Why we raised prices (2026-05-23)
Earlier pricing ($29/year) was below the actual gas, RPC, and IPFS cost of serving a single Pro user. New pricing reflects the real cost of running infrastructure we intend to keep operational for the next decade, plus the work of standards authorship (ERC-8263) and multi-chain verification. Existing customers from the old pricing keep their original rate for 12 months from their first paid date.
Why Auto-Batch Saves up to 90%
100 individual anchors = 100 transactions = ~$50-500 in gas. 100 items in one batch = 1 transaction = ~$0.50-5 in gas. A 90%+ reduction by combining proofs into a Merkle tree while preserving individual verifiability.
