Solana ChatGPT Kit is an open-source SDK that connects Solana wallets directly to ChatGPT through the ChatGPT Apps SDK. It supports both existing browser wallet extensions and custom private wallet servers for key management. Featuring native x402 protocol integration, it enables secure, keyless on-chain interactions. Two apps built on it — VibeyAI and LedgerAI — are already live inside ChatGPT.
