Iris Wallet

Open-source wallet for Bitcoin and RGB assets. Developed by @bitfinex's RGB team

[Iris Wallet @iris_wallet]

Mainnet version of Iris Wallet is now available in the Play Store! Issue, send and receive RGB assets onchain

In RGB, the receiver makes the first move. That puts the choice of what to reveal, a blinded UTXO or one in clear, with the person being paid.

@RGB_Bitcoin has the details.

Super cool stuff

[KaleidoSwap @kaleidoswap]

👾 After Liquid, we took RGB to Arkade.

RGB is a meta-asset protocol: one asset, many Bitcoin layers.

In our research prototype, an RGB asset moves off-chain in milliseconds: no channel, no custodian, checked by the receiver.

@bitfinex @kaleidoswap @RGB_Bitcoin Amazing

[Bitfinex @bitfinex]

Good to see @kaleidoswap shipping atomic swaps over Lightning, built on @RGB_Bitcoin.

[RGB Protocol Association @RGBAssociation]

RGB Protocol was on the Talks Stage at bitcoin++ Berlin, with @kaleidoswap.

The team introduced Swap Service Provider Specifications, and built KaleidoPay, a reusable BOLT12 QR carrying the layers accepted by the receiver.

Keep up to good work @kaleidoswap!

New Community call: Presenting @RGBMap_

· Wed 7 October · 15:00 CEST
· Live demo on X and Telegram

A new tool in the RGB ecosystem: building a public map of an RGB asset supply.

How does it work? Why was it created?
Come find out next Wednesday!

[Bitfinex @bitfinex]

We love to see the Bitcoin ecosystem grow. 🧡

@kaleidoswap's extension now supports your own Lightning node, Arkade-to-Lightning swaps and @RGB_Hub asset access for dApps.

Ecosystem Spotlight:
at the Bitcoin Asia Conference, @birk1907 participated in the "Pragmatic Maximalism" panel.

Does Bitcoin need stablecoins? Should toxic maximalism change culturally?

Full recap with the video in the first reply:

[KaleidoSwap @kaleidoswap]

⚡ Play with RGB Lightning nodes and assets.

1. Run a node and link it to the Extension
2. Run a second one on the Desktop App
3. Issue an RGB asset
4. Send it between the two

Still signet, break it while it's free.

[Bitfinex @bitfinex]

A private contract can settle on Bitcoin without going on-chain, looking like an ordinary transaction outside.

The anchor makes this possible, a transaction ID and cryptographic proof tying the commitment to Bitcoin.

Nicely done, @RGB_Hub @RGBAssociation

[RGB Protocol @RGB_Bitcoin]

RGB Bytes: how RGB Protocol on Bitcoin commits many contracts with one on-chain footprint.

Multi Protocol Commitments merkelize several contracts into a single tree, and only its root goes on Bitcoin. One commitment, one output, any number of contracts underneath.

RGB assets now move over Lightning inside @WDK_tether.

Any wallet on WDK gets this without building the RGB stack. Issuance on Bitcoin, payments on Lightning.

The infrastructure keeps shipping. ⚡️

Built by @utexocom.

⚡️ 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.

[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.

[Federico Tenga @FedericoTenga]

Must read, thanks to RGB flexible and modular design it can be used on top of Liquid sidechain and fully leverage the recently released Simplicity smart contract language to build all kind of financial applications
