Based on October 2023 liquidity data. Values may vary due to market conditions.
When you open KyberSwap Classic (BSC), you’re not greeted with dozens of tokens or a bustling order book. You see two trading pairs: USDT/WBNB and CGPT/BUSD. That’s it. If you’re used to Uniswap or PancakeSwap, this feels like walking into a tiny corner store when you expected a supermarket. But sometimes, small isn’t broken-it’s intentional. So is KyberSwap Classic (BSC) worth your time in 2025, or is it a relic left behind by its own ecosystem?
What Exactly Is KyberSwap Classic (BSC)?
KyberSwap Classic (BSC) is a decentralized exchange built on Binance Smart Chain. It’s not a new platform-it’s the original version of KyberSwap, launched back in 2018. Unlike its bigger siblings that now run on Ethereum, Polygon, and even Ronin, this version stays locked to BSC. It doesn’t support hundreds of tokens. It doesn’t have a fancy interface. It doesn’t even have a mobile app. But it does one thing differently: it uses a dynamic market maker model, meaning it doesn’t just rely on static pools like Uniswap. Instead, it adjusts prices in real time based on liquidity depth and market conditions.
This matters because it affects your slippage. For the USDT/WBNB pair, the spread is just 0.67%, and the depth at ±2% is $120. That’s tight. For comparison, a similar trade on PancakeSwap might have a 1.5% spread and less depth. If you’re trading small amounts of these two tokens, KyberSwap Classic (BSC) can give you cleaner fills.
Trading Pairs and Liquidity: Too Limited to Be Useful?
As of October 2023, KyberSwap Classic (BSC) supports exactly two coins: WBNB and USDT. The second pair is CGPT/BUSD. That’s it. No ETH, no SOL, no meme coins, no new DeFi tokens. If you’re trying to swap a token you just bought on Binance, you’re out of luck. This isn’t a platform for diversification. It’s a platform for precision.
The 24-hour trading volume? $626.30. That’s less than what some individual traders move on PancakeSwap in a single hour. The USDT/WBNB pair accounts for 77% of that volume. CGPT/BUSD? Barely $15. That’s not a liquidity issue-it’s a usage issue. Why would anyone use this when PancakeSwap offers hundreds of pairs with millions in volume? The answer: maybe no one should. But for the few who do, the depth is surprisingly stable. The $120 depth at ±2% means even if you trade $100, you’re unlikely to move the price. That’s rare on DEXs with low volume.
Fees: Zero? Maybe. But It’s Complicated
KyberSwap Classic (BSC) doesn’t charge maker or taker fees on its Optimism version. But what about BSC? The sources don’t say. That’s a red flag. Most DEXs on BSC charge 0.25% per trade. If KyberSwap Classic (BSC) truly has no fees, that’s a big win. But if it’s just not reporting them, you could be paying hidden costs through slippage or gas.
Gas fees on BSC are low-usually under $0.10 per swap. So even if there’s a 0.25% fee, you’re still paying less than a dollar. But if you’re swapping $50, that’s 0.25% = $0.125. That’s not nothing. And if you’re using this because you think it’s fee-free, you could be misled. No official documentation confirms the fee structure for this specific version. That’s a problem for transparency.
How to Use KyberSwap Classic (BSC)
Using it is straightforward, but only if you know what you’re doing. You need a Web3 wallet connected to Binance Smart Chain: MetaMask, Trust Wallet, or Rabby. Once connected, go to the website, click “Swap,” pick your token, enter the amount, and confirm. That’s it. No KYC. No sign-up. No email. Just blockchain.
But here’s the catch: you won’t find guides for this version. Most tutorials, YouTube videos, and blog posts focus on KyberSwap v3 or the multi-chain version. The Classic (BSC) interface hasn’t changed in years. If you’re new to DeFi, you’ll figure it out in 15 minutes-but you’ll also wonder why you’re using this instead of PancakeSwap, which does the same thing with 500 more tokens and 100x the volume.
Security and Regulation: No Oversight, But No Hacks Either
KyberSwap Classic (BSC) is non-custodial. That means you hold your keys. No one can freeze your funds. No one can ban you. That’s good. But it also means there’s no customer support. If you send funds to the wrong address? Gone. If the contract has a bug? You’re on your own.
