Introducing Plurality's Smart Profiles Embedded Wallet With MPC TSS
By Alev • May 13, 2025
Smart Profiles have become an essential part of Web3 identity systems. However, few solutions combine user control and security at the technical level. Plurality Network’s embedded wallet uses MPC TSS to create secure, user-controlled Smart Profiles. By applying Multi-Party Computation (MPC) and Threshold Signature Scheme (TSS), Plurality solves major weaknesses in key management, data fragmentation, and identity verification. With MPC TSS, Smart Profiles are more secure and resilient without adding friction to the user experience.
Many users have seen or heard about Smart Profiles, but few realize how MPC TSS fundamentally upgrades them. Traditional wallets often rely on single-point private key storage, exposing users to theft or loss. Embedded wallets built on MPC TSS protect users by splitting key responsibility across multiple parties. Smart Profiles on Plurality now deliver strong Web3 authentication without centralized control, combining the benefits of decentralized architecture and practical usability.
Plurality’s approach with embedded wallets and MPC TSS creates a direct path toward secure identity frameworks. All thanks to MPC TSS tech, Plurality Network can provide social logins in a self-custodial way. Unlike older Web2 authentication models, these systems are designed to avoid centralized vulnerabilities from the beginning.
By embedding MPC TSS in Smart Profiles, users gain a Web3-ready identity layer that is secure, portable, and resistant to data fragmentation and key compromise. This is the structure needed for a sustainable decentralized internet and web3 wallets.
Why MPC TSS Tech is a Hype for Embedded Wallets?
MPC TSS is gaining traction for embedded wallets because it solves critical security and usability challenges. Embedded wallets traditionally rely on local or custodial key management models, which either put too much risk on users or introduce centralized points of failure. MPC TSS distributes the private key generation and signing process across multiple independent parties, removing reliance on any one device or provider.
“Notably, Plurality Network is the only solution powered by a decentralized MPC network.”
In Web3, users expect autonomy without compromising security. Embedded wallets using Multi-Party Computation and Threshold Signature Scheme ensure that no single party ever has full access to the private key. This setup removes a major attack surface while keeping authentication processes efficient. Plurality’s architecture with MPC TSS fits directly into the need for scalable and secure identity solutions in Web3 systems.
Another reason MPC TSS is critical for embedded wallets is how it improves key recovery. Losing a device no longer means losing access to assets. Because the private key never exists in full on one device, users can regain access through secure recovery protocols, a key benefit for mainstream Web3 adoption. Plurality Network’s embedded wallets use this to strengthen Smart Profiles and support broader ecosystem interoperability.
How Does It Contribute to Embedded Wallet Security?
MPC TSS strengthens embedded wallet security by decentralizing both private key storage and signing operations. In a standard wallet model, a hacker only needs to steal or compromise one key to gain control. With MPC TSS, a single compromised party does not expose the complete key, because private key material is mathematically divided and never fully assembled.
In Plurality’s embedded wallet model, MPC ensures that key shares are distributed across independent nodes or systems. TSS ensures that only a specific threshold number of parties are required to jointly sign a transaction. Even if several nodes fail or are compromised, the embedded wallet remains secure because the necessary threshold is still protected.
This design supports not only higher resistance against theft but also better uptime and resilience. If one or more nodes go offline, transaction signing can still occur through available threshold participants. Plurality’s use of MPC TSS provides embedded wallets with robust, fault-tolerant operations while maintaining complete user control.
Smart Profiles Powered Up With MPC TSS: A Technical Angle
When we state that Smart Profiles are powered with MPC TSS technology, it signifies a critical architectural advancement within the Plurality Core Protocol. This integration moves Smart Profiles beyond simple identity representations, embedding cryptographic resilience directly at the protocol layer. With Multi-Party Computation and Threshold Signature Scheme (MPC TSS) mechanisms in place, Smart Profiles inherit decentralized key management, distributed signing, and threshold-based recovery natively.
This means the user’s Web3 identity no longer depends on monolithic key custody but operates through collaborative, permissionless cryptographic operations across multiple nodes. As a result, Smart Profiles become not only secure identity anchors but also seamless authentication vehicles for decentralized ecosystems, aligning tightly with the principles of embedded wallets and universal Web3 Passports.
Breakdown of Features
- Key Sharding at Generation: Keys are generated in a distributed way, not generated and then split. This prevents full keys from existing at any point in the system.
- Threshold-Based Transaction Signing: Only a minimum number of parties (threshold) are needed to produce a valid signature, meaning compromised parties cannot forge transactions alone.
- Non-Custodial Recovery Options: Recovery processes can be initiated without exposing or reconstructing the private key in full, improving both security and user experience.
- No Single Point of Failure: Since no party holds the full key, compromising a single device or server is not enough to breach wallet security.
- Interoperability With Web3 Applications: Embedded wallets designed with MPC TSS can authenticate across multiple dApps securely, forming a unified Web3 Passport experience.
The Role of MPC TSS in Securing Next-Gen Embedded Wallets
Plurality Network’s focus on MPC TSS for embedded wallets reflects a shift toward building wallets that match the requirements of decentralized applications. Single-device wallets, whether local or custodial, cannot scale securely with Web3 systems. MPC TSS ensures next-generation wallets stay secure even as users interact across multiple platforms and devices.
The next phase of Web3 requires wallet solutions that do not ask users to trade convenience for security. By integrating Multi-Party Computation and Threshold Signature Scheme directly into wallet architectures, Plurality ensures that users get full control without taking on full technical responsibility. This model reduces onboarding friction and supports broader Web3 Passport functionality.
Technical Breakdown of MPC TSS in Embedded Wallets:
- Multi-Party Computation (MPC): Enables distributed private key operations without ever assembling a full key, securing against compromise.
- Threshold Signature Scheme (TSS): Uses a signing threshold to authorize transactions, even if some parties are unavailable or compromised.
- Distributed Recovery Protocols: Ensures users can regain access to their embedded wallet using partial shares and authorized flows without recreating the key in full.
- Device and Node Redundancy: Supports signing operations across a network of devices or nodes, maintaining uptime and resilience.
Web3 Passport With A Secure Architecture
Plurality’s embedded wallets do not just secure individual accounts — they create a full identity architecture for Web3 Passports. A Web3 Passport allows users to carry their identity, authentication rights, and account history across multiple decentralized applications without repetitive onboarding.
Because Plurality uses MPC TSS, the Web3 Passport is protected by decentralized key generation and signing methods. Users do not have to store full keys locally or depend on centralized services for authentication. The Smart Profile attached to an embedded wallet becomes a portable, verifiable identity layer.
This architecture eliminates the clunky experience of password resets, account lockouts, and insecure cloud backups. Instead, users gain a unified experience with user context where embedded wallets and Smart Profiles are seamlessly used across Web3 environments with guaranteed security properties.
Conclusion
Plurality Network’s embedded wallet system, built with MPC TSS, sets a new benchmark for Web3 authentication and identity management. By removing single points of failure, enhancing recovery options, and ensuring scalable transaction signing, Smart Profiles become much more than simple user accounts.
With Multi-Party Computation and Threshold Signature Scheme integrated from the ground up, Plurality creates a secure, user-first Web3 Passport architecture. This is critical for the future of decentralized applications where security, portability, and user ownership are non-negotiable.
