Router

SolRouter (ROUTER) is a private AI inference layer on Solana that encrypts a user's prompt on-device and decrypts it only inside an Intel TDX trusted execution environment provided by Phala, so a centralized provider never sees the plaintext. It targets the exposure of private information when conventional AI APIs read prompts on their servers by replacing mere privacy promises with hardware isolation and on-chain proof. Its core mechanism uses X25519 per-request key agreement plus Arcium RescueCipher encryption in the browser, relays ciphertext, decrypts inside the TDX enclave to run the model and re-encrypts the reply, writing a verifiable receipt per sealed call to Solana via Light Protocol compressed accounts, with a TypeScript SDK and MCP connecting to tools like Cursor and Claude.

In the ecosystem SolRouter works with confidential-computing infrastructure such as Phala, Arcium and dstack, serving developers and AI agents that need data confidentiality; unlike centralized inference the private keys and plaintext never leave the trusted boundary. Its privacy path covers only open-weight models with an 8K context ceiling, and some agent connectors such as Notion and GitHub are not inside the sealed processing path.
