## Initialize the Client

<CodeGroup dropdown>
  ```go main.go theme={null}
  package main

  import (
  	"context"
  	"fmt"
  	"log"
  	"math/big"
  	"time"
  	"github.com/ethereum/go-ethereum/common"
  	"github.com/ethereum/go-ethereum/common/hexutil"
  	"github.com/otimlabs/otim-go-sdk/client"
  	"github.com/otimlabs/otim-go-sdk/signer"
  )

  func main() {
  	ctx := context.Background()

  	// Initialize the signer with your private key
  	ethSigner, err := signer.NewEthSigner("<YOUR_OTIM_PRIVATE_KEY>")
  	if err != nil {
  		log.Fatal("Failed to create signer:", err)
  	}

  	// Create the client
  	otimClient, err := client.NewClient(
  		ethSigner,
  		"https://api.otim.com",
  		"<YOUR_OTIM_API_KEY>",
  	)
  	if err != nil {
  		log.Fatal("Failed to create client:", err)
  	}

  	fmt.Println("Otim client initialized successfully")
  }
  ```

  ```typescript index.ts theme={null}
  import { chains, createOtimServerClient, prepareSettlement } from '@otim/sdk-server';

  async function main() {
    const client = createOtimServerClient({
      appId: "<YOUR_OTIM_APP_ID>",
      privateKey: "<YOUR_OTIM_PRIVATE_KEY>",
      publicKey: "<YOUR_OTIM_PUBLIC_KEY>",
      apiKey: "<YOUR_OTIM_API_KEY>",
      environment: "production", // or "sandbox" for testnets
    });

    await client.init();
    console.log('Otim client initialized successfully');
  }

  main().catch(console.error);
