We've filed our application for authorization as a virtual asset service provider (PSAV) with the Central Bank of Brazil. 🇧🇷 Brazil is a global reference in crypto and stablecoin adoption, and a market that matters deeply to us. Pix and stablecoin settlement already move money across borders every day, and we believe there is still a lot ahead. This comes on the heels of our regulatory progress in the US. We're excited to keep building this new chapter alongside regulators, with compliance at the center of how we grow. Thank you to the entire @blindpay team for the effort and dedication behind this filing, and to everyone who supported us along the way. A special thanks to Pinheiro Neto Advogados for their partnership throughout the process.

self-setting deterministic defaults TLDR if a specific selection is repeated n times, it becomes the default option and not everything needs AI to feel smart Yes I know none of this is new, but somewhere in the times of AI people forgot about it Once a pattern is clear, the app just sets that choice for you with no AI bs, no guessing, no latency I think these autonomous smart defaults are more useful, cheaper and more efficient than most AI features you could add to an app And the best part to me is that they cost nothing lol A bunch of these autonomous settings are coming to the next version our web app too (which is gonna be one of the greatest web dashboards out there btw. Linear/Resend/Vercel typa experience for money)

You can plug your entire global payments infrastructure into your Grok bot. Pick a bot and plug in the BlindPay MCP. 12 of them are live at blindpay.com/bots

BlindPay has received approval for its first U.S. state Money Transmitter License (MTL). With 25 MTL applications submitted across the United States, this marks an important step in our long-term U.S. expansion. Compliance has been part of our foundation from day one. This approval reflects months of preparation, regulatory engagement, and work across our team to build trusted global payment infrastructure. Our focus now is on progressing the remaining applications and continuing to strengthen our compliance program as we grow.

Today we're introducing Payables. Let your business pay invoices and bills directly from stablecoins. Upload an invoice, boleto, Pix codes, utility bill or tax bill. We extracts the amount, beneficiary and due date, then routes the payment through the right local rail.

we’ve been visiting some @BlindPay customers in Paraguay this week first time here you can read about a market all day but actually being here and seeing how money moves makes a huge difference people are buying products with: > USDT > Pix > Guaraní > US Dollars with multiple currencies accepted in the same store Paraguay has become a major commerce and redistribution hub for the region, especially for Brazil the country imported almost $17B worth of goods in 2025 and you can actually feel that scale on the ground it honestly feels like a mini New York for Latin America (this photo looks like Times Square lol) there’s advertising everywhere, stores packed at 8am and people from all over Latin America buying products and there are almost two different worlds here: > smaller local stores > huge shopping centers with global luxury brands there’s basically something for every kind of customer seeing this in person changes how you think about building financial infrastructure for Latin America really excited for the next chapters here!

should we create a BlindPay Developer Associate program? customers keep asking us: “do you know any developers who can help integrate BlindPay?” and we almost always recommend the same developer he’s integrated BlindPay for multiple customers, knows the API extremely well and constantly gives us feedback on how to improve the DX this is already happening organically, so the idea is simple: > train developers on BlindPay > certify the ones who know the product deeply > connect them with customers > let them make money from our ecosystem we also just hired an AI engineer who built a working neobank on top of BlindPay in only 3 prompts we’re now improving the docs for a world where both developers and agents should be able to go from idea to working financial product as fast as possible the best developer ecosystems create value for everyone building on top of them
