dNexus
One account, across digital worlds.
Universal smart account
We shaped dNexus around a universal smart account for assets, identity and services, developing web and mobile interfaces alongside an account core with coordinated transaction signing.
Our contribution
- Web and mobile interfaces
- Universal-account architecture
- Authentication and account access
- Shamir-based secret sharing
- ECDSA MPC signing
- Cosmos and Ethereum/EVM connectivity
The challenge
An account spanning chains needs more than a common interface. It needs to connect authentication, signing and wallet integrations while giving people a coherent way to manage their assets.
Our approach
Shamir secret sharing split key material into shares. ECDSA multiparty computation (MPC) let participants cooperate to produce a transaction signature. We joined those local and remote signing components with shared account authentication, wallet integrations and web and mobile interfaces.
The result
The account connected onboarding and access with transaction signing across the Cosmos and Ethereum/EVM ecosystems. Web and mobile applications shared the same account core, bringing the multichain experience into a common interface.
