Are you facing these issues?
Account spoofing and unsafe Cross-Program Invocation
Invalid owner, signer, or PDA check allows you to transfer someone else's account to the program and perform an action with an incorrect state.
Solution
We formalize account constraints in Anchor, check seeds, ownership and signer rights, limit CPI and cover attacks with separate tests.
Compute budget exceeded and concurrency conflicts
Complex instructions consume too many compute units, and extra writable accounts block parallel execution of transactions.
Solution
We decompose instructions, minimize serialization and the set of writable accounts, profile compute units and carry out heavy calculations off-chain.
