We're hacking in person @tempo today, so what more fun than chat-native stablecoin micropayments on Slack and X? Tag your friend, tip them for their hard work! Works with a tenth of a cent, or any dollar amount you want! Demo in reply :) x.com/tipbotgg/status/206148…

Level up your company's use of AI with Centaur Something we've been iterating on since January and using daily at Tempo that's made our team way faster This is what @sama and @patrickc were talking about at Stripe Sessions in April, similar to @tobi's River too!
Open Sourcing Centaur: Multiplayer, self-hosted, secure agents for Slack. Centaur has been transforming how @paradigm and @tempo invest, build and research. Now you can run it yourself on infrastructure you control. Instructions below.

Onchain subscriptions are live on @tempo and @mpp! Continuing to add more key payments primitives that should “just work”
MPP now supports subscriptions, starting with stablecoins on @tempo. Subscriptions are built for flows including: • Recurring API access and MCP tools • Paid plans and memberships • Usage bundles that renew on a schedule Live on Tempo, with more payment methods coming soon.

Excited to be bringing stablecoins to Canada! 🇨🇦 My personal goal is to move my personal Norbert's Gambit volume onchain this year on Tempo.

CADD is live on Tempo. @TetraDigitalGrp's CADD is the first Canadian dollar stablecoin issued by a regulated financial institution, approved by Alberta Treasury Board and Finance, and backed by National Bank, ATB Financial, Wealthsimple, Shopify, and others.

BREAKING: @stripe is developing streaming payments for token providers, which will allow users to pay for each token as it's delivered with stablecoins, says CEO @patrickc. "[It's] the intersection of crypto/ stablecoins, and usage-based billing."

Have been thinking about FX lately, and it seems to be a huge opportunity in stablecoins, which no one has solved yet (at scale). Here is the problem statement: If you're a bank in the UK or the EU, how exactly do you onramp to USD-denominated stablecoins? A TradFi path is: open a nostro account with a US FI (if you can). Send GPB/EUR to your FX broker, in two days, get USD to your nostro account. Send USD to the issuer to mint USD stablecoins. T 2 FX and a nostro account kind of defeat the whole purpose. There's got to be a better way. And this "better way" probably involves someone who'd use their balance sheet to get your GBP/EUR and send USD to the issuer instantly.

Why Link is a big step forward for consumer crypto - 250 million consumers have a Link wallet with a stored fiat payment method. - It supports a global set of payment methods like cards and bank accounts, as well as UPI, PIX, etc. - It now stores stablecoins (on Tempo!) in a consumer-friendly UX. No complicated addresses required. Just a digital dollar balance that can be spent at 5 million merchants. - It’s agent-native. The 5 million Stripe customers (as well as anyone who supports MPP) can immediately accept payments from agents using Link with no additional work. Virtually *every* leading AI company is a Stripe customer and works with Link. Ultimately, this is crypto as plumbing providing faster, cheaper and global without any consumer behavior change necessary.

Stripe obsesses over API design. For Stripe Sessions we turned our well-worn API design principles into an app that reviews your API for $2. We liked it so much we’re making it public for 30 days. api-reviews-by-stripe.vercel…

I am genuinely stoked for @tempo's new virtual addresses feature that they announced yesterday. I think this could be a real sleeper hit and I'm guessing that most people who don't have first-hand experience building on-chain don't realize it. In almost 8 years building in crypto I've had to solve the deposit-address problem at literally _every single company_ I've worked at. Every time its the same build out: Generate a unique address per customer Sweep funds back to a master wallet Manage gas in every leaf address Reconcile timing differences Handle the edge cases It's the kind of thing that sounds simple in a design doc and then can end up eating a quarter of your team's roadmap. It is _so cool_ to make this a protocol primitive - and totally obvious in hindsight. No sweeps, no per-address gas, no state bloat from millions of customer accounts sitting around with minuscule amounts of dust in them. This is another one of those things that - if you've built any kind of systems in payments before - seems like an absolute no-brainer, yet somehow we don't have any blockchains with virtual accounts as a first-class citizen yet (Solana's ATAs partially get there but you still need to pay rent per account). Bullish on how much friction this will remove for teams bringing AR / AP on chain and on more protocols bringing more "obvious" payments primitives on chain in general. Hat tip.

You have no idea how much of my life was spent working on this problem (back at Coinbase). @tempo now firing silver bullets on a weekly cadence.

Replying to @tempo
Per-customer deposit addresses are live on Tempo. On most chains, giving every customer a unique deposit address means initializing, monitoring, and sweeping a real onchain wallet for each. With virtual addresses, funds credit directly to a master wallet at the protocol layer.

We're building Tempo to bring real-world payments onto stablecoins. Today we released new capabilities for: • Subscriptions • Auto-pay • Per-customer deposit attribution • Invoice reconciliation • ... and more. Live on mainnet now. Details in thread.

Feels great to be moving the world onchain, and to get to work with customers that are so excited about it!

Enterprises are bringing stablecoin payment flows into production on Tempo, including @DoorDash, @stripe, @CoastalBankWA, and @arq_finance. We're also launching our Stablecoin Advisory to help more enterprises build real-world payments workloads on stablecoins.

passkeys don't get enough credit for how much they have shaped and secured the internet these past 2-3 years. when a site has it, it is usually a positive signal on how seriously they take security. going from a world of 2fa auth codes that dont always sync / sites that only allowed SMS to this has been an undeniable upgrade.

Tempo Zones are pragmatic privacy If we're serious about bringing the world onchain, we need to meet businesses where they already are That is why @tempo is optimizing for privacy and controls businesses expect today AND the self-custody and interoperability crypto offers

These are exactly the kinds of primitives that are going to onboard millions (and eventually billions) onto blockchain wallets And, of course, we need both these kind of pragmatic solutions, and the more cash-like private systems for anyone who wants them (e.g., Zcash)

And while those systems offer excellent cryptographic solutions, their integration paths for businesses are significantly more challenging technically, legally, and operationally for businesses
