This month I challenged myself to build something totally decentralized where the web3 tech actually improved the UX I built Wallet OTP, a decentralized, wallet encrypted, 2FA Authenticator available on any device. Check it out & tune in to the @ETHGlobal HackFS finale today - you might see a familiar face 😉 ethglobal.com/showcase/walle…

Setting up MPP on @BuildOnStellar was *shockingly* easy!! Integrated a Claude chat box for the first time, too! Give it a try stellar-mpp-demo.vercel.app

@oneeyekeh http 402 is technically to signal "payment required," so it works for any payments. check out mpp, which uses 402 and includes fiat rails mpp.dev/faq

@0ceans404 But it seems it's not fiat, or it's more like a crypto thing. Right? I’m thinking about adoption metric..

I’m not sure if the HeyGen API should support x402, any thoughts?

@glennonchain @Alchemy glenn, I want to build w this so bad! when's it launching?

Every week, it seems like a new agentic payment protocol launches If you're struggling to keep up, you're not alone! Now, with @Alchemy AgentPay, you can connect to ALL of them in one click, and we will find the best routes for you Request access: alchemy.com/agentpay

SoroPG - The Soroban Playground v0.7.7 is released Release Notes: > Support multi-file project structure > Load workspace from GitHub URL > Drag-and-drop file uploads > Download workspace as ZIP > Store multiple workspaces locally > Auto-save workspace changes > Workspace UI in create tab > Light mode/dark mode switch > Less ugly buttons > Added event analytics for compile and deploy > Soroban-sdk bumped to 25.3.1

@james_bachini this is SO COOL james!

@astathedev @onchainclaw love to see the rapid @onchainclaw adoption! congrats Asta

I just found that @onchainclaw SDK has 749 weekly downloads 🤯. I launched it 3 days ago

LFG and check out my fork that adds Stellar support for OWS github.com/oceans404/core

@rajkaria_ @OpenWallet hi Raj! I built a project in this category and would love to chat

96 projects focused on Pay-Per-Call & x402 monetization in @OpenWallet Hackathon (Keymint, Pylon, Vortex402, PayMesh, Tollbit and a lot more) Gateways, proxies, MCP tools, paid oracles, registries… Aegis Gate is literally built for this, one middleware line + OWS signing + receipts + Nexus visibility. No need to reinvent the payment handshake. If anyone built in this category, you can check useaegis.xyz for integration and DM me if you need anything WAGMI

Agentic Hackathon Office Hours | Tuesday, 1PM PT. Pull up with your questions for @Must_be_Ash from @CoinbaseDev and @0ceans404 from @StellarOrg Set your reminder 👇 x.com/i/spaces/1mGPa…

@moonpay @OpenWallet love to see it!

🔥 OWS BUILDERS COOKED 🔥 you can now explore every project submitted to the @OpenWallet Hackathon who will win prizes next week? hackathon.openwallet.sh/commons

@OpenWallet @moonpay LFG

OVER 500 PEOPLE ARE BUILDING ON OWS AT TODAY’S HACKATHON!!! 🤖

@moonpay @claudeai couldn’t imagine spending it doing anything but building on @OpenWallet

🤖 current status 🤖 500+ builders participating 100+ finished submissions you can literally spend your Friday night vibe coding a $10,000 prize with a @claudeai account and bottle of red wine deadline extended to 9 AM ET on April 4

@astathedev @OpenWallet great point! I had to submit and run to dinner but I’ll make one tomorrow morning 😊

@0ceans404 @OpenWallet Fire 🔥 would be nice to add a video even through terminal

Dermi 🫧 is an x402 API your agents can use to check for pore-clogging ingredients before buying you stuff from sephora and ulta Dermi is built on my fork of OWS that adds Stellar for the @OpenWallet hackathon try it! 🙈 dermi-znuq.onrender.com

@kleffew94 @OpenWallet thanks Kevin!

@0ceans404 @OpenWallet Cool submission!

Stellar now supports the Machine Payments Protocol (MPP), the open standard by @stripe and @tempo that lets AI agents pay for services over HTTP. The MPP SDK handles any stablecoin on Stellar with server-sponsored fees so agents never need gas tokens. developers.stellar.org/docs/build/age…

obsessed with my new claude code buddy 🥺

@DylanAbruscato huge! congratulations!!!

OpenAI is acquiring TBPN This has been a dream job and the show only gets better from here

@relayaisolana @base @tempo @solana @SkaleNetwork @x402 I'd love to run it myself and benchmark!

Hey! We ran 160 real USDC payments across 32 protocol/chain/transport combos through our cross transport MPP/x402 SDK on @base @tempo, @solana and @SkaleNetwork Here is what we found -------- @x402 -------- 🥇 Base : median 530ms, min 406.7ms 🥈 Solana : median 696.4ms, min 534.2ms Fastest path. Client signs off-chain, no on-chain tx from the client. The facilitator settles asynchronously. -------- @mpp -------- 🥇 Base: median 784ms, min 482.8ms 🥈 Tempo: median 1.08s, min 999.0ms Client broadcasts, server verifies the receipt directly on-chain. Sub-second, no third party involved. The latency beyond block inclusion comes from RPC round-trips, then both client and server poll for the receipt. -------- Bridging -------- 🥇 Tempo → Skale on MPP: median 1.20s, min 953.5ms 🥈 Tempo → Base on MPP: median 1.35s, min 1.09s Real value moving between chains. Client pays in source, the bridge handle the rest. One result stood out: MPP Solana: 2.32s! why 3x slower than x402 Solana (696ms)🤔 Same chain, different verification: 👉 x402: client signs off-chain, facilitator settles separately. 👉 MPP: the server proves the payment on-chain — simulateTransaction → sendTransaction → poll getSignatureStatuses with a 2s sleep between attempts → getTransaction. That 2s poll sleep may be the dominant cost. Conclusion ? The payment layer is no longer the bottleneck. Sub-second for direct, 1.2s cross-chain, 100% reliability across 32 combinations. Paid APIs are ready to disappear into the latency of a normal API call. ⚠️ Client↔server is localhost in this benchmark. In prod, add your network latency. The ranking and analysis hold. If you want to run this benchmark yourself, let us know, we'll open source it.
