Quick start

import { createErpcClient } from '@elsoul/erpc-sdk'

const apiKey = process.env.ERPC_API_KEY
if (!apiKey) throw new Error('ERPC_API_KEY is required')

const erpc = createErpcClient({ apiKey })

const slot = await erpc.solana.rpc.getSlot().send()
const chainId = await erpc.ethereum.rpc.eth_chainId().send()

console.log({ slot, chainId })
erpc.close()

HTTP JSON-RPC methods return a pending request. Calling `.send()` performs the request, so request construction stays explicit and future middleware can be added without changing method signatures.
