MPP TestKit

MPP TestKit is no longer just an idea or a single SDK - we’ve shipped the stack across all the major rails developers actually use: • npm for TypeScript / JavaScript • PyPI for Python • crates.io for Rust • Go for backend systems This is the foundation for builders who want to work with HTTP 402, x402 flows, and machine payments on Solana without waiting around for “someday.” We built the tools. We shipped the stack. Now it’s your turn to build on it.

@CalebSol 👀

I want to help a project blow up. Which project deserves it?

@bloodweb3 $MTK

I NEED THE NEXT 450X. THE TICKER IS?

@vibhu @perps MPP will win

Solana will win @perps

@solana @TryNoahAI 📦📦📦

@TryNoahAI Shipping era starts 🌊

We spent months building a new Vibe Coding layer on @solana Then we rebuilt it all. Introducing Noah 3.0: Shipping Era 🧵

@Pumpfun this will look good ?

fits like a glove.

Don't just talk about MPP TestKit. Build on MPP TestKit.

Rust SDK is live. As promised, MPP TestKit now supports Rust - another step toward making machine payments accessible across every serious developer stack. HTTP 402 on Solana is no longer just a concept. It’s becoming a real multi-language standard. Explore it here: crates.io/crates/mpp-tes… github.com/mpptestkit/sdk… More SDKs. More builders. More rails for the machine economy.

We hired an intern👩‍💼 for our X .

Resources hub is live. We now have one dedicated place for all MPP TestKit writing, research, tutorials, and protocol breakdowns. If you want to understand HTTP 402, pay-per-request APIs, Solana settlement, and the machine economy - this is where we’ll keep publishing. Read the latest pieces: mpptestkit.com/resources

Phase 4 will be making it usable by machines. Private payments matter, but so does programmable access. HTTP 402 turns APIs into wallet-approved endpoints where agents, apps, and services can pay each other directly. That’s the lane MPP TestKit is building for. $MTK

GM. After a massive week of hardening the core infrastructure, we’re moving straight into the next phase of the roadmap. Today’s Focus: • Dev.to Tutorial Series: We are officially kicking off a deep dive series, starting with the TypeScript & Protocol guides to help you master the x402 handshake. • Rust SDK: Bringing the safety and performance of Rust to the stack with our official crates.io release.

Best project?

@mrinko We are waiting for the result.

today is my first day reviewing frontier submissions who are the best teams?

👀

We have officially launched a dedicated page to showcase the growing directory of applications built on the MPP TestKit stack. From autonomous agents to self-monetizing APIs, you can now track the live implementations of the x402 standard in one place. Explore the directory: mpptestkit.com/apps/ If you’re building on the rails, it’s time to get listed.

Give your terminal a wallet and access to pay-per-use APIs. No accounts. No keys. No subscriptions. Pay.sh is a CLI that works with Gemini, Claude Code, Codex, Openclaw, Hermes, and more. Aents pull from an open marketplace covering @googlecloud and 75+ other APIs from @TektonicCompany, @PayAINetwork, @rye, @crossmint, @agentcashdev, @corbits_dev, @moonpay, @paysponge, @atxp_ai, and more. Full tutorial below 👇

HTTP 402 is not a theory anymore. Wallet-approved API access, pay-per-use endpoints, no subscriptions, no billing mess. This is exactly the machine-payment layer MPP TestKit is building tooling for. More devs. More paid APIs. More MPP infra. $MTK is locked in on this narrative.

We have submitted a @CoinMarketCap listing request for MPP TestKit (MTK). Ticket ID: 1362554 This post is made from an official MPP TestKit account to verify the correct project details and token contract for the listing request.
