The landscape of digital finance reached a significant milestone on September 16, 2026, as Circle officially launched the public mainnet for Arc, a Layer 1 blockchain designed specifically for institutional-grade financial transactions. This rollout is anchored by a founding validator cohort that includes the Depository Trust and Clearing Corporation, BlackRock, and Visa, signaling a major shift toward regulated, on-chain settlement for real-world assets [5] [7]. By integrating the depository trust and clearing corporation dtcc into the core validation layer, the network aims to bridge the gap between traditional clearing infrastructure and decentralized finance (DeFi) protocols [5] [11].
The Role of the Depository Trust and Clearing Corp in On-Chain Settlement
The participation of the depository trust and clearing corp as a founding validator marks a pivotal moment for the tokenization of traditional securities. The DTCC, which holds custody over more than $114 trillion in assets through its primary subsidiary, is utilizing this partnership to explore secondary liquidity and borrowing mechanisms for tokenized real-world assets (RWAs) [11]. While the Arc mainnet is now live, the DTCC’s specific capability to tokenize assets held in its custody is not scheduled to begin until the second half of 2027 [5].
Arc distinguishes itself from permissionless blockchains by utilizing a proof-of-authority consensus model, where blocks are produced by a fixed set of regulated financial institutions rather than an open market [7]. This cohort includes asset managers like BlackRock, market infrastructure providers like ICE, and payment giants such as Mastercard and Visa [5]. The network uses USDC as its native gas token, ensuring that transaction fees remain denominated in a stable dollar value rather than a volatile crypto asset [7]. Circle has documented a base fee target of approximately $0.01 per transaction, with sub-second finality and throughput exceeding 3,000 transactions per second [7].
Institutional Credit and Liquidity Integration
Beyond simple asset issuance, the Arc ecosystem is launching with established DeFi credit infrastructure. Aave Labs and Morpho are providing lending markets on the chain from day one [7]. Aave is deploying its V4 architecture on Arc, supported by risk oversight from firms like Bitwise and Gauntlet [7]. This integration allows institutions to move beyond mere issuance and into active credit markets, where tokenized assets can be used as collateral for borrowing [4].
Expanding the Reach of Tokenized Equities
The launch of Arc coincides with a broader surge in the tokenized equity sector, which has recently reached a total value of $2.3 billion [17]. Standard Chartered has initiated coverage on Arbitrum (ARB), setting a long-term price target of $10.00 by 2030, driven largely by the growth of tokenization and licensing deals with traditional finance firms like Robinhood [16]. The bank forecasts that tokenized assets, including stablecoins and RWAs, could grow to $4 trillion by the end of 2028 [16].
Retail access to these assets is also expanding. Bitget Wallet recently integrated Reality’s tokenized U.S. stocks and ETFs, offering exposure to over 1,700 assets including rNVDA and rAAPL to its user base of 100 million [17]. These tokens are backed one-to-one by shares held at Alpaca Securities, a FINRA-registered broker-dealer [17]. Similarly, Kraken has introduced "xStocks" vaults, allowing eligible clients to earn variable yields (estimated at 1.8% to 2% APY) by using tokenized equities as collateral in Solana-based lending markets like Kamino [22].
Data Infrastructure and Market Connectivity
As tokenized markets move toward 24/7 operations, the demand for institutional-grade data has intensified. S&P Global recently led a strategic investment that extended Kaiko’s Series B funding to $110 million [15] [21]. This capital is intended to build the data infrastructure required for round-the-clock tokenized markets, covering everything from Treasury bills to private equity [21]. The investment follows the launch of the S&P Kaiko Digital Asset Indices, a suite of over 4,000 rates and indices designed to provide standardized pricing for the digital asset class [15].
Connectivity between centralized exchanges and these new on-chain environments is also being established. KuCoin has integrated Arc at launch, allowing users to transfer USDC directly to the network to access its emerging ecosystem of applications [6]. Meanwhile, Binance has expanded the utility of tokenized assets by enabling CEA Industries' BNCB bStocks token as margin collateral for eligible VIP users, further blurring the lines between spot trading and sophisticated credit strategies [1].
What to watch next: The market will be monitoring the first wave of institutional deployments on Arc, specifically BlackRock’s BUIDL fund, and the progress of the Depository Trust and Clearing Corporation as it works toward its 2027 tokenization roadmap. Additionally, the ongoing debate over Uniswap v4 hooks and the fragmentation of account abstraction standards between Base and Ethereum will likely dictate how seamlessly retail users can interact with these new institutional rails [10] [20].
