PROACTIVE AI SYSTEMS engineers institutional-grade crypto wallets across mobile, web extension, and hardware-integrated platforms. We specialize in Multi-Party Computation (MPC), Account Abstraction (ERC-4337), multi-signature governance, and cold storage custody systems.
Unified HD wallet architecture supporting Bitcoin, Ethereum, Solana, Polygon, Arbitrum, BSC, and Cosmos with automated RPC failover nodes.
Threshold signature schemes (TSS) eliminating seed phrase vulnerability by splitting private key shares between user devices and institutional backup nodes.
Account abstraction enabling gas sponsorship (paymasters), automated session keys, social logins (Google/Apple), and atomic transaction bundling.
Hardware-backed cryptographic security integrating iOS Secure Enclave, Android Keystore, FaceID, and hardware security modules (HSMs).
Native DEX aggregation, cross-chain bridge integrations, staking portals, and interactive NFT galleries seamlessly embedded into the wallet interface.
Pre-execution transaction simulation, malicious domain detection, smart contract approval management, and zero-leak cryptographic audits.
Our cryptography team builds zero-knowledge, battle-tested wallets with intuitive UX that drive institutional trust and mass retail adoption.
Absolute privacy where only the user possesses the cryptographic keys to authorize on-chain transfers.
Custom n-of-m multi-signature approval rules for corporate treasury management and funds security.
Native iOS, Android, Chrome Extension, and desktop applications sharing synchronized state.
