What It Is

Common is a “Private DeFi suite” positioned as a multi-chain privacy finance application. Its Web App is already live on mainnet. Users can connect an existing EVM wallet, deposit funds into a private shielder contract, and then withdraw to a new, unlinkable address, reducing the risk of having their public on-chain balances, transaction history, and wallet relationships traced. The mobile app is still on a waitlist.

Core Features

Common’s core focus is private asset management rather than acting as a traditional centralized exchange. It emphasizes a non-custodial design: “your keys, your crypto, your data,” meaning users remain in control of their assets and data. On the privacy side, it uses Zero-Knowledge technology to shield balances, transactions, and portfolio information, and also provides a TraceBreaker tool. The current documentation explicitly supports Aleph Zero EVM and Arbitrum, while Ethereum, Base, Avalanche, Polygon, BSC, Bera, and others are still listed as coming soon. In terms of assets, it mentions that USDT, USDC, and other stablecoins can gain privacy and yield capabilities, but it does not provide a complete asset list or trading-pair list.

Pricing and Fees

The website does not disclose clear platform fees, trading fees, yield-sharing terms, or specific rates. What can be confirmed is that it offers integrated gas fees: users can pay fees with the token they are shielding, without needing to prepare an additional gas token. This is beginner-friendly, but there is still no transparent fee schedule for assessing long-term costs.

Security, KYC, and Compliance

Common has been audited by Kudelski Security and zkSecurity, which is a meaningful plus for a privacy protocol. Its core features do not require KYC, but identity verification may be required if fiat on/off-ramp services are used. The operator is Cardinal Cryptography Sp. z o.o., based in Kraków, Poland, but the main text does not disclose any crypto business licenses, user fund insurance, or cold-wallet arrangements.

Pros, Cons, and Who It’s For

Its strengths are a clear privacy-focused experience, non-custodial design, support for connecting existing wallets, and coverage of stablecoin and yield use cases. Its drawbacks are limited chain support for now, the mobile app not being fully open, and insufficient fee and compliance information. It is better suited to users familiar with DeFi who care about on-chain privacy and want to break the link between wallet addresses. It is not ideal for users who need quick fiat trading, custodial customer support, or clear regulatory protections.

Access from China

The main text does not provide information on mainland China access, payments, or compliance, so china_access can only be rated as unknown. Users in China should independently verify network accessibility, wallet connectivity, fiat channels, and local regulatory requirements. If you only need general asset management, wallets such as MetaMask and Rabby may be alternatives; if privacy is the priority, you can compare it with solutions such as Railgun, Aztec, and Zcash.
