chain_get_era_by

How to use it

// yarn add @tatumio/tatum

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

const tatum = await TatumSDK.init<Casper>({ network: Network.CASPER })

const blockHash = 'a4b607420ae737f9cd474af73c9f5e908f61edd2e57d48371d15835127b46aaf' // Replace with actual block hash
const blockHeight = 3229836 // Replace with actual block height

const resultByHash = await tatum.rpc.chainGetEraByBlock({ hash: blockHash })
const resultByHeight = await tatum.rpc.chainGetEraByBlock({ height: blockHeight })

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs
