Most digital identity systems don't verify identity — they approximate it. PTERI replaces guesswork with cryptographic proof.
Device → Cryptographic Proof → Verifiable Action
Interactive Demo
Experience the self-custodial web wallet interface used to authorize requests and manage decentralized identity.
The Root Problem
Identity failures are structural. As AI and automation accelerate, fragile systems fail more often — and cost more.
Core Modules
MFA Enhancement
Layer unbreakable on-device cryptographic signatures on top of existing MFA/OTP flows.
Decentralized ID (DID)
Self-sovereign Decentralized Identity. You own and control your keys entirely on-device.
Self-Custodial Litecoin
Self-custodial Litecoin payments with optional MWEB privacy and energy-backed PoW settlement.
AI Agents & A2A
Verifiable cryptographic authority for autonomous agents. Secure agent-to-agent interactions without credential sharing.
Google Cloud-Backed
Google Cloud-backed infrastructure with 99.99%+ uptime SLAs. Audit-ready and globally scalable.
SDK, REST API & MCP2
Full SDKs + AI-powered MCP2 tools for rapid integration. Start small with MFA, scale to sovereign identity.
Who It's For
Use Cases
Developer Experience
Drop-in cryptographic identity. Works alongside your existing stack — no rewrites required.
// npm install @kakr/pteri-sdk
import { PteriAuth } from '@pteri/sdk'
// Verify a signed request — no backend secrets needed
const result = await PteriAuth.verify({
payload: request.body,
signature: request.headers['x-pteri-sig'],
policy: 'payment_authorization'
})
if (!result.isValid) {
throw new UnauthorizedError('Authority not proven')
}
// Deterministic. Binary. No guessing.
return processTransaction(result.claims)No tokens. No gimmicks. Straightforward service pricing.
