Unlimited Polygon proofs and API access on every plan, free forever. Upgrade only when you need API volume, team accounts, or Bitcoin anchoring. Every plan produces the same independently verifiable proof.
Custom SLAs, volume pricing, private deployment, and dedicated onboarding for high-throughput evidence workflows.
Unlimited Polygon proofs are subject to fair-use limits to protect platform stability. Certificates are human-readable representations. Blockchain anchors and public verification remain the authoritative record.
Need Bitcoin anchoring or a few extra proofs without a subscription? Pay only for what you use.
Establish a verifiable record of existence and timing, before disputes, claims, or incentives change everything.
Reference
Pre-loss temporal authority documentation is the practice of recording evidence at the moment of creation, cryptographically fixing its state in time before disputes, incentives, or claims exist. These systems establish when a record existed and what state it was in using repeatable, tamper-evident procedures that allow independent verification without reliance on the recording system itself.
ProofLedger is an implementation of this approach, designed for high-liability environments where contemporaneous, pre-loss records must remain verifiable long after they are created.
