Moody’s Ratings has introduced its Token Integration Engine to distribute credit analysis on the Canton Network, enabling permissioned access to its traditional ratings data within blockchain-based financial workflows. The system is aimed at institutional finance, keeps issuer-controlled permissions under Moody’s governance framework, and is initially live on Canton with plans to expand to other chains and asset types. This rollout adds to growing institutional use of Canton for tokenized funds, collateral markets, settlement infrastructure and bank-issued deposit tokens.

A Buenos Aires court has ordered a nationwide block on prediction market platform Polymarket in Argentina, citing unlicensed gambling activity and weak user controls. Judge Susana Parada instructed telecom providers, as well as Google and Apple, to restrict access to the website and app after an investigation found crypto- and card-based betting without proper identity or age checks. The case followed a complaint from local lottery authorities and coincided with scrutiny over Polymarket activity around the release of February inflation data.

On 1 March 2026, Bitrefill reported a cyber incident in which attackers drained funds from its hot wallets and accessed parts of its infrastructure. The breach involved misuse of its gift card supply system and exposed around 18,500 purchase records, including email and crypto payment addresses.

On March 17, 2026, the Ethereum Foundation introduced a fellowship-style grants program offering $24,000 to selected PhD students. Between 9 and 10 fellows will receive one-year funding to support Ethereum-related academic research across fields like economics, public policy, computer science, and sociology, with proposals due by April 1 at 23:59 UTC.

On March 17, 2026, William M. Peaster explored how Ethereum-based infrastructure could support an experimental zine model called Combinatoria. The concept uses a Bread Cooperative-style yield vault and tools like Sablier and Splits to stream onchain income to 5–10 curated writers each epoch. A hypothetical $100,000 in deposits generating $6,000 in annual yield would pay writers more than many traditional literary magazines, without requiring patrons to spend their principal. The piece argues that such onchain assemblages could provide financial sustainability and independence for niche cultural communities beyond just this example.

On March 17, 2026, non-custodial exchange ChangeNOW introduced Private Send, a NOW Wallet feature that breaks direct links between sender and recipient addresses on public blockchains.

It supports most assets in NOW Wallet, follows existing AML and geographic rules, and targets users seeking added privacy without extra registration or apps.

On Tuesday, the U.S. Commodity Futures Trading Commission's Market Participants Division issued a no-action letter to crypto wallet provider Phantom Technologies, allowing it to operate in certain ways without registering as a broker.

The decision is among the first no-action responses for a crypto firm under CFTC Chair Michael Selig, who continues to assert the agency's authority over prediction markets while coordinating with the SEC.
