I'm setting up my first Ethereum validator with the help of @agustincit0x and the amazing @ethStaker community docs.
Here’s how it’s going so far: 🧵👇

cant believe I’m witnessing my first event as part of the @ETHGlobal team. so many emotions rn
⚠️ Scam alert: Fake Telegram accounts are impersonating me and Chainstack team, using our photos and listing our handles in their bios.
I will never DM you first on Telegram, ask for your seed phrase or private keys, or ask you to send funds.
If someone reaches out, don’t engage.
Report and block them, and verify with us here.

As a founder and CTO, I take the security and privacy of our customers seriously. @ChainstackHQ recently experienced an attack that may have exposed customer information and credentials.
Please read our report and take the recommended steps. Thank you for your trust 🙏🏼
We detected and contained the attack, and are now focused on hardening our systems. Our findings indicate it was part of a large-scale, AI-powered attack campaign reported in late October.
Full details and updates are in our incident report.
The security and reliability of our systems remain our top priorities, and we are taking further steps to strengthen our safeguards. Thank you for your continued trust.

Crypto is becoming a battlefield in a global economic war and state-backed actors have already shown they can weaponize this industry to fund their operations.
If this @binance incident is another chapter in that story, we may be witnessing a major escalation of a conflict that’s been unfolding in the shadows for years.
🚨 UPDATE:
If confirmed, Binance's reported $5.7 billion hack would be the largest in crypto history, surpassing Bybit's $1.5 billion hack in 2025 and Ronin Network's $625 million hack in 2022.

Watching this come together over the past weeks has been wild. Huge effort from the whole @ChainstackHQ infra team to launch on time and stay ahead of the market.
Proud to be part of it 💙

Con @agustincit0x cubrimos el hack de @KelpDAO y @LayerZero_Core en @nadievalidoesto💡
Si te interesa entender dónde estuvo la vulnerabilidad y cómo fue el timeline de los hechos, escuchate este resumen 👇
Dos nodos comprometidos🚩
Un DDoS para silenciar al resto. Y 277M de dólares saliendo en segundos 💸
Así fue el hack de @KelpDAO x @LayerZero_Core 🧵
y te lo contamos con @agustincit0x

We closed an amazing week in Miami with the @ChainstackHQ team 🌴
It’s so nice to see how strong the ecosystem still is. Great catching up with old friends and meeting new builders pushing the space forward.
We’re building the future crypto and RPC infra here 🚀

We actually proposed a solution for this to @ethereumfndn back in 2023: @scidomains.
The idea was simple, link smart contracts to DNS domains and add an alerting system for suspicious changes.
Unfortunately, it didn’t get their attention at the time.
Hoping users stay safe and revoke access ASAP.

🚨🚨
UPDATE: CoW Swap experienced a DNS hijacking at 14:54 UTC (approximately 90 minutes ago).
The CoW Protocol backend and APIs were not impacted, but we have paused them temporarily as a precaution.
We are now actively working to resolve the situation. Please continue to refrain from using swap dot cow dot fi until we confirm that it is safe to use.
Two days in and already met some wonderful partners🧙♂️
Kicking off day 3 at @EthereumDenver, and ready to keep spreading the node magic at the Main Event 🛠️💙
And last but not least - the final member of our @EthereumDenver team, our Wizard of Nodes: Santiago @defirmware 🧙♂️
If you’re building and want to go deeper into node configuration or performance tuning, talk to him in Denver.
See you there! 🏔️

If you’re in Denver this week, message me!😀
Happy to chat about your RPC node infrastructure and how we can help you take it to the next level with @ChainstackHQ 💙🛠️
We’ll be at @EthereumDenver in February 🏔️
Talking Ethereum RPC in production — latency, throughput, scaling trade-offs, and what usually breaks once traffic ramps up 💬
Catch @callan_clarke, @maguiyapi, and @defirmware if you’re building on Ethereum or planning your next infra move 🛠️
Stoked to be in Denver for @EthereumDenver 2026. Hit me up if you are around and want to chat with the Wizard of Nodes himself 🧙♂️

My tg account is still compromised and since @telegram has the worst support I doubt I’ll ever recover it.
If you’re getting this cringe message, it’s deffo not me:
“Hi [name], It's been a while. how are you doing ? would you have some time this or next week to connect?”
🫠🫠
important notice: I’ve been hacked on Telegram 🚨
to everyone I’ve interacted with before: if you see any new messages, please don’t reply, it’s definitely not me.
if you want to reach out, feel free to DM me here or contact anyone at Certora so they can share my new handle with you :)
a small bump in the road to start the new year and a reminder that we should never let our guard down
stay safe friends
I’m happy to share that I’ve joined @ChainstackHQ 🛠️💙 as an Account Manager 🚀
I’m grateful for the opportunity to work with such a strong team in the blockchain infrastructure space, and I’m genuinely excited about this new chapter.
If you’re curious about scaling your app with unlimited RPC requests and geo balanced, reliable blockchain infra, don’t hesitate to reach out.
Thanks to everyone who supported me along the way ♥️

Thread rapidíto que armamos con @agustincit0x sobre la historia de Uniswap y las decisiones técnicas que lo llevaron a ser el AMM #1 👇
🦄 @Uniswap: la historia del exchange que cambió DeFi para siempre
@UniswapFND nació como una idea simple: permitir intercambiar tokens sin intermediarios, sin permisos y sin order books.
Y terminó redefiniendo cómo funciona el trading onchain. En este video y thread repasamos su historia.

Con @agustincit0x explicamos qué es el consenso y cómo ayuda a definir la historia en las blockchains.
Si te interesa entender cómo funciona crypto desde las bases, te recomiendo seguirnos en @nadievalidoesto💪
El consenso en blockchain no depende de una autoridad central 🏦
A diferencia de un banco donde una base de datos decide todo, acá la red completa 🌐 valida cada bloque mediante reglas criptográficas y validadores alineados.
Esto crea confianza distribuida y transparencia total👇

El double spending es un intento de gastar la misma moneda digital más de una vez 🖨️
En sistemas tradicionales esto lo controla un servidor central 🏦 que valida cada pago.
En redes descentralizadas como Ethereum no existe ese servidor, así que la red necesita un mecanismo propio para asegurarse de que una transacción no se pueda duplicar.
Cómo lo resuelve Ethereum?👇
