Code example

Limit order

import {
  hibitClient,
  HibitNetwork,
  OrderCategory,
  OrderSide,
  SubmitSpotOrderInput,
  DecimalOptions
} from '@delandlabs/hibit-sdk';

// Set client options (should be done once in your app)
hibitClient.setOptions({
  network: HibitNetwork.Testnet,
  hin: BigInt('123456'),
  proxyKey: 'your_proxy_private_key_hex'
});

async function submitLimitOrder() {
  const input: SubmitSpotOrderInput = {
    marketId: BigInt('10001'),
    orderCategory: OrderCategory.LimitOrder,
    limitOrderDetails: {
      orderSide: OrderSide.Bid, // Bid for buy, Ask for sell
      price: 100.5,
      volume: 0.01
    }
  };
  const decimalOptions: DecimalOptions = {
    baseAssetDecimals: 18,
    quoteAssetDecimals: 6
  };
  try {
    const txHash = await hibitClient.submitSpotOrder(input, decimalOptions);
    console.log('Limit order submitted, txHash:', txHash);
  } catch (err) {
    console.error('Submit limit order failed:', err);
  }
}
submitLimitOrder();

Swap order

import {
  hibitClient,
  HibitNetwork,
  OrderCategory,
  OrderSide,
  SwapV2ExactTokensType,
  SubmitSpotOrderInput,
  DecimalOptions
} from '@delandlabs/hibit-sdk';

// Set client options (should be done once in your app)
hibitClient.setOptions({
  network: HibitNetwork.Testnet,
  hin: BigInt('123456'),
  proxyKey: 'your_proxy_private_key_hex'
});

async function submitSwapOrder() {
  const input: SubmitSpotOrderInput = {
    marketId: BigInt('10001'),
    orderCategory: OrderCategory.SwapOrder,
    swapV2OrderDetails: {
      orderSide: OrderSide.Bid, // Bid for buy, Ask for sell
      exactTokensType: SwapV2ExactTokensType.Source, // Source: consume exactTokens, Target: get exactTokens
      exactTokens: '100'
      // minOut, maxIn can be added for slippage protection
    }
  };
  const decimalOptions: DecimalOptions = {
    baseAssetDecimals: 18,
    quoteAssetDecimals: 6
  };

  /*
    Parameter logic:
    - proxyPrivateKey: from reset-proxy-key
    - hin: Hibit Identity Number
    - marketId: Market identifier
    - orderSide: OrderSide.Bid (buy, use quote to buy base), OrderSide.Ask (sell, sell base for quote)
    - exactTokensType:
        SwapV2ExactTokensType.Source: consume exactTokens
        SwapV2ExactTokensType.Target: get exactTokens
    - exactTokens: string
        If Source: amount to consume
        If Target: amount to receive
    - minOut/maxIn: optional slippage protection
    - baseAssetDecimals/quoteAssetDecimals: decimals for each asset

    Token consumption logic:
    1. Source mode (exactTokensType=Source): consume exactTokens
       - If orderSide=Ask: consume base asset (ask)
       - If orderSide=Bid: consume quote asset (bid)
    2. Target mode (exactTokensType=Target): get exactTokens
       - If orderSide=Bid: consume quote to get base (bid)
       - If orderSide=Ask: consume base to get quote (ask)
  */

  try {
    const txHash = await hibitClient.submitSpotOrder(input, decimalOptions);
    console.log('Swap order submitted, txHash:', txHash);
  } catch (err) {
    console.error('Submit swap order failed:', err);
  }
}

submitSwapOrder();
