How this sample allocation works

Example parameters: 1,000 USDC budget → 700 public subsidy + 300 holder credits. Assumed effective holdings: 100 / 10,000 → 1% → 3 in personal usage credits, reserved from the holder pool. The other 297 remains unallocated. Each completed example moves a reserved amount into consumed usage; it does not deduct the holder budget twice.

Examples use 20% public coverage, capped by the public pool, then available personal credits. Remaining user cost is calculated only; no payment is collected. Credits are usage allowances, distinct from VELTAN tokens, model tokens and USDC funds.

Real wallet reading: no wallet is connected in this walkthrough. Real service balance: no hosted model balance is loaded. Sample inputs do not create real claim eligibility. Explore different scenario parameters ↗

Sample Output / PREVIEW

claude-opus-4-6 / Summarize a budget

1. The example allocates 700 USDC to public subsidies.
2. It reserves 300 USDC for holder compute credits.
3. Credits cover model usage; they are not cash or token balances.
Walkthrough controls and storage rules

All tasks use the same local example allocation. Refresh preserves completed records; changing model or task preserves balances and selects a new fixed fixture. Reset restores the default allocation and clears these receipts. Earlier demo account storage is separate and is never read or overwritten here.
