BlackRock’s BUIDL Move To Arbitrum Shows Tokenized Treasuries Are Leaving Ethereum Mainnet Only Mode

BlackRock has expanded its BUIDL tokenized treasury fund beyond the Ethereum mainnet by integrating with the Arbitrum network. This strategic move signals a shift for institutional-grade financial products, which are increasingly prioritizing scalability and cost-efficiency alongside security. By leveraging Layer-2 solutions, BlackRock aims to overcome the high transaction costs associated with the Ethereum mainnet, making tokenized assets more accessible for broader distribution. This expansion highlights that major asset managers are moving past experimental phases to treat tokenization as essential, scalable infrastructure. The integration serves as a significant endorsement for the Arbitrum ecosystem and the broader Ethereum Layer-2 landscape. For the RWA market, this development confirms that tokenized treasuries are evolving into a mature product category rather than remaining a niche crypto-native concept. Ultimately, the transition to multi-chain deployment demonstrates that institutional players are actively optimizing their technical stacks to support the long-term growth of real-world assets.
