almost two years since Ethereum Acceleration
we're of course continuing to keep our heads down and build the code that the ethereum & broader evm ecosystem needs for the long run

Pump is bringing some of its execution infrastructure in-house. While we want to serve everyone, Relay is not a story about one app.
Relay is a platform that serves thousands of developers across wallets, payments, RWAs, prediction markets, perps, and trading, all built on the same belief: people shouldn’t have to think about which chain they’re on.
Users want one balance, instant execution, and zero friction. We’re making that the baseline for every onchain app, not just one.
On performance, Relay offers best-in-class latency, reliability and fill rates, across 100x the scale (txs), larger orders, more routes and use cases. The data is public (dune.com/relay/fomo-pump-fun…).
Two apps on Relay can see wildly different performance depending on how they’ve integrated. We’ve shipped a lot lately, so reach out and make sure you have access to all the latest and greatest.
Back to building. 🫡
Alpenglow is now live on Solana mainnet. ⛰️
Finality just went from ~12.8 seconds to ~150ms.
The biggest consensus upgrade in Solana’s history, built by @anza_xyz.
Second this. Lot's of insights and alpha in this. Great talk!
Last night I had the pleasure of attending the fireside between @gakonst (Paradigm) and @rauchg (Vercel). Guillermo shared so much valueable insight, specially:
MCP events and multi-agent collaboration look promising.
1. The open-model flip. Ten months ago open-weight models were close to 0% of tokens on Vercel AI Gateway. Last month they were about 70% of tokens, with proprietary at 30%. Spend still skews proprietary. The pattern: plan with a frontier model, execute with an open one.
2. Open follows closed in weeks. When a new small, fast proprietary model launched on the gateway, it became the most requested model in its history. A few weeks later there were ten open alternatives. He called this the new normal.
3. "Everything is code." That's why every lab pivoted to coding agents. If the model can code, it can drive Blender, run a sandbox, automate anything. Vercel's answer to lab competition: real open source and developer choice, which labs are disincentivized to offer. Companies end up using 4 or 5 models and need a layer that cuts across them.
4. Agents are the new users. Vercel now designs for agents, markets to agents, and asks agents what they think. Their DX team is now "agentic developer experience" and its goal for the year is verifiability: linters plus skills, correctness loops. They shipped a site that tells you whether agents can read your website. Most can't.
5. Rust is thriving for the same reason. It was less palatable to humans; agents persevere through anything, and they benefit from the correctness loops a strict compiler gives them. Vercel is also exploring what you can add to TypeScript to make it sounder and faster for agent-written code.
6. "Everything hackable will get hacked." Vercel put $1M on a sandbox-escape challenge. One researcher with a decade of red-team experience, a custom harness, and a mix of open and closed models found a novel Linux kernel vulnerability. Agents are the ideal security researcher, but human skill plus a good harness still wins.
7. Evals are the new marketing. Don't outsource "which model is best" to benchmarks you don't understand. Keep your own traces, reflect on them, derive your own skills, and judge models on your own work.
8. Hiring never stopped, through COVID and AI. He interviews for systems depth (distributed systems, networks, data flow) and agent orchestration. Output measured in changelog entries grows exponentially while headcount grows linearly.
9. On the agent stack: MCP has basically won and is getting more stateless. MCP events and multi-agent collaboration look promising. He thinks identity, wallet and permissioning should belong to the individual, and a cross-harness solution is needed because the future is many agents, not one.
Thank you @gakonst, @rauchg and @paradigm for a great session.
I also joined Relay 7 months ago and it's already been an exciting + inspiring time.
The team is locked in, and there is so much more ahead
my 8 months review at @RelayProtocol (we are hiring!)
> i joined relay because it feels like an underdog. no one talks about it much on CT, but every dev every crypto app i talked to uses relay.
> in 8 months, our customer base grew so much in both crypto native and payment verticals
> become one of the top bridges by volume
> as a BD, i'm lucky to have a team i can count on and a product that just works.
> both our reputation and data references make the pitch easy and obvious
> we are hiring BD (and other roles!) to accelerate our growth
> looking for someone who can talk to institutions, fintech, payment companies, high agency, good understanding of cross-chain/relay, preferably North America timezone
My DM is open if you're interested. Apply via the link in the thread.

