Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sanctions Bypass: Sanctions validation was only performed at broadcastTransaction, missing the sender address and leaving a window before signing. The fix moved validation to buildTransaction to cover all inputs/outputs/change/receive addresses.
Sanction Enforcement Bypass: Basic address validation was replaced with a dedicated sanction check (assertAddressNotSanctioned) across all chain adapters, indicating the previous validation did not enforce sanctions.
Auth Bypass: The smart contract address check was applied to receiveAddress instead of sendAddress, allowing THORChain trades to bypass the restriction via a smart contract receive address.
