Hello Pectra: Updating our Validator Fleet

Endaoment COO, Zach Bronstein, shares how Pectra, the latest Ethereum network upgrade, brings a new dimension to our validator operations.

When we spun up our first five validators in mid-2023, we weren’t just securing Ethereum—we were building a self-funding engine for our nonprofit. Every gwei of yield we earn goes right back into powering Endaoment’s mission. Pectra—the 16th Ethereum network upgrade, that went live on May 7, 2025—takes that vision to the next level and unlocks new functionality for validator operators and Ethereum users alike. Let’s dive in!

Pectra in a Nutshell

Pectra marries the Prague execution-layer hard fork with the Electra consensus-layer upgrade. It’s Ethereum’s biggest upgrade since Dencun and brings 11 EIPs. But for anyone running validators, the headline feature is:

• EIP-7251: max effective balance jumps from 32 ETH → 2,048 ETH, so each node can carry 64× more stake, unlocking compounding rewards for validator operators, and reducing operational overhead for both validator operators and Ethereum generally.

What This Means for Us

A Lean Validator Fleet
Fewer validators = smaller activation/exit queues, less monitoring of different validators, [potential] lower client-diversity risk, and perhaps most importantly, lowering overall overhead for the Ethereum blockchain. Any time that consensus needs to be reached, that is determined by ETH balance. If each validator can have 64x as much ETH as before, fewer validators will be needed to achieve consensus but represent the same share of ETH.

Automatic Compounding
Switching to 0x02 withdrawal credentials allows rewards to auto-restake, compounding rewards and extending Endaoment’s runway as a result.

Supercharging Ethereum’s L1 Scalability

Pectra isn’t only about staking—Ethereum’s L1 is getting turbo-charged for rollups, too. EIP-7691 doubles blob capacity (target blobs per block 3 → 6; max 6 → 9), effectively doubling L2 data throughput and slashing Layer-2 fees and congestion.

Together, bigger validators and expanded blobspace demonstrate that Ethereum is doubling down on both security and scalability.

How We Pectra-fied Our Fleet

Credential Upgrade (0x02)
We converted validator 655226 to 0x02 (compounding) withdrawal credentials.
TX: 0xcf1ab870359978855097664d5b12195ebc255cc68db1e2db639e7414be1ab0e0

Consolidation
We exited one 32 ETH node and topped up the 0x02 validator to absorb its stake.
TX: 0x73f7045b45684a3b749d6d47a8b2d09bf54f7d8bec7cc73124122c26dc92ff6b

Top-Up
We then deposited spare ETH (from 3 other validators that had previously exited, plus some additional ETH) under Pectra’s new 2,048 ETH cap.

Pectra lets us run bigger, fewer (just 1!), and self-compounding validators while Ethereum doubles down on both L1 and L2 scaling. If you’re validating, now’s the moment to consolidate, compound, and help drive both network security and rollup-centric scalability, just like we did at Endaoment, while also increasing your rewards!

If this is a path you plan to take, a couple of important resources you may want (many are already linked above):

• Information about all Pectra included EIPs

• Taking validator actions using the Launchpad UI

• Pectra Dashboard (also can be used for tracking an individual validator’s consolidation related activity)

• And of course, our updated open source Validator guide
