Mobile SDK
iOS and Android SDKs for integrating TimeProof timestamping into mobile apps.
TimeProof’s core platform handles blockchain timestamping for any file type. The Mobile SDK adds specialized workflows, optimized interfaces, and domain-specific features for developers who want to integrate timestamping into their tools and pipelines.
What This Module Adds
Specialized Workflows
The Mobile SDK provides pre-configured workflows designed for its target audience. Instead of the generic file-upload interface, users get a streamlined experience optimized for their specific use case.
Domain-Specific Features
Each module includes features that make sense for its audience:
- API endpoints tailored to developer workflows
- SDK libraries for popular languages
- CI/CD pipeline integrations
- Webhook support for automated notifications
Integration Points
The Mobile SDK integrates with:
- The core TimeProof timestamping engine
- The Legal-Grade evidence package system
- The verification and certificate generation pipeline
- The COP (Cryptographic Ownership Proof) system (when available)
How It Works
The technical foundation is the same as core TimeProof:
When you use core TimeProof timestamping, TimeProof uses client-side file hashing (SHA-256). That 64-character value is the unique fingerprint for the exact version you selected, and if even one byte changes, the hash changes too. Your file never leaves your device.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. The blockchain records the hash, timestamp, and transaction ID permanently, so the same proof model remains independently verifiable on Polygonscan.
The specialized workflow in the Mobile SDK changes the interface, not the underlying cryptographic guarantees.
The Mobile SDK adds a layer of convenience and optimization on top of this foundation, without changing the underlying cryptographic guarantees.
What You Receive
Every TimeProof timestamp for core timestamping today includes:
- PDF certificate - a readable proof document available now while the specialized module itself is still on the roadmap.
- Polygonscan link - direct public verification of the core record even before module-specific UX exists.
Verified instant timestamps also include: 3. Verified identity badge - the certificate shows the timestamp was created by a verified account, which is useful when a verified operator or team identity needs to be attached to the record.
With the Legal-Grade upgrade, you also receive the core evidence-package components documented by TimeProof: PDF, JSON, JWS identity attestation, and a ZIP bundle.
- Courtroom-Ready PDF - a presentation-ready evidence certificate if a module-related workflow later feeds a dispute, audit, or compliance process.
- JSON Metadata - machine-readable timestamp data for technical teams, audit trails, or structured evidence review.
- Identity Attestation (JWS) - a signed proof that ties the timestamp to a verified identity and can be verified through /.well-known/jwks.json.
- Complete Evidence ZIP - one bundle containing the Courtroom-Ready PDF, JSON Metadata, Identity Attestation (JWS), and supporting proof materials so teams can hand over a complete package without waiting for the specialized module to launch.
Module-specific outputs may include additional reports, dashboards, or integrations depending on the feature set.
Current Status
Core TimeProof timestamping is live and available now. The Mobile SDK is on the roadmap for future release.
You can start using core timestamping features today. When the Mobile SDK launches, it will integrate with your existing timestamps and records.
Start Today
TimeProof uses one unified credit balance for the live core platform, so you can start building protected records now even before the Mobile SDK ships.
- Scheduled timestamps: 1 credit per file - available to everyone, with proof available within 6 hours.
- Instant timestamps: 2 credits per file - available to verified subscribers, anchored in about 2 seconds.
- Legal-Grade: Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.
One-time packs start at $15 for 100 credits. Verified monthly plans start at $19/month and include identity verification for instant timestamps and Legal-Grade.
That lets teams adopt the core proof workflow first, then layer the specialized Mobile SDK experience on top when it becomes available.
Begin building your protected file history now with core timestamping. The Mobile SDK will add specialized capabilities when it launches.
