Explain Solana Security Shifts from EVM to SVM

Solana’s SVM separates logic from storage using Program Derived Addresses (PDAs) secured via anchor’s init, realloc, and close. Cross-Program Invocation (CPI) requires PDA signer validation to prevent impersonation. SPL Token mints manage decimals and supply; USDC supply is 9.7B. Lack of PDA access control risks fund loss. Solana transactions max out at 1,232 bytes, bundling atomic instructions.
