# Bridged supply Methodology

## Overview

Bridged supply measures the value of stablecoins that are currently used outside of the chain where they were originally issued by the issuer. It is calculated by tracking the part of outstanding supply that is held in bridge contracts, and reflects user demand for the issuer’s stablecoins outside of the native chain.

## Data sources

- ERC-20 `Transfer` events and Starknet token transfer events from bridged asset contracts
- End-of-day price feeds for USD conversion
- Asset metadata for decimal precision and native chain identification

## Common calculation approaches

### Mint and burn tracking
Net flows are monitored by tracking mint and burn activity on destination chains. ERC-20 `Transfer` events and Starknet token transfer events are tracked from issuers such as Circle and Tether to determine the volume of assets utilized outside their native environments.

### Bridged asset supply aggregation
The outstanding supply of bridged versions of an asset is aggregated across non-native networks. For instance, the circulating supply of bridged assets is captured from issuers including Tether and Circle to quantify user demand across the multi-chain ecosystem.

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