Real Estate & As-Built Plans

A building's life-long digital twin.

The Problem

Buildings last centuries, but blueprints and 'as-built' architectural documents are easily lost as developer domains expire.

Why The Eternal Tier Responds Intentionally

A plaque in the utility room can keep a recoverable pointer to the structure's technical specs.

Cryptographic AnchoringUnlike the Free/Basic hosted tier, the paid Eternal tier writes an encrypted routing payload to Base L2. Eternal QR derives and exports a per-user recovery key so the last anchored destination can be decrypted without the Eternal QR servers. Basic operates on traditional infrastructure and does not include blockchain anchoring.

Real-world Example

A 2026 residential build is handed over with a permanent QR for its electrical and plumbing schematics.

Future-proof your real estate & as-built plans

Stop leaving a critical digital legacy entirely in the hands of generic SaaS tools. Add Base anchoring and recovery-key export with the paid Eternal tier.
