Alabama Gov. Kay Ivey signed SB 277 into law on Wednesday, creating a legal framework for DAO-like decentralized nonprofit organizations. The measure says members generally are not personally liable for the association's activities, and it is expected to take full effect on Oct. 1, 2026.

Coinbase Chief Legal Officer Paul Grewal said the U.S. Clarity Act is "very close" to an agreement on how stablecoin yield should be handled, following a Wednesday interview. He argued there is no evidence that allowing yield on idle stablecoin balances would trigger bank deposit flight and said the yield debate should not be mixed with other issues banks are facing. Coinbase shares closed down 0.9% on Wednesday at $172.99 after falling 50% over the past six months.

PeckShield said crypto hacks and exploits led to $52 million in losses across 20 major incidents in March. The firm noted the total was up 96% from $26.5 million in February, with the largest share tied to a Resolv Labs exploit that drained over $25 million in USR stablecoins. It also warned that knock-on effects can spread to connected DeFi venues when a compromised asset sharply devalues.

KB Kookmin Card said Tuesday it will work with Avalanche to develop a hybrid stablecoin payment model designed for use with existing credit cards. The company plans to build the system on a public blockchain and, with OpenAsset, cover top-ups, payments, and settlement, while prioritizing wallet stablecoin balances before charging any remainder to credit.

Google Research said a new estimate shows the quantum resources needed to break the cryptography used by many blockchains have dropped by about 20x, potentially bringing the risk closer than earlier projections. The team argued faster execution could enable "on-spend" attacks against Bitcoin transactions during the roughly 10-minute block window, and pointed to a 2029 goal for migrating to post-quantum cryptography.

GameStop's latest 10-K filing says the company did not sell the 4,709 BTC it bought last year, instead pledging it as collateral with Coinbase Credit.

Coinbase has again declined to back the latest Clarity Act draft, focusing its objections on language that would bar platforms from paying yield or rewards on stablecoin balances. A bipartisan version circulated Monday would also curb incentives by limiting access to transaction-size data used to calculate rewards.
