A safety rule for one transaction can't promise the outcome of a cross-chain journey.
Ethereum Foundation's October 5 research says native transaction assertions could enforce an outcome within one transaction on one network. A route spanning several chains sits outside that guarantee.
For $ETH users researching these proposals, that boundary matters: each additional step needs its own safeguards. The design is still under development, so this is a proposed protection with a defined scope, not a feature every wallet provides.
