Uniswap v2 on Soneium Crypto Exchange Review: What You Need to Know in 2025

Uniswap v2 on Soneium isn’t just another decentralized exchange. It’s the first time a major entertainment giant - Sony - has opened its digital doors to open finance. Launched in May 2025, this integration brings Uniswap’s proven trading engine to Soneium, a Layer 2 blockchain built by Sony Block Solutions Labs and Startale Group. If you’ve used Uniswap on Ethereum before, the interface feels familiar. But the underlying tech? That’s where things get interesting.

What Is Soneium, and Why Does It Matter?

Soneium isn’t another Ethereum sidechain. It’s an Optimistic Rollup built on the OP Stack, the same technology behind Optimism and other Superchain networks. That means it inherits Ethereum’s security while slashing transaction costs. Unlike older Layer 2s that still struggle with gas spikes, Soneium keeps fees low and predictable - critical for everyday users trading NFTs, music rights, or game assets.

The real difference? Soneium is designed for entertainment. It’s not just a blockchain for DeFi traders. It’s built for fans of Sony’s movies, music, anime, and video games. Think of it as a backstage pass to tokenized IP. If you own a digital collectible from a PlayStation game or a song licensed from a Sony artist, Soneium lets you trade it without leaving the ecosystem.

How Uniswap v2 Works on Soneium

Uniswap v2 on Soneium runs the exact same code as the version on Ethereum. No magic. No surprises. That means:

• You swap tokens using liquidity pools
• Fees are still 0.01%, 0.05%, 0.3%, or 1% depending on the pair
• You provide liquidity by depositing two tokens in equal value
• You earn trading fees proportional to your share of the pool

The only change? The network you’re on. Instead of paying $5 to swap USDC for ETH, you might pay $0.03. That’s not theoretical - it’s what users on Soneium experience daily. And since Soneium uses Optimistic Rollups, your trades are still settled on Ethereum. Your assets are just as safe as if you were on mainnet.

Why Choose Uniswap v2 Over v3 on Soneium?

Uniswap v3 is more powerful - it lets you set custom price ranges and concentrate your liquidity. But on Soneium, v2 is the default. Why? Simplicity.

For most users, especially those new to crypto, v2 is easier. You don’t need to guess price ranges or manage multiple positions. Just pick your tokens, hit swap, and go. The interface doesn’t overwhelm you with options. That’s intentional. Sony isn’t trying to attract crypto degens. They’re trying to bring in fans who’ve never used a wallet before.

If you’re an advanced trader, you might miss v3’s efficiency. But for now, the trade-off makes sense. Soneium’s goal is adoption, not arbitrage.

Token Support and Liquidity

Soneium’s initial token list is narrow but focused. You won’t find 500 obscure memecoins here. Instead, you’ll see:

• USDC - for stable trading
• ETH - the base asset
• SONE - Soneium’s native token
• Tokenized Sony IP - like NFTs from PlayStation, Crunchyroll, or Sony Music

There are fewer pairs than on Uniswap on Polygon or Arbitrum. That’s normal for a new chain. Liquidity is still building. But here’s the kicker: Sony has over 1 billion active entertainment users globally. If even 1% of them start using Soneium, liquidity will explode.

Right now, the biggest liquidity pools are USDC/ETH and SONE/ETH. If you’re adding liquidity, stick to these. Avoid exotic pairs until volume grows.

Wallet Compatibility and Setup

You don’t need a new wallet. MetaMask, Coinbase Wallet, and Rabby all work. Just add the Soneium network manually:

1. Open your wallet and go to Network Settings
2. Click “Add Network”
3. Enter Soneium’s RPC URL, chain ID, and symbol (available on soneium.org)
4. Confirm and switch networks

Once connected, your wallet shows your Soneium balance. Swap tokens like you would on Ethereum. The UI is identical. The experience? Faster and cheaper.

Pros and Cons of Uniswap v2 on Soneium

Pros

• Low fees - Swaps cost pennies, not dollars
• Entertainment focus - Access to Sony’s IP, NFTs, and media assets
• Ethereum security - No compromise on safety
• Easy for beginners - No complex settings, clean interface
• Massive user potential - Sony’s audience is 100x larger than most DeFi projects

Cons

• Low liquidity - Fewer trading pairs than on Arbitrum or Polygon
• Centralized sequencing - Transactions are ordered by a single entity (Sony), which reduces decentralization temporarily
• No concentrated liquidity - v3 features aren’t available yet
• New ecosystem - No proven track record beyond May 2025

How It Compares to Other DEXs

Here’s how Uniswap v2 on Soneium stacks up against other Layer 2 DEXs as of May 2025:

Comparison of Uniswap v2 on Soneium vs Other Layer 2 DEXs

Feature	Soneium	Arbitrum	Optimism	Polygon
Transaction Cost	~$0.01-$0.05	~$0.05-$0.20	~$0.05-$0.20	~$0.02-$0.10
Uniswap Version	v2 (v3 available)	v3	v3	v2/v3
Token Pairs	15-20 (entertainment-focused)	300+	250+	82+
Primary Audience	Entertainment fans	DeFi traders	DeFi traders	General crypto users
Decentralization	Medium (centralized sequencer)	High	High	High
Integration with Real-World Brands	Sony (IP, games, music)	None	None	None

Soneium doesn’t win on liquidity or decentralization. It wins on potential. No other DEX has a direct pipeline to millions of people who already spend money on Sony content.

Who Should Use It?

If you’re a Sony fan - who owns a digital collectible from a PlayStation game, bought a NFT from Crunchyroll, or holds a music token from a Sony artist - this is your exchange. You’re not just trading crypto. You’re engaging with your favorite entertainment.

If you’re a crypto beginner - you’ll appreciate the simplicity. No confusing fee tiers. No need to understand impermanent loss right away. Just swap, bridge, and explore.

If you’re a liquidity provider - you’re taking a risk. But you’re also getting in early. If Soneium grows, your position could be worth more than on a saturated chain.

If you’re an advanced trader - wait for v3. Until then, you’ll miss out on concentrated liquidity. Stick to Arbitrum or Optimism for now.

What’s Next for Soneium and Uniswap?

The roadmap is clear. By late 2025, expect:

• More Sony IP tokenized - think movie soundtracks, anime episodes, and game skins
• Uniswap v3 coming to Soneium - for deeper liquidity control
• Integration with Sony’s apps - swap tokens directly in PlayStation or Crunchyroll
• Cross-chain bridges to other Superchain networks - like Base or OP Mainnet

This isn’t a side project. Sony is investing billions. Startale Group, their blockchain partner, has deep DeFi experience. Uniswap Labs didn’t just deploy code - they handed over governance to a DAO. This is a long-term play.

Final Verdict

Uniswap v2 on Soneium isn’t the most powerful DEX. But it might be the most important one launched in 2025. It’s not trying to beat Arbitrum on volume. It’s trying to bring crypto to people who’ve never heard of a wallet.

The fees are low. The interface is clean. The connection to Sony’s ecosystem is real. And if even 1% of Sony’s billion+ users start trading on Soneium, DeFi will have crossed a new threshold.

Right now, it’s early. Liquidity is thin. The ecosystem is small. But the potential? Massive. If you’re interested in where crypto meets mainstream entertainment - this is the place to watch.
