0x0.ai vs Railgun: privacy design and usability (2026)

0x0.ai and Railgun take different approaches to on-chain privacy. 0x0.ai centers on Arcane, a wallet that manages stealth addresses and tracks transactions for users. Its planned Spectre DEX is meant to add private spot and leveraged trading, but the homepage marks those features as coming soon. Railgun is infrastructure rather than a standalone wallet or app: it uses zk-SNARK proofs to enable private transactions and interactions with smart contracts, and users access it through third-party apps.

That difference matters in practice. 0x0.ai presents a more direct product for stealth-address transfers, while Railgun depends on the wallets and front ends that integrate it. Railgun also covers more networks. Neither design should be treated as a guarantee of full anonymity, and Railgun’s privacy can depend on how users handle funds after shielding.

Railgun has the broader network footprint: it is deployed on Ethereum, Arbitrum, Polygon and BNB Chain. 0x0.ai is listed on Ethereum only. For users who want privacy tools on more than one of those networks, Railgun is the clearer fit. If you only need Ethereum and prefer a wallet specifically presented around stealth-address transfers, 0x0.ai may be more aligned with that use.

The reported TVL also differs substantially. 0x0.ai has about $254,000, compared with about $113.0 million for Railgun. TVL is a measure of funds held in a protocol, not a guarantee of safety or a measure of privacy quality. Still, the gap reflects a difference in scale: 0x0.ai is a small, early-stage product, while Railgun has a much larger amount of funds in its system. Neither figure removes smart-contract or user-side risks.

Fees are not published for either project. For 0x0.ai, the project does not state charges for Arcane, swaps or the planned Spectre DEX. Its claim that all revenue is redistributed to 0X0 holders suggests revenue-generating activity, but the fee types and amounts are not explained. Spectre is not yet presented as available, so its eventual costs cannot be assessed here.

Railgun also does not publish protocol fees, including any shielding or unshielding charges. The cost may depend on the third-party wallet or app used, as well as network gas on the selected chain. Before moving funds, check the relevant app’s transaction confirmation and current documentation for the total cost. Do not assume that the same charges apply across integrations or networks.

Both projects have two audits listed, but the audit details are not sufficiently transparent here to compare their scope or conclusions. 0x0.ai does not name the auditors or describe the scope. Railgun’s audit names, dates and findings are not public. An audit listing is not a guarantee that contracts are free of bugs; Railgun also faces risks in its zero-knowledge circuits, while 0x0.ai has wallet-software and smart-contract risks.

Privacy has limits in both cases. 0x0.ai does not explain in detail how stealth-address privacy can fail or what it does not conceal. Railgun’s own description notes that user behavior, such as how quickly funds are moved after shielding, can affect privacy. Privacy tools may also draw regulatory scrutiny, and neither project sets out a legal position for every jurisdiction. Check local rules before using either service, and remember that self-custody means lost access may not be recoverable.

Choose 0x0.ai if your priority is an available wallet built around stealth-address transfers, you use Ethereum, and you are comfortable with an early-stage project. Its links to documentation and a knowledge base may help users investigate the project, but its main trading product is still planned. The 0X0 token’s stated revenue redistribution is not described in enough detail to assess how it works.

Choose Railgun if you want zk-SNARK privacy for DeFi interactions and value support across Ethereum, Arbitrum, Polygon and BNB Chain. It has much higher TVL, but it is not a first-party app: the experience depends on a third-party integration. That makes integration choice part of the decision. For either project, confirm the available features, fees and local requirements in the specific app you intend to use before depositing or transacting.
