CarbonSwap Review 2026: Green DEX on Energy Web Chain

CarbonSwap describes itself as a family of interconnected, sustainability-focused DeFi and NFT products. The first pieces were an automated market maker DEX and a bi-directional ERC-to-ERC bridge, called the Omnibridge, between Ethereum Mainnet and Energy Web Chain. A community post calls it the first zero-carbon DEX on the Energy Web blockchain.

Beyond swapping, the project has an NFT marketplace called GreenSea, with themed collections and merchandise tie-ins, and a token called SUSU used for farming and governance. It has been tracked since October 2021, and its public code lives on GitHub.

The scale is small. Total value locked is around 61,849 USD with a 1.7% rise over seven days, and no audits are listed. The homepage could not be checked for this review, so current activity should be confirmed directly on the site.

CarbonSwap is an automated market maker. Instead of matching buyers and sellers in an order book, it holds pools of two tokens. Traders swap against the pool, and the price moves according to the pool balance. Liquidity providers deposit both tokens and earn a share of trading fees, and they also take on impermanent loss.

Because it lives on Energy Web Chain, assets from Ethereum need to be moved over first. The Omnibridge locks or wraps an ERC token on Ethereum Mainnet and issues a wrapped version on Energy Web Chain. Once the transaction completes, the wrapped asset can be traded on CarbonSwap. The same path works in reverse.

The SUSU token ties into farming and a weighted, token-based governance model described by the project. The GreenSea marketplace extends the product family to NFTs.

CarbonSwap does not publish a fee schedule in the material reviewed. As an AMM, it would normally charge a small swap fee that goes to liquidity providers, and the rate is usually shown in the swap interface before you confirm a trade.

You should also expect network gas on Energy Web Chain and, when moving assets across the Omnibridge, transaction costs on Ethereum Mainnet. Check the quoted fee and price impact on screen before every swap or bridge transfer.

No audits are listed for CarbonSwap, and the material reviewed does not name a team or a bug bounty. AMM contracts and bridges are both common targets for exploits, and a bridge failure can leave wrapped tokens unbacked. Keep amounts small and approve only what you need.

CarbonSwap is non-custodial, so you hold your own keys, but that also means mistakes cannot be reversed. Its regulatory status is not published. Check that DeFi use is legal where you live.

CarbonSwap is for experienced DeFi users who are already active on Energy Web Chain or interested in sustainability-themed projects and accept the risk of a small, unaudited protocol. It is a poor fit for anyone who needs deep liquidity, large trades or audited, battle-tested contracts.
