A 12-word phrase that solely works inside one pockets shouldn’t be self-custody — it’s vendor dependency with further steps. Thanos Pockets builds on BIP requirements so your phrase belongs to you, not the app.
There’s a model of “self-custody” that sounds proper till you really want it. You maintain a restoration phrase. The phrase was generated by a particular pockets app. The app makes use of a proprietary derivation path or a non-standard key era course of. The day you’ll want to get well your property with out that particular app — as a result of it was discontinued, delisted, or just stopped working — you uncover that your “restoration phrase” doesn’t get well something exterior the atmosphere it was created for. You have been holding the phrase, however the pockets was holding the keys.
This isn’t a hypothetical edge case. It’s the quiet consequence of wallets that prioritize their very own continuity over the portability that self-custody is meant to ensure. A phrase that solely works in a single app provides you a single level of failure dressed up as decentralization — which is arguably worse than simple custody, as a result of it carries the chance of custody with out the security web of a custodian who can assist when issues go mistaken.
Thanos Pockets is constructed on BIP39 for phrase era, BIP44 for multi-account derivation, and BIP84 for native SegWit Bitcoin addresses. These are usually not proprietary to Thanos. They’re open, extensively carried out requirements shared throughout the vast majority of severe self-custody wallets. A phrase generated in Thanos Pockets will work in another BIP39-compatible pockets that helps the identical derivation paths — which is to say, in a lot of the wallets that take requirements compliance severely. The phrase is transportable not as a result of Thanos Pockets is beneficiant, however as a result of it was by no means purported to personal the phrase within the first place.
That portability has a sensible implication past emergency restoration. It means the person shouldn’t be locked into Thanos Pockets as the one interface for his or her property. If a greater software comes alongside, or if entry to Thanos Pockets is interrupted for any purpose, the trail to restoration doesn’t run by means of Thanos Pockets’s servers, Thanos Pockets’s help crew, or any course of that requires Thanos Pockets to be operational. It runs by means of the phrase, the usual, and whichever BIP-compatible pockets the person chooses to revive into.
The open-source positioning of Thanos Pockets reinforces the identical precept from a special angle. An inspectable codebase means the derivation logic may be verified independently — that the pockets truly implements BIP44 and BIP84 the best way it claims to, slightly than implementing one thing near these requirements that diverges in methods a person would solely uncover throughout restoration. Proprietary is the alternative of that. With Thanos Pockets, the requirements declare is verifiable, not simply said.
Self-custody means the property are yours and the trail to them is yours. A phrase tied to a single app’s continued existence doesn’t meet that definition, no matter what the advertising and marketing says. BIP-standard compliance is the baseline that makes the definition actual — and it’s the baseline Thanos Pockets was constructed round from the beginning.
