AppChain Custom Key Management Systems

Eliminate single points of failure with distributed key generation and signing. Our MPC architecture ensures no single party ever has access to a complete private key, providing institutional-grade security for treasury and hot wallet operations.

Integrate with certified HSMs (AWS CloudHSM, GCP HSM, Thales) for root-of-trust key storage. We manage the complex orchestration layer, allowing your smart contracts to securely sign transactions via on-premise or cloud HSM clusters.

Define and enforce transaction policies with role-based access control (RBAC). Set multi-signature thresholds, spending limits, whitelists, and time-locks programmatically to match your organizational security posture and compliance needs.

Manage keys and sign transactions natively for Ethereum, EVM L2s, Solana, Cosmos, and other major protocols from a unified interface. Our abstraction layer handles chain-specific signature schemes (ECDSA, EdDSA) seamlessly.

Every cryptographic operation is immutably logged with non-repudiation proofs. Generate comprehensive audit trails for SOC 2, ISO 27001, or financial regulatory requirements directly from our dashboard.

Deploy across multiple availability zones with automatic failover. Our active-active architecture and geographic key sharding ensure zero downtime for signing operations and instant recovery from regional outages.

We design KMS architectures that meet specific jurisdictional requirements for digital asset custody (e.g., SOC 2, GDPR, MiCA). Isolate and manage keys for regulated vs. non-regulated operations within a single system.

Eliminate the catastrophic risk of a centralized key store. Our designs implement distributed key generation (DKG), multi-party computation (MPC), and geographic secret sharding to ensure no single breach compromises your chain.

Define precise, role-based policies for validator key usage. Enable multi-signature approvals for upgrades, emergency pauses, or treasury transactions directly within your chain's governance model.

Guarantee validator uptime and transaction finality with automated, non-custodial key rotation, failover, and disaster recovery procedures. Our managed services include enforceable SLAs for system availability.

Maintain an immutable, cryptographically verifiable log of all key-related actions—generation, usage, rotation, revocation. Essential for security audits, compliance proofs, and incident investigation.

Avoid the costly migration from a basic KMS later. We build on modular, upgradeable architectures that seamlessly integrate new cryptographic standards (e.g., post-quantum algorithms) and scaling solutions.

We conduct a comprehensive security assessment to design a key management architecture tailored to your AppChain's consensus mechanism and threat model. This includes defining key lifecycle policies, access controls, and disaster recovery procedures.

We implement secure key generation, storage, and signing using Hardware Security Modules (HSMs) and MPC/TSS protocols. This eliminates single points of failure and ensures private keys are never exposed in plaintext.

Our team develops and audits the on-chain components, including governance modules for key rotation, multi-sig wallets, and permissioned access controls specific to your AppChain's validators and operators.

Every line of code undergoes internal review followed by a formal audit from a leading third-party firm like Trail of Bits or Quantstamp. We provide a detailed report and remediate all critical/high findings before deployment.

We deploy your KMS to a testnet environment for integration testing with your AppChain nodes. Following successful validation, we manage the production rollout with zero-downtime migration strategies.

We provide 24/7 monitoring dashboards, alerting on anomalous signing attempts, and operational support. Our service includes automated, scheduled key rotation procedures to maintain long-term security.
