# Inco SVM — Confidential Computing on Solana Inco Lightning is a confidentiality layer for Solana that enables developers to build applications where sensitive data remains encrypted even during computation. It uses Trusted Execution Environments (TEEs) to deliver verifiable confidential compute — no new chain, no new wallet required. > **Note:** Inco SVM is currently in **beta** on Solana devnet. Features are subject to change. ## Overview - **Encrypted Types** — `Euint128` and `Ebool` handles representing encrypted values stored off-chain - **Homomorphic Operations** — Arithmetic, comparison, bitwise, and control flow on encrypted data via CPI - **Access Control** — Allowance PDA system for granting per-handle decryption permissions - **Attested Decryption** — Ed25519 signature-verified decryption through TEE covalidators - **Confidential SPL Token** — Privacy-preserving token standard with encrypted balances and transfers - **Client SDK** — `@inco/solana-sdk` for encryption, decryption, and utility helpers ## Architecture ``` Client Solana Program Inco Covalidator (TEE) │ │ │ ├─ encryptValue() ──────────►│ │ │ ├─ CPI: new_euint128 ─────────►│ │ │◄─── handle (u128) ──────────┤ │ ├─ CPI: e_add / e_sub / ... ──►│ │ │◄─── result handle ─...
