import { createDcaOrder, TimeUnit } from '@naviprotocol/astros-dca-sdk'

// SDK automatically handles coin selection, merging, and balance checks
const tx = await createDcaOrder(
  client,
  userAddress, // User's wallet address
  {
    fromCoinType: '0x2::sui::SUI',
    toCoinType: '0xa99b8952d4f7d947ea77fe0ecdcc9e5fc0bcab2841d6e2a5aa00c3044e5544b5::navx::NAVX',
    depositedAmount: '1500000000', // 1.5 SUI in atomic units (1.5 * 10^9)
    totalExecutions: 10,
    frequency: {
      value: 1,
      unit: TimeUnit.HOUR
    },
    priceRange: {
      minBuyPrice: 18000000, // Min cost in atomic fromCoin per 1 whole toCoin (best rate, e.g., 0.018 SUI)
      maxBuyPrice: 25000000  // Max cost in atomic fromCoin per 1 whole toCoin (worst rate, e.g., 0.025 SUI)
    }
  }
)

// Override for testing environment
const testTx = await createDcaOrder(
  client,
  userAddress,
  params,
  {
    dcaContract: '0xTEST_PACKAGE_ID',
    dcaGlobalConfig: '0xTEST_GLOBAL_CONFIG',
    dcaRegistry: '0xTEST_REGISTRY'
  }
)

Note: All amount fields must be in atomic units. For example:

1 SUI = 1000000000 (1 * 10^9)
1 USDC = 1000000 (1 * 10^6)

The SDK automatically:

✅ Fetches all coins of the specified type
✅ Merges multiple coins if needed
✅ Checks if balance is sufficient
✅ Handles SUI gas coin properly

2. Query User Orders

import { getUserDcaOrders } from '@naviprotocol/astros-dca-sdk'

// Get all active orders for a user
const result = await getUserDcaOrders('0xUSER_ADDRESS', {
  status: 'active', // 'active' | 'completed' | 'canceled'
  page: 0,
  pageSize: 10
})

console.log('Orders:', result.data)
console.log('Total:', result.pagination.total)

3. Get Order Details

import { getDcaOrderDetails } from '@naviprotocol/astros-dca-sdk'

const order = await getDcaOrderDetails('ORDER_ID')

console.log('Order status:', order.status)
console.log('From:', order.fromCoinSymbol, order.fromCoinLogoURI)
console.log('To:', order.toCoinSymbol, order.toCoinLogoURI)
console.log('Progress:', order.progress.percentage * 100, '%')
console.log('Executions:', order.fills.length)

// Show execution history
order.fills.forEach((fill, i) => {
  console.log(`Cycle ${fill.cycleNumber}:`, {
    amountIn: fill.amountIn,
    amountOut: fill.amountOut,
    price: fill.priceOutPerIn,
    status: fill.status,
    txDigest: fill.txDigest
  })
})

4. List All Orders by Status

import { listDcaOrders } from '@naviprotocol/astros-dca-sdk'

// Get orders grouped by status
const orders = await listDcaOrders()
console.log('Active:', orders.active.length)
console.log('Completed:', orders.completed.length)
console.log('Canceled:', orders.canceled.length)

// Or filter by specific status
const activeOrders = await listDcaOrders({ status: 'active' })

5. Cancel DCA Order

import { cancelDcaOrder, getUserDcaOrders } from '@naviprotocol/astros-dca-sdk'

// First, get the order with receiptId from backend API
const orders = await getUserDcaOrders(userAddress, { status: 'active' })

// Check if receiptId is available
const order = orders.data[0]
if (!order.receiptId) {
  throw new Error(
    'Receipt ID not available. Order may have been created before this feature was added.'
  )
}

// Use default production config
const tx = await cancelDcaOrder(
  {
    fromCoinType: order.fromCoinType,
    toCoinType: order.toCoinType
  },
  order.receiptId, // Receipt ID from backend API
  userAddress
)

// Override for testing environment
const testTx = await cancelDcaOrder(
  {
    fromCoinType: order.fromCoinType,
    toCoinType: order.toCoinType
  },
  order.receiptId,
  userAddress,
  {
    dcaContract: '0xTEST_PACKAGE_ID',
    dcaGlobalConfig: '0xTEST_GLOBAL_CONFIG',
    dcaRegistry: '0xTEST_REGISTRY'
  }
)

