Methodology

How we source, verify, and present crypto data on howmanycoin.

Rate data sourcing

All conversion rates are sourced from CoinGecko, a widely-used cryptocurrency market data API. Rates are fetched every 60 seconds by a Cloudflare Worker deployed at the howmanycoin.com domain, then cached at the edge for 60 seconds to minimize API calls and ensure fast response times.

Crypto-to-crypto cross-rates

When converting between two cryptocurrencies (e.g. SOL to ETH), we compute a cross-rate using USD as the intermediary:

SOL/ETH = SOL/USD price ÷ ETH/USD price

This approach ensures accurate pricing even when a direct SOL/ETH trading pair is temporarily unavailable or illiquid.

Supply data

Token supply figures (total supply, circulating supply, max supply) are based on CoinGecko data and supplemented by official project documentation where available. Supply explainers are written to be accessible to non-technical readers and reviewed for accuracy before publication.

Editorial standards

All content on howmanycoin is written in plain English with no financial advice disclaimer. We aim to be informative, not promotional. Affiliate links are disclosed clearly: swap and exchange links may earn a commission at no extra cost to you.

Rate update frequency

Rates are refreshed every 60 seconds. The “last updated” timestamp shown on each converter page indicates when the current rate was fetched from CoinGecko.

If you spot an error in our rates or content, please reach out via the contact page. We aim to correct factual errors within 24 hours of being notified.
