Outgoing MultiTokens

Master Outgoing Multi-Token Transactions with OUTGOING_MULTITOKEN_TX Notifications

In the rapidly evolving world of blockchain, keeping track of multi-token transactions is essential for maintaining a secure and efficient platform. Tatum's OUTGOING_MULTITOKEN_TX notification type offers a powerful solution to help you stay informed about outgoing multi-token transactions (e.g., ERC-1155 transfers) from a specific address.

A MultiToken (ERC-1155) could be likened to a series of limited edition art prints, where each print belongs to the same series but has its unique edition number. In this scenario, ERC-1155 tokens can represent both the series (fungible aspect) and the individual editions (non-fungible aspect) within a single smart contract, allowing for seamless management and transfer of value.

How to do it?

import { TatumSDK, Ethereum, Network } from '@tatumio/tatum'

(async () => {
    const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM})
    
    const monitoredAddress = '0xF64E82131BE01618487Da5142fc9d289cbb60E9d'
    
    const subscription = await tatum.notification.subscribe.outgoingMultitokenTx({
        address: monitoredAddress,
        url: 'https://<YOUR_WEBHOOK_URL>' // replace with your handler URL
    })
    console.log(`Now you will be notified about all outgoing MultiToken transactions on ${monitoredAddress}`)
})()

This notification will be fired no matter what kind of MultiToken is being transferred.