What comes after Rust?
DHH is fundamentally right about Rust. For context, Vercel has been undergoing a Rust-ification (carcinization, technically 🦀) for a while.
One of the first projects we migrated was Turborepo, from Go to Rust¹. The migration completed, but the RoI was actually quite controversial internally.
While Rust was in our eyes better for low-level OS access, something crucial for a build system like Turbo, the human migration costs were very sustantive.
Go is very fast. It's beautifully designed. It's easy to iterate on. We were very conflicted about the migration, because it was *humans* writing the code, *even if we knew Rust was a better choice*.
The calculus has now changed. What's "best for humans" is no longer necessarily "best for business".
FWIW, it's also quite unlikely that Rust is the end-all-be-all toolchain. I'm quite certain there's greener pasture ahead, because Rust itself was designed before the 'supersonic tsunami' of agents hit.

Getting back into physical computing this year was not on my bingo card but here we are
🚨 MUSE ECOSYSTEM ALERT 🚨
today we are announcing Muse Gadgets!
this is an open-source ESP32 firmware and Linux SDK for anyone to make hardware that works with Muse
we are also releasing our own gadget—Muse Home Link—to enable your muse to work with your smart devices (TV, speakers, etc.)

You can now run Cursor cloud agents on your infrastructure, including pools of machines that automatically scale with demand.
This lets you give agents access to internal services or specialized hardware, while the agent loop stays in Cursor.

Prediction markets just got Wall Street-grade trading infrastructure.
@Kalshi’s live order book is now streaming on @DoubleZero Edge, a multi-venue, real-time market-data platform.
Institutional-grade market data is now open to anyone, anywhere.

Today we're launching Macro 1.0 — a new office suite for the intelligence age.
Macro is a unified workspace for your entire company, your team and your agents.
1. Fully open source. Built in Rust + SolidJS. Self-host if you want.
2. Designed as a single system: email, messaging, docs, tasks, agents, calls, and CRM all @-linked together in one tab.
3. Unified team-level memory for agents built over emails, team chat, tasks, PR's and CRM. Access the memory from Macro or AI or external agents via MCP.
We built Macro for ourselves because we wanted a single system for our whole company.
We didn't want to get slowed down by rate limits and 2FA'ing into 17 different tabs.
Let's take a look at each block 🧵👇

Announcing Centaur 2.0!
Centaur is frontier, agentic infrastructure that you own. Centaur is like Claude Tag, but open source and on steroids.
Centaur 2.0 can connect to everything you have access to, and can reason over it next to where you work, either in Slack, Discord, Teams or in your local Codex or Claude Code via an MCP.
But context isn't useful if it can be accessed by anyone, so we rebuilt Centaur from the ground up for security. Centaur obviously doesn't have access to secrets because we're leveraging egress proxies.
Centaur 2.0 takes that a step further enabling administrators to configure who can access what from where. This means that Centaur can have access to private information that you normally wouldn't feel comfortable giving it access to (e.g. DMs or sensitive channels and docs) but only expose it to authorized principals.
It also means you can add Centaur to external channels and leverage it as a virtual colleague that doesn't live only in your Slack, for example, but also your Slack Connect channels! This is extremely powerful as we start moving to a world where agents cross organizational boundaries.
Also in case anyone's wondering, yes we rewrote it in Rust! Centaur is now way way more stable at durably executing threads, and its workflow engine is now based on Absurd.
We have been operating Centaur since January, officially launched and Open Sourced it in May, and now we're full speed towards making it the #1 open source agentic infrastructure.
To succeed at that, I'm thrilled to welcome @mslipper to the @paradigm team who will be leading all our Applied AI work, while continuing to maintain and extend Iron Proxy as the leading secure secret access for agents. Welcome Matt, it's an honor after all these years of knowing you!
