x402 A2A payments in the wild
10 years committed to those building the onchain economy. 10 years of OpenZeppelin.
(4/12) Have you deployed on mainnet? Congrats—you’re in the top ~0.02% of all addresses 🎊 In total, we’ve seen ~5.6M deployer addresses, but the top 500 account for 57% of all contracts.
programmable Ethereum part 1: programmable Ethereum, VMs, and ISAs part 2: zk everything (costarring: RISC-V, EVM) part 3: scaling lean Ethereum with leanVM and EVM 2.0 1/30
Wild to see @Figure_robot announce a $1B raise at a $39B valuation. This only adds fuel to the fire for robotics and will accelerate ongoing funding rounds for other major humanoid players like @Apptronik and @NEURARobotics, pushing their valuations even higher as investors FOMO…
Everything besides Ethereum L1 was a sidequest. That's not me saying it - this is Aave - the world's largest DeFi lender w/ $70 billion in value. We're on the verge of an Ethereum L1 renaissance. The L2 path is in motion - it's time to get back to L1. Scale L1 for DeFi.

100 ETH were assumed lost but could eventually be recovered. Here's what happened, how it became a happy ending and what's needed to prevent this from happening again. Context A user of Safe{Wallet} wanted to bridge 100 ETH from Mainnet to Base. But then they realized that they…

Status code 402 “Payment Required” has been a part of HTTP for decades, but was never used. x402 builds on HTTP rails to bring it to life. Now any server can request payment, and any client — whether an AI agent or a human — can respond with digital dollars like USDC.
