Let’s start with the basics. What is a multichain wallet? It is just what it sounds like: It’s one wallet that allows interactions with assets and apps from multiple chains without manually juggling multiple crypto wallets.
A multi crypto wallet brings together different networks in one interface, so you can manage, send, and receive assets without switching tools or remembering which app belongs to which chain. Simple, right?
A multichain wallet connects to various blockchains via their APIs or direct node integrations. It uses protocol integration to show you all the balances, initiate transactions, and track activity across multiple networks. To make all this work, the wallet stores multiple private keys or seed phrases — each one tied to a different blockchain.
Now, here’s where things get interesting. In fact, blockchains were not designed to communicate with each other because most capacity is reserved for internal communication between nodes and apps. Therefore, they need extra tools to share information across networks.
Multichain wallets “translate” the messages of the different blockchains and show them in one interface. In this case, the wallet acts as an “oracle” that gathers info from various network explorers.
However, you can not only view your balances but also swap assets and initiate transactions on multiple chains without lifting a finger to manage the chains. That’s possible thanks to DeFi bridges and routers, but the wallet does it automatically with the best fees possible instead of the user.
From the user's perspective, multichain wallets bring plenty of benefits. With it, one can access all the assets across multiple chains that are displayed, manageable and can be exchanged. For example, you can swap your BNB assets to Solana assets without a sweat instead of bridging your assets or using a CEX to do so.
The convenience here is massive: fewer logins, fewer interfaces, fewer chances for user error.
Not all multichain wallets & apps are built the same way — here’s the breakdown of the key differences between them:
These wallets put the user entirely in control. You hold the private keys, meaning you truly own your assets. These multichain wallets best fit those who put privacy and decentralization above everything else. However, convenience may not be the strongest point of non-custodial wallets.
That’s where NonBank sets itself apart. We have self-custody principles of non-custodial wallets plus seamless user experience on 8+ chains, Non-Fee transactions, and dedicated wallets for different needs. It’s full DeFi, minus the complexity.
These wallets hold the users’ private keys and are responsible for their funds. The upside is that these multichain wallets are built simpler and beginner-friendly. The downside is that users don’t have full control over their funds. Think of blocked accounts, bankruptcies and other crises that central authorities are prone to.
This is Metamask and other similar solutions for multichain crypto management for browser extensions. They are fast, simple, and offer flexible connectivity across most chains.
As for mobile, NonBank stays in this niche, as users can manage assets of 8+ chains and interact with DeFi on the go.
Multichain apps
DEXs, DEX aggregators, staking platforms and other financial apps are the best representatives of the multichain blockchain app segments. They offer users a robust way to swap their assets or earn with them on any supported chain without hassle.
The wallets are evolving and becoming multichain — blockchain apps are not biting the dust and are embracing multichain technology, too. There are decentralized exchanges (DEXs), yield farming platforms, and many other dapps that offer services on multiple chains from a single interface.
Multichain wallets make life in Web3 more convenient. With it, users can swap tokens across chains — like Polygon to Gnosis — without ever touching a bridge. No extra steps, no waiting around. Just click, sign, and done.
Want to explore a multichain DeFi app or keep a close eye on all your crypto assets without opening three different dashboards? Multichain wallets provide you with access to everything in one interface — and not just your tokens, but the apps too.
In the past, it required keeping tabs on different wallets and platforms — now it’s a matter of what wallet the user will choose.
Everything comes with risks in crypto, even the most convenient tools like multichain wallets and dapps. One of the most common and obvious exploits is smart contract vulnerabilities. These may occur on the side of the wallet, as well as due to the poor code of the apps the user interacts with.
Cross-chain bridge exploits have become a particular concern in recent years. Since bridges act as connectors between blockchains, they are high-value targets for attackers. A vulnerability in just one component can jeopardize funds across multiple chains simultaneously.
Then, there’s the rise of fake apps and phishing attacks. As multichain wallets grow in popularity, so does the number of malicious clones and websites designed to steal private keys or seed phrases under the guise of being legit.
For multichain wallets, risk mitigation strategies aren’t that different from any other crypto wallet. Three fundamental principles apply:
First, don’t keep all your assets in one place. Multichain wallets are convenient, but storing everything in a single wallet creates a single point of failure. Distribute your assets across different wallets or cold storage solutions so the potential hack will have a lower impact.
Second, always double-check what you’re signing. Many exploits in DeFi come from malicious smart contract approvals that grant unlimited access to your assets. Make sure you understand what permissions you grant before confirming an approval or signing a transaction.
And third, be cautious about what you download and connect to. Thousands of malicious apps and websites are designed to mimic popular wallets, meaning users must verify that any wallet app or browser extension is legitimate before installation.
Sticking to wallets with strong security audits, transparent open-source code, and biometric or two-factor authentication options can go a long way in keeping your assets safe. And as always, your seed phrase should never be stored online — keep it offline, encrypted, and in a safe place.
The future is looking... well, multichain. With multichain exchanges, multi cryptocurrency wallet ecosystems, and blockchain apps racing toward better interoperability, we’re entering a new chapter for Web3.
Modern blockchain networks are designed with interoperability as a core principle. Unlike older chains built without it, newer ecosystems aim to connect and collaborate from the launch.
Perhaps soon we’ll see not multichain apps but multichain superapps. These will offer way more than just holding and swaps. They’d combine all DeFi ecosystems — imagine DEXs, aggregators, lending platforms, staking dashboards, NFT marketplaces — into a single, user-friendly app. This would allow users to manage assets, earn yield, swap tokens, and interact with dapps across ten chains without leaving their wallets.
That’s just the kind of superapp we’re building in NonBank.
Expect to see more:
In short, the future of Web3 may not just be multichain — it might be multiservice, multidimensional, and radically more user-friendly.
Whether you're a beginner managing a few coins or a power user trading across ten chains, multichain wallets make life easier. And expect it not only to be limited to the wallet, as the whole of Web3 slowly but steadily approaches the multichain.
So, next time you're tired of switching apps or stressing over bridges, ask yourself: Why struggle when one wallet can do it all?
