How do I keep track of payments to multiple address

Question

To track the payments we can use streaming API is good solution. already answered.

In my case I have a master account(M) as well sub-master(SM) account, I need to have multiple sub-master(SM) accounts.

the process is like when a user trusts MyAsset and buy MyTokens on DEX and now and in return gets MyTokens.

With these tokens, the user will now trade with sub-master(SM) accounts

so I need to track the payment of MyAsset on sub-master account

as I have multiple sub-master accounts possibly 15-20

I need to track received transaction on each and every sub-master(SM) account.

Note: Master account does not have Secret Keys of Sub-Master account.

As a master account owner ,now I need to perform some operations when the user sends mytoken to sub-master account.

is it possible to achieve in a single job without watching separately all the sub-master accounts?

Answer 1

Check StellarNotifier, a standalone service that tracks all operations for the unlimited number of accounts using a single Horizon stream. I made it as flexible as possible to simplify standard pub-sub tasks of tracking multiple update streams for anchors and payments processors.

You can dynamically create subscriptions with guaranteed delivery to track specific accounts, assets, operations types.

Answer 2

not very optimized answer but this will watch payment on both the accounts.

app.get("stream", function (req, res) {
    let funding_account1 = issuer.publicKey // This needs to be a valid account on the network and should return an Account object
    let stream = server.payments()
        .forAccount(funding_account1)
        .cursor('now')
        .stream({
            onmessage: function (message) {
                if ((message.type == "create_account") || (message.type == "payment")) {
                    var details = "from:" + message.from + ",to:" + message.to + ",amount:" + message.amount;
                    console.log(details)
                    // Set your own code after we find our create account event
                    stream()
                }
            }
        })
    let stream2 = server.payments()
        .forAccount(funding_account2.publicKey)
        .cursor('now')
        .stream({
            onmessage: function (message) {
                if ((message.type == "create_account") || (message.type == "payment")) {

                    var details = "from:" + message.from + ",to:" + message.to + ",amount:" + message.amount;
                    console.log(details)
                    // Set your own code after we find our create account event
                    stream()
               }
            }
        })
})
