Examples 📚

Here are some quick examples to show you how easy it is to use Tatum SDK:

Perform RPC calls

{% tabs %} {% tab title="TypeScript" %} {% code overflow="wrap" lineNumbers="true" %}

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

(async () => {
    const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM})
    const latestBlock = await tatum.rpc.blockNumber()
    console.log(`Latest block is ${latestBlock.result}`)
    tatum.destroy();
})()

{% endcode %} {% endtab %}

{% tab title="JavaScript" %} {% code overflow="wrap" lineNumbers="true" %}

const { TatumSDK, Network } = require('@tatumio/tatum');

(async () => {
  const tatum = await TatumSDK.init({ network: Network.ETHEREUM });
  const latestBlock = await tatum.rpc.blockNumber();
  console.log(`Latest block is ${latestBlock.result}`)
  tatum.destroy();
})();

{% endcode %} {% endtab %} {% endtabs %}

Monitor activity on a blockchain address

{% tabs %} {% tab title="TypeScript" %} {% code overflow="wrap" lineNumbers="true" %}

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.incomingNativeTx({
        address: monitoredAddress,
        url: 'https://<YOUR_WEBHOOK_URL>' // replace with your handler URL
    })
    console.log(`Now you are subscribed for all incoming ETH transactions on ${monitoredAddress}`)
})()

{% endcode %} {% endtab %}

{% tab title="JavaScript" %} {% code overflow="wrap" lineNumbers="true" %}

const { TatumSDK, Ethereum, Network } = require('@tatumio/tatum');

(async () => {
    const tatum = await TatumSDK.init<Ethereum>({network: Network.ETHEREUM});
    const monitoredAddress = '0xF64E82131BE01618487Da5142fc9d289cbb60E9d';
    const subscription = await tatum.notification.subscribe.incomingNativeTx({
        address: monitoredAddress,
        url: 'https://<YOUR_WEBHOOK_URL>' // replace with your handler URL
    });
    console.log(`Now you are subscribed for all incoming ETH transactions on ${monitoredAddress}`);
})();

{% endcode %} {% endtab %}

{% tab title="curl" %} {% code overflow="wrap" lineNumbers="true" %}

curl -i -X POST \
  https://api.tatum.io/v4/subscription?type=mainnet \
  -H 'Content-Type: application/json' \
  -d '{
    "type": "INCOMING_NATIVE_TX",
    "attr": {
      "address": "0xF64E82131BE01618487Da5142fc9d289cbb60E9d",
      "chain": "ETH",
      "url": "https://<YOUR_WEBHOOK_URL>"
    }
  }'

{% endcode %} {% endtab %} {% endtabs %}
