In this guide, we'll walk through creating a token on the Optimism blockchain in just 5 minutes using Bunzz—a step-by-step process anyone can follow.
1. Prerequisites and Setup
Before we begin, you'll need to prepare the following:
- Bunzz Console: For creating/deploying tokens without Solidity coding
- MetaMask Wallet: To interact with Optimism Network
- Optimism Documentation: Reference for Optimism Testnet (Op Sepolia)
- Learnweb3 Faucet: To obtain test ETH for transactions
👉 Get started with crypto token creation
Configuring MetaMask for Optimism Sepolia
- Open MetaMask and click the network dropdown
- Select "Add Network" at the bottom
- Enter these Optimism Sepolia testnet details:
| Parameter | Value |
|---|---|
| Network Name | OP Sepolia |
| RPC URL | https://sepolia.optimism.io |
| Chain ID | 11155420 |
| Currency Symbol | ETH |
| Block Explorer URL | https://sepolia-optimistic.etherscan.io |
- Click "Save" to add the network
2. Obtaining Test ETH from Faucet
Since we're using a testnet, you can acquire free ETH for transaction fees:
- Visit the Learnweb3 faucet
- Select "Optimism Sepolia" as your network
- Connect using GitHub authentication
- Paste your Optimism Sepolia address
- Click "Request" and confirm
Your wallet will now contain test ETH for deploying contracts.
3. Deploying Your ERC-20 Token
Follow these steps to create your token without writing any code:
Access Bunzz Platform:
- Visit Bunzz
- Login or register
Create New DApp:
- Connect your MetaMask wallet
- Click "Create DApp"
- Name your project (e.g., "OP Test Token")
Network Selection:
- Choose chain ID 11155420 (Optimism Sepolia)
Smart Contract Setup:
- Select "Token (ERC20)" template
Customize token details:
- Name: Your token name (e.g., "Op Test Token")
- Symbol: 3-4 letter identifier (e.g., "OTT")
Deployment:
- Click "Deploy"
- Confirm the transaction in MetaMask
Congratulations! Your Optimism token is now live.
4. Verifying Your Token
- Copy your token contract address
- Search on Optimism Sepolia Explorer
- Confirm the token details appear correctly

FAQ Section
Q1: Is coding knowledge required to create an Optimism token?
No! Platforms like Bunzz allow token creation through visual interfaces without Solidity programming.
Q2: How much does it cost to deploy a token?
On testnets, it's free using faucet ETH. Mainnet deployment requires real ETH for gas fees (typically $50-$200 depending on network congestion).
Q3: Can I upgrade my token after deployment?
Standard ERC-20 tokens are immutable. For upgradable tokens, you'd need advanced smart contract architecture using proxy patterns.
Q4: What's the difference between Optimism and Ethereum tokens?
Optimism tokens follow the same ERC standards as Ethereum but benefit from faster transactions and lower fees through Optimism's Layer 2 technology.
