A broad DeFi coalition started pressing U.S. universities to treat blockchain and DeFi as core finance and legal study, not side material.

📰 This Week’s Blockchain and Web3 Highlights

Nasdaq gets tokenized equities pilot approval: The SEC approved Nasdaq’s rule change, opening the door for eligible tokenized securities to trade under the same market structure as standard shares.

DeFi heads to the classroom: 1inch launched a U.S. education campaign with an open letter and a campus tour to bring DeFi and blockchain into business and law school curricula.

Stablecoin yield talks move forward: Senate negotiators and the White House reached an agreement in principle on yield language, clearing one of the tougher sticking points in the broader crypto bill.

AI audit tools still need human backup: A new re-evaluation of EVMBench found agents can help spot issues, but no agent completed end-to-end exploitation across all 110 real-world test pairs.

Visa gives bots a payment tool: Visa Crypto Labs’ new command-line tooling adds another piece to machine-driven commerce and programmable card payments.

Bitcoin gets a post-quantum testnet push: BTQ put BIP 360 into its Bitcoin Quantum testnet, giving developers a live environment for quantum-resistant transaction design.

Mastercard buys deeper into stablecoin rails: Mastercard agreed to acquire BVNK for up to $1.8 billion to more closely connect on-chain payments with fiat rails.

🔦 Tech Spotlight: Wallet-to-Card Rails Explained

Wallet-to-card rails let someone hold value in a wallet and pay with a normal card tap, while the merchant still receives a standard card payment. The wallet balance funds the purchase in the background.

That matters because it cuts out the old routine of bridging, selling, withdrawing, and waiting before spending. Visa says Bridge-enabled stablecoin-linked cards are live in 18 countries and planned for more than 100 by year-end. MetaMask says its card works anywhere Mastercard is accepted.

Takeaway: The harder moat may sit in the rail layer itself, where funding, compliance, settlement, and merchant acceptance come together. Mastercard’s BVNK deal makes that point well.

📊 Chart of the Week: Tokenized Assets Hit $25B

This week’s chart tracks a market that has crossed $25B. Treasury products still carry the largest weight, but other tokenized categories are no longer small side stories.

Our read is that this buildout is starting to look less like a one-cycle crypto trade and more like steady financial infrastructure work. Direct token exposure tells one part of the story. The other part sits in issuance, funding, settlement, custody, and payment connectivity. That is where the rail layer lives.

That wraps up Edition #104. Nasdaq moved tokenized equities closer to real market use. DeFi groups took their pitch to U.S. campuses. Stablecoin yield talks finally showed forward motion. Visa added to the machine-payments stack, BTQ gave the quantum debate a live testnet angle, and Mastercard wrote a very large check for stablecoin infrastructure.

✅ Trivia Answer: A) Verifiable credential

A verifiable credential lets someone prove a claim, such as age, education, or membership, without handing over every piece of personal data.

We’ll be back next week with another sharp set of reads and ideas from across blockchain and Web3.
