NEXUSHIELD turns ephemeral transactions, invoices, and AI decisions into permanent, verifiable evidence — without ever touching customer PII. When your ERP is gone, your proof isn't.
Regulators, auditors, and courts increasingly ask a question your stack cannot answer: "Prove this event happened, exactly as you say, at the time you say."
Every migration, acquisition, or vendor switch severs evidence trails. The transaction is gone the moment the database is retired.
When an agent approves, denies, or acts autonomously, there is no independent proof of what it saw, when, or why.
Anyone with database access can rewrite history. A CSV export is not evidence — it's a claim without a witness.
Every event that enters NEXUSHIELD follows the same choreography — from raw signal to on-chain evidence in seconds.
REST, webhook, or SDK. Square, QuickBooks, Global Payments, Wave, Shopify, or your own.
Field-normalized SHA-256 over canonical JSON. Same event → same hash. Never PII.
Aggregated into a Merkle tree so a single on-chain write anchors thousands of individual records.
The Merkle root is committed to Monad. Immutable, timestamped, publicly verifiable.
GET /verify/{id} returns canonical JSON, Merkle proof, and the on-chain tx anyone can inspect.
Ask a question about your business. Get an answer with a source. Every claim carries a citation. Every citation is a verifiable anchor.
A screenshot can be edited. A PDF can be forged. A database can be rewritten. An anchor cannot — because it was witnessed by every node in the chain the moment it was written.
Every layer is independently deployable, independently auditable, and independently replaceable. The proof chain survives all three.
Adapters for Square, QuickBooks, Global Payments, Wave, Shopify, Stripe, and custom webhooks. Signature-verified at the edge.
Canonicalization, Merkle batching, chain anchoring, proof persistence. Runs behind FIFO queues so ordering is preserved even under burst load.
Public REST endpoint and hosted verifier page. Any auditor, regulator, or counterparty can validate a claim without an account.
Each module solves a specific evidence problem. All share the same proof chain, so cross-module reconciliation is automatic.
The core write path. Any event in — a permanent, verifiable anchor out. The foundation every other module builds on.
Public verification for auditors, regulators, and counterparties. No account required — the proof speaks for itself.
Ask anything about your anchored evidence. Every answer cites the anchors that prove it.
Cross-vendor reconciliation across payment processors, ERPs, and banks — driven by shared anchor IDs.
Long-horizon evidence retention. When your ERP is retired, your proofs still resolve. Ten-year guarantee.
AI-agent decision attestation — every automated action carries a receipt anchored the moment it fires.
If your name goes on the report, NEXUSHIELD is the layer beneath your signature.
Every line in the ledger resolves to an on-chain anchor. Audit prep drops from weeks to hours.
Produce evidence a regulator can independently verify — not just a screenshot you promise is accurate.
Sample every transaction, not just a slice. Merkle proofs make full-population testing computationally trivial.
Retire an ERP without losing history. Anchors are portable, permanent, and vendor-independent.
Every autonomous decision leaves a receipt. When the agent acts, the proof is anchored before the side-effect fires.
Independently verify claim details without depending on the counterparty's word or their infrastructure.
Three real Square transactions anchored to Monad. Click any Verify link — no login, no account, just proof.
Free sandbox. No credit card. Real Monad testnet anchors. Bring your webhook, ship a proof, verify it yourself.
