Data & Methods

Most crypto offer content on the internet is copied from other crypto offer content. Ours isn't. This page explains exactly how information gets onto this site — and what we refuse to publish.

Primary sources only

Every rate, bonus, restriction, and availability claim on this site comes from a primary source: the platform's own published terms, program agreements, help-center documentation, or the live product itself. We read the actual documents — the affiliate agreements, the restricted-jurisdiction lists, the bonus terms with their qualification requirements — not summaries of them, and not other websites' versions of them.

Verbatim capture and a dated archive

When we verify something, we capture it: exact language, saved with the date, preserved as dated documents in our research archive. When a platform later changes its terms — and they change constantly — we can show what the terms were and when they changed. Offer history is part of what makes offers legible.

Every number wears a date

Claims on this site carry a "Verified" date — the day we last confirmed that fact against its primary source. If a date looks stale, treat the claim accordingly and check the platform directly. We would rather show you an honest timestamp than pretend the internet stands still. A page may carry more than one date. When part of a page is re-checked — fees, say — that claim gets its own newer date while the rest keeps its last-confirmed one. And a Verified line sometimes names its scope ("against the published fee schedule," "structural facts") when we confirmed the shape of a thing rather than every number in it. More dates and narrower scopes are the method working, not the method slipping.

Re-verification

We re-verify on a schedule and on events: when we're about to act on information, when a platform announces changes, and on a recurring calendar for the offers and eligibility rules we track most closely. Pages get updated when the facts move, not on a content-marketing schedule. When something is mid-re-verification — a program changing its terms, a rollout we haven't finished checking — it appears in an "In flux" section rather than in the tables, and the tables say so. Publishing the gap is part of the method: a dataset that never has empty rows is a dataset that never checked anything.

What we refuse to do

We do not sell rankings. We do not accept payment for placement, inclusion, or favorable coverage. Commercial relationships (described in our Affiliate Disclosure) never determine what we say about a platform — including publishing the restrictions and downsides platforms would prefer omitted. Where the answer is "US users mostly can't use this," that is the answer we publish. Programs we participate in are verified the same way, against the same documents, as programs we don't.

Corrections

If we got something wrong, we want to know: hello@slotstacks.com. Verified corrections get fixed promptly, and material ones get noted on the affected page.
