QELVA
Qelva is a privacy-native identity and transaction layer built for Solana. It introduces a seedless, multi-persona identity system combined with an intent-based execution model to eliminate the exposure of a user’s real wallet on-chain. All cryptographic keys are generated and stored locally, while the architecture separates identity, intent, and execution to ensure strong metadata minimization. Qelva uses a relayer-based private execution pipeline, where user intents are validated off-chain and executed on-chain by a relayer, breaking the direct link between users and their transactions. The system incorporates Split & Delay obfuscation, persona-scoped wallets, and non-custodial authentication (username + PIN) to provide lightweight but practical privacy for everyday Solana usage. Qelva is designed for users and developers who want private transfers, persona separation, on-chain activity obfuscation, and a secure identity layer without seed phrase exposure or centralized trust. It serves as a foundation for privacy-preserving wallets, dApps, and automated systems on Solana.
