(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" %}
