Safe (Gnosis) Multi-Sig Co-Signer

Architectural Layers & Silicon Defenses

Layer 1: FIPS 140-3 L4 Silicon Master Vault (Active Tamper Mesh / Battery Backup): Physically protecting the bundler master keys, paymaster reserve keys, and institutional wallet root seeds.
Layer 2: WebAuthn secp256r1 Hardware Acceleration (Custom P-256 Elliptic Curve Coprocessor): Verifying standard smartphone biometric Passkey signatures without expensive on-chain gas costs.
Layer 3: ERC-4337 UserOperation Simulation Core (EVM State Execution & Gas Estimator): Simulating UserOperations in an isolated enclave sandbox to prevent front-running, gas exhaustion, and bundle invalidation.
Layer 4: Bundler & Paymaster Relay API (JSON-RPC 2.0 / eth_sendUserOperation / gRPC): Exposing standardized bundler endpoints to enterprise decentralized applications (dApps) and mobile wallet SDKs.

Cryptographic Telemetry & Compliance: < 12 ms (UserOp Validation & Bundling) | 120,000/s (P-256 Passkey Verification) | 100% (ERC-4337 & ERC-7579 Compliant) | Zero-Gas (Optimized Pre-Compiled Verification)

Portefeuilles de contrats intelligents de nouvelle génération adossés à des racines de confiance en silicium

The transition from externally owned accounts (EOAs) to ERC-4337 Account Abstraction and smart contract wallets revolutionizes Web3 usability, enabling social recovery, session keys, and batched transactions. WalletHSM provides enterprise bundlers, wallet infrastructure providers, and institutional treasuries with hardware security modules that validate user operations and sign transactions at scale.

Core Engineering Areas

ERC-4337 UserOperation Bundler Enclave — Engineering secure, high-concurrency bundler nodes that aggregate user operations into standard Ethereum transaction blocks.
WebAuthn & Passkey Smart Wallet Integration — Bridging native smartphone biometric chips (Apple FaceID, Android Fingerprint) with on-chain smart contract wallets.
Modular Smart Wallets (ERC-7579) & Session Keys — Hardware management of ephemeral session keys, automated recurring subscriptions, and institutional multi-signature custody.
