ONTO Wallet, a decentralized, self-custodial multi-chain wallet, has integrated StealthEX, an instant non-custodial cryptocurrency exchange. ONTO users can now exchange more than 2,000 cryptocurrencies and tokens directly inside the wallet, with the project teams stating that the StealthEX exchange fee for swaps through ONTO Wallet is $0.4.

The integration combines the strengths of both platforms. Users gain a wide choice of supported assets, instant non-custodial swaps that StealthEX describes as limitless, and a low cost per swap, while keeping control of their funds throughout, since StealthEX does not hold assets on its platform at any stage.

StealthEX is an instant cryptocurrency exchange that lets users swap digital assets without creating an account. Its swaps move directly from wallet to wallet, so the service never takes custody of user funds. ONTO Wallet already enables people to manage assets across multiple blockchains, connect to decentralized applications (dApps), and use decentralized identity. The StealthEX integration adds broader exchange options to that feature set, so users can manage and swap their crypto in the same place.

ONTO Wallet and StealthEX: More Exchange Options in One Interface

Under the partnership, StealthEX is now available inside ONTO Wallet as an exchange solution. Through the integration, users can access the more than 2,000 cryptocurrencies and tokens supported by StealthEX and swap between them from the wallet interface.

Before integrations of this kind, swapping one asset for another often took several steps: a user might have to visit a separate exchange website, copy deposit addresses between apps, and track the transaction in another tab. Now the exchange step sits inside the wallet the user already relies on. Users do not have to visit a separate exchange website or create an exchange account, and they can follow the process from a familiar interface.

This matters most in a multi-chain wallet. ONTO users often hold assets on several blockchain networks, and having exchange tools next to those holdings makes it easier to rebalance a portfolio, obtain a token needed for a particular network, or convert assets for a dApp.

Each partner contributes a different piece:

• ONTO provides the wallet infrastructure. That includes private key management on the user's device, multi-chain asset management, and the interface users interact with.
• StealthEX provides the exchange technology. It connects to multiple liquidity providers to find available rates for supported trading pairs and carries out the swap.

ONTO's approach to exchange services is built on user choice. The wallet works with several exchange service providers, and using any of them is optional. StealthEX adds another option to that lineup, along with its own asset coverage and fee structure.

Wide Asset Coverage and a $0.4 Exchange Fee

The integration has two main financial benefits: broad asset coverage and a low cost per swap.

Broad Asset Coverage

StealthEX supports more than 2,000 cryptocurrencies. These range from widely held assets such as Bitcoin and Ether to tokens from smaller and newer ecosystems, giving ONTO users considerably more choice when they swap from their wallet.

Availability still depends on several factors. Not every asset or trading pair is supported on every blockchain network, and which pairs are open at a given moment depends on the supported networks, liquidity, and the minimum exchange amounts for each pair. Users should check the available assets and networks in the exchange interface before starting a swap.

A $0.4 Exchange Fee, Separate From Other Costs

According to the project teams, the StealthEX exchange fee for swaps through ONTO Wallet is $0.4, making the integration an affordable way to swap digital assets. The fee is separate from other costs a swap can involve:

• Network fees. Sending assets on a blockchain requires a network (gas) fee. The network sets this fee, not StealthEX or ONTO, and it changes with network activity.
• Exchange rates. The amount a user receives also depends on the exchange rate for the chosen pair, which differs between fixed-rate and floating-rate swaps.

Users should review the full quote shown before confirming a swap. The quote displays the amount they will send and the estimated amount they will receive.

Why Crypto Swap Fees Matter

Crypto swap fees can add up quickly, especially for people who exchange often. Someone who rebalances across several networks, moves funds into tokens for different dApps, or makes many small swaps can lose a meaningful share of their activity to fees. Percentage-based fees grow with the size of each trade, and fees set by individual services can vary widely across the non-custodial exchange market. A flat fee works differently: it stays the same regardless of trade size, so it weighs more heavily on a small swap and less heavily on a large one. Because the service fee is known before a swap starts, a flat fee also makes the total cost of a series of exchanges easier to estimate in advance.

A low exchange fee helps keep those costs predictable. At $0.4, the StealthEX fee is one of the most competitive in the non-custodial exchange market, and it is especially relevant for ONTO users who manage assets across multiple blockchain networks and swap regularly.

What Is StealthEX? A Non-Custodial Instant Crypto Exchange

StealthEX is an instant, non-custodial cryptocurrency exchange. It supports more than 2,000 coins and tokens, and users can exchange them without creating an account. Its key features are:

• Non-custodial architecture. StealthEX does not store users' funds or private keys on the platform. Swaps go from wallet to wallet: the user sends the asset they want to exchange, and the exchanged asset goes straight to the wallet address they provided.
• No account required. Users do not need to register, set up an exchange account, or keep a balance on the platform.
• Multiple liquidity providers. StealthEX works with several liquidity providers to find available exchange rates for supported trading pairs.
• Fixed and floating rates. Where available, users can lock in a fixed rate when the swap starts or use a floating rate that follows the market while the swap is processed.
• A simple process. Users pick the assets, enter an amount, provide a receiving address, and complete the transfer.

