The third week of March marked a major acceleration in the convergence between traditional finance and blockchain-based infrastructure.

The SEC approved Nasdaq’s pilot for tokenized equity trading, Mastercard moved to acquire stablecoin infrastructure firm BVNK for up to $1.8 billion, and Hyperliquid launched officially licensed S&P 500 perpetuals onchain. At the same time, regulators continued building clearer market structure for crypto.

But the week also exposed the industry’s fault lines, from BlockFills filing for Chapter 11 to a nearly $50 million Aave execution failure that triggered new DeFi guardrails.

In this episode:

• Nasdaq gets approval for tokenized equities pilot

• Mastercard moves to acquire BVNK in up to $1.8B deal

• Hyperliquid launches licensed S&P 500 perpetuals

• SEC issues new crypto interpretive guidance

• Phantom receives CFTC no-action relief

• BlockFills files for Chapter 11 as Aave rolls out Shield

Traditional finance is moving onchain fast — but crypto’s risk layer is still being stress-tested.
