Methodology

Crypto Yield Archive is a historical registry, not a live APY ranking, investment recommendation, or real-time dashboard.

Core principles

CYA records platform history, customer outcome, terms risk, failure chain, and evidence. Unknown values are preserved instead of forcing guesses.

v0 scope

v0 includes CeFi lending platforms, crypto interest accounts, centralized yield platforms, and borrowing/lending services.

Exchange Earn, DeFi lending protocols, yield aggregators, pool-level records, deployment-level records, real-time APY, and real-time TVL are deferred.

Counting unit

v0 counts platform entities. Products, pools, vaults, chain deployments, and individual claim classes are not separate platform records.

Record model

platform_entity

The platform or historically meaningful yield service.

platform_event

Timeline events such as withdrawal pauses, bankruptcy filings, restructuring, and distributions.

platform_evidence

Sources backing entity, event, outcome, terms-risk, or URL-history claims.

customer_outcome

What happened to user funds, including partial repayment, ongoing claims, or unknown outcomes.

Evidence and reliability

Preferred sources include official statements, court documents, bankruptcy documents, regulatory notices, archived pages, and reputable reporting.

Reliability is marked as high, medium, or low. Low-confidence records should not be treated as definitive.

URL handling

Original URLs are preserved as historical records. For ended or repurposed platforms, archived URLs should be preferred and unsafe domains should not be treated as normal outbound links.

Corrections

A good correction should include the platform name, CYA page URL, the field or claim that appears wrong, source links, and a short explanation.
