Methodology & neutrality

• Neutral by design. No provider can pay to change its data, its ranking, or the table's default order (alphabetical / user-sorted).
• Sources only. Every field comes from a public first-party page (docs, pricing) or a cited secondary source; anything we can't verify is marked unknown.
• Dated. Each entry carries a last_checked date; we re-check regularly and log changes in the newsletter.
• Sponsorship is labeled. Featured listings are visually marked 'Sponsored' and never alter the comparison data.
• Corrections. Providers may submit corrections with a source URL; we verify before publishing.
• Fields. Custody = who holds/controls keys or credentials. Limits enforced = where spend caps live (onchain contract, provider policy engine/TEE, or client SDK — client-side caps are weakest).
