ComethSwap Review 2026: Small 2021 Uniswap-Style DEX

ComethSwap is a decentralized exchange that was launched in 2021 and describes itself as a fork of Uniswap. Its official site is swap.cometh.io. Third-party write-ups say it lets users swap ERC-20 style tokens through liquidity pools, and one 2021 article mentions a liquidity pool between two tokens created on the platform.

Coverage of the project is limited. The homepage could not be retrieved for this review, and the descriptions available come from search snippets and third-party listing pages. Those sources report a small number of listed coins and trading pairs, and the figures vary from one page to another. One listing describes the platform as a centralized exchange based in France, which conflicts with most other descriptions.

The project does not publish, in the material reviewed, its team, audit history, fee schedule or detailed supported-chain documentation. Readers who want to use it should verify these details directly with the project before depositing funds.

ComethSwap is a decentralized exchange that works like other automated market makers. Instead of matching buyers and sellers in an order book, it holds pools of two tokens supplied by liquidity providers. The price of each token adjusts with the ratio of the pool.

When you swap, you trade against the pool rather than another person. The exchange quotes a price based on the pool balances, and larger trades move that price more. Liquidity providers earn a share of trading fees in return for depositing tokens, which also carries the risk of impermanent loss if prices diverge.

Public descriptions say the exchange runs on Ethereum sidechains, which are separate blockchains connected to Ethereum. This means transactions are settled on that network, and bridged assets carry the risks of the bridge involved. The project does not publish detailed technical documentation in the material reviewed.

The project does not publish a fee schedule in the material reviewed. In pool-based exchanges, a swap fee is typically built into the price, and network gas is paid separately. Check the quote in the interface before confirming a trade.

The material reviewed contains no published smart-contract audit reports, no custody model and no incident history, so security can't be assessed from public sources alone. A decentralized exchange does not hold user funds in a central account, but users remain exposed to smart-contract bugs, malicious token contracts and bridge risk if assets move between networks.

Regulatory status is not established in the material reviewed, and the conflicting descriptions of the project as centralized or decentralized make its operating model unclear. Check whether crypto trading is permitted where you live. Trading involves a real risk of losing money and is not suitable for funds you cannot afford to lose.

ComethSwap suits experienced DeFi users who already understand pool-based trading and want to swap a small set of listed tokens. It is less suitable for beginners or for anyone who needs documented security, fee transparency or broad token coverage before using it.