There’s no regulatory oversight. No license. No audits published for the Classic (BSC) version. The broader KyberSwap ecosystem has been audited by reputable firms like CertiK and OpenZeppelin, but those audits cover newer versions. The Classic (BSC) smart contracts haven’t been publicly reviewed in years. That’s risky. You’re trusting code that hasn’t been updated since 2022. In DeFi, that’s ancient history.
Why Does This Even Exist?
KyberSwap’s main platform hit $3.7 billion in trading volume in March 2025. It’s integrated with 17 new projects. It launched a Ronin version. It added a “Suggested Slippage” feature. It has over 290,000 traders. So why does KyberSwap Classic (BSC) still exist?
The answer: it’s a legacy product. It’s not dead, but it’s not growing. It’s a holdover from the early days of DeFi when BSC was the only scalable chain. Now, most users have moved on. The traffic numbers tell the story: 174,000 monthly visits to the whole KyberSwap network-but almost none of those are trading on Classic (BSC). The bounce rate is 31%, and users stay 4 minutes. That’s not people swapping. That’s people researching.
There’s no evidence of active development for this version. No GitHub commits in 2025. No announcements. No new token listings. If you’re looking for innovation, you won’t find it here.
Who Should Use KyberSwap Classic (BSC)?
Only two types of people should consider it:
- You’re trading USDT and WBNB regularly and want the tightest possible spread on BSC.
- You’re running a bot or script that needs a simple, stable DEX endpoint for these two pairs and don’t care about anything else.
If you’re a casual trader, a beginner, or someone looking to swap anything beyond those two tokens? Skip it. Use PancakeSwap. It’s faster, cheaper, and has more options. Even if you’re on BSC, PancakeSwap’s volume means better prices, deeper liquidity, and more reliable execution.
The Verdict: A Niche Tool, Not a Mainstream Choice
KyberSwap Classic (BSC) isn’t broken. It works. The math checks out. The slippage is low. The interface is clean. But it’s stuck in 2021. While the rest of DeFi exploded with cross-chain bridges, multi-chain aggregators, and AI-driven liquidity routing, this version stayed put. It’s like owning a flip phone in 2025-functional, but you’re missing everything.
If you’re an advanced user who needs a simple, low-slippage swap for WBNB and USDT, and you’ve tested it against other options, then yes-keep using it. But if you’re wondering whether to start here? Don’t. You’re better off with PancakeSwap, or even the newer KyberSwap v3 on Ethereum or Polygon.
The future of KyberSwap isn’t here. It’s on Ronin. It’s in the API integrations. It’s in the affiliate program. KyberSwap Classic (BSC) is just a footnote now.
Alternatives to KyberSwap Classic (BSC)
If you’re on Binance Smart Chain and want more than two tokens, here are your real options:
- PancakeSwap: The dominant DEX on BSC. 63% market share. 1,000+ tokens. $1.2B+ daily volume. Low fees. Easy to use.
- QuickSwap: Built on Polygon but supports BSC via bridges. Good for cross-chain traders.
- 1inch: Aggregates multiple DEXs. Finds the best price across chains. Great for complex swaps.
- KyberSwap v3: The updated version. Multi-chain. Higher volume. Better UI. Still no KYC.
None of these are perfect. But they’re alive. KyberSwap Classic (BSC) isn’t.
Final Thoughts
KyberSwap Classic (BSC) is a ghost of what DeFi once was. It’s not evil. It’s not scammy. It just doesn’t belong anymore. The technology behind it-dynamic market making-was ahead of its time. But the implementation? Frozen. If you’re here because you heard it was “the first dynamic market maker,” you’re right. But that was 2018. In 2025, being first doesn’t matter. Being useful does.
Use it if you have a very specific need. Otherwise, move on. Your time and your funds deserve better.

December 4, 2025 AT 16:41Actually, this is one of the few DEXs where you can get near-zero slippage on WBNB/USDT if you're trading under $500. I've tested it against PancakeSwap and KyberClassic wins on price impact every time for small swaps. No fluff, just clean execution.

December 5, 2025 AT 23:01Stop pretending this is a viable option. $626 in 24-hour volume? That's not a DEX, that's a graveyard. PancakeSwap has 1000x the liquidity and 10x the tokens. If you're still using this, you're either a bot or you're lost in 2019.
