@sealedmind/sdk

TypeScript / JavaScript SDK for SealedMind — encrypted, capability-gated AI memory on 0G.

npm install @sealedmind/sdk

Quickstart

Get an API key in two clicks at https://sealedmind.vercel.app/developer (connect wallet → SIWE sign → copy sm_* key).

import { SealedMind } from "@sealedmind/sdk";

const client = new SealedMind({
  apiUrl: "https://sealedmind-backend-production.up.railway.app",
  apiKey: "sm_...",
});

// Create a Mind (mints an iNFT for the wallet bound to the key)
const { mind } = await client.createMind("my-agent");

// Store a memory — encrypted before upload
await client.remember(mind.id, {
  content: "User prefers vegetarian meals",
  shard: "preferences",
});

// Recall — TEE-attested response from Qwen 2.5 7B in Intel TDX
const result = await client.recall(mind.id, {
  query: "What does the user prefer to eat?",
});
console.log(result.answer);
console.log("attested in:", result.attestation.enclave);

Capability sharing across agents

// Patient grants doctor's agent read-only access to "fitness" shard for 30 days
const grant = await client.grantCapability(mind.id, {
  grantee: "0x21fc...",
  shard: "fitness",
  readOnly: true,
  expiry: Math.floor(Date.now() / 1000) + 30 * 24 * 3600,
});

// ...later, patient revokes
await client.revokeCapability(mind.id, grant.capId);

Capabilities are real on-chain transactions on the SealedMind CapabilityRegistry contract on 0G mainnet. Revocation is enforced by verifyCapability returning false on the next read.

What this gives your project

• Memories encrypted client-side with AES-256-GCM under a key bound to the user's wallet. The backend never sees plaintext.
• On-chain capability primitive for sharing memory between agents — revocable any time, no caches to invalidate.
• TEE-attested inference (Qwen 2.5 7B in Intel TDX) for sensitive reads — every response carries a chatId you can re-verify.
• ERC-7857 iNFT ownership — your Mind is a tradeable asset, not vendor-locked data.
