Why people swap KCS to S.
Maximize trading discounts. KCS holders benefit from tier-based fee discounts on KuCoin. Swapping KCS to S allows users to access DeFi platforms built on Sonic for lower transaction costs and increased liquidity.
Participate in DeFi. Sonic is designed for high-speed DeFi applications, offering sub-second finality and 10,000+ transactions per second. By swapping KCS to S, users can participate in projects like SpookySwap and Beethoven X with minimal latency.
Support KuCoin ecosystem. KuCoin Spotlight token sales often involve KCS. Swapping KCS to S helps users stay involved in these sales without leaving the crypto ecosystem, ensuring they don’t miss out on potential opportunities.
Optimize gas costs. While KCS typically requires 3-second confirmations on the KCC network, swapping to Sonic’s mainnet can save users significant gas costs due to Sonic’s lower fees and faster confirmation times.

Questions people ask.
01 What's the current KCS to S exchange rate?
Right now 1 KCS equals about S. The rate updates every 60 seconds on this page. The exact amount you'll receive is locked at the moment your KCS arrives at the deposit address.
02 How long does a KCS to S swap take?
Average end-to-end time is about 5 minutes. The main variable is KCS network confirmation speed — typically 3 seconds. You can track progress in real time on the swap page.
03 Which KCS networks are supported?
SwapHub supports KCS on the KCC (KuCoin Community Chain) network. This is the primary network for KCS transactions and confirms in just 3 seconds.
04 What is the minimum and maximum amount?
Minimums vary by pair and are shown before you confirm — typically around $0.10–$1.00 equivalent. There's no hard maximum — larger orders may be split across providers automatically for the best rate.
05 Float rate vs Fixed rate — which should I pick?
Float gives you the best available rate at the moment your deposit arrives (usually a slightly better number, subject to movement). Fixed locks the rate when you create the order, costing about 0.4% extra — worth it for large amounts or when the market is moving fast.
06 Is there a fee on top of the exchange rate?
SwapHub charges no extra fee on top of the displayed rate — our margin is already included in what you see. You'll also pay the network fee for S and gas on your chosen KCS network.
07 What happens if I send the wrong amount?
If you send less than the minimum, the order pauses and you can add a top-up. If you send more than the estimate, you'll automatically receive the extra S at the locked rate. Sending a different coin to the KCS address is recoverable but requires contacting support.
08 Can I swap KCS to S inside Telegram?
Yes. @swapHUB_com_bot opens a Telegram Mini App with the same flow, same rates, same providers. Convenient for mobile users who already live in Telegram.
09 Is SwapHub regulated? Where is it based?
SwapHub operates as a non-custodial interface that routes orders across multiple licensed exchange providers. We don't custody funds, so the regulatory model is closer to an aggregator than an exchange. For jurisdiction-specific questions, see the Terms.
10 What networks does KCS support for swapping to S?
KCS supports swapping to S from both the KCC (KuCoin Community Chain) and Ethereum (ERC-20) networks.
