1. About BitFit Labs
We are building enterprise blockchain wallet powered by advanced Multi-Party Computation (MPC) Threshold Signature Scheme (TSS). This solution provides institutional-grade security for asset custody through distributed key management technology.
Core Features:
- Signature Scheme: 2/3 threshold signature distribution
- Multi-chain Support: Bitcoin (BTC), XRP, Solana (SOL), EVM-compatible chains (Ethereum, BNB Chain, Avalanche, Arbitrum, Polygon, etc.), TRON
- Hardware Integration: Support for Ledger and Trezor hardware wallets
- Secure Key Management: TSS nodes distributed across isolated environments with HSM integration
2. Key Responsibilities
- Infrastructure & Environment Management
