Working on @tempo now 🫡

[Tempo @tempo]

The Merkle team is joining Tempo.

We're excited to build the infrastructure for payments at scale, together.

[Kartik @Slokh]

This has been absolute game changer for us. Can’t imagine going back to a world without it.

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.

Deel is rolling out stablecoin payouts for employee salaries on Tempo.

RELEASING RETH 2.0!

Reth is now faster, smaller, and ready for the future of crypto infrastructure.

Gigagas per second has not just been achieved, it's been blown out of the water.

We've put in a ton of work in this, and we're incredibly proud to be sharing this with everyone.

We've added MPP / Tempo Wallet support to Foundry - out on latest nightly.

- foundryup -n tempo
- cast bn -r tempo
- cast send erc20 <...> -r tempo --from `tempo wallet whoami --json-output | jq -r .wallet` (to be made less verbose)

MPP myths

"MPP only works with Tempo"
No. It's payment method agnostic — works with crypto and fiat, any chain. It's already been extended to Bitcoin Lightning; there's a draft extension for Solana.

"It costs 1.5% to use"
No inherent cost to using MPP. Individual payment methods may charge fees, but that's no different than today. Blockchains have different fees. Fiat methods have different fees.

"It's less open"
MPP launched with 4 payment methods on Day 1: Tempo (stablecoins), Stripe (various payment methods), Visa (cards broadly), and Lightspark (Bitcoin Lightning). Visa and Lightspark were each able to extend MPP in a matter of days. MPP does not have a complicated foundation structure — it's designed to be simple and extensible by anyone. It's also been submitted to the IETF as a web standard.

"It's session based vs. pay-per-request"
MPP supports both. The most basic version is pay-per-request. Sessions (payment channels) are useful when you want many small payments in succession at the speed of APIs, not blockchains. Fewer API round trips also means MPP is faster in practice.

"MPP is specifically designed for Tempo / Stripe"
It's designed to be as simple as possible. No complicated facilitator. No assumptions about specific smart wallet implementations, stablecoins, or chains. It separates secure HTTP communication from the payment rail. That's why Visa and Lightspark could extend it so quickly.

"What have you been working on?"

[Georgios Konstantopoulos @gakonst]

we just open sourced the Tempo Wallet CLI with built-in MPP support, it's what the https://t.co/62ewrs42pp uses.

@sweetman_eth @varunsrin @mpp Don't have the code and it wouldn't work anymore anyway. We haven't added websocket support to the mpp sdks yet, but will do that soon and then should be easy to use!

[Kartik @Slokh]

Few weeks ago I built a demo that live generates music using Lyria 3 with streamed payments over websockets!

Pretty cool demo showing the potential of @mpp sessions imo.

(audio on)

[Kartik @Slokh]

@pirosb3 Hm looks like they're not available on StableEnrich anymore, will update docs :/

[Kartik @Slokh]

@gregskril i'm dying

@0xtanishk Sandwich Payment Protocol

[Kartik @Slokh]

@mpp @tempo Have been working on our Tempo CLI that interfaces with both, check it out!

[Kartik @Slokh]

Excited to see what people build with @mpp and @tempo now that they're public!

Been a crazy first 6 weeks btw 🫡

[Tempo @tempo]

Tempo Mainnet is live! Starting today, anyone can build on Tempo through our public RPC endpoints.

Alongside mainnet, we’re introducing the Machine Payments Protocol, an open standard for machine payments.

[Georgios Konstantopoulos @gakonst]

planning hackathon on &lt;redacted&gt; on Thursday March 19th in our new office in sf about some cool stuff we've been buliding - if you're in sf please email me your github to georgios @ tempo dot xyz - website w/ more stuff hopefully up tmr

@GSkrovina I was at a restaurant paying and the terminal showed the emergency alert as well while I was signing 💀

[Kartik @Slokh]

writing code by hand just to feel something

[Kartik @Slokh]

Pretty cool seeing projects changing hands rather than winding down recently.

@farcaster_xyz -> @neynarxyz
@LC -> @masknetwork
@foundation -> @Blackdoveart

Assuming a combination of them being built on an open crypto stack and AI tooling making it easier than ever before to build context quickly.
