Fluidkey, the self-custodial wallet leveraging advanced stealth address technology, has enhanced its capabilities by integrating with BNB Chain. This update, included in the iOS app version 1.68.0 released on June 12, positions BNB Chain as the seventh EVM-compatible blockchain available to users. This allows for the reception of funds into unlinkable addresses, and the ability to convert these into traditional bank transfers.
The wallet operates on a dual infrastructure model consisting of stealth addresses that provide user privacy, and Safe smart accounts that manage custody and programmability. This ensures that users retain control of their assets, while minimizing the visibility of transactions on the public blockchain.
With the inclusion of BNB Chain, Fluidkey now offers transaction capabilities across a range of networks, including Ethereum, Arbitrum, Base, Polygon, Optimism, Gnosis, and BSC. The platform also features integrated bridges, supporting bank transfers for US dollar transactions via ACH, and euro transactions through SEPA/IBAN, with settlements occurring in USDC or EURC.
To date, Fluidkey has enabled transfers exceeding $840 million across its supported networks, serving over 24,000 users as of June 2026. This impressive figure translates to an average transfer of around $35,000 per user, highlighting the platform's effectiveness.
In addition to single-chain functionality, Fluidkey facilitates cross-chain deposits through Near Intents. This functionality permits users to transfer BTC, USDC, and USDT from ten additional chains, which can then arrive in a stealth address located on any of Fluidkey’s seven active networks.
Despite these advancements, regulatory risks remain a concern for privacy-focused tools. Even though stealth addresses differ from mixing protocols, there is a notable lack of precision in regulatory definitions. Any regulatory actions targeting stealth address technologies could pose challenges for Fluidkey and similar ventures. Investors in this domain should closely monitor not only user adoption and transaction volumes, but also how authorities in the US and EU categorize stealth address wallets within existing anti-money laundering frameworks.
