Without the BRCA, Clarity becomes bill that helps the largest and most regulated businesses while leaving the builders of free and open infrastructure out in the cold. https://t.co/CgrbP3eGTM

It's finally happening!

SEAL Certifications are now open for business. 🎉

A vulnerability has been found in two Zodiac modules: Roles Modifier v2 and Delay Modifier v1.1.0.
Please check carefully

@MilkRoad It has been unfrozen, the court admitted it was unwarranted. See here https://t.co/ygAnxo2Vws

I'm not Catholic but this is 100% right and I'm glad a religious leader is saying it. There's more to fear from people who think we're building AI gods than there is from AI itself.

@maraoz Official post from @OpenZeppelin confirming the above

https://t.co/FYykg6RCF4

[OpenZeppelin @OpenZeppelin]

Recent posts by Manuel Aráoz on AI and DeFi security have been widely circulated, and customers have asked whether they reflect OpenZeppelin's position. They do not.

Manuel co-founded OpenZeppelin and served as the company’s CTO until 2019 when he left the company.

[Michael Lewellen @LewellenMichael]

@maraoz is an incredibly smart guy but stepped away from OpenZeppelin in 2019 with little engagement in smart contract security since then, to my knowledge.

Take his comments with a hefty serving of salt. AI is creating new attacks vectors but also new defenses. The war for DeFi security continues and isn't lost by any means.

[Manuel Aráoz @maraoz]

PSA: I now consider *all* of DeFi unsafe.

Coding agents are superhuman at finding vulnerabilities, and smart contract security is too asymmetric: defenders need to fix every bug while attackers need just one exploit to steal funds.

@cooper_kunz @sadbryce Ty ser! 🙏

[Peter Van Valkenburgh @valkenburgh]

Senator Cortez-Masto's attempt to narrow the BRCA is substantial. He proposal would fail to protect nodes, miners, and smart contract software developers. All of these are neutral infrastructure providers. They make the tech work. 1/

[Peter Van Valkenburgh @valkenburgh]

Around $3 Trillion dollars were laundered through banks in 2025 despite the warrantless surveillance regimes they facilitate for governments. And they want you to think that people making peer-to-peer transactions on chain are the problem that needs to be outlawed.

[Michael Lewellen @LewellenMichael]

Excited to join @StabledCompany on Turnkey Unlocked this week!

[Turnkey 🔑 @turnkeyhq]

[Peter Van Valkenburgh @valkenburgh]

Senator Lummis, her staff, and others have worked tirelessly to preserve the BRCA in these negotiations and Coin Center is incredibly grateful.

We're not there yet but I am optimistic that we can pass into law real protections for crypto and privacy tech developers.

[Stabled @StabledCompany]

We are looking forward to talking with @LewellenMichael and @turnkeyhq on the future of cross-border payments.

Tune in May 15th at 1pm EST

ICYMI: @lightspark launched Grid Global Accounts last week.

Embedded wallets power self-custody, scoped agent delegation, and cross-chain interoperability built into the account layer.

Important update regarding Comet markets

After coordinating with the Kelp and Aave teams to avoid disrupting broader DeFi recovery efforts, the Ethereum WETH and wstETH Comet markets are now unpaused.

A temporary pause may still be required during the liquidation window for the exploit-related position, depending on the timing of Kelp’s rsETH unfreeze. Because this process involves multiple parties, the exact timing remains uncertain.

We will share further updates as they are confirmed.
