NYSE Arca has submitted a proposal that would change how options on Bitcoin and Ethereum ETFs trade, aiming to align them with standard equity-options rules. The filing would remove a 25,000-contract position cap on certain products and broaden access to FLEX options that let traders customize terms such as strikes and expirations. It also sets eligibility thresholds for the underlying assets, including a $700m average market value requirement.

Resolv paused its protocol after a private key compromise let an attacker mint about $80M in uncollateralized USR, sparking a sharp depeg. The team said roughly 9M USR linked to the attacker has been burned, and the only confirmed loss so far is about $0.5M from redemptions processed before the pause. USR later traded near $0.19, down over 56% in 24 hours, while Resolv reported holding around $141M in assets as it prepares a redemption plan for pre-incident holders.

Grayscale filed a Form S-1 with the U.S. SEC on 20 March to register a proposed HYPE ETF linked to Hyperliquid's native asset.

BONK.fun says it has brought its site back online after a domain hijack tied to a breach at a third-party provider, with user losses now estimated at about $30,000. The team said on 20 March the attackers used social engineering against the domain service provider, leading to an unauthorized registrar transfer. BONK.fun added it will reimburse impacted users at 110% of losses, while BONK traded near $0.0000059 at the time of writing.

The U.S. CFTC has issued guidance detailing when futures commission merchants and clearinghouses may accept Bitcoin, Ethereum, and payment stablecoins as margin collateral in derivatives accounts. The framework permits use in futures, foreign futures, and cleared swaps (and allows clearinghouses to take crypto for initial margin), but keeps a ban on using crypto margin for uncleared swaps. Firms must notify the CFTC, follow enhanced reporting for the first 3 months, and apply haircuts such as a typical ~2% capital charge for payment stablecoins.

Fabric Protocol's ROBO airdrop drew scrutiny after on-chain analysis suggested one entity coordinated more than 7,000 wallets to claim about 199 million ROBO tokens, or 40% of the distribution. The allocation was estimated at roughly $8m at launch, and the token debuted on 27 February. ROBO traded near $0.025 at press time and was up about 14% since launch, though its post-launch path has been volatile.

On 18 March, the Federal Reserve kept the federal funds rate target range unchanged at 3.5%–3.75% while indicating that inflation remains too high for near-term cuts. Fresh projections point to PCE inflation at 2.7%, GDP growth of 2.4%, unemployment at 4.4%, and a federal funds rate near 3.4% in 2026, suggesting a slow and measured path to policy easing that will keep markets focused on incoming data.

On 17 March 2026, the U.S. Securities and Exchange Commission unveiled a new interpretive framework for digital assets, concluding that most crypto assets are not securities. The guidance, developed with the Commodity Futures Trading Commission, introduces a five-part asset taxonomy and clarifies how securities laws apply to activities such as staking, airdrops, mining, and wrapping. The move is intended to give issuers, builders, and investors clearer rules while Congress works on broader crypto legislation.

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. Bitrefill said it has restored most services, will cover the losses from operational capital, and has tightened security controls after the attack.
