# Issuers and protocols: Your coin's footprint, read from the chain

> See where your stablecoin is natively issued and where bridged copies circulate, next to every other issuer, from reads your holders can check.

See where your stablecoin is natively issued and where only bridged copies circulate, next to every other issuer, from the same verified reads your holders, exchanges and regulators can check.

## One public, checkable view of your supply.

Transparency pages state total circulation. Holders and partners want to know where it is: which chains carry native supply, which carry bridged copies, and how that is changing.

Voltfin reads every deployment's totalSupply() at the day's last block and keeps the receipts, so your footprint is the same number for you, your exchanges and your regulator.

Build your own boards and dated reports on the same data in Studio, and share them with a link that opens each receipt.

## Workflows

### Footprint by chain

**The problem.** Total circulation hides where a coin lives. Native issuance and bridged copies carry different risks and different paths to redemption.

**With Voltfin.** Native supply of one coin on each covered chain, its 30-day change and its bridged copies apart, every day.

- **Native by chain.** Supply issued by the issuer's own contract on each chain.
- **Bridged apart.** Copies minted by bridges, listed on their own.
- **Daily history.** How the footprint moved, day by day, chain by chain.

### Share of the market

**The problem.** Exchanges, partners and investors compare issuers, and want figures they can check for themselves.

**With Voltfin.** Your share of USD supply against every other issuer, across chains, on the latest complete day.

- **Issuer league.** Every issuer's share of USD supply across chains.
- **One chain at a time.** A chain's own board shows each issuer's share there.
- **Checkable.** Every share opens the rows it was summed from.

### Contract by contract

**The problem.** On one chain a coin can have several contracts: native, bridged and wrapped. Adding them up counts supply twice.

**With Voltfin.** One chain from its total stablecoin supply down to each contract, with its issuer and whether it is native.

- **Every contract.** Each stablecoin contract on the chain, with its supply.
- **Native or bridged.** Which contracts the issuer redeems, and which it does not.
- **The chain's total.** Native supply summed once, with nothing double-counted.

## The rules behind it

Short summaries for orientation, not legal advice.

- **MiCA, Articles 43 and 56** (European Union): A token is classed as significant when it meets at least three criteria, among them more than 10 million holders, more than €5 billion issued, or more than 2.5 million transactions and €500 million a day. [Source](https://eur-lex.europa.eu/eli/reg/2023/1114/oj)
- **GENIUS Act** (United States): Issuers publish monthly reserve reports, examined by a registered public accounting firm, against the stablecoins they have outstanding. [Source](https://www.govinfo.gov/app/details/PLAW-119publ27)
