Frequently Asked Questions

Kakr Labs builds cryptographic trust infrastructure. We replace fragile systems like passwords and API keys with verifiable, math-based proofs.

PTERI is the product suite. It includes the Wallet, the Authority Layer, and the interfaces (APIs) that allow you to use that authority.

PTERI is identity and authorization infrastructure first: passwordless MFA, runtime authorization, and verifiable evidence for every action. The Litecoin blockchain sits underneath as a supporting component for tamper-evident settlement and verification. You don't need to be a crypto expert to use PTERI.

You do. Private keys are generated and stored on your device (in the Secure Enclave) and remain customer-controlled. Kakr Labs does not hold or escrow your keys.

Your identity and funds remain yours. Because your keys are stored on your device and settlement is recorded on the public Litecoin blockchain, your ownership does not depend on our servers.

Instead of typing a secret password (which can be stolen), your PTERI Wallet signs a login request. The system verifies the signature mathematically. No secrets are ever shared.

Yes. PTERI is ideal for enterprise identity (IAM), replacing OTP codes and phishable credentials with hardware-bound cryptographic identities.

Yes. The wallet uses your device's biometrics (FaceID/TouchID) to unlock the signing key. Biometric data is processed by your device's secure hardware and is not sent to Kakr Labs.

No. PTERI provides infrastructure for you to hold and move value. We do not act as a custodian or an exchange.

Yes. PTERI supports self-custodial Litecoin payments with customer-controlled payment credentials.

PTERI signatures are instant. Settlement on the blockchain follows standard block times (approx 2.5 minutes), but authority verification happens in milliseconds.

AI agents usually cannot 'own' things or sign contracts. PTERI gives agents a distinct cryptographic identity, allowing them to sign actions and hold authority delegated by humans.

PTERI allows for 'scoped authority'. You can give an agent budget limits, time limits, or specific permission scopes, and revoke them instantly.

No. PTERI is API-first. You verify identities and transactions using standard REST/gRPC APIs in languages you already know (JS, Python, Go, etc.).

Yes. We offer a full testnet environment where you can build and test flow without using real funds.
