Biotech firm NovaBay said it will rename itself Stablecoin Development Corporation and enter digital assets, sending shares up about 19% to around $1.40. The company plans to change its ticker from NBY to SDEV effective April 3 and disclosed holdings of about 2.06 billion SKY tokens valued near $150 million plus 26.6 million staking rewards.

Bitmine, led by Tom Lee, bought an additional 65,341 Ether, taking its total position to more than 4.66 million ETH. The company's Ethereum treasury is now valued at about $10 billion and accounts for roughly 3.86% of ETH's circulating supply.

USR, an overcollateralized stablecoin backed natively by ETH and issued via the Resolv protocol, broke its peg on March 22 after an attacker minted large amounts of unbacked tokens and siphoned off at least $25 million, according to Chainalysis. Chainalysis said the attacker gained access to Resolv's AWS Key Management Service, where a privileged signing key was stored, enabling them to approve minting using the protocol's own permissions. Two transactions stood out: one mint of 50 million USR, followed by another 30 million, bringing the total to 80 million newly created tokens. Despite the size of the mints, Chainalysis reported that the transactions were triggered by comparatively small USDC deposits of about $100,000 to $200,000, which were used to generate inflated swap outputs. The attacker then moved quickly, converting USR into wrapped staked USR (wstUSR), a derivative representing a share of a staking pool rather than a fixed token amount. From there, the funds were swapped into other stablecoins and then into ETH, with the trail obscured through multiple decentralized exchange pools and bridges. Resolv Labs confirmed the incident, attributing the unauthorized minting to a compromised private key. The team paused contracts shortly after detection and said it was able to burn nearly 9 million USR held by the attacker. It also said roughly $0.5 million in redemptions were processed before operations were halted. Chainalysis estimates the attacker controls about 11,400 ETH, valued around $25 million at the time of the theft, and also holds about 20 million wstUSR, valued significantly lower. Market impact was immediate. CoinGecko data shows USR fell to an all-time low near $0.14 after the exploit. The token later rebounded modestly, but was still down more than 57% over the past 24 hours at the time of writing. Resolv said at least 71 million illicitly minted tokens remain in circulation. CoinGecko places USR's circulating supply at just over 176 million tokens. The team has started a redemption process for all USR minted before the incident, beginning with allowlisted users. The breach lands as stablecoin adoption continues to be framed around operational efficiency and security. A recent Ripple survey found 74% of finance executives view stablecoins as useful for cash-flow and treasury management, while 89% prioritize secure custody when choosing providers. Resolv said it is working with partners, law enforcement, and analytics firms to trace funds and pursue recovery, and it urged users not to trade the affected tokens while remediation is underway.

MicroStrategy, the largest publicly traded corporate holder of Bitcoin and led by Michael Saylor (now operating under the name Strategy), has expanded its BTC treasury with a fresh purchase worth about $76.6 million. In a Monday filing with the U.S. Securities and Exchange Commission, the company said it bought 1,031 BTC at an average price of $74,326 per coin, slightly below its overall average cost basis of 75,694. Following the disclosure, shares of MicroStrategy (MSTR) rose 2.57% to $139.14 on Monday. The latest addition brings the company's total Bitcoin holdings to 762,099 BTC. MicroStrategy also said it has spent an estimated $57.69 billion building its BTC treasury over time. The new buy marks a notable slowdown from the two larger acquisitions announced earlier in the month: a 22,337 BTC purchase valued at roughly $1.6 billion, preceded by a 17,994 BTC purchase worth about $1.3 billion. Funding also shifted versus the prior week. The 22,337 BTC deal was largely financed through issuance of perpetual preferred equity known as STRC, with the STRC sale raising nearly $1.2 billion, covering about 75% of that purchase. For Monday's acquisition, the company used its Class A common stock. In total, MicroStrategy has acquired 41,362 BTC in March, spending nearly $2.93 billion. Bitcoin's price decline has weighed on the value of its holdings: CoinGecko data indicates the treasury's value is down about 7%, estimated at roughly $54.4 billion at the time of reporting, with BTC trading at $71,446. Corporate interest in Bitcoin treasury strategies is also rising beyond the U.S. Stockholm-based, publicly listed H100 Group said it plans to increase its Bitcoin exposure through acquisitions and has signed a letter of intent to buy Norwegian companies Moonshot AS and Never Say Die AS. If completed, the transaction would allow H100 to own nearly 3,500 BTC, positioning it among Europe's largest Bitcoin treasury companies. H100 said the proposed transaction is share-based with no cash component, structured as a Bitcoin-to-Bitcoin exchange. Ownership in the combined entity would be determined by the BTC value contributed, a structure the company says is designed to avoid diluting existing shareholders. The companies involved currently hold around 2,450 BTC combined. H100 expects agreements to be finalized by April 22, with completion planned soon after its annual general meeting in May, subject to required approvals. H100 shares rose 2% on the day.

