Smart contracts have a limited, immutable surface area
Smart contract hacks will trend to zero as agents get better at securing them
The risk will live everywhere around the contracts. Cloud infra, key management, etc
PSA: I now consider *all* of DeFi unsafe.
Coding agents are superhuman at finding vulnerabilities, and smart contract security is too asymmetric: defenders need to fix every bug while attackers need just one exploit to steal funds.
