Using Stealth Addresses to Improve Privacy in No-KYC Trading
In the no-KYC DeFi trading world, on-chain privacy is still hard. Mixers carry serious legal and sanctions risk, while simply rotating addresses only gives limited protection. Stealth addresses offer a different approach: generate a one-time receiving address for each incoming transfer at the protocol level, making it much harder for outside observers to link those receipts to the same recipient — all on-chain, without relying on third-party infrastructure.

What is a stealth address?
The core idea behind stealth addresses is straightforward: for each transfer, the sender uses the recipient’s public metadata — often called a stealth meta-address — to calculate a one-time address and sends funds there. Only the recipient has the corresponding keys and can scan the on-chain “announcement registry” to identify which one-time addresses belong to them.
From the outside, these one-time addresses do not show an obvious link to each other. An observer cannot reliably confirm that they belong to the same person.
In the Ethereum ecosystem, the main work in this direction includes ERC-5564, the stealth address standard, and ERC-6538, the stealth meta-address registry. These ERCs have been widely discussed in the Ethereum community and are gradually moving toward broader wallet and protocol adoption. The cryptographic implementations also build on mature standards such as EIP-712 structured signatures.
Stealth addresses vs. other privacy tools
The advantage of stealth addresses is that they extend privacy at the protocol and wallet layer. They do not require centralized infrastructure, and they do not work like mixers, which pool funds and redistribute them. From a technical design perspective, stealth addresses change how receiving addresses are generated rather than mixing assets across many users.
That distinction matters. It does not remove all compliance questions, but it does make stealth addresses a different privacy primitive from sanctioned mixer-style systems.
Why stealth addresses matter for perpetual DEX traders
On perpetual DEXs such as Hyperliquid and dYdX, your trading address can be tied to your full position history, PnL, deposits, withdrawals, and liquidation events. If that address is connected to your real identity — for example, because you once withdrew from a KYC exchange directly to it — your trading activity may be linkable to you.
Stealth addresses can help break part of that link in receiving flows. Instead of withdrawing directly to your main trading wallet, a sender can use your stealth meta-address to generate a one-time receiving address. That one-time address does not have a direct, visible on-chain relationship with the address you later use for DEX trading.
Major DEXs, including those with documentation similar to GMX’s current model, do not yet natively support stealth-address receiving as a standard user flow. But as Ethereum standards mature, wallet-layer support is expanding, which is where this technology is likely to become practical first.
How to use stealth addresses today
At the current stage, stealth addresses are mostly used through specialized wallets or tools that support the relevant standards. A typical workflow looks like this:
-
Generate a stealth meta-address
Use a wallet tool that supports ERC-5564, such as supported OneKey extension features when available, to generate and share your stealth meta-address. -
Ask the sender to use your meta-address
The sender calculates a one-time receiving address from your meta-address and sends funds to that address. -
Scan on-chain announcements
Use your scan key to check the on-chain announcement registry and identify funds sent to you. -
Move funds with your spending key
Once the funds are identified, use the spending key that only you control to transfer them to your operational wallet.
This process is not yet as simple as a standard wallet deposit. It can be operationally complex, and support varies by wallet, chain, and implementation. As wallet adoption improves, the user experience should become smoother.
Balancing privacy and security: practical tips
Improving privacy should never come at the cost of private key safety. If you use stealth addresses, keep these points in mind:
- Treat your spending key like a seed phrase. If it is exposed, you can lose control of the assets.
- Your scan key is less sensitive because it can identify funds but cannot spend them. Still, it should not be published casually.
- Do not sign transactions with your spending key on untrusted websites or unknown tools.
- Use a OneKey hardware wallet to store the private key associated with your spending key and keep your signing environment offline.
- Developers who want to follow implementation progress can monitor OneKey’s public OneKey GitHub repositories and official channels for updates on stealth-address-related standards.
For traders, a practical setup is to separate receiving privacy from trading execution: use stealth-address-compatible receiving flows where supported, move funds into a dedicated trading wallet, and then use OneKey Perps for decentralized perpetual trading while keeping custody under your own control.
Regulatory perspective: are stealth addresses legal?
Unlike mixers, stealth addresses have not been subject to the same kind of explicit regulatory sanctions as Tornado Cash. Their core mechanism changes address generation rather than pooling and redistributing funds. The EU MiCA text framework also does not currently include a specific ban on stealth address technology.
That said, regulatory views can change. ESMA crypto-assets’s ongoing focus on crypto-asset supervision shows that European regulators are continuing to refine their approach to privacy-enhancing technologies. Before using any privacy tool, you should understand and comply with the laws that apply in your jurisdiction.
FAQ
Q1: Do stealth addresses make me fully anonymous?
No. Stealth addresses help break the visible link between a recipient’s ongoing identity and a receiving address. But if the sender’s address is already tied to your identity — for example, a direct withdrawal from your KYC exchange account — the source of funds may still be traceable. Stealth addresses improve recipient privacy; they do not provide complete anonymity.
Q2: Which wallets support stealth addresses today?
Support for ERC-5564 is still emerging across mainstream wallets. OneKey is following Ethereum ecosystem standards as they develop. Check official OneKey channels for the latest feature availability before relying on any specific workflow.
Q3: Can a one-time stealth address still be tracked?
Yes. Activity on any individual one-time address is still public on-chain. What stealth addresses aim to hide is the link between that one-time address and a specific meta-address or real-world identity. Other metadata — such as IP data, timing patterns, withdrawal sources, or reuse habits — may still create links.
Q4: Do stealth addresses increase gas costs?
Slightly. The sender may need to submit an additional announcement to an on-chain registry contract, which adds some gas overhead. On L2 networks, this cost can be much lower and more practical.
Q5: If I forget to scan, are my funds lost?
No. The funds remain on-chain and do not disappear because you failed to scan. However, if you do not scan for a long time, it can become harder to manage which one-time addresses have received funds. A regular scanning routine is recommended.
Conclusion: a next-generation privacy primitive for on-chain trading
Stealth addresses are an important direction for on-chain privacy. Instead of relying on centralized services or mixer-style pools, they use cryptography at the protocol layer to improve recipient privacy. As Ethereum standards mature and wallet support expands, stealth addresses may become a more common building block for users who care about privacy and self-custody.
