Stablecoins with Bitcoin properties

[Bitfinex @bitfinex]

USDt once ran on Bitcoin. Cost and speed took it elsewhere.

@RGB_Hub and @utexocom are bringing it back to where it belongs, anchored to Bitcoin, settled over Lightning, while keeping contract logic off-chain.

This is how.

@bitfinex @RGB_Hub @utexocom USDT on Bitcoin is going to be huge. We can't wait for it!

⚡️ KaleidoSwap demonstrates that RGB protocol assets can run natively on Liquid Network, Blockstream's federated Bitcoin sidechain, without bridges, wrapped tokens, or a parallel protocol.

In a deep dive published on 13 July, the KaleidoSwap engineering team showed that RGB's commitment mechanism, embedded inside a standard Taproot output following BIP-341, is accepted by standard RGB verifiers on Liquid without modification. The only new code required was 207 lines across seven files to handle Liquid transaction reads. None of the protocol's 45 existing tests needed changes.

The team issued a real RGB20 asset on Liquid and demonstrated an atomic swap between an RGB asset on Bitcoin and one on Liquid, with no custodian involved. The swap is bound by a shared secret: either both legs complete, or neither does.

A key motivation is Simplicity, Blockstream's formally verifiable smart contract language now live on Liquid mainnet since July 2025. KaleidoSwap wrote a Simplicity covenant that consensus enforces on every seal spend, requiring it to carry a valid RGB commitment. This makes Liquid's spending conditions spending conditions on the asset itself.

The result is an open-source proof of concept, not a production-ready product. The team has submitted the patch as an RFC in the official RGB repository. KaleidoSwap, a founding member of the RGB Protocol Association alongside Bitfinex and Tether, describes RGB on Liquid as the natural next scenario for its market-maker network.

New on the blog: why v0.11.1 is the only version to build on for RGB Protocol on Bitcoin, including stablecoin adoptions:

Summed in 3 sections:
-testing
-claimed features of other versions that do not hold up
-ecosystem usage on mainnet

@giacomozucco @Arvolear Better privacy and smaller onchain footprint is always desirable 🥰

[Viktor Ihnatiuk @VIhnatiuk]

Great initiative. @utexocom & @BoostyLabs fully support bringing RGB assets to @Liquid_BTC. Spoke about this today only with @FulgurVentures & @olegmikh1

Would love to see the whole Bitcoin ecosystem behind this:

@Blockstream @RCasatta @adam3us @Excellion @kravchenkopo @distributedlab @peterktodd @giacomozucco @planb_network @FedericoTenga @bitfinex

This could become one of the biggest catalysts for BTCfi, PayFi and programmable USDT on Bitcoin.

[Liquid Network 🌊 @Liquid_BTC]

Private, self-custodied assets that move across Bitcoin's layers without a bridge or a middleman. @kaleidoswap's new proof of concept shows RGB tokens could live natively on Liquid, with programmable rules enforced by Simplicity. No wrapped tokens, all open source.

[Lnfi Network @LnfiNetwork]

Recap: RGB as the meta asset standard

Kudos to @kaleidoswap for the proof of concept on RGB's interoperability on Liquid.

This would mean: one single unified bitcoin ecosystem despite multi layers and token standards.

We will be adopting RGB as the meta asset std and this will serve as the foundation for cross layers' liquidity, interoperability and price discovery.

[RGB Protocol Association @RGBAssociation]

Congratulations to our member @kaleidoswap for a remarkable piece of research: a proof of concept bringing RGB Protocol on Bitcoin assets natively to Liquid, in a 207-line non-breaking patch. This is exactly the kind of work the RGB Protocol Association is proud to support.

[Utexo @utexocom]

Looks like @kaleidoswap just casually explained how RGB unlocks interoperaibility across Bitcoin's layers!
