Wallet security is not only about protecting a private key. It is also about deciding where that key is allowed to operate. TRON’s developer recipes include an offline-signing workflow in which a transaction can be prepared and signed on an isolated machine, then broadcast from a separate online machine. This can be useful for certain high-security or operationally sensitive environments. Separating signing from broadcasting reduces the need for the signing environment to have direct network access. It does not eliminate every risk: teams still need to verify transaction details, protect offline devices, control how unsigned and signed transactions move between systems, and secure backups. Developers should choose an architecture appropriate to their threat model and operational needs. For some use cases, a hardware wallet or hardware security module may be more suitable. Security is strongest when the process is designed deliberately, documented clearly, and tested before real funds are involved. @trondao @justinsuntron #TronEcoStar
