WOYALE.How we research
Primary sources first, a date on everything, and no claims we can't point to.
Sources we trust most
- The rule itself. State statutes, regulator websites and license lists, the US Code, IRS publications and forms, and court opinions.
- Official technical docs. Standards such as RFC 2104 (HMAC) and NIST FIPS 180-4 (SHA-256), and the documentation published by blockchains and stablecoin issuers.
- Company help centers for exchange-specific facts such as supported networks, limits and fees, which change often.
Gambling news sites and affiliate review sites are useful for spotting that something has changed. We don't cite them as proof. If we can't confirm a fact on a primary source, we leave it out or say plainly that it's unclear.
State pages
Each state page shows its status, the regulator, the main statute and the month it was checked. "Licensed online betting" means a state regulator licenses mobile sportsbooks that take bets statewide. "In person only" covers retail, tribal and on-premises mobile betting. "No legal sportsbooks" means the state licenses neither.
Worked examples
Numbers in examples are worked out, not estimated. Hash and roll examples are computed with the same formula our verifier uses. Fee examples are labelled as illustrations, because network and exchange fees move daily.
Independence
We take no money from sportsbooks, casinos or exchanges and run no affiliate links. No company reviews our pages before they go live.
Corrections
Law and tax rules change. When we find something out of date, we fix the page and update its checked date.
