Common or Hinkal: Which Privacy Tool Should You Use in 2026?

Common is built around a focused flow: connect an existing wallet, deposit supported assets into a privacy shielder, then withdraw to a different address. It uses zero-knowledge technology to make the public link between those addresses harder to follow. Common supports Arbitrum and Aleph Zero EVM, and says its core features do not require KYC.

Hinkal covers more use cases. Its consumer app is designed for private transfers, swaps and bridging; it also offers a browser-extension wallet, a workspace for treasury teams, and developer tools. Hinkal lists 11 networks, though supported actions vary by product and chain. It says it does not run KYC.

Neither product makes activity disappear from the blockchain or guarantees anonymity. Your choice is mainly between Common’s narrower shield-and-withdraw flow and Hinkal’s broader set of privacy features.

Neither publishes a clear fee schedule, so you should compare the transaction quote before approving anything. Common says it integrates gas fees so you can pay in the asset being shielded. That may avoid needing to acquire a separate network token for gas, but it does not tell you the full cost of a deposit, withdrawal or any yield option. Check whether the quote covers the whole flow.

Hinkal’s costs can depend on the network and action. You may need to account for network gas, and a swap or cross-chain route can add costs such as a spread or bridge charge. Review the amount expected to arrive at the destination, not just the amount leaving your wallet.

For either app, pause if the final quote is unclear. A transaction’s network fee can change with network conditions, and a later withdrawal may have a separate cost.

Both describe their products as non-custodial, which is different from handing funds to a conventional exchange. But self-custody does not eliminate smart-contract vulnerabilities, wallet approval risks or failures in integrated services. Privacy tools also cannot guarantee that activity will resist every form of analysis; timing, amounts and information shared elsewhere can matter.

Common names Kudelski Security and zkSecurity as auditors, but detailed reports and their scope are not published. Hinkal lists two audits, but their names, dates, reports and covered contract versions are not published. An audit count or auditor name alone cannot establish that the current contracts are risk-free.

Before depositing, check the contract and asset details in the app, read each approval carefully, and start with an amount you can afford to lose. Consider whether the privacy benefits justify the contract and operational risks for your intended use.

Common’s core flow is relatively direct if you already use a compatible wallet: connect it, shield supported funds, and withdraw to a new address. Its current networks are Arbitrum and Aleph Zero EVM. The mobile app is described as waitlist-only, so do not assume a generally available phone app. Confirm that your asset and network are supported before sending funds.

Hinkal gives you more entry points, but that can make the choice less simple. You can use its app with wallets you already have or consider its separate browser-extension wallet. Prime is aimed at treasury teams, while the API and SDK are for developers. The relevant network and available actions depend on which product you choose.

If you want one clear privacy flow, Common may be easier to assess. If you need swaps, DeFi or team features, Hinkal offers more options, but check the setup and supported route for your exact task.

Pick Common when your priority is shielding funds and separating a deposit address from a withdrawal address on Arbitrum or Aleph Zero EVM. It is the more focused choice, though fees, withdrawal limits and detailed audit reports are not published. Its advertised mobile access is not generally available yet.

Pick Hinkal when you want to explore private transfers, swaps or DeFi across a broader list of networks, or need a workspace for a team or tools for a product. Its wider feature set does not mean every action works on every chain, and its costs and audit details still need checking.

Before using either, confirm the asset, network and destination in the app, review the full transaction quote and understand the limits of on-chain privacy. Neither should be treated as a guarantee of anonymity.
