Secure Key Signing
Secure Crypto Wallet Key Signing with Treza
How Treza enables crypto platforms to protect private keys during transaction signing — with verifiable hardware isolation and multi-cloud flexibility
The Billion Dollar Risk
Crypto wallets — from consumer apps to institutional custodians — rely on private keys as their most critical asset. If a private key is leaked or misused, funds are gone forever. Traditional approaches force teams to trust cloud providers, internal admins, or custom infrastructure — all of which create unnecessary risk.
Treza eliminates this problem by providing secure enclaves for wallet signing. Keys are never exposed to developers, cloud operators, or even Treza itself. Every signature is backed by cryptographic attestation that proves the operation was executed inside an isolated, tamper-resistant environment.
Enter Treza’s Secure Signing Platform
Treza orchestrates Trusted Execution Environments (TEEs) — including AWS Nitro Enclaves, Intel SGX, and AMD SEV — into a unified platform for crypto key management.
Instead of building directly on provider APIs, developers integrate once with Treza’s SDK or API. Treza handles the complexity of enclave provisioning, attestation, key management, and audit logging across providers.
The result: provably secure signing at scale — without re-engineering infrastructure.
Real-World Scenario: Signing a Transaction with Treza
Store: Private keys are encrypted and registered in Treza’s key vault. Keys never appear in plaintext outside of an enclave.
Trigger: An app or service calls Treza’s signing API (e.g., to sign an Ethereum transaction).
Enclave Execution: Treza routes the request into a secure enclave on the chosen provider. Inside the enclave, the encrypted key is decrypted and used for signing.
Sign: The enclave produces the signature. The private key never leaves enclave memory.
Verify & Return: Treza returns the signed payload along with an attestation proof showing which enclave and code performed the operation.
Audit: Attestation logs and metadata are stored for compliance and operational visibility.
The Business Impact
Maximum Key Protection: Keys remain invisible to developers, admins, and cloud providers.
Verifiable Security: Every signature includes attestation proof, so clients can verify it was enclave-backed.
Simplified Integration: Treza abstracts away AWS APIs and other providers into a single signing interface.
Multi-Cloud Ready: Treza isn’t tied to a single vendor — enclaves can run across AWS, GCP, Azure, or on-prem TEEs.
Technical Architecture: How Treza Builds It
1. Unified API/SDK
Developers call Treza’s signing API instead of raw AWS Nitro Enclaves or KMS.
2. Enclave Orchestration
Treza provisions secure enclaves across supported providers, handling lifecycle and scaling.
3. Attested Decryption
Treza uses enclave attestation to securely release encrypted key material only to verified enclaves.
4. Secure Signing
Keys live and die inside the enclave. Only signed transactions exit.
5. Audit & Proofs
Treza automatically collects and exposes attestation reports, logs, and compliance artifacts.
Getting Started: Implementation in 3 Steps
Register Keys with Treza Import encrypted private keys into Treza’s secure key vault.
Integrate Signing API Replace direct signing logic with Treza’s SDK or API call.
Verify Proofs Use Treza’s attestation artifacts to verify every transaction was signed inside a secure enclave.
ROI Calculator: What’s This Worth?
Breach Prevention: A single leaked key can cost hundreds of millions. Treza makes exposure cryptographically impossible.
Compliance Efficiency: Built-in proofs reduce audit and regulatory overhead.
Developer Velocity: Integrate once with Treza — no need to manage Nitro Enclave APIs, KMS policies, or cloud-specific glue.
Client Confidence: Offering enclave-backed signatures positions your wallet or custody service as best-in-class secure infrastructure.
The Future of Enclave-Backed Signing with Treza
MPC + Enclaves: Treza will combine enclaves with multi-party computation for even stronger custody guarantees.
Validator Signing: Proof-of-stake validators can sign blocks securely with attested enclaves.
Cross-Cloud Flexibility: Run signing workflows on AWS today, move to Intel SGX or on-prem TEEs tomorrow — with no code changes.
Ecosystem Tools: Treza’s SDK will offer wallet builders, DeFi protocols, and exchanges easy ways to adopt enclave-based signing.
