(Android/iOS) Liquid Auth for Algorand Post-Quantum Accounts

1. The Request
   Here is a link to the repo of our work (app side) - algokit-walletsdk-kmp
   Here is a link to the repo of our work (liquid auth service) - liquid-auth

Demo Apps:
Android - Play Store
iOS - TestFlight

We’re asking for 100,000 ALGO in retroactive funding to cover two months of intense, focused development (Nov 1 to Dec 31, 2025)…which aligns with our 2025Q4 roadmap and releases v3.202504.2, v3.202504.3, v3.202504.4, v3.202504.5, v3.202504.6, v3.202601.0, and v3.202601.1.

2. What We Delivered (Results)
   In 2025Q3, we released a playground wallet to the (iOS) App Store and (Android) Play Store supporting Post-Quantum (PQ) accounts. Our 2025Q4 goal was to build on this foundation, enabling PQ account support within Liquid Auth (Algorand’s P2P WalletConnect competitor) for use across ecosystem dApps.

Here’s what’s ready to use after our 2025Q4 work:

• Mobile PQ Tooling: We updated mobile PQ tooling to support 24 BIP39 words.
• Wallet SDK: We added support in our wallet-sdk-core and wallet-sdk-ui libraries for localization, passkeys, liquid auth, and watch accounts. The updated xcframeworks and aar binaries are on maven central.
• Demo Apps: Playground Wallets (Android/iOS) are able to scan Liquid Auth QR codes and connect with Liquid Auth service
• Liquid Auth Service - Liquid Auth Service (testnet fork that supports PQ accounts)

3. Liquid Auth & Post-Quantum Accounts (Why Now?)
   PQ accounts deliver immediate technical wins for the network: superior secret key protection (compared to ECC), a 4x boost to TPS, and a higher minimum fee of 0.004A (compared to 0.001A)…which is all beneficial for long-term chain sustainability.

4. Deliverable Wins

• We extended this work from Pera (Introducing Liquid Auth in Pera) so now you can also create passkeys for github/gmail with a Falcon24 PQ account in our wallet.
• We extended this work from Algorand Foundation (Liquid Auth) so now users can send test dApp transactions and sign from a mobile wallet’s Falcon24 PQ account.

The features we built let community early adopters play with Liquid Auth using PQ accounts. Now it’s just a matter of integrating into use-wallet next and convincing ecosystem dApps to use this instead of walletconnect.

5. Our Future Vision (Where we’re trying to go)
   The requested funding will be reinvested in future quarters to launch new projects/features that specifically attract and make life easier for Algorand mobile developers. For 2026Q1, we will try to add back Liquid Auth option to use-wallet project and integrate with at least one dApp in mainnet (e.g xGov site). Soon you’ll be able to use PQ accounts on algorand dApps much easier!

Additional Info
We added localization support to our wallet in 2025Q4 as well - Hindi (for Algorand India Summit) and Italian (Algorand has a rich Italian history due to Silvio). You can use our new screenshot test tool to see all the new flows - Screenshot Test Tool

Adoption Metrics

• 100+ unique repo cloners, 600+ repo clones
