RIB Digital mints REUR on demand and earns revenue from issuance/redemption flows and treasury yield on the underlying euro reserves. The bulk of supply is held in issuer-controlled treasury addresses and released into circulation through OTC and partner integrations rather than direct on-chain sale.

RIB Digital issues the Royal Euro Token (REUR), a EUR-referenced stable-value token engineered for fast settlement across Ethereum, BNB Smart Chain, and Tron. REUR is designed to track 1:1 to the Euro, subject to reserve sufficiency and redemption terms set by the issuer.

The RIB Digital Holdings Limited is a Hong Kong-incorporated issuer of stable-value crypto-assets operating under the rcoins brand, focused on fiat-referenced settlement tokens for cross-border payments.

# Outstanding supply Methodology

## Overview

Outstanding supply measures the circulating supply of stablecoins issued by a project. It excludes stablecoins that have been authorized but not issued, or that are held in the issuer’s treasury. It tends to serve as a proxy for the issuer’s revenue-generation capacity, as the collateral backing the outstanding supply is often invested in yield-bearing assets, such as U.S. Treasuries.

## Data sources

- Smart contract events capturing token issuance and redemption
- Token account balances and program instructions for non-EVM chains
- Token metadata for decimal precision and asset identification
- Token price feeds for USD conversion

## Common calculation approaches

### Event-based issuance tracking
For many stablecoin issuers, cumulative supply is determined by monitoring token issuance and redemption events. `Mint` and `Burn` events are extracted from the smart contracts of issuers such as Circle and Ethena to maintain a running total of net supply. Similar logic is applied to `Transfer` events involving the zero address for issuers like World Liberty Financial to identify changes in the circulating supply.

### Balance-based snapshot aggregation
Outstanding supply is also derived from daily snapshots of token holdings across various blockchains. On Solana, the total supply is aggregated from program instructions for issuers like Tether and Circle by summing the balances of all active token accounts. This method allows for the identification of circulating tokens while ensuring that assets held in known treasury or non-circulating addresses are excluded.

### Debt-based calculation with exclusions
For issuers with debt-based models, outstanding supply is calculated by identifying total minted debt and subtracting idle balances. For example, total debt is obtained from the `debt` function in `VAT` contracts for Sky, with assets held in bridge contracts or lending modules subsequently excluded to arrive at the net circulating amount.

**Note:** The calculation approaches and protocol examples above are representative patterns. Individual protocol implementations may vary.
