Market-Data Note

Wallet fiat values are normally supplied by third-party market-data providers. Chainlink and Onyx price endpoints provide transparent reference data, but CoinGecko, CoinMarketCap, and wallets may require tracked markets, liquidity, and review before displaying a fiat value.

Public tracked market URLs will be added here once final venue links are available. This page does not claim that EUPY or EUPX is already listed by CoinGecko, CoinMarketCap, or any wallet provider.
