
    "status": "ClaimedUnlock"
}

Example:

export async function getOrderStatusByOrderId(orderId: string) {
  const URL = `https://stats-api.dln.trade/api/Orders/${orderId}`

  const response = await fetch(URL);
  
  if (!response.ok) {
    const errorText = await response.text();
    throw new Error(
      `Failed to get order status by orderId: ${response.statusText}. ${errorText}`,
    );
  }

  const data = await response.json();

  if (data.error) {
    throw new Error(`DeBridge API Error: ${data.error}`);
  }

  return data;
}

Affiliate Fee Settlement

If set during order creation, the affiliate fee is automatically transferred to the affiliateFeeRecipient once the order reaches the ClaimedUnlock status.
