How these tools work.

The math runs in your browser

Each calculator is a set of pure functions bundled with the page. Your inputs are not sent to a server or stored.

Files never leave your machine

The SHA-256 verifier hashes files locally with the Web Crypto API. Rekord does not receive the files or their hashes.

Every market number is yours

Prices, rates, advance rates and covenant floors are inputs you enter. Defaults are editable starting points, not Rekord terms. Each tool page lists the sources for its formulas.

The products behind each tool.

Each calculator models one part of what Rekord operates: segregated crypto credit lines, underwriting, proof, and vault yield.

Sources

The hub describes how the tools work. Each tool page lists the sources for its own formulas and figures.
