4D Labs, a real-world embodied data layer protocol for physical AI, has received investment from YZi Labs through EASY Residency Season 2, according to an official announcement cited by BlockBeats on Sept. 11. Publicly available project information describes 4D Labs as an infrastructure company for spatial intelligence foundation models operating at the intersection of AI, 3D and Web3. The company says its core mission is to address what it calls the most fundamental bottleneck of the spatial computing era: the lack of high-quality 3D data that can scale, be verified, and carry provable ownership. The announcement did not disclose the size of the investment or other deal terms.

A wide set of crypto, policy, payments and market developments surfaced between Sept. 1 and Sept. 2. In the U.S., the Securities and Exchange Commission proposed updating registered transfer-agent rules for the first time in decades to reflect blockchain-based securities records and tokenization. At the international level, a G20 chair statement released by U.S. Treasury Secretary Scott Bessent said finance ministers and central bank governors recognized the growth potential of digital assets and pledged to create a clear path for “responsible innovation.” Separately, 21 global financial institutions said they plan to form a new company to issue fully reserve-backed stablecoins, starting with a U.S. dollar product and targeting launch in the first half of 2027. Market activity also stayed busy: U.S. spot Bitcoin ETFs pulled in about $3.5 billion in August, Felix Pago raised $200 million in Series B financing, Ethena rolled out a test version of Ethena Pay on Avalanche, and Bitfinex Securities listed five tokenized products tied to listed Bitcoin treasury companies. On the enforcement and security side, TRM Labs’ $95 million U.S. Homeland Security contract drew a lawsuit from Chainalysis, while Full Sail said it would wind down after a Switchboard oracle incident hit Virtue Money.
