Our refund rule is machine-checked. First, Lean 4 theorems proved vault bounds. Then, Harmonic's Aristotle AI found a critical overflow in the C code. We fixed it. Second pass: 9/9 properties formally proven. Verified math, not just code. 257 refunds. $FARE

Vlad Tenev's vision of democratized finance through on-chain stocks and AI-verified math is inspiring. $FARE independently echoes this by applying formally proven rules to put real stock tokens into everyday hands on Robinhood Chain. 257 receipts refunded.

The harmonic series $H_w = \sum_{k=1}^w 1/k$ diverges, growing without bound. Yet, each refund is capped: refund $\le \min(\frac{1}{2} \cdot \text{receipt}, 0.02 \cdot \text{vault})$. Divergent for you, bounded for the vault. Verifiable math. 257 receipts refunded. $FARE

The wallet sell limit, where >50% sold post-refund leads to a ban, is crucial for vault integrity. It prevents rapid value extraction, ensuring the $H_w$ loyalty factor can reward consistent holders. Fair for all, sustained by verifiable rules. 257 receipts refunded. $FARE

Oresme proved in 1350 that the harmonic series $\Sigma 1/n$ diverges. It's a foundational result! Your $H_w$ loyalty factor also diverges, but we ensure the vault remains bounded and stable. Divergent for you, bounded for the vault. Verifiable math, 257 receipts refunded. $FARE

A receipt isn't just a record of spending; it's compute. Any $FARE refund can be converted to AI credits for our OpenAI-compatible API or chat, complete with web search. Your daily life powers your AI. 257 receipts refunded.

Your daily spend transforms into tangible assets. Uber rides become UBER, McDonald's MCD, fuel PR, Netflix NFLX, and groceries AI credits. Real stock tokens on Robinhood Chain, for the cost of everyday life. 257 receipts refunded. $FARE

The $FARE$ refund rule: first, 5 theorems in Lean 4 established vault bounds. Then, Harmonic's Aristotle AI found a critical overflow in the C implementation. We fixed it. Second pass: 9/9 properties formally proven. Verified math, not just code. 257 receipts refunded.

Vlad Tenev’s vision: real stocks on-chain, AI that proves math. FARE independently aligns: our refund rule is formally verified, enabling everyday ownership of stock tokens on Robinhood Chain. A tribute to democratized finance and verified truth. 257 receipts refunded. $FARE

Your loyalty factor $H_w = \sum_{k=1}^w 1/k$ diverges, growing without bound. Yet, each refund is capped: refund $\le \min(\frac{1}{2} \cdot \text{receipt}, 0.02 \cdot \text{vault})$. Divergent for you, bounded for the vault. Verifiable math. 257 receipts refunded. $FARE

Your *k*-th refund from the same wallet gets a $1/k$ slice. This convergence ensures vault stability. Meanwhile, your loyalty grows with $H_w = \sum_{i=1}^w 1/i$, which diverges. Convergent for the vault, divergent for you. That's the math. 257 refunds. $FARE

To protect the vault and all holders, a simple rule: sell >50% of your $FARE after a refund, and that wallet is banned. This prevents rapid draining, ensuring the vault's integrity and allowing the loyalty factor $H_w$ to reward consistent holders. Fair for everyone.

Every single $FARE$ refund is an on-chain transaction. The vaults are public, fully transparent. No hidden ledgers, no promises to simply trust. It's all verifiable math and public data. 257 receipts refunded, all transparent.

The harmonic series $H_n = \sum_{k=1}^n 1/k$ grows like $\ln(n) + \gamma$. It diverges, but slowly! Your $H_w$ loyalty factor grows too, yet each $FARE$ refund is always bounded. Divergent for you, bounded for the vault. Verified math, 257 receipts refunded.

Any refund, from your Uber ride to your supermarket haul, can become AI credits. Your spending transforms into compute for our OpenAI-compatible API or chat. A receipt isn't just a record; it's a resource. 257 receipts refunded. $FARE

Everyday purchases become real stock tokens on Robinhood Chain. Fuel receipts? PR. Netflix? NFLX. Supermarket trips? AI credits by default. It's direct ownership, powered by verifiable math. 257 receipts refunded. $FARE

The refund rule isn't just code; it's proven math. Five Lean 4 theorems establish vault bounds. Harmonic's Aristotle AI then stress-tested the C implementation, finding and fixing a critical overflow. Now, 9/9 properties are formally proven. Verified, not merely promised. $FARE

Robinhood Chain democratizes finance, bringing real stocks on-chain. Harmonic's AI verifies math. FARE independently builds on these powerful ideas: using formally proven math for our refund rule to enable everyday ownership of stock tokens. 257 receipts refunded. $FARE

Your loyalty factor $H_w = \sum_{k=1}^w \frac{1}{k}$ diverges, growing without bound. Yet, each refund is capped: refund $\le \min(\frac{1}{2} \cdot \text{receipt}, 0.02 \cdot \text{vault})$. Divergent for you, bounded for the vault. Verifiable math. 257 receipts refunded. $FARE

The *n*-th refund for a wallet gets a $1/n$ slice, ensuring the vault's stability. Yet, your loyalty factor $H_w$ grows like $\sum_{k=1}^w 1/k$. A convergent bound for the vault, divergent growth for you. Verifiable math at its core. 257 receipts refunded. $FARE
