JUST IN: Lazarus Group is building their own perp DEX and prediction market.

My 2026 goal: Master Rust, build a killer portfolio of projects, and land my first full-time tech job as a Rust developer! 🦀💻 A free Rust Book would accelerate things big time. Already following! 🚀 Good luck everyone! 🎉

Create ERC-8004 and x402 ready AI agents in 1 minute! Introducing "npx create-trustless-agent" ✨ It supports: - Ethereum sepolia - Base sepolia - Polygon amoy - Solana (coming soon) Built on top of @CoinbaseDev x402 and @pinatacloud IPFS.

📣 Calling all builders: 🧙‍♂️ x402 is a new standard for web payments 🗓️ Today we launch a virtual hackathon until Jan 5 🚢 Ship something incredible on x402!!! 🏆 No financial prizes, just mentorship and distribution 🫡 Join us today:

And we are live.

x402 made payments native to HTTP. I made USDC payments native to sound waves ✨ Not as a gimmick. As a proof. 1/ The setup: @CoinbaseDev's x402 protocol embeds payments into HTTP. It's brilliant. But I started wondering, if we can pay over HTTP, what else can we use to pay? Spoiler: anything that supports 138 bytes 2/ The realization: x402 is built on EIP-3009 - a 2020 standard that lets you sign payment authorizations offline. Someone else submits it on-chain. The signature just needs to get from A to B. HTTP is one way. Sound is another. 3/ What I built: x402hz: two devices negotiate a payment through 2400Hz audio tones. - Seller beeps "pay me $0.001 USDC" (30 bytes) - Buyer's device decodes, signs the EIP-712 for the transferWithAuthorization locally, beeps back (108 bytes) - Seller settles on-chain Total: 36 seconds of beautiful noise. 4/ The bigger point: If payments can travel over sound, they can travel over: - QR codes - NFC - Bluetooth - Light pulses - Anything that carries 138 bytes The payment primitive is transport-agnostic. x402 picked HTTP. The next protocol might pick something weirder. 5/ What this proves: EIP-3009 separates three things: - Authorization (offline, cryptographic) - Transport (literally anything) - Settlement (on-chain) x402 nailed #1 and #3. x402hz proves #2 is wide open. 6/ Credit: Huge thanks to the @CoinbaseDev x402 team for building the protocol. I just... took it off-road. 7/ Next steps Code is open source. Go make payments, travel over something ridiculous (repo in the comments). 138bytes. That's all you need.

Another Quiz Tournament at @Alchemy Discord is over! This is the (top-30) September Leaderboard Congrats to @LTebbs2 for winning the Quiz Master Level 2 NFT! 🙌 Kudos congratulations and huge thanks to everyone for participating! 🎉 Join us for the next one 👉 discord.gg/alchemy-builders

this weekend 170+ shape builders from all over the world spent 36 hours hacking with 1 simple instruction: "build an nft × ai project on @shape" the community really cooked. here are a few that caught attention ↓

48 hours of pure chaos building AI NFT Forge on @shape with @Alchemy - my brain is fried 🤯 !! Some Ai generated NFT images:

If you’re into #Web3, there’s no better place than building with @Alchemy 🪄 Not just the best tools, but also one of the strongest, friendliest communities out there. Come learn, build, and vibe with us

We are testing stuff! @Giulia_Trinidad @arya_akhare
