Invisible Wallet: Zero-Knowledge Key Management for Multi-Chain Support

Abstract

This paper presents the Invisible Wallet system, a zero-knowledge key management approach that eliminates traditional key storage while providing universal multi-chain support. The system uses multi-factor key derivation (wallet + TOTP + guardian), Argon2id13 key derivation function, progressive security model based on transaction value, and social recovery mechanisms with guardian system. Unlike traditional wallets that store seed phrases or private keys, Invisible Wallet constructs keys on-demand from multiple factors, ensuring that keys are never stored in persistent form. We describe the architecture, implementation details, and security characteristics of Invisible Wallet, demonstrating its effectiveness in production deployments. The system achieves zero-knowledge key management without seed phrases, supports multiple blockchain networks (EVM, Solana, Bitcoin, etc.), and provides social recovery through guardian-based mechanisms. Performance evaluation demonstrates efficient key derivation and multi-chain operations while maintaining strong security guarantees.
