Biti builds self-custody wallet technology for moving assets across blockchains. Its product, Biti Wallet, handles cross-chain transfers from EVM networks - Ethereum, Base, Arbitrum, Optimism, Polygon and BNB Chain - to Solana, with routes, fees and expected outcomes shown to the user before any transaction is signed.
The engineering work spans cryptography, blockchain interoperability and transaction behaviour. Key management is handled locally, with AES-256-GCM for encryption and PBKDF2 key derivation run to 310,000 iterations. The wallet follows open standards (BIP-32, BIP-39, BIP-44) and integrates with hardware wallets. Transaction simulation is used to make cross-chain outcomes legible before approval, with transaction state visible throughout the swap lifecycle.
Biti operates in the cryptocurrency, decentralised finance and digital asset management space. The team's stated principles centre on self-custody, pre-signing route review and user understanding ahead of transaction approval; the company also takes a firm privacy stance, running no third-party analytics or tracking SDKs. Its stated aim for cross-chain behaviour is that it be orderly and predictable rather than opaque.
