Threshold Key Management System

Your Private Key
Is the Biggest Vulnerability.

Mitigate the risk of a full infrastructure compromise. TKeeper uses Threshold Cryptography to split authority across nodes. No single server holds the full key, making your infrastructure resilient to insiders and breaches. Open-source under Apache 2.0 License.

Threshold Signing

NIST P-256, secp256k1, and Ed25519 curve support. Key shares stay split across nodes and signing requires quorum. Fully crypto-compatible.

Threshold Cipher

Encrypt and decrypt through threshold cryptography so no single host can expose full key material in operation.

Full Key Lifecycle

Generation, refresh, rotation, expiration, and destroy policies with versioning.

Audit evidence built with focus on Compliance

Reduce audit risk and review overhead with verifiable operation evidence and built-in asset context in one place.

Tamper-evident audit evidence

Prove who did what and when, with cryptographic integrity on every operation-level audit event.

Sensitive payloads stay out of logs

Request bodies are not persisted in audit trails, while event integrity and accountability remain verifiable.

No silent audit blind spots

If audit sinks are unavailable, secured actions are denied so teams do not run critical flows without evidence.

Faster audits and investigations

Built-in asset inventory and policy mapping make scoping, incident response, and regulator review significantly faster.

4-Eye Control

Cryptographic multi-party control combined with policy-enforced human authorization makes TKeeper suitable for both hot and warm key operation paths.

See Why It Matters

Byzantine-Resilient.

TKeeper tolerates up to (n-t) node failures while threshold operations continue safely under quorum rules.

Even when nodes fail or an incident is isolated, TKeeper keeps operations running under quorum and preserves high availability for business-critical flows.

Learn how TKeeper detects and behaves when a node tries to violate the protocol or when nodes fail during an operation.

Who needs TKeeper?

One architecture for high-stakes teams: split key authority across nodes so no single breach, insider, or host can authorize alone.

CeFi & DeFi

Secure hot-wallet operations in an environment where more than $250M has been lost to reported private-key leak incidents over the last 3 years, excluding insider-risk losses.

Supply Chains

Raise operational security by splitting key authority across facilities, partners, and regions instead of one central keeper.

Banks & Payments

Apply cryptographic dual-control for settlement and treasury operations, reducing insider abuse and single-system compromise risk.

Government

Enforce inter-agency separation of duty so no single department can authorize critical actions alone.

KMS & HSM vs TKeeper

Compare your current key model with threshold-based operations before rollout planning.

Aspect	Standard KMS / HSM	TKeeper
Full secret key exists	Yes	No
Primary protection	IAM/ACL + hardware boundary	Cryptographic quorum (t-of-n) + IAM
Signing	Single-key sign	Threshold signing
Encryption	Single-key decrypt/encrypt	Threshold encryption/decryption
Key generation	Centralized	Distributed without reconstruction
Key lifecycle	Rotate/Destroy	Refresh/Rotate/Destroy
Host compromise / Insider Risk	May expose or allow abuse of full key	Resilient until less than t nodes are compromised
Audit logs	Service/provider logs	Operation-level logs
Asset inventory	Often external	Built-in mapping
Latency	Low	Interactive (higher)
Fault tolerance	Stops on outage	Tolerates up to (n-t) failures
