Solana Security

Solana account data can be read by any on-chain program. This is unlike an EVM smart contract's data which is encapsulated, and thus only accessible on-chain if the sc chooses to expose it

In a Solana transaction, a program cannot arbitrarily read data from just any address.

You MUST specify which accounts you wish to read from, upfront, BEFORE the program even begins to run 😦

This is a common complaint that it makes it hard to compose many solana contracts dynamically.
