When deploying data storage strategies, "only I can decrypt" sounds like the safest approach—until a critical moment makes you regret it—such as losing that core NFT or your membership expiring.

Some protocols' Seal feature supports programmable access policies based on smart contracts, like "NFT A holder can view." Theoretically flexible, but it hides a fatal risk: logical deadlock.

Imagine this scenario. You set up strict access conditions relying on a third-party oracle or the contract address of an NFT project. As a result, if that project upgrades its contract, your old NFT suddenly becomes invalid, and the private data stored here can no longer be accessed—permanently locked out.

So my approach is: any conditional encryption strategy should forcibly include a "backdoor clause." Specifically, set a universal private key stored cold as the ultimate administrator, kept completely offline under normal circumstances, only activated when the smart contract logic crashes or external dependencies fail.

It may sound a bit against the ideal of "code is law," but in reality, when facing bugs, we need a physical key.

Damn, this is why I always keep a spare key. No matter how perfect the code is, it can't withstand an upgrade from the project team.

Haha, really. I’ve fallen into this trap before—once the contract is upgraded, the funds are gone. --- Using a backdoor private key is something I also do; otherwise, you might really get locked out. --- "Code is law" sounds sophisticated, but in reality, you need to leave an exit. --- Setting up conditions step by step, only to have the project team ruin it with an upgrade—that feeling is unbeatable. --- Storing a key in a cold wallet might be a bit "cheating," but it has saved me countless times. --- Relying solely on logical protection is definitely not enough; at critical moments, you also need a physical backup. --- Only after an NFT becomes invalid do you realize what permanent locking really means. By then, it’s too late to regret. --- The worst isn’t being hacked; it’s being trapped by the conditions you set yourself. --- If the oracle breaks or the contract changes, all previous conditions become useless paper. --- So my current principle is to be as strict as possible but still leave a backup.

Really, just thinking about decentralization can lead to losses. Have you ever encountered a project team running away after upgrading the contract? The data is completely gone. The backdoor key trick is brilliant, it violates ideals but it’s a lifesaver. The moment an NFT becomes invalid, you’ll regret it to the bone. Cold wallet backups are truly an insurance policy. No matter how perfect the code is written, it can’t withstand real-world bugs. Relying on third-party services will eventually backfire, I’ve learned that. Honestly, you still need to leave yourself a backup plan, or you’ll be foolish.

It's just all talk and no action. Listening to "code is law" is enough, but when the contract is upgraded, your NFT instantly becomes worthless. That's the reality.
