Biti Pro builds Biti Wallet, a self-custody wallet for cross-chain transfers from EVM networks to Solana with route, fee and simulation transparency before signing.
Biti Pro is a self-custody wallet maker working on cross-chain asset transfers between EVM networks and Solana. Its product, Biti Wallet, supports transfers from Ethereum, Base, Arbitrum, Optimism, Polygon and BNB Chain to Solana. Before a transaction is signed, users are shown the route, costs and fees, and a simulation of the outcome; transaction state remains visible throughout the swap lifecycle.
The company's technical work spans self-custody wallet technology, key management and cryptography, transaction simulation, and blockchain interoperability. Recovery phrases are encrypted with AES-256-GCM, with key derivation using 310,000 PBKDF2 iterations. Keys are managed locally, and the wallet adheres to open standards - BIP-32, BIP-39 and BIP-44 - so recovery phrases remain portable.
Biti Pro states a preference for professional-grade wallet experiences built around operational clarity rather than hype, and for orderly, predictable cross-chain behaviour. It reports integrating no third-party analytics or tracking SDKs. The company operates in the cryptocurrency, DeFi, blockchain and digital asset management sectors. Founding year, team size and funding are not disclosed.
