Publish Certificates of Analysis (COAs) anchored on Coinbase's Base Layer-2 ledger. Build trust that bypasses our hosting entirely, giving customers lifetime verification power.
Your Certificate PDFs never leave your WordPress server. We compute a secure 32-byte SHA-256 hash locally. Only this anonymous cryptographic fingerprint is anchored on the ledger.
No Web3 wallets to manage, no Ethereum accounts to secure, and no network gas fees to coordinate. The Oracle manages all Base ledger gas payments automatically behind a standard SaaS key.
Your verification logic queries the public Base L2 blockchain directly via public JSON-RPC nodes. Your COAs remain authentic and fully verifiable by regulators and litigators even if we go offline.
Most systems require you to query their API forever to verify document history. BatchLedger anchors proof on Base, enabling direct browser-to-blockchain validation.
The WordPress plugin computes the SHA-256 fingerprint locally of the COA PDF upon upload. The raw file stays completely private on your host.
The server POSTs the 32-byte hash to the secure BatchLedger Oracle. The API validates your Pro key, funds network gas, and signs the transaction.
The transaction is submitted to the BatchLedgerNotary contract on Base, anchoring the hash, timestamp, and signer address immutably.
The user downloads the PDF and checks Base L2 via direct JSON-RPC node calls. The authenticity check bypasses BatchLedger servers entirely.
Upstream labs carry severe regulatory and reputation risks if vendors modify testing reports before posting. By pushing Certificates of Analysis into a decentralized trust ledger, labs receive:
Provide clear proof that "this exact PDF report was issued by this specific lab at this exact second."
Replace complex email chains and manual database checks with a single on-chain timestamp, instantly audit-ready for the FDA or state departments.
Coming on the product roadmap: co-branded verification badges that labs can show on their own sites, proving direct link history to customers.
While the BatchLedger WordPress plugin is the native WooCommerce implementation available today, our cryptographic backend is fully decoupled. The core technology allows for custom integrations with Shopify, Magento, and proprietary ERPs.
Labs and enterprise merchants can build trust indicators that perform direct blockchain lookups without locking themselves into a single content management system.
We don't sell paper promises. The smart contract is live and accepting cryptographic hashes on the Base Sepolia testnet right now.
