Human.tech has officially launched its Wallet-as-a-Protocol (WaaP) infrastructure on the Sui blockchain, introducing a decentralized wallet execution layer to the network. This integration enables developers building on Sui to embed self-custodial wallets directly into their applications, eliminating reliance on centralized wallet providers while maintaining cryptographic security.
The WaaP protocol allows for wallet creation using familiar authentication methods such as email, phone number, Google login, or biometric verification. Despite this simplified user experience, the architecture ensures that no single entity can independently access or control user funds. Unlike Wallet-as-a-Service (WaaS) models that depend on vendor-operated infrastructure, WaaP functions as an open protocol, removing platform dependency and long-term lock-in for developers.
According to Human.tech, WaaP addresses common tradeoffs in embedded wallet solutions by shifting enforcement logic from centralized servers to smart contracts. The protocol runs on Ika, a coordination layer built on Sui that enforces transaction policies on-chain. Signing authority is divided through two-party computation (2PC-MPC) between the user's device and Ika's decentralized validator network, meaning neither side can execute transactions independently.
Policy controls such as spending caps, contract allowlists, or approval thresholds are enforced cryptographically during transaction signing. This model aims to combine simplified onboarding with hardware-grade security characteristics while reducing custody risk for application developers.
Human.tech reports that its broader infrastructure already supports nearly 3 million verified users and has issued more than 43 million credentials, securing over $500 million in value across applications. The WaaP integration extends this infrastructure to Sui, which ranks among the leading blockchains by total value locked and decentralized exchange activity.
The architecture also lays the groundwork for programmable wallet features, including delegated execution and automated workflows. As on-chain automation and AI-driven agents expand, the model is designed to enable scoped permissions while preserving user-level control. WaaP is currently available to developers building on Sui, with documentation accessible through the protocol's developer portal.