Non-custodial exchange services matter more as users pay closer attention to who controls their assets. On a custodial platform, users deposit funds into an account that the platform manages. A non-custodial service never holds user funds in an account, so users keep control of their assets before and after each swap. For people who prefer self-custody, this lets them exchange crypto without giving up control of their holdings.

StealthEX also offers integration tools for wallets, aggregators, and other crypto products; its partnership with ONTO Wallet is one example.

What Is ONTO Wallet? A Multi-Chain Web3 Ecosystem

ONTO Wallet is a decentralized, self-custodial multi-chain wallet built as a gateway to Web3. It is available as a mobile app and as a browser-based web wallet. Private keys are generated on the user's device, so ONTO cannot access them and users keep full control of their assets.

ONTO's main features include:

• Multi-chain asset management. Users can manage digital assets on multiple blockchain networks, including Ethereum, BNB Chain, and Ontology, from a single interface.
• Cryptocurrencies and NFTs. The wallet supports both fungible tokens and NFTs.
• dApp access. Users can connect to decentralized applications and explore Web3 services, from DeFi platforms to NFT marketplaces.
• Decentralized identity. ONTO includes decentralized identity (DID) features through ONT ID. Users can create a portable digital identity, use it to log in to applications, and manage their personal data.
• Hardware wallet support. ONTO supports Ledger hardware wallets, giving users another way to secure and manage their digital assets.

These features make ONTO more than a place to store crypto. It combines asset management, identity, and access to decentralized services in one app, and its multi-chain design is useful for people who work across several blockchain ecosystems and would otherwise need separate tools for each.

Why the StealthEX Integration Matters for ONTO Wallet Users

The integration brings together the strengths of both platforms. For ONTO Wallet users, the practical benefits are:

• More exchange options. Users can reach the more than 2,000 cryptocurrencies and tokens supported by StealthEX.
• Lower costs. The $0.4 StealthEX exchange fee makes swapping more affordable, particularly for frequent users.
• Convenience. Exchange tools are available inside ONTO Wallet, so users do not need a separate exchange website.
• Self-custody. StealthEX is a non-custodial crypto exchange, so it never holds user funds on its platform, while ONTO's self-custodial design keeps private keys on the user's device.
• Multi-chain flexibility. A wider choice of supported assets and pairs suits users who manage holdings on different networks.
• Simpler crypto management. With storage, dApps, and exchanges in one place, users switch between fewer apps and have fewer manual steps to manage.

The integration works for both experienced and newer users. Experienced users who manage diverse portfolios get broad asset coverage and a predictable fee, while users still exploring different blockchain ecosystems get a simpler way to obtain the tokens they need without learning a separate platform.

Making Cryptocurrency Exchanges More Accessible

The partnership reflects a wider trend: wallets are increasingly integrating non-custodial exchange providers, making crypto exchanges more accessible, affordable, and convenient within the Web3 experience.

The structure of this integration shows how that trend works in practice. StealthEX offers integration tools for wallets, aggregators, and other crypto products, and ONTO's multi-provider exchange lineup means StealthEX sits alongside existing options rather than replacing them. As exchange features become a standard part of what wallets offer, the points of comparison between providers are asset coverage, fee structure, rate options, and custody model — the same dimensions this integration brings together.

Users now expect wallets to do more than store and send assets. A modern wallet is often where people check balances, connect to applications, manage NFTs, and make swaps. Having exchange tools, dApps, and multi-chain services in one ecosystem means fewer platforms to deal with and fewer chances for manual errors, such as copying the wrong address between apps.

Combining a self-custodial wallet with a non-custodial exchange also keeps self-custody intact. Users can exchange assets inside the wallet while keeping control of their funds.

Conclusion

ONTO Wallet has integrated StealthEX, so ONTO users can now exchange over 2,000 cryptocurrencies directly in the wallet with a $0.4 StealthEX exchange fee.

The two platforms complement each other. ONTO provides a self-custodial multi-chain wallet with decentralized identity, NFT management, dApp access, and Ledger support, while StealthEX provides instant, non-custodial crypto exchange technology with broad asset coverage and both fixed and floating rates.

Both teams aim to keep making cryptocurrency exchanges more accessible and affordable. The integration is a step toward a Web3 experience where users can manage, use, and swap digital assets in one place while staying in control of their funds.
