SwapRail is a cross-chain self-custody crypto wallet designed to provide a professional, trustworthy experience for moving value across networks. The product emphasizes clear, readable route summaries, pre-sign fee visibility, transaction simulation, and a single coherent wallet surface that prioritizes EVM-to-Solana flows (Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain -> Solana). Security-first features include local key encryption, hardware wallet support, smart-contract risk warnings, and continuous execution state visibility, with destination-aware flows that help users continue actions such as staking after settlement.
