For buyers

Retire with confidence.

CRIOS is built for buyers who can't afford to be wrong. Every token traces to a verified source. Every retirement generates a public, downloadable certificate.

Verified by default

Every token carries a tier badge and links to its source measurement. No bridged junk credits ever enter our supply.

Audit-ready records

Retirement certificates are timestamped, signed, and verifiable at a public URL. Drop them straight into your annual sustainability report.

Programmatic settlement

API access for enterprise buyers (Q3 2026). Programmatic retirement, custodial accounts, transparent fees.
