AI agents are moving from making recommendations to completing transactions. We are helping build the trust, authorization, and control frameworks needed for trusted agentic commerce through Agent Pay, Verifiable Intent, and collaborations like AgentCard with @Alchemy

Incredible to see the surge in new dev teams building on Robinhood Chain.
The ecosystem is expanding by the day. If you’re building on the chain, we want to hear from you.
Most people won't realize it for 6 months
Crypto going mainstream - 3.1x growth in new dev teams vs 1yr ago
@RobinhoodCrypto stock tokens driving the surge

At @Alchemy we really do earnestly believe blockchains will not kill all humans.
I personally think it’s <.01% chance within the next decade.
Jacob is correct here—we really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to.

“Running both a validator and RPC infrastructure on Stellar will give us visibility into the network that most teams building on top of it don’t have. That’s useful for issuers moving real-world assets onto Stellar, because they need the execution layer to be reliable before pricing or trading ever becomes a question. Pairing that with a standardized data layer like RedStone’s is what lets those assets actually get used in DeFi.” — @gponcin, CTO of @Alchemy

😱 "Don't worry, just give me your money."
...that's what agentic commerce sounds like to a lot of people.
87% of payments leaders say trust is the biggest barrier to agentic payments (not the rails).
So before you hand an agent a wallet, ask this question 🧵

Congrats to @tempo on the ATH! Nearly 15% of all volume since launch moved in a single week 🤯
Everyone knows stablecoin rails are becoming production infrastructure for global money movement, but this pace, this summer, is massive!
Proud that Alchemy powers Tempo builders with reliable RPC. 💪
Tempo just hit an all-time high in weekly stablecoin transfer volume.
More than $175M moved on Tempo last week, bringing cumulative volume above $1.2B since launch in March.
Enterprises are increasingly bringing payments infrastructure onchain.

Proud of the team - constantly iterating and tuning to shave off every last millisecond of latency, use-case by use-case. Every so often we hit big wins, like this one :D
today we're rolling out a 6-10x speed up for the entire crypto ecosystem
- custom hardware
- CPU optimization
- globally distributed data centers + custom edge proxy
eth_calls at latest now blazingly fast
after powering trillions of API requests & trillion of dollars for @jpmorgan, @Fidelity, @RobinhoodApp, @Polymarket we're now at the level of micro optimizing custom hardware to get the next level of performance

Excited to support Robinhood Chain at @Alchemy!
Robinhood Chain mainnet is live.
Fast, secure, AI-native, and purpose-built for real-world assets from day one.

AI agents are becoming economic actors. Not just assistants, they're buying domains, paying for compute, settling invoices, handling logistics. One human instruction becomes a chain of hundreds of transactions happening automatically in the background.
But the payment infrastructure was never built for this. Too slow, too high-value, wrong architecture entirely. That's the problem Agent Pay for Machines solves. And we're proud to be part of building it with @Mastercard.

Traditional banking rails weren't built for machines. AI agents need something different and our CTO @gponcin broke it down on @MilkRoadAI 🎙️

Super-talented team - Very excited to see you guys tackle this problem!
Over a decade ago at Uber, we were paying drivers across 40 countries. Their top ask: "Pay me faster." That stuck with me through Coinbase and Stripe, where I kept running into the same wall from different angles.
Today, Latitude (@rtp) is launching out of stealth. We raised an $8M seed round in Jan 2025 and have been building quietly since then.