Shiba Inu (SHIB) has gone live on OnePay, a U.S. fintech app majority-owned by Walmart, opening the token to more than 3 million monthly active users. The integration enables OnePay customers to use SHIB for purchases in Walmart stores, online, and through the OnePay Later app. OnePay also supports crypto-to-fiat conversion, positioning SHIB beyond trading and toward everyday payments. OnePay said on March 20 it added 10 new cryptocurrencies, taking supported assets on the platform to 12. The new listings include XRP, Solana (SOL), Dogecoin (DOGE), Cardano (ADA), Bitcoin Cash (BCH), Chainlink (LINK), PAX Gold (PAXG), Polkadot (DOT), and Uniswap (UNI). Bitcoin (BTC) and Ethereum (ETH) have been available since launch. Users can buy, sell, and hold these assets directly in the app. Regulatory clarity also improved for SHIB this week after the U.S. Securities and Exchange Commission (SEC) issued updated guidance on crypto classification and confirmed Shiba Inu is treated as a nonsecurity. The update is part of broader U.S. efforts to separate established cryptocurrencies from unregistered securities, which could ease adoption across consumer fintech platforms. At the time of writing, SHIB traded at $0.00000577, down 3.63% over 24 hours and 1.52% for the week. Trading volume fell to $104.52 million, reflecting lighter weekend activity. Analysts said expanding mainstream payment access could support longer-term stability and growth in real-world use cases. OnePay is valued at $4B and offers banking, savings, credit cards, BNPL and investing, with crypto purchases available from $1.

ChainCatcher reports that, citing CNBC, CME's FedWatch tool indicates markets are pricing in a 7.2% chance of a 25-basis-point Fed rate hike in April, versus a 92.8% probability of no change.

Delaware lawmakers have filed Senate Bill 19, a proposal that would set clear guardrails for stablecoin issuers operating in the state. The bill calls for full 1:1 reserve backing, requires monthly audits, and mandates AML/KYC compliance. It would also bar issuers from offering yield to token holders, a move aimed at bringing Delaware's framework in line with the federal GENIUS Act.

Digital asset investment products attracted $230 million in net inflows in the week ended March 20, 2026, sharply down from $1.06 billion the prior week, CoinShares said in its weekly report. Total assets under management (AUM) across all digital asset investment products stood at $138.02 billion as of March 20. CoinShares attributed the slowdown to markets interpreting the US Federal Reserve's Wednesday meeting as a hawkish pause rather than to geopolitical developments. The first two trading days brought $635 million of inflows, before the FOMC meeting was followed by $405 million of outflows. Year-to-date flows across all products are now $1.405 billion. Bitcoin drove most of the week's inflows, pulling in $219.2 million and lifting its year-to-date total to $1.155 billion. Bitcoin-related AUM reached $109.49 billion. Short Bitcoin products also posted $6 million of inflows. By issuer, iShares led weekly inflows with $257 million, taking year-to-date inflows to $1.148 billion and AUM to $62.97 billion. ProFunds Group recorded $35 million of inflows, and 21Shares AG added $12 million. On the outflow side, Fidelity saw $105 million leave during the week, though its AUM remained $15.62 billion. ARK 21Shares posted $28 million of outflows, Grayscale $26 million, Bitwise $6 million and CoinShares $3 million. Solana extended its inflow streak to seven consecutive weeks, adding $17 million and bringing cumulative inflows to $136 million. SoSoValue data showed SOL spot ETFs had cumulative net inflows of $989.78 million as of the week ended March 20, with total net assets of $874.61 million. Weekly inflows reached $21.10 million, up from $10.70 million the previous week. The seven-week run follows a low point in the week ended February 6, when the category saw $8.92 million of outflows and cumulative inflows stood at $862.01 million. Elsewhere, Chainlink drew $4.6 million in weekly inflows, lifting year-to-date inflows to $40 million and AUM to $134 million. Hyperliquid recorded a $4.5 million inflow, Sui added $1.5 million, while XRP posted a $2.9 million outflow. The 'Other' category took in $8.6 million. Ethereum reversed course, reporting $27.5 million of weekly outflows and ending a three-week inflow streak. Ethereum products now show a $50 million net outflow year-to-date, with AUM at $16.83 billion. Month-to-date flows remained positive at $378.1 million. The prior three weeks saw inflows of $160.82 million, $23.56 million and $174.15 million. Regionally, every market tracked by CoinShares recorded net inflows for the week. The United States led with $153.6 million, bringing month-to-date inflows to $1.85 billion and year-to-date inflows to $638.8 million. US AUM totaled $114.95 billion, the largest by country. Germany posted $30.2 million of inflows after $17.1 million of outflows the previous week; year-to-date inflows in Germany stand at $377 million with AUM at $5.96 billion. Switzerland added $27.5 million, Canada $9.3 million, Australia $1.9 million, Brazil $2.4 million, Hong Kong $1.2 million, and the Netherlands and Sweden $1.1 million each.

Marc Syz, a member of the Syz banking family, is separating from Banque Syz to pursue a Bitcoin-centered strategy and take the family's 5,000 BTC holdings public. According to information cited by Bloomberg, the split revolves around Future Holdings AG, which holds 5,000 BTC valued at roughly $450 million. While Banque Syz is sticking with conventional wealth management, Syz is pushing ahead with partner Richard Byworth to list the Bitcoin treasury as a standalone vehicle, a model that echoes approaches popularized by firms such as MicroStrategy. Regulatory filings submitted to Switzerland's FINMA on March 15 show Future Holdings AG is seeking an IPO with a dual listing on Nasdaq and the SIX Swiss Exchange. The company aims to raise CHF 500 million, with proceeds intended to expand its Bitcoin treasury. The move underscores a widening rift in Swiss private banking over digital assets. PwC estimates that 28% of Swiss banks plan to allocate 5%–10% of their portfolios to crypto by 2027, though adoption has been slowed by internal disagreements at some institutions. Traditional players continue to cite volatility, regulatory uncertainty and client expectations as reasons for caution. Syz has framed the strategy around Bitcoin's role as a hedge against monetary debasement for family offices, arguing that a public listing can offer investors direct exposure to BTC while scaling the firm's holdings.
