What is Unichain?

Unichain is an EVM-compatible Ethereum layer-2 built by Uniswap Labs on the OP Stack, designed for fast, cheap swaps and DeFi — so MetaMask and ERC-20 tokens work unchanged at very low fees.

Unichain in plain English

Unichain is an Ethereum layer-2 built by the team behind Uniswap, on the same OP Stack as Optimism and Base. It runs standard Ethereum smart contracts with fast, sub-second blocks and low fees, so deploying an ERC-20 token works exactly like Ethereum — only far cheaper.

Gas in ETH

Gas on Unichain is paid in ETH, just like Ethereum and other OP Stack L2s. You need only a small amount of ETH on the Unichain network to transact and deploy a token. Fees are very low.

Why people choose Unichain

• Built for DeFi — designed by Uniswap Labs for fast, cheap swaps.
• Low fees — a fraction of Ethereum mainnet.
• EVM + MetaMask — same tools as Ethereum.
• OP Stack — part of the Optimism Superchain ecosystem.

Creating a token on Unichain

Because Unichain is EVM-equivalent, launching a token is the same simple ERC-20 process as Ethereum — only far cheaper. Our Unichain token creator deploys a verified contract in minutes with no coding, using MetaMask.

Is Unichain a good crypto to build on?

Unichain crypto has become a popular home for new tokens and projects, and it is worth understanding why. Unichain is built for fast, low-cost transactions, which makes it attractive for trading, DeFi and launching new tokens without high fees getting in the way. As an EVM-compatible network, Unichain runs the same ERC-20 token standard, wallets (like MetaMask) and developer tooling as Ethereum. That means anything you can build on Ethereum you can build on Unichain — including your own token — using familiar, battle-tested standards.

For anyone who wants to launch a token, this combination matters: Unichain gives you a real, liquid network with an active ecosystem of DeFi apps, DEXs and communities, while keeping the path to creating a token simple. In practice, Unichain crypto is used both by people trading and holding ETH and the tokens built on it, and by builders who choose Unichain as the launchpad for their own coin.

How to create your own Unichain token (no code)

You do not need to be a developer to launch a token on Unichain. Because most tokens are simply ERC-20 tokens deployed on the network, a no-code creator turns the whole process into a short form. Here is how it works:

1. Choose Unichain as your network in the Unichain token creator.
2. Set the details — your token's name, ticker symbol, total supply and decimals.
3. Plan the tokenomics — decide supply and allocation with the tokenomics generator.
4. Connect your wallet and deploy. You confirm one transaction and pay only the Unichain network fee in ETH. Your token is then live on Unichain with a verifiable contract address.

The process is non-custodial — you connect your own wallet and keep full ownership of the token and its entire supply. Nobody else can mint, freeze or take it. That makes launching your own Unichain crypto token genuinely accessible to anyone with an idea and a wallet.

Getting started with Unichain crypto

If you are new to Unichain, the practical first steps are straightforward. You need a wallet that supports Unichain, and a small amount of ETH to cover network fees. With those in place you can send and receive assets, use Unichain dApps and DEXs, and — when you are ready — create your own token. If you are still getting to grips with the fundamentals, start with what is cryptocurrency and crypto wallets explained, then come back to put it into practice.

The most empowering thing about Unichain is not just holding ETH or trading the tokens on it — it is that the same open network lets you create your own Unichain token in minutes. That is the step that turns you from a participant in Unichain crypto into a builder on it.
