Exiting ~7,000 Validators: A Case Study in Optimizing Ethereum Validator Exits

In December 2025, A41 announced their decision to wind down validator operations across all networks and conclude its participation as a Lido Curated Node Operator.

Contributors optimized their exit to minimise protocol reward loss under a constrained timeline.

This case study presents the approach, operational execution, and lessons learned from the exit.

Today we announced an actively managed Bitcoin derivatives program facilitated by Kraken and Bitwise. The program is designed to generate volatility income and hedge downside risk.

1/ EthCC was our 2nd forum covering data insights, AI, ePBS, new EIPs, world-renowned macro Researchers, issuance, ZK & builders, privacy, and a fireside covering Ethereum. We hope the community enjoys the videos below. The ticker is ETH. 🧵👇

The past few days have been intense, but I wanted to give some updates as we continue to work on this. Our priority is our users, and every decision we are making is aimed at an orderly return to normal market conditions and the best possible outcome for everyone involved.

Working around the clock, the team has made progress on multiple paths forward with several partners. The Arbitrum Security Council also recovered $70 million in ETH, which could meaningfully reduce the potential exposure, and multiple discussions and solutions are being considered. I am confident we will move towards a strong resolution.

Reviewing what happened and learning from it matters. But pointing fingers is not something that gets us to the other side of this.

Every bit of my energy right now is focused on the outcome for Aave users and the protocol. Aave has been my life's work, and this is an important moment for DeFi as much as it is for Aave. I am deeply grateful for the support and collaboration we have received from builders and partners across the industry.

We’ll get through this together and we’ll continue to publish updates on @aave as they happen.

[Bitwise @Bitwise]

A lot of reasons to love the 🔺 ecosystem. Thanks for sharing!

Today I'm releasing https://t.co/8JYBYUbyLq

Since @AttestantIO released Vouch and Dirk in 2020, they have respectively become the industry standard multi-beacon validator client and bls threshold signer implementation.

Now you can use Dirk with any Validator Client.

1/ In Cannes, Blockspace Forum held its second workshop, attended by 32 teams representing >95% of out-of-protocol blocks. We’ve summarized the key outcomes and concepts that surfaced. Thank you to everyone who contributed. The ticker is ETH. 🧵👇

After 5 years on the @ethereumfndn leadership team, I’ve decided to step away and pass the torch. I made this decision in early March, and will wrap up my work at the end of April. I’ve made no plans for the future, other than taking a long break to reset and spending time with my family & friends.

Working for Ethereum at the Ethereum Foundation has been a great honour. I’m proud to have worked with great people inside and outside of the EF, and proud of what our community has accomplished together. And I’m grateful to have worked with @aerugoettinea, @dannyryan, @hwwonx, @tkstanczak, @tjuliang, @VitalikButerin, and @AyaMiyagotchi on the leadership team over the years. We share a vision and a set of values that mean I will always be your ally and your friend.

This journey has been a gift. I have had the rare privilege of seeing up close how small teams of great people can do the impossible. It has changed how I see the world and my place in it. We do not need to accept the world as it is, or where we fear it is going. That is not hope, it is definite: I have seen the proof.

The Ethereum ecosystem has reliably done things the world told us was impossible. It is easy to forget how much real fear and doubt there was that Ethereum would never launch, that DeFi would never work, or that Proof of Stake would never ship. The lesson is not that our success was guaranteed and the doubters are always wrong, but that truly wicked problems can be overcome when great people make an extraordinary effort. You must make an extraordinary effort.

appreciation for how well-run @ethcc is:
⤷ self-serve ticket kiosks (no lines)
⤷ childcare (wow)
⤷ coat and luggage checks
⤷ zero wifi issues
⤷ quick security in venue and also very safe around town!
⤷ side event venues all <6 minutes walking distance
⤷ talks ran on-time, didn't see any AV issues
⤷ stellar weather (i assume they ordered this in advance)

the industry vibes could literally be rock bottom but ethcc in cannes would still be immaculate because of location and how well this thing is run

kudos @jdetychey & @bettina_boon

[Bitwise @Bitwise]

That's a wrap on @EthCC!

@hongkim__ shared how Bitwise is raising the bar for Ethereum staking. As more of the world’s largest asset managers and institutions enter the space, the need for reliable, institutional-grade infrastructure is only growing.

[Bitwise @Bitwise]

Bitwise is on the ground at @EthCC 👀

Lots to talk about — find us here. Reach out to @alinadel5 to set up time to connect.

[Potuz @potuz_eth]

Ethereum is "slow to finalize" they say, but in normal conditions in fact we are certain that blocks will be final even before the next block arrives! Expect ultra fast trustless deposits soon.

[ansgar.eth @adietrichs]

Ignore the noise. Ethereum is shipping.

This one I am very excited about - the team working on it has done an amazing job:

When an Ethereum block is created, validators immediately start voting. Now, it is possible to use those votes to confirm blocks in a single slot (~13s)!

[Hunter Horsley @HHorsley]

There are two types of companies / projects in crypto —

1. One-cycle

2. Multi-cycle

Admire all who build / contribute, and especially admire those who endure to be multi-cycle players.

We’re now entering the next cycle.

[Hunter Horsley @HHorsley]

Great to see from BlackRock.

High conviction on Ethereum, and exciting to see an option that incorporates staking.

Crypto is becoming a mainstream asset class —

[James Seyffart @JSeyff]

As we already knew. $ETHB will have @coinbase as its custodian and staking provider. The list of approved validators is short though -- just Figment, @galaxyhq, and Attestant.

Notably, Attestant was acquired by @Bitwise and is rebranding to 'Bitwise Onchain solutions'

[build the bridge @bitkite]

Respect @hongkim__ and the entire @Bitwise team

[Chris Berry @Bez625]

Even though CT got this slightly incorrect, we're still incredibly proud that the EF chose to use our products.

Thanks to @nixorokish for the clarification ❤️

[nixo.eth ����🔊🥐 @nixorokish]

this is wrong but I understand how you got there - the EF is solo staking, using @AttestantIO 's free and open source software to do so. Attestant was acquired by @Bitwise , so they're the maintainers of the software.

They are not running infrastructure for EF treasury staking - the EF is running their own infra

[Hunter Horsley @HHorsley]

Proud of this —

Bitwise staking team ("Bitwise Onchain Solutions") does fantastic work.

Delighted to both help investors invest in networks, and participate in them.

[Devcon 8 | Mumbai, India 🇮🇳 @EFDevcon]

Let's start the countdown: 1 week to @ETHMumbai!

We’re not just participating.
We’re bringing something with us.

Any guesses? 👀 🎁
