Nash’s multi-party computation technology (MPC) keeps a user’s full private key secret. This means that connecting to dapps through our mobile app is considerably safer than using a browser extension!
Most people think blockchain transactions are signed with one all-powerful private key. But with MPC, Nash generates signatures using two sub-keys instead. One sub-key is held by the user, the other by Nash. This lets Nash add security features like withdrawal limits and address whitelists. If an attacker has obtained the user’s login details and tries to withdraw assets to an unapproved address, Nash can simply reject the transfer.
Because MPC never uses full private keys, it offers hardware-level security without any cost or fiddly UX. At the same time, because each sub-key is useless by itself, Nash cannot do anything with the user’s funds. It is a non-custodial solution.
The safest way to connect to dapps
Both the iOS and Android versions of the Nash mobile app are integrated with WalletConnect, making it easy to connect to dapps. And because your Nash mobile wallet is powered by MPC, you’re never using your full private key when signing dapp transactions – much safer than a browser extension!
For a long time, interacting with dapps meant running a browser extension wallet like MetaMask. Such wallets allow users to access whatever dapp infrastructure lies on the normal web while at the same time making a wallet available to interact with its blockchain-based smart contracts.
Using browser wallets comes at a cost, however. Browser wallets don’t offer an ideal user experience for generating and securely storing a seed. Many users prefer to keep their coins on hardware devices or within an existing wallet. Interacting with dapps hence means generating a new wallet in the browser and transferring funds across.
Of course, it’s also possible to copy a wallet’s private key into a browser extension, “connecting” it to a dapp – but this is far from an ideal solution. Not only can the process be fiddly, but it leaves a private key exposed for a certain amount of time. This is to say nothing about using dapps conveniently on mobile devices, or the relative ease with which fake wallet apps can steal user funds.
Thanks to WalletConnect, connecting to dapps on Nash is as simple as scanning a QR code. And with MPC powering your Nash wallet, you can be absolutely sure your funds are safe!
