Signed receipts for every AI agent action.

What Record does

Every consequential action your AI agent takes — API calls, database writes, financial transactions, customer communications — gets wrapped in a cryptographically signed receipt.

• Ed25519 signature breaks if the record is altered
• Hash chain links every receipt to the previous one
• Merkle anchoring commits batches to a public root
• Anyone can verify offline — no Aegisys account needed

See it in code

import { createWitness } from "@aegisys/record";

const witness = createWitness({ tenantId: "my-app" });

const receipt = await witness.wrap(
  { action: "stripe.charge", amount: 2000 },
  async () => stripe.charges.create({ amount: 2000 })
);

// receipt.seal    → Ed25519 signature
// receipt.chain   → hash-linked to previous action
// receipt.verify() → anyone can check, offline
