The Algorand Foundation has introduced LiquidAuth, an open-source solution designed to eliminate one of the most pressing security flaws in the crypto industry: centralized wallet communication. By enabling decentralized, authenticated peer-to-peer interactions between wallets and applications, LiquidAuth sets a new standard for secure and private digital identity across both web3 and traditional web2 environments.
This innovation directly addresses the growing concern around reliance on centralized infrastructure—particularly WalletConnect, which currently serves as the dominant protocol for wallet-to-dApp connectivity. While widely adopted, WalletConnect operates as a permissioned, centralized service, creating a single point of failure that could jeopardize millions of users if compromised.

The Problem with Centralized Authentication
In today’s digital landscape, secure authentication is non-negotiable. Yet, despite blockchain’s promise of decentralization, many web3 applications still depend on third-party services to facilitate basic user logins and communications. WalletConnect, though instrumental in onboarding users to dApps, lacks transparency and openness—its codebase is not fully public, and developers must seek approval to build on or modify it.
More critically:
- No authenticated communication: WalletConnect does not verify the authenticity of messages exchanged between wallets and apps, leaving users vulnerable to phishing and man-in-the-middle attacks.
- Censorship risks: The provider can block IP addresses or entire blockchains, potentially cutting off access for users or projects without recourse.
- Single point of failure: A breach or outage at WalletConnect could disrupt connectivity for countless wallets and decentralized applications globally.
These vulnerabilities undermine the core principles of decentralization, privacy, and user sovereignty that define web3.
Introducing LiquidAuth: A Decentralized Alternative
LiquidAuth is engineered to replace centralized intermediaries with a trustless, open standard. Built using established protocols like FIDO2 and Passkeys, it enables secure, verifiable communication between digital wallets and services—without relying on any central server.
Key features include:
- Chain-agnostic design: Works across any blockchain or web2 platform, supporting seamless integration regardless of underlying technology.
- Open-source licensing (AGPL): Freely available for developers to use, audit, modify, and extend—ensuring transparency and community-driven improvement.
- No data storage: LiquidAuth does not collect or store user information, preserving privacy by design.
- Interoperability: Compatible with existing web3 tools and identity frameworks, making adoption easier for developers and users alike.
By removing centralized relays, LiquidAuth drastically reduces the attack surface for malicious actors while reinforcing user control over their digital identities.
Why Open Standards Matter for Web3 Security
Decentralization isn’t just about distributed ledgers—it extends to every layer of the tech stack. When critical components like authentication rely on closed systems, they reintroduce the very risks blockchain was meant to eliminate.
John Woods, CTO of the Algorand Foundation, emphasized this point:
"For decentralized models to become the norm, the industry must insist on higher standards for the security and openness of critical infrastructure. We developed LiquidAuth to bring these standards to the ecosystem."
He added:
"An open and decentralized standard like LiquidAuth will improve security across web2 and web3. It reduces reliance on third parties for login processes—such as email or social accounts—and further decentralizes the communications layer between applications, users, and services."

Broader Implications Beyond Crypto
Although developed in response to WalletConnect’s limitations, LiquidAuth’s utility extends far beyond cryptocurrency. Any system requiring secure user authentication—online banking, healthcare portals, government services—can benefit from its decentralized architecture.
Imagine logging into your bank using a self-sovereign identity verified through cryptographic proofs, without handing over personal data to a middleman. Or accessing medical records via a passkey-based system that never stores your credentials on a server. These are real-world applications enabled by LiquidAuth’s foundational design.
Moreover, by promoting open standards, Algorand supports broader initiatives like the Open Wallet Foundation and the recently co-launched DeRec Alliance, which aims to standardize secure digital asset recovery methods.
Frequently Asked Questions (FAQ)
Q: What makes LiquidAuth more secure than WalletConnect?
A: Unlike WalletConnect, LiquidAuth uses end-to-end authenticated communication based on open standards like FIDO2. It eliminates centralized message relays and doesn’t store user data, significantly reducing exposure to breaches and surveillance.
Q: Can LiquidAuth be used outside of web3?
A: Yes. Its chain-agnostic nature allows deployment in any web2 application requiring secure authentication—such as passwordless logins for enterprise software or identity verification platforms.
Q: Is LiquidAuth free to use?
A: Absolutely. It’s released under the AGPL license, making it free to use, modify, and distribute—encouraging widespread adoption and community contributions.
Q: Does LiquidAuth require special hardware?
A: No. It works with existing devices that support modern authentication methods like biometrics or hardware security keys (e.g., YubiKey), leveraging widely available technologies.
Q: How does LiquidAuth prevent censorship?
A: Since there’s no central authority controlling access, no entity can block specific users, blockchains, or applications from using the protocol—ensuring equitable access.
Q: Who can integrate LiquidAuth into their platform?
A: Developers, wallet providers, dApp creators, and even traditional tech companies can integrate LiquidAuth into their systems. Comprehensive documentation and SDKs are available to streamline implementation.
