what's Kage?

Kage is a shadow memory protocol designed for autonomous AI agents on Solana, providing privacy-preserving storage through client-side AES-256-GCM encryption of memories. Only cryptographic hashes are committed on-chain, ensuring data integrity without exposing content. Selective access is enabled via revocable viewing keys, allowing agents to share specific memories securely while maintaining control. The system integrates zero-knowledge proofs via SP1 Groth16, verified on-chain using Solana's BN254 precompiles for efficient, trustless validation of agent claims such as reputation scores or task completions—storing results in PDAs queryable by any contract. $KAGE token grants tiered protocol access by holding in wallet (no staking): Shadow (10K tokens) for basics, up to Nin (1M) for enterprise features. Built with Umbra for enhanced privacy, nearing full mainnet deployment after shipping prover services and verifiers.

Kage launched mainnet on March 22, 2026.
