Gas Refund Program: Enjoy “Gasback” by Staking KNC

KyberSwap is excited to unveil our very first Gas Refund Program for KNC (Kyber Network Crystal) stakers! This aims to make trading on KyberSwap even more efficient and align incentives between KNC holders and KyberSwap users.

This idea has been brewing in our product pipeline for a few months and has already garnered strong community support in our governance forum and feature request page.

Starting from epoch 59 (18 July, ~2.07pm GMT+7), gas costs incurred by successful swaps on Ethereum would be partially refunded in the form of KNC based on your KNC staking tier, and users can claim refunds at the start of each new 2-epoch cycle (approximately every 4 weeks).

Moreover, KNC stakers are by default eligible to vote on KIPs (Kyber Improvement Proposals) and earn additional KNC voting rewards!

KyberSwap’s Gas Refund Program will launch only on Ethereum initially, but we have plans to expand to other popular chains such as Polygon, Arbitrum, and Optimism.


Ethereum continues to generate among the highest trading activity and volume in DeFi, and gas spent can also be seen as an important measure of trading activity on KyberSwap. However, gas costs can be relatively high at times. KyberSwap’s Gas Refund Program will play a big part in our ongoing efforts to help lower gas consumption for traders, especially for Ethereum traders.

It also provides another strong utility for KNC and rewards KNC holders who contribute to the growth of KyberSwap.

Eligibility Criteria

To claim gas refunds, users would first need to stake a minimum of 500 KNC and meet the necessary trading requirements.

KNC Staking Tier
  • Trading requirement: Value of each trade needs to be worth ≥$200; calculated at the point of the trade.

Other details

  • Each user has a maximum cap of $200 worth of gas refunds in each 2-epoch cycle (~4 weeks).

Step 4: After claiming your KNC, you can either stake it to increase your voting power (and rewards) for the next KIP, or add liquidity to KNC pools and earn fees.

Degen Tip: Vote on KyberDAO KIPs to earn more KNC

KNC stakers are by default eligible to vote on KIPs on our KyberDAO page: and earn KNC voting rewards. There will be new KIPs ever 2-4 epochs (4-8 weeks).
