Daily supply by issuer, chain and currency, with years of history and a receipt for every figure, so a chart in a paper or a supervisory note can be checked by its next reader.

## Reproducible by default.

Supervisors and researchers need stablecoin figures they can trace: where each number came from, and how to read it again.

Voltfin publishes versioned datasets: each figure names its dataset version and row, and each row its contract and block. A citation keeps working after the data moves on.

Dated monthly reports explain the change by chain and by coin, in prose, with every figure cited.

## Workflows

### Cite with a receipt

**The problem.** A quoted figure is only as good as its source, and a reader has to be able to find that source.

**With Voltfin.** Every figure opens its receipt, which names the dataset version, the row, the contract and the block, so a citation points at the exact read.

- **Versioned.** A figure names the dataset version it came from.
- **Pinned.** Each row names its contract and block.
- **Linkable.** A board's link keeps its filters, so readers open what you saw.

### Cross-check reported supply

**The problem.** Issuers report circulation on their own pages. Checking it means reading every chain they are deployed on.

**With Voltfin.** Supply by token, chain and day, from contract state, to set beside what issuers report.

- **Every deployment.** Each covered chain's contract, read at the day's last block.
- **Native only.** Bridged copies apart, so totals are not inflated.
- **Downloadable.** CSV with a receipt on every row.

### Dollar and euro side by side

**The problem.** Euro stablecoins are a small, fast-moving market that dollar-centric figures hide.

**With Voltfin.** The same reads for both currencies, so a euro coin's footprint compares directly with a dollar one.

- **Per coin.** A coin's native supply on each chain.
- **Per currency.** USD and EUR totals from the same method.
- **History.** Daily, as far back as the data goes.
