… in Frontend I've completely removed the getPrivateKey function from frontend/src/solanaRPC.ts. The application no longer requests or handles the user's raw private key. I refactored the sendToken function to delegate the signing process to the user's connected wallet. It now constructs the transaction and passes it to the wallet to be signed securely, which is the standard and correct practice. Fixes AIxBlock-2023#168

Issue #168 Critical Security Vulnerability - Private Key Exposure in Frontend
The Solana RPC handling code in the frontend directly requests the user's raw private key from the connected wallet provider. The key is then used within the browser's JavaScript environment to manually sign and send transactions. This practice fundamentally breaks the security model of modern crypto wallets and exposes users to a catastrophic risk of total fund loss.
This vulnerability has been addressed by completely removing the
getPrivateKeyfunction fromfrontend/src/solanaRPC.ts. The application no longer requests or handles users’ raw private keys.Additionally, the
sendTokenfunction has been refactored to delegate the signing process to the user's connected wallet. It now constructs the transaction and passes it to the wallet for secure signing, aligning with standard best practices for wallet integration.This resolves a critical security vulnerability that could have led to private key compromise and the potential total loss of user funds.
