OrderBook Agent

OrderBook Agent runs user-set buy and sell orders and supports order matching. This use case includes the following operations:

1. Create an OrderBook Agent.

2. Deposit tokens into the Agent, and the user creates a limit order.

3. Place a limit order and obtain the NoteID of the order.

4. Use the Agent from the Basic use case to take the order and complete the order matching and transaction.

Create

Execute the following command to create two OrderBook Agents:

node ./orderbook/create.js

Example output:

wBn7-31aDtChhLfUk_eXNG9Nbafa_ghT29XRxk7osiM create orderbook agent: <YourOrderBookAgent1>  
ORHaLUrAiknTAq2Wszoyl6buJrd3MqDKLTF_2CggLtw create orderbook agent: <YourOrderBookAgent2>

Configure ORDERBOOKAGENT1 and ORDERBOOKAGENT2 in the .env.local file and load:

export $(cat .env.local | xargs)

Deposit Token into Agent

node ./orderbook/deposit.js --walletN=2 --agentId=$ORDERBOOKAGENT2

Check balance:

node ./balance.js --address=$ORDERBOOKAGENT2

Create a limit order

Use the following command to create a limit order:

node ./orderbook/make.js --walletN=2 --agentId=$ORDERBOOKAGENT2

Example output:

openOrders {  
  MVBggDjYkl3UxoHRZ2rO6ZLDcN4ax4Af6rehyYJ3CH0: {  
    ID: 2600,  
    AssetID: 'AttsQGi4xgSOTeHM6CNgEVxlrdZi4Y86LQCF__p4HUM',  
    HolderAssetID: '0fLIp-xxRnQ8Nk-ruq8SBY8icaIvZMujnqCGU79fnM0',  
    NoteID: 'MVBggDjYkl3UxoHRZ2rO6ZLDcN4ax4Af6rehyYJ3CH0',  
    IssueDate: 1733297306962,  
    HolderAmount: '3',  
    Amount: '1',  
    Status: 'Open',  
    Price: 3,  
    Issuer: 'RPFQd69SX2tbrtNBfVxzVSt9zQYk07WrHOCDhxDHu0o'  
  }  
}

Query the order:

node ./orderbook/query.js --agentId=$ORDERBOOKAGENT2

Set the NoteID as an environment variable:

export NOTEID=<NoteID>

Take order

Use Basic Agent1 to take the order:

node ./basic/take.js --walletN=1 --agentId=$AGENT1 --noteId=$NOTEID

After the transaction is completed, check the balance of both Agents:

node ./balance.js --address=$AGENT1
node ./balance.js --address=$ORDERBOOKAGENT2
