World’s most valuable bank now on @ethereum
@jpmorgan deposits powered by @Alchemy
How it works:
JPM Coin represents dollars deposited at JPMorgan. Approved institutional clients can move those dollars on Ethereum around the clock—to pay each other or buy tokenized assets.
Think of how stocks went from paper certificates to electronic trading. The shares stayed the same; moving them became easier.
This is a similar shift for bank deposits: the dollars are still at JPMorgan, but Ethereum becomes a network for moving them.
we just made @brexHQ’s Top 25 Fastest-Growing Software Vendors - only blockchain company on the list!
the next generation of software is getting built onchain 📷
Proud to support @CashApp as they scale stablecoin money movements!
Verifying transactions and continuously reconciling ledger state across EVM + Solana means a simple balance update can reach users within seconds.
Great engineering by the teams making it work!
📱 .@CashApp put stablecoins in front of 59M+ people.
🤫 None of them have to think about a blockchain.
🔁 3.5M+ reconciliation checks/day
📲 ~360K settlement events/day
🔗 EVM + Solana
Take a look 👇

Crypto products in Northeast Asia now up to 8x faster ⚡️
@Alchemy powers more API calls than Google does searches
All of those tokenized stocks, stablecoins, RWA, memes now loading before you can blink in the most active crypto region of the world.
Thanks for having me on the pod @MichaelWaitze! Let's check back in and see where agent usage is at SF Tech Week 2027
Agents now drive more than half of traffic on Alchemy, and serving them has meant rewriting nearly everything, says @gponcin, CTO and COO at @Alchemy, a blockchain developer platform.
Agent usage does not follow human patterns. Humans rarely work at 2 a.m. or on weekends, but agents do. Trading agents expect the platform to be available around the clock, with latency under 10 milliseconds on everything.
To meet that, Alchemy has changed the way it operates. The goal is that engineers are not woken at 3 a.m. because something broke, so most interventions are now automated.
Guillaume describes the change as a complete rewrite. Alchemy is rebuilding component by component, starting with the operational ones. That covers customer support, incident handling and the maintenance of blockchain nodes, which have already shifted to fully automated.
The same approach applies to making the platform easy for agents to address, including Model Context Protocol and API design. Alchemy is going back to first principles and asking what agents actually want from the platform.

Developer activity as true measure of chain popularity.

Big upgrade: Your agent can now use your @Mastercard with spend controls & audibility on @agentcardai
Excited to partner with the incredibly tech forward team @Mastercard. Stay tuned for more 👀

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

Really excited to be partnering with Mastercard on this project!
Mastercard plans to roll out an agentic payment option this week for everyday purchases, through a partnership with the startup Alchemy on.wsj.com/4d9hZj9

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.

“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. 💪
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
