Ika and Human Tech Unveil Zero-Trust Wallet-as-a-Protocol Infrastructure: A New Paradigm for Decentralized Wallets
In a landmark announcement from Zug, Switzerland, on October 22nd, 2025, Ika and human.tech have jointly introduced a new category of decentralized wallet infrastructure that promises to redefine user sovereignty and security in the crypto space. This partnership unveils Wallet-as-a-Protocol (WaaP), a foundational shift away from traditional Wallet-as-a-Service (WaaS) models, secured by Ika's breakthrough 2PC-MPC cryptography. For the first time, wallet logic, key management, and access control are being decentralized across a zero-trust network, moving wallet functionality from a centralized service to a decentralized protocol on Sui.
From Wallet-as-a-Service to Wallet-as-a-Protocol: The Fundamental Shift
The prevailing model for application-integrated wallets has been Wallet-as-a-Service (WaaS). These solutions have provided developers with a streamlined way to embed wallet functionality but at a significant cost: they grant the apps full control over user wallets. This architecture has inherently introduced custodial risks and security vulnerabilities. Furthermore, it has created a siloed experience where a wallet created within one application could not be used seamlessly in another, leading to vendor lock-in and fracturing the user's identity across the digital landscape.
With the introduction of WaaP, human.tech and Ika are replacing this model entirely. The core innovation lies in its decentralized nature. A user's key share remains local to their device, while Ika's decentralized network operates the co-signing share under strict zero-trust conditions. Critically, no single entity—not even human.tech—can access or reconstruct the full private key. This transforms the Human Wallet from a service provider into open, decentralized infrastructure, enabling what the companies term "universal accounts" that work across dApps, devices, and chains.
The Technology Behind WaaP: Understanding 2PC-MPC
The engine powering this new infrastructure is Ika’s 2PC-MPC (Two-Party Computation Multi-Party Computation) protocol. This cryptographic breakthrough addresses key limitations of previous MPC implementations by splitting private keys into two independent cryptographic shares:
- User Share: This share is held and authorized locally by the user on their device.
- Network Share: This share is operated by Ika’s decentralized 2PC-MPC network.
For any transaction signature to be generated, both shares are required. The protocol is designed so that the full private key is never reconstructed at any point, not even during the signing process. This creates a genuine zero-trust signing environment that is resistant to both local device compromise and potential collusion at the network level. According to Ika Co-Founder David Lachmish, "2PC-MPC changes what a wallet can be. It removes unilateral control, scales to real-world throughput, and for the first time, makes decentralized, flexible and secure wallets practical at the infrastructure level." By migrating its signing layer to Ika, human.tech becomes the first wallet provider to decentralize programmable security and access control using a global, zero-trust MPC network.
Why It Matters: Establishing a New Security Standard
The implications of this partnership extend far beyond a simple product update; it establishes a new architectural standard for wallets in the Web3 ecosystem. The WaaP model introduces several foundational improvements:
- Decentralized Security: It systematically removes single points of failure. There is no reliance on a centralized service's custody or a singular secure enclave that could become a target.
- Censorship Resistance: Because no single entity controls the wallet or the signing process, no one can unilaterally block or forge user transaction intent.
- Zero-Trust UX: Users benefit from human-readable intent validation while maintaining secure policy enforcement directly at the cryptographic signing layer.
- Protocol-Level Composability: This enables one universal wallet identity to operate across countless applications without the need for iframe custody models or per-wallet licensing fees.
A New Foundation for Builders and Developers
For developers, WaaP is designed to be both powerful and simple to integrate. The infrastructure is universal and generic, with stated support for Bitcoin and Solana. It is also fully EIP-1193 compliant, allowing developers to integrate the Human Wallet using the same provider interface that is standard across Ethereum and other EVM-compatible ecosystems. The companies promise integration times of minutes, supported by copy-paste quick start examples and a dedicated developer portal.
By adopting WaaP, developers can offer users seamless onboarding experiences without sacrificing security. They gain access to advanced features like programmable transaction policies, gas fee sponsorship capabilities, and multi-factor authentication (MFA), all enforced cryptographically at the wallet layer rather than through trusted intermediaries.
A New Era for Secure User Experience
Historically, Web3 has struggled with the trade-off between security and user experience. Advanced self-custody solutions often come with complex seed phrase management, while user-friendly embedded wallets sacrifice decentralization and user sovereignty. The WaaP model, as described by human.tech Co-Founder Nanak Nihal Singh Khalsa, aims to resolve this conflict: "Wallet-as-a-Protocol is what Wallet-as-a-Service wanted to be. It gives users ownership, developers composability, and the ecosystem a path to eliminate trusted intermediaries – all made possible by 2PC-MPC."
This approach unites user sovereignty with developer simplicity, enabling security and scalability suitable for mass adoption. Combined with Ika's MPC network built on the Sui blockchain, the WaaP infrastructure's potential extends into cross-chain coordination, effectively making decentralized security and broad interoperability synonymous.
Conclusion: Paving the Path for an Interoperable Web3 Future
The unveiling of Wallet-as-a-Protocol by Ika and human.tech represents a significant evolution in digital asset infrastructure. By decentralizing the core components of wallet functionality—key management and access control—this partnership challenges the centralized custodial risks that have persisted even in some "non-custodial" models. It provides a tangible technical pathway toward a Web3 environment where users have true ownership of their universal identity across applications and chains, while developers can build without being limited by walled-garden wallet services.
For the broader market, this development highlights a continuing trend towards chain abstraction and interoperability, where the underlying blockchain becomes less visible to the end-user without compromising on core decentralization principles. Readers and builders in the space should watch closely for early developer adoption metrics and security audits of the 2PC-MPC protocol. The success of WaaP could set a new benchmark, prompting other wallet providers and infrastructure projects to explore similar decentralized models, ultimately accelerating the industry's move away from trusted third parties and toward a more seamless, secure, and user-centric ecosystem.
