Sui developers can now embed self-custodial wallets through WaaP
Sui developers can now embed self-custodial wallets with familiar login, programmable security, and no per-user fees. This is what embedded wallets should have been from the start.
WaaP (Wallet-as-a-Protocol) – launches on Sui, a high-performance blockchain delivering the full stack for a new global economy. This makes WaaP the first decentralized embedded wallet layer available to Sui developers.
"Using an embedded wallet shouldn't require giving up ownership," said Evan Cheng, Co-Founder and CEO of Mysten Labs, the original contributor to Sui. "With WaaP native to Sui, developers and users both get a brand new way to access the chain."
The problem with embedded wallets today
Embedded wallets solved the seed phrase problem. But most solutions created new ones.
Developers offload custody risk to the wallet provider. Users lose true ownership. Applications become dependent on vendor infrastructure that can change terms, raise prices, or shut down. And wallets stay siloed per application, with no continuity across the products your users actually use.
WaaP removes those tradeoffs.
How it works
Two-party computation (2PC) splits signing between the user's device and a protector enclave. Neither party can move funds alone. Policy controls, such as spend limits, contract allowlists, approval thresholds — are enforced on-chain, not in a backend you have to trust.
We call this protected self-custody. The security model sits at the signing layer, not the client. Users get a seedless wallet backed by email or Google login. Developers get embeddable infrastructure with no custody liability.
For Sui developers
WaaP works with Mystenlabs dapp-kit and is auto-discovered in wallet selection. Users sign in with email, Google, or other social accounts. No seed phrases. No per-user fees. No subscriptions.
Builders also share in revenue from user activity on the protocol.
Integration takes minutes. Docs at docs.waap.xyz.
What's coming: Squid Mode
We're building toward something bigger. Squid Mode — WaaP's fully decentralized signing layer will be powered by Ika's 2PC-MPC protocol, live on Sui. Ika uses Sui as a censorship-resistant coordination layer for its distributed validator network. When live, the enclave is replaced entirely: signing authority is distributed across a decentralized network, with no single point of trust and policy enforcement that no single party can override.
For existing WaaP users
Your wallet works on Sui now. Same login. Same security model. New chain. No new seed phrase, no new app. Just connect.
The ecosystem behind it
human.tech's infrastructure serves nearly 3 million verified users, with over 43 million credentials issued and more than $500 million in protected value. WaaP brings that foundation to Sui — ranked top 15 by TVL, top 8 by DEX volume.
"Sui developers can now offer seedless self-custody without taking on the risks of traditional wallet services," said Shady El Damaty, CEO of Holonym Foundation. "There's no tradeoff between user experience and true ownership. This is what embedded wallets should have been from the start."
