Decentralized Wallet Network (DWN)
The Decentralized Wallet Network (DWN) is a network of secure, independent nodes that collectively manage user wallets in a trust-minimized manner. Instead of treating a wallet as a basic “bank account” on just one or two networks, the DWN abstracts the underlying complexities so a single wallet can function across multiple chains—Ethereum, Solana, Aptos, and many others.
Core Functionality
The DWN's primary function is to provide a secure and decentralized infrastructure for managing user wallets across multiple blockchains. It eliminates the fragmentation and security risks associated with traditional wallet solutions in a multi-chain environment.
Key functionalities include:
-
Unified Multi-Chain Wallet Experience: Provides users with a single wallet interface to access and manage assets across multiple blockchains, including EVM and non-EVM chains (e.g., Ethereum, Solana, Aptos).
-
Decentralized Key Management: Employs Multi-Party Computation (MPC) and Threshold Signature Schemes (TSS) to distribute private key management across a network of decentralized nodes, eliminating single points of failure and enhancing security.
-
Trust-Minimized Operation: Operates in a trust-minimized manner, ensuring that no single entity, including Okto, has unilateral control over user funds or private keys.
-
User-Friendly Onboarding: Supports Web2-style authentication methods (e.g., Google OAuth, Email OTP, Phone OTP), simplifying user onboarding and eliminating the need for seed phrase management.
-
Secure Transaction Signing: Coordinates a decentralized network of MPC nodes to securely sign transactions on behalf of users, ensuring cryptographic security and user consent.
Architecture and Technology
-
Multi-Party Computation (MPC)
- A quorum of MPC nodes (e.g., 11 of 20) must collaborate to sign a transaction.
- Eliminates single points of failure—no single party (including Okto) can unilaterally move user funds.
- Uses a Threshold Signature Scheme (TSS) so that each node only holds a share of the cryptographic key.
-
EigenLayer AVS (Actively Validated Services)
- DWN nodes run as services on EigenLayer, inheriting Ethereum’s restaking security.
- Economic Deterrent: Operators stake substantial assets; any malicious action puts that stake at risk across the EigenLayer ecosystem.
- Decentralization: Independent operators provide infrastructure, preventing collusion.
-
Trusted Execution Environments (TEEs)
- Each MPC node runs inside a TEE such as Intel SGX, isolating sensitive cryptographic operations from the broader system.
- Even if an operating system is compromised, the cryptographic key shards remain protected.
-
Cross-Chain Compatibility
- EVM and non-EVM networks are supported: Ethereum, Solana, Aptos, Cosmos, and more.
- Works seamlessly with EOA wallets, ERC-4337 contract wallets, magic accounts, and social logins.
DWN + Embedded Wallets
Developers can integrate DWN-powered embedded wallets using Okto’s SDKs. These wallets offer:
- Interoperability: A single wallet interface across multiple chains.
- Flexibility: Can be used as a closed-loop or interoperable wallet.
- Simplified UX: Users interact with dApps without switching wallets.
