Crypto.com’s self-custody wallet branding is centered on Onchain, previously known to many users as the DeFi Wallet. The official Crypto.com Onchain page describes it as a non-custodial, multi-chain wallet that lets users take control of keys while accessing a suite of onchain services.
This review uses “Crypto.com wallet” to mean that self-custody Onchain product, not the custodial balances held inside the Crypto.com App.
The distinction matters. Self-custody means the recovery phrase controls access. No support agent can “reset” it. No third party can reverse transactions. That autonomy reduces exchange custody risk, but it also makes user mistakes permanent.
Crypto.com frames Onchain as self-custodial. That means private keys are controlled by the user, and the recovery phrase is the custody anchor.
The strongest security feature is therefore not a toggle. It is the backup. A recovery phrase stored offline, separated from daily devices, is the difference between recoverable and unrecoverable mistakes. A recovery phrase stored digitally becomes a hack waiting to happen.
Crypto.com’s product messaging reinforces the non-custodial model across multiple pages, including its region-specific Onchain pages, and it positions onchain services as accessible without handing custody to the platform.
Onchain exists as a mobile wallet and as a browser extension.
The extension model is designed for Web3. It enables dApp connections, approvals, and token swaps directly in the browser. This is convenient, but it expands exposure to phishing sites and malicious dApp prompts. A browser wallet is a higher-value target, especially when users install multiple extensions.
The mobile app model is often simpler for storage and occasional transfers. Phones can still be compromised, but mobile wallets typically face fewer browser-based attack patterns. For many users, the safest setup is to use mobile for long-term holding and the extension for controlled dApp interactions, with strict segmentation between accounts.
Crypto.com markets Onchain as supporting thousands of tokens across dozens of chains.
The help article about the extension describes support for over 4,000 tokens across multiple blockchains, including Bitcoin, Ethereum, Cronos, and many Layer 2 chains. The Onchain product page also calls out major chains directly, listing multi-chain management across Bitcoin, Ethereum, Solana, and Cronos.
Coverage still needs verification for long-tail assets. Many losses occur when users assume a token is supported on a specific network and send it in the wrong format. A safer approach is to verify the chain and token standard, then send a small test amount before moving significant value.
Onchain offers a mainstream funding path. The app store description for the Crypto.com Onchain Wallet iOS app describes linking a Crypto.com account to buy tokens using Apple or Google Pay or bank transfers, and it references an in-app bridging tool for moving assets.
This can reduce friction for users who want to go from fiat to self-custody without using multiple apps. The key mechanism is that convenience features increase the number of steps in a flow. More steps create more opportunities for selecting the wrong network, accepting the wrong route, or trusting the wrong prompt.
Users should treat “easy funding” and “easy bridging” as features that require verification discipline, not as automated safety.
Onchain includes swapping and bridging utilities. Swaps are ultimately a routing and liquidity problem. Quotes vary across venues and routes, and execution can worsen under volatility. Bridging adds another layer: it depends on bridge design, liquidity, and finality assumptions.
Crypto.com continues to expand Onchain as a product surface. Crypto.com’s product news includes updates such as a revamp announcement for the extension in Introducing the new Crypto.com Onchain Extension, and it describes broader expansion into onchain web experiences in the product update about launching an Onchain website domain.
The security takeaway is straightforward. The more a wallet becomes a portal to onchain activity, the more the user must evaluate risk per action. Swaps and bridges can be safe tools, but they are also the most common moment where users sign approvals they do not fully understand.
Most modern wallet losses are not pure key theft. They are malicious approvals. A wallet extension connects to dApps. dApps request permissions. Some permissions allow token transfers later.
Users who approve unlimited spending on unknown contracts increase risk substantially. The safest operational habit is to approve only what is needed, revoke permissions periodically, and segment accounts.
A strong segmentation model has two parts. A primary “vault” account should do minimal dApp activity. A separate “activity” account should handle experimentation, mints, and airdrops.
Wallet privacy depends on data sources. If a wallet relies on third-party RPC providers, queries can leak metadata. If it relies on in-house infrastructure, users still depend on that infrastructure for reliability.
For most users, the practical privacy goal is reducing unnecessary linkage. Using new addresses where appropriate, avoiding needless consolidation, and separating accounts by purpose typically matter more than any single privacy claim.
The most common mistake is seed phrase mishandling. Digital copies, screenshots, and synced notes are the top failure pattern across self-custody wallets.
Another common mistake is signing too fast. A wallet with built-in discovery and swapping can create approval fatigue. Fatigue makes users click through warnings.
A third mistake is bridging without understanding the route. Bridge selection, chain finality, and liquidity can affect whether funds arrive quickly, arrive late, or arrive with extra fees.
Crypto.com Onchain fits users who want self-custody with a mainstream user experience, including simple funding paths and broad multichain support. It can be a strong fit for users who want to explore DeFi while maintaining control over keys.
It is a weaker fit for users who want minimalism. Feature-rich wallets work best when users already have strong operational habits. For long-term storage, pairing a wallet with a hardware wallet, or using hardware for the vault account, can reduce hot wallet exposure.
Crypto.com’s self-custody wallet in 2026, branded as Onchain, offers a broad multichain experience across mobile and browser extension, with convenient funding options and clear dApp access. Its value is usability with a self-custody model, allowing users to keep control of keys while still using onchain services.
The main risks come from user behavior and onchain complexity. Users who keep backups offline, segment vault and activity accounts, and verify every swap, bridge, and approval tend to get the best outcomes from Onchain’s expanded feature set.
