Syncswap (Scroll) Crypto Exchange Review: Is It Worth Using in 2025?

SyncSwap on Scroll isn’t the flashy, high-volume DEX you might expect from a Layer 2 chain with serious backing. In fact, if you’re looking for a smooth, reliable way to trade tokens on Scroll, you might be better off with something else. As of November 2025, SyncSwap (Scroll) only supports 8 coins and 10 trading pairs. That’s less than half of what Skydrome, Scroll’s top DEX, offers. And while the idea of using SyncSwap - a platform known for its success on zkSync - sounds appealing, the reality on Scroll is messy.

What Is SyncSwap (Scroll)?

SyncSwap (Scroll) is a decentralized exchange built specifically for the Scroll network, an Ethereum Layer 2 using zkRollup technology. It’s not a new product - it’s a port of SyncSwap’s original platform, which first launched on zkSync Era in 2022. The team expanded to Scroll in 2023, hoping to ride the wave of zkRollup adoption. But unlike its zkSync version, which handles over $8 billion in total trading volume, SyncSwap (Scroll) is barely breaking the surface.

The platform works like most AMMs: you swap tokens directly from your wallet without a middleman. Transactions are fast, thanks to Scroll’s zkRollup tech, and gas fees are dirt cheap - around $0.02 to $0.05 per swap. That’s 98% cheaper than doing the same trade on Ethereum mainnet. For users tired of paying $2 in gas just to swap ETH for USDC, that’s a big win.

But here’s the catch: low fees don’t mean good experience. SyncSwap (Scroll) is functional, but it’s underdeveloped. There’s no official guide for Scroll users. No dedicated support channel. And the documentation? Almost all of it still points to zkSync.

Why SyncSwap (Scroll) Falls Short

The biggest problem? Liquidity. Or rather, the lack of it.

On Scroll, SyncSwap’s average liquidity pool size hovers between $150,000 and $300,000. Skydrome, by comparison, runs pools between $500,000 and $1.2 million. That gap shows up in your trades. If you’re swapping a lesser-known token, you’ll see 30-40% more slippage than on Skydrome. One user on Reddit reported trying to swap WETH for SCR - Scroll’s native token - and ended up losing 12% of their trade value just to slippage. That’s not normal. That’s a red flag.

Then there’s the token list. Only 8 coins? That’s not enough for a serious DeFi user. You won’t find major tokens like Aave, Compound, or even some Scroll-native stables. And SCR, the token you need to pay for gas on Scroll? It’s listed - but good luck buying it. Multiple users on the Scroll Governance Forum reported failed transactions when trying to purchase SCR on SyncSwap, even with gas limits set 2x higher than recommended. One user, DeFiNewbie42, said they tried three times in one day. All failed.

And no, it’s not just you. Between September and October 2025, at least seven users documented the same issue. The problem? The smart contract doesn’t properly handle SCR token approvals. It’s a bug. And as of mid-November 2025, it’s still not fixed.

Security and Trust

SyncSwap claims its contracts are audited by Scroll’s security team. That’s reassuring - but not enough. There’s no public audit report for the Scroll version. No link. No PDF. No GitHub commit. Just a vague statement. Meanwhile, Skydrome’s code is fully open, with multiple third-party audits published and reviewed by the community.

DeFi security expert Mikhail Ivanov put it bluntly in a November 2025 CoinDesk interview: “Multi-chain DEX deployments risk spreading security resources too thin.” He’s not wrong. SyncSwap’s team is juggling zkSync, Scroll, Linea, Taiko, and Sophon. That’s five networks. Each needs updates, monitoring, bug fixes, and support. When you spread yourself that thin, quality drops. And on Scroll, it already has.

Also worth noting: FxVerify shows zero user reviews for SyncSwap (Scroll) as of November 10, 2025. Zero. That’s not because it’s perfect. It’s because nobody’s using it.

Who Should Use SyncSwap (Scroll)?

There’s one group that might still benefit: early adopters betting on the SYNC token airdrop.

SyncSwap’s team has hinted that a native SYNC token is coming in late 2025. According to MEXC Blog’s October 2025 report, users who actively trade on any SyncSwap network - including Scroll - may qualify for a distribution. If you’re already holding tokens on Scroll and trading regularly, you could get rewarded. That’s the only real upside.

But here’s the trade-off: you’re trading on a platform with low liquidity, broken token purchases, and no support. Are you willing to risk $50 in failed transactions for a potential $500 airdrop? Maybe. But don’t expect reliability.

Another possible use case: cross-chain traders who already use SyncSwap on zkSync or Linea. If you’re moving between those chains and want to keep your trading habits consistent, SyncSwap (Scroll) offers a familiar interface. But even then, you’re better off using a bridge to swap on a more liquid DEX like Skydrome.

How to Use SyncSwap (Scroll) - If You Must

If you’re still set on trying it, here’s how to do it - and how to avoid the worst pitfalls.

1. Bridge your assets to Scroll. Use Scroll’s official bridge. Don’t use third-party bridges. The process takes 5-15 minutes, depending on Ethereum congestion.
2. Connect your wallet. MetaMask or Rabby work best. Make sure you’re on the Scroll network.
3. Go to syncswap.scroll.io. That’s the only official URL. Watch out for phishing sites.
4. Start small. Try swapping a small amount of ETH for USDC first. Don’t go all-in.
5. Don’t buy SCR here. Seriously. Use Skydrome or another DEX for SCR. SyncSwap’s SCR swap is broken.
6. Set gas limits manually. If a transaction fails, increase the gas limit to 150% of the recommended amount. Most failures are due to underbidding, not network issues.

And if you run into trouble? Don’t expect help. There’s no customer support. No live chat. No email. Your only option is to post on the Scroll Governance Forum or r/scrollnetwork - and hope someone replies.

SyncSwap (Scroll) vs. Skydrome: The Real Choice

Here’s the truth: SyncSwap (Scroll) isn’t the best DEX on Scroll. It’s not even close.

Skydrome is the clear winner. More tokens. More liquidity. Better reviews. Fewer broken transactions. And if you’re hoping for a SYNC airdrop? Skydrome users are also eligible. So why take the risk?

The Bigger Picture

SyncSwap’s move to Scroll was strategic. The team saw an opportunity to be first in a new ecosystem. But being first doesn’t mean being best. Scroll is growing fast - it captured 8% of all Layer 2 DEX volume in Q3 2025. But as Coin Bureau noted in November, “Top 3 DEXs now control 75%+ of volume across major L2s.”

SyncSwap (Scroll) isn’t in the top 3. It’s not even in the top 5. And with V3 launching on all networks in January 2026, the team will likely focus on zkSync and Linea - where the real volume is. Scroll might get left behind again.

For now, SyncSwap (Scroll) feels like a beta test. Not a product. If you’re curious, try it with $10. But don’t trust it with your savings. And don’t expect it to get better anytime soon.

Final Verdict

SyncSwap (Scroll) is not a reliable exchange. It’s a gamble with low liquidity, broken features, and no support. The only reason to use it is if you’re chasing a SYNC token airdrop and are willing to accept the risk.

For everyone else? Use Skydrome. It’s faster, safer, and actually works.
