for the spark — one public idea, and we built it. Days, not quarters. On signet now. Let’s keep going. 🔥This one shipped because the whole team moved as one. Huge thanks to @FedericoTenga
It's live. 🫡
Wednesday @FedericoTenga asked for consignment data read in the frontend — never sent to a server — next to the BTC tx each transfer was committed to. Days, not quarters: it's on signet now.
The engine: rgb-lib compiled to WebAssembly, in your tab. Drop a .rgb file and the panel says it out loud — sent anywhere: 0 bytes.
What comes back: the issuance, every transfer since, each one's witness tx (opret / tapret), seals, amounts, and what each sender kept. Blinded receipts stay blinded.
Our test drop: 4 assets, 6 allocations, 7 transfers — 7 of 7 witness txs carried in the files, 7 of 7 anchored on bitcoin. Blocks 323,460 → 323,467.
No wallet. No seed. No account.
Credit where it's due: the idea is @FedericoTenga's — one public tweet, and it became a spec anyone could build. RGBMap is an independent team on the open standard: no permission asked, no vendor in the middle.
One thing worth saying plainly: no wallet exports consignments yet — that button is the ecosystem's last mile. Until it ships, consignment-export reads yours out of an rgb-lib wallet backup on your own machine, offline:
github.com/rgbmap/consignmen…
Looking forward to the day a wallet ships it — and to the other teams building on RGB. Then this page is one drag and one drop.
Sample, one click, no file:
rgbmap.org/signet/consignmen…
Read your own:
rgbmap.org/signet/consignmen…
If a file breaks the reader, we want to hear about it. Want a batch of signet packages to run through it? Say the word. #RGB #RGBMap
I've been getting quite a few DMs on X lately, but I don't check them very often, so apologies for the late replies!

RGBMap Officially Introduces a New Type of RGB NFT: Private UDA!
We now support Private UDA registration and consignment recognition, along with a detailed issuance guide that lets developers and creators build their own Private UDA!
Read the full article to explore the technology and how it works.
#RGBMap #UDA #RGBNFT
I hope more people will join in building the RGB ecosystem.
Thanks for the recognition, SatSea. Really glad to see you understand what we're trying to build with rgbmap-collection.
A real market needs more than assets. It needs a shared, verifiable structure.
That's the layer RGBMap is building for RGB UDA.
Excited to see SatSea bring discovery, pricing, and trading on top of it.
Much of what #RGBMap does now came out of questions @FedericoTenga kept asking. He tends to spot what is missing before we do, and several features exist because of it.
Thank you. #UDA is next for us.
RGBMap now supports NFT collections on RGB 🎨
We've opened an NFT collection standard: projects can open a collection and register each NFT (called a UDA on RGB) under it, with an item number, traits and artwork. Only NFTs signed by the same address as the collection count as members. Anyone else claiming your collection is flagged as a conflict and never counted. No approval step, just your own wallet signature.
How to register:
① Open a collection (before minting)
Enter a name and how many items, then add a cover (≤256 KiB), website, X and Telegram. Click "Sign with wallet", then "Open". The item count is not a supply cap; leave it at 0 to declare nothing.
② Register a UDA (after minting)
Export the contract consignment from the wallet that issued your NFT and upload it. Contract id, name, ticker and precision are read from the file and locked. Then add a logo (PNG/SVG/WEBP, ≤100 KiB) and artwork (≤512 KiB). Keep the artwork small, since it travels with the asset.
③ Join your collection & add issuer proof
Pick your collection, set the item number and add traits. Only a collection opened by the address you sign with will count the NFT. For issuer proof, add a DNS TXT record (rgbmap-issuer=) or post the manifest sha256 from your social account.
Once indexed, each NFT lights up its cell on the collection page 🟩
Registration is a signed declaration, not an approval or a listing, and published records can't be withdrawn.

@FedericoTenga @RGB_Bitcoin
Thank you for the invitation. I will be there tomorrow for the #RGB community call, grateful for the chance to share what we have been building.
See you at 15:00 CEST.
Thank you, @RGB_Hub, we're honoured, and honestly a little thrilled.
We'll be there on Wednesday 7 October at 15:00 CEST, live on X and Telegram, demo included.
A public map of RGB asset supply isn't something one team can draw on its own. It only works if the ecosystem draws it together, so we're not coming to pitch, we're coming to listen. Bring the hard questions, the doubts and the edge cases. We'd much rather be corrected early than consistent later.
Thank you for making room for us. See you Wednesday. #RGB

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!

RGB could become one of the most notable asset layers on Bitcoin, and Tether has announced plans to issue USDT on the Bitcoin network through RGB.
Growth isn’t only about the tech. It’s also driven by the builders, organizations, and communities behind it.
Here are some of the most worth-following accounts in the RGB ecosystem:
🧬 RGB Ecosystem Gateways
• @RGB_Hub — RGB news, tutorials, project updates, and builder interviews. A key hub for understanding RGB.
• @RGBAssociation — Official account of the RGB Protocol Association. Ecosystem coordination, developer support, partnerships, and growth.
🛠️ RGB Core Builders
• @FedericoTenga — Bitfinex RGB development lead. Working on RGB Lib, Lightning integration, and application infrastructure.
• @giacomozucco — Early RGB pioneer. Worked with Peter Todd and others on Bitcoin-native assets and client-side validation.

• @julnweber — RGBHorse builder. Working on RGB asset issuance and trading infrastructure.
Thank you @RGB_Pioneers RGBMap exists because the hard parts showed up in the field, not in the spec and because people kept the work on the open standard. Credit to the wider team, and to @FedericoTenga for the public idea that turned into a reader anyone can open. Grateful to be here.🙏
Recognizing an RGB Pioneer: @Elian_Ward
Elian Ward is building RGBMap, an open registry for RGB assets. He has written in public about the hard parts of a shared registry — canonical encoding, silent hash forks, and field problems that never show up in the spec — and then helped ship a browser consignment reader on signet after one public idea. He credits the wider team and keeps the work on the open standard, with no vendor in the middle. RGB users should know him because he is turning those field problems into tools people can actually open.
Applications for RGB Pioneers are now open!
Our goal is to connect contributors, developers, project teams, and users — giving great projects a chance to reach real users, while creating opportunities for community members to participate in testing, get early access, and earn rewards.
Want to become an RGB Pioneer? The application form is in our pinned post. Share your story and join the early RGB community. More opportunities for Pioneers are coming.
This is the loop we want: a public request, an independent implementation, and more teams able to use it. Happy to see Utexo and others building on the same standard.🙏
If you build on #RGB, six things will bite you.
None of them are in the spec. All of them are in the field.
I have hit five. The sixth is the reason I am building anything at all.

Tether is being lined up as THE digital dollar, and needs the #bitcoin rails we're working on to power world reserve level economy. Tether buys US debt (thanks to GENIUS act, so far $140bn), is a huge play I'm amazed isnt being reported more widely. CBDC no/Tether yes, it seems.
BREAKING: TETHER CEO JUST ANNOUNCED USDT WILL SOON LAUNCH NATIVELY ON #BITCOIN
THEY HAVE OVER 570,000,000 USERS WORLDWIDE
WORLDS LARGEST STABLECOIN ON BTC. MASSIVE 🔥
