Aligned is the Ethereum migration stack. One suite — rollups, wallets, interoperability, and ZK verification — for businesses building real financial products on Ethereum. Aligned token sale is coming soon, join the whitelist.

The most decentralised staking protocol just got a big upgrade.

Saturn One improves Rocket Pool's capital efficiency, helping node operators to stake with less ETH, while increasing capacity for liquid stakers. A withdrawal buffer boosts rETH price stability and enables faster exits, while MEGAPOOL validators reduce bond requirements and increase yield for operators.

The upgrade also introduces a fee switch for the RPL token, transforming it into an ETH-accrual token that captures protocol revenue instead of relying on inflationary rewards. Saturn One strengthens Rocket Pool’s decentralised staking model, improves economics for rETH holders, node operators, and RPL stakers, and lays the groundwork for future upgrades.

Now is the best time to stake your ETH with Rocket Pool.

The DeFi Exploit That Exposed a Bigger Problem

In this episode of The Defiant Podcast, Cami sits down with Omer Goldberg, founder of Chaos Labs.

A new DeFi exploit triggered millions in losses, but the deeper story is about risk. Goldberg explains how the attack unfolded, why the damage spread across lending markets, what vault curators got wrong, and whether DeFi is truly ready for mainstream adoption.

Today’s Big Story

I Didn't Know Anything About Quantum Risk to Crypto. Here's What I Learned.

Two research papers dropped this week, one from Google, one from a Caltech team, and my timeline filled with people losing their minds about quantum computers breaking Bitcoin. How much of it is true and how much is FUD?

To find out, I spoke with Alex Pruden, co-founder and CEO of Project 11, a company at the intersection of cryptography and quantum computing. I went in skeptical and came out genuinely unsettled. Here's what I learned (watch out for the full interview on The Defiant podcast in the next couple of days. Subscribe: LINK)

The threat is real, and these papers made it more urgent

The two papers significantly shrunk the estimated resources needed to break the cryptography underlying essentially every blockchain. Google reduced the operations required to run Shor's algorithm — the quantum attack on public key cryptography — from tens of billions down to roughly seven million. The Caltech team reduced the physical qubits needed to just 10,000. For context, a quantum computer at Caltech already has 6,000.

The good news is, these are still theoretical constructions, not existing machines.

Why this is existential

Alex made the point that the attack would crack the core concept of ownership in crypto. When you "own" Bitcoin or ETH, you hold a private key, which you don’t disclose, and a public key. A quantum computer running Shor's algorithm can take your public key, which is visible on-chain the moment you transact, and reverse-engineer your private key.

"If I have a quantum computer," Alex told me, "in some sense I own everyone's crypto."

The underlying target is ECDSA, the elliptic curve digital signature algorithm that is the common cryptographic foundation for virtually every blockchain. Bitcoin and Ethereum use the exact same curve. This is everyone's problem.

The timeline is uncertain

Project 11's models put a 50/50 chance of a cryptographically relevant quantum computer around 2032, with a possible floor of 2029. Google is migrating its own cryptography by 2029. The NSA has given U.S. agencies a hard deadline of 2030.

But we don't know what Google or the NSA actually know. Quantum capability is exactly the kind of advance that labs and nation-states have every incentive to keep quiet; after all, they could be trying to read adversary communications or quietly recover Satoshi's Bitcoin.

Alex argued that even if there's only a 15–20% chance this hits on the aggressive timeline, the consequences of being unprepared are catastrophic enough to act now. "I wear a seatbelt not because I think there's a 15% chance I'll get in a car wreck."

Solutions exist, but none are easy

Post-quantum cryptography has been in development for decades, and the U.S. standardized the first replacement algorithms for ECDSA last year. Some can even be implemented in Ethereum smart contract wallets today, before any protocol-level upgrade. Project 11 is launching a post-quantum vault for exactly this purpose in the coming weeks.

The catch: the new algorithms are a meaningful downgrade in other ways. They need larger signatures, are missing multi-sig and MPC support, and have slower performance. Some won't even fit in older Ledger hardware wallets. Every bridge, wallet, and piece of infrastructure under MetaMask, Coinbase, and Anchorage would need to be rebuilt. This is Ethereum-merge-scale work, across every chain, against an uncertain deadline.

According to Alex, of all the major ecosystems, the Ethereum Foundation is furthest ahead with post-quantum now formally on the roadmap. But no chain has done enough.

The first step in solving a problem is admitting you have one. This week's papers seem to have finally forced that admission. Better late than never, but only if we don't stop there.

With love,

Drift Protocol Vault Loses $270 Million in Potential Exploit

Solana-based perpetuals exchange Drift Protocol has suffered a series of large-scale outflows, with roughly $270 million in assets drained from the protocol's vault address in a matter of minutes.

Why it matters: The losses account for more than half of the protocol’s TVL.

Franklin Templeton Launches Dedicated 'Franklin Crypto' Division

Franklin Templeton has agreed to acquire 250 Digital, a crypto investment firm spun out of CoinFund in January, establishing a dedicated division called Franklin Crypto aimed at institutional investors.

Why it matters: The acquisition is the latest move in Franklin Templeton's deepening commitment to digital assets, which dates back to the formation of its digital assets team in 2018.

Bitcoin Reclaims $68,000 as Iran Ceasefire Hopes Fuel Risk-On Rally

Crypto markets started April in the green, snapping a bruising first quarter with a relief rally that continued into Wednesday as hopes of geopolitical de-escalation lifted risk assets

Why it matters: March marked the first positive monthly inflow for Bitcoin ETFs since October, reversing four consecutive months of outflows.
