Liquid · The work after the theft

After the theft, one builder stays on Liquid

OceanSlim argues that the contract designs can outlast the chain they run on. Elsewhere in the same reading, users are still asking how to get their money out.

OceanSlim has spent the past year building on Liquid and is not leaving after the September 6 theft. The argument in a new essay is about what can be built there, and what would remain useful if the sidechain itself failed.

The author describes anchor, an automated exchange whose pools are controlled by rules governing how their coins may be spent. In OceanSlim’s account, it has no administrator key or upgrade path. That work led to a Jan3 contract for a further prototype, still private.

The essay acknowledges the federation and the peg as trust assumptions. It calls for more scrutiny of Elements and a better release process, while arguing that the exploit did not invalidate the contract designs. The distinction is between losing a place to run the work and losing what the work taught its builder.

OceanSlim hopes to carry those designs to Bitcoin if it gains the needed capabilities, or to another experiment if it does not. The line that holds the argument together is The code is transitory. The understanding isn't. It is a case for continuing research, rather than a claim that the chain has become risk-free.

The user’s question remains more immediate. Tico reports intermittent access through Aqua: Sometimes Aqua enables peg-outs, but mostly not working. The report concerns access through that wallet, and illustrates why a chain processing transactions is only part of the recovery.

Leito is looking for an alternative: Is there an OTC trading desk for L-BTC?

The two conversations belong beside each other. The developer wants the work to survive. The holder wants a usable exit. Continuing to build answers one concern; it does not settle the other.

Client release

Coracle adds encrypted files in messages

Hodlbod announces Coracle 0.6.37, with support for encrypted files in direct messages and a setting to turn off link previews.

The release also separates cached events by logged-in account, adds social previews for shared Coracle links and rebuilds the app on welshman 0.10.

Less visible maintenance includes fixes to comment tags and signed-out errors, plus changes intended to reduce bandwidth and speed page loads. Relay reviews have been removed.

Wallets

Ecash App reaches the iPhone

Justin announces the iOS release of Ecash App, describing it as a Fedimint wallet. The app is also available on Android, Linux and macOS.

The announcement supplies both Apple and Google store listings. In a separate reply, Justin notes that Zapstore was the first app store to carry it.

Commerce on the timeline

The order gets its own inbox

Nostrich describes a marketplace built on the existing NIP-99 and NIP-15 listing formats, with products on seller profiles and purchases available directly from a timeline note.

The distinction is in how the client organises the activity: Orders use the same encrypted DMs, but get their own place in the app so they don’t get lost in chat.

The post says implementation details will be shared on GitHub once the release is complete. For now, the stated aim is to keep listings readable across compatible clients while giving an order somewhere more useful to live than the middle of a conversation.

In brief

Club Orange adds account switching

Club Orange adds multiple accounts in its latest update. A long press on Nearby opens the route to adding an account; subsequent switching takes one tap.

gittr for Android

The package wraps the hosted gittr.space forge and supports Amber/NIP-46 sign-in. Its listing explicitly distinguishes it from an offline, self-hosted copy.

The perfect shirt committee

Paul Keating asks for a plain cotton shirt with some style. The network supplies a fabric discussion.

Ben suggests House of Blanks, emphasising the absence of logos and collar labels.

West Major favours a relaxed cotton-and-hemp blend from Jungmaven, while acknowledging that it misses the all-cotton brief.

Marc puts forward Stafford shirts, with a caveat about shipping.

Keating offers one reassurance: Don’t worry it’s not a suit.
