Escrow Session Vault for Micro-Billing P2P Video Streaming | (iOS Android)

In 2026Q1, we built a chain-agnostic micro-billing P2P video streaming Android app that was funded by xGov retroactively (xGov Proposal). This quarter, we innovated further by adding two key improvements on top of that for a new deliverable milestone:

  1. Added iOS support (for liquid stream feature)
  2. Transitioned the micro-billing session vault for Android & iOS to an Algorand escrow smart contract (that supports Algo25, HD, PQ Falcon24 lsig accounts). This smart contract is inspired by session vault draft spec. It has been designed to be generic and the smart contract can be used by any other project (e.g. not limited to video streaming context).

Here is a PR link to a video showing off both features working (Video Demonstration). You can see micro-billing (escrow session vault style) video streaming for a Falcon (lsig) account working on iOS and Android over liquid auth. Any questions can be directed to forum link.

We are requesting 88,888 ALGO in retroactive funding for three months of high-intensity development (April - June 2026). This work was successfully delivered over five iterative releases (v3.202602.4 through v3.202602.8) in alignment with our 2026Q2 roadmap.

Michael T Chuang currently serves as a member of xGov Council and will abstain from voting on this proposal within xGov Council to prevent conflict of interest.

Additional Info The requested funding will be reinvested in future quarters to improve Liquid Stream use case further. We will also be updating the escrow smart contract to support PQ Falcon native accounts when it's released to testnet (should be in the near future). Investigating if using a lsig approach is cheaper to operate for session vault is also on the roadmap this summer.