// Sign and execute
const result = await suiClient.signAndExecuteTransaction({
  transaction: tx,
  signer: keypair
})

Important Notes:

The receiptId is provided by the backend API in all order query responses
No additional blockchain queries are needed
If receiptId is null, the order was created before this feature was implemented

Configuration

DCA Options (Testing)

The SDK uses production contract addresses by default. You can override them for testing using the optional dcaOptions parameter:

import { DcaOptions } from '@naviprotocol/astros-aggregator-sdk'

// Test contract configuration
const testOptions: DcaOptions = {
  dcaContract: '0xTEST_PACKAGE_ID',
  dcaGlobalConfig: '0xTEST_GLOBAL_CONFIG',
  dcaRegistry: '0xTEST_REGISTRY'
}

// Apply to all DCA operations
const tx1 = await createDcaOrder(client, userAddress, params, testOptions)
const tx2 = await cancelDcaOrder(params, receiptId, address, testOptions)

Production vs Testing:

Environment	Configuration
Production	No `dcaOptions` parameter (default)
Testing	Pass `dcaOptions` with test contract

Available in:

✅ createDcaOrder()
✅ cancelDcaOrder()

Note: Query functions (getUserDcaOrders, getDcaOrderDetails, etc.) use the backend API, which is configured separately via updateConfig({ aggregatorBaseUrl }) in the Aggregator module.

Understanding Order ID vs Receipt ID

When you create a DCA order, two objects are created on-chain:

Order (stored in OrderRegistry)
- Contains all order data (amounts, schedule, status, etc.)
- Anyone can read the order status
- id field = Order ID (e.g., 0x2440d6...)
Receipt (owned by the user)
- Proof of ownership for the order
- Required to cancel the order
- receiptId field = Receipt Object ID (e.g., 0x6f528e...)
- Contains order_id field pointing to the Order

Why two IDs?

The Receipt is your ownership proof - only the Receipt holder can cancel the order
This follows Sui's object ownership model for security
The backend automatically extracts and stores both IDs for your convenience

Types

Order Response

All order queries return orders with the following structure:

{
  id: string                            // Order ID (on-chain order object)
  status: 'active' | 'completed' | 'canceled'
  orderNum: number
  user: string
  receiptId: string | null              // Receipt object ID (required for cancellation)
                                        // null for orders created before this feature

  // Coin information with metadata
  fromCoinType: string
  fromCoinSymbol: string      // e.g., "SUI"
  fromCoinLogoURI: string     // Token icon URL
  toCoinType: string
  toCoinSymbol: string        // e.g., "NAVX"
  toCoinLogoURI: string       // Token icon URL

  // Amounts
  depositedAmount: string
  originalAmountPerCycle: string
  minAmountOut: string
  maxAmountOut: string

  // Schedule
  gap: { value: number, unit: 'minute' | 'hour' | 'day' | 'week' | 'month' }
  cliff: { value: number, unit: 'minute' | 'hour' | 'day' | 'week' | 'month' }

  // Progress
  progress: {
    succeededInput: string
    depositedInput: string
    percentage: number        // 0.0 to 1.0
  }

  // Price ranges
  priceOutPerIn: { min: number | null, max: number | null }
  priceInPerOut: { min: number | null, max: number | null }

  // Timestamps
  createdAt: string
  updatedAt: string
  createTxDigest: string | null
  cancelTxDigest: string | null
}

Order Details

When calling getDcaOrderDetails(), you also get execution history and additional fields:

{
  ...orderFields,

  // Additional execution info
  currentCycle: number             // Current cycle number
  totalSucceeded: number           // Total successful executions
  lastExecutionStatus: string | null  // Status of last execution

  // Execution history
  fills: [
    {
      cycleNumber: number
      createdAt: string
      status: string
      amountIn: string
      amountOut: string
      protocolFeeCharged: string
      priceOutPerIn: number | null
      priceInPerOut: number | null
      txDigest: string | null
    }
  ]
}

Configuration

The SDK uses the default Astros aggregator API endpoint. If you need to customize it:

import { updateConfig } from '@naviprotocol/astros-aggregator-sdk'

// Optional: customize the aggregator endpoint
updateConfig({
  aggregatorBaseUrl: 'https://open-aggregator-api.naviprotocol.io/find_routes'
})

Note: DCA query functions automatically derive the API base URL from the aggregator configuration.
