After presenting RoxxMarket at Solana Fall School: Demo Day, I stress-tested it and found settlement and refund issues.
They’re fixed. RoxxMarket is live on Devnet: roxxcli.com
Thanks @solana_devs for the chance to build and present.

Solana Fall School 2026 | Week 1, Day 3
What I learned:
- Votor replaces TowerBFT voting.
- Validators exchange votes directly, without vote transactions.
- Alpenglow targets ~150ms finality.
Thanks @TheWattenhofer for the Sep 4 session. Alpenglow is now live on mainnet.
Solana Fall School 2026 may be over, but there's still a lot to share !!
Starting tomorrow, I'll be sharing what I learned throughout Fall School, one day at a time.
I'll begin with Day 1.

What I learned:
- Rust ownership and borrowing.
- Anchor account constraints.
- PDA signing with seeds and bumps.
- Added a per-transaction withdrawal limit to a lamports vault.
- Tested below, at & above cap.

Resolver recovery improved.
Delayed markets recover.
Failures no longer block.
Diagnostics added.
Solana Fall School comes to an end! 🚀💜
Late night for some, early morning for others. 😂
Huge thanks to all the hosts and TAs for making it happen! 🫡
Glad to be part of Solana Fall School Demo Day 2 !!
Amazing to see what everyone’s building.
The future of Solana looks so bright, even Demo Day needed sunglasses😎🕶️

Why Rust, Anchor & PDAs?
RoxxMarket uses Rust + Anchor for market creation, predictions, verification, and settlement.
PDAs manage market state and control token vaults, keeping funds governed by program-defined rules.
Why PMT & AccessPass?
PMT is RoxxMarket's devnet - only prediction token, so users can participate without risking real funds.
Users can exchange Devnet SOL for PMT - and redeem PMT back into Devnet SOL.
The separate 1 Devnet SOL access payment activates AccessPass.
Today was Solana Fall School Demo Day!
I showcased RoxxMarket on @solana_devs - prediction markets with verifiable outcomes and on-chain settlement.
Project: roxxcli.com

Thanks @decentra1ized_ @joshyote @Javi_4B @aryansinghtwts!

Fable 5.1 is a massive upgrade, but the bigger story is the economics.
Cache reads are 75% cheaper than Fable 5, narrowing the real-world cost gap with GPT-5.6 Sol.
Costs drop ~25% for typical workloads and up to 45% for highly agentic ones.
The limits make more sense now.
