Stablecoins have become the dominant rail for USD-denominated spot crypto trading, making up 83.03% of volume in late-March 2026. Fiat USD pairs accounted for 16.97% on centralized exchanges, a drop from 2021 when stablecoins held 77.75% and fiat pairs 22.25%. The shift reflects stablecoins' growing role in liquidity and settlement across both centralized markets and DeFi.

Dogecoin, Shiba Inu and Pepe Coin gave back part of earlier gains as meme-coin momentum cooled, with traders watching nearby support zones. Dogecoin was around $0.09324 (down 2.25% in 24 hours), while SHIB hovered near $0.00000613 (up 0.10%) and PEPE near $0.00000349 (down 0.59%).

EDXM International says it will roll out a blockchain-based Korean won perpetual futures contract in April 2026, designed to track KRW/USD via a synthetic KRWQ/USDC pair. The product settles in USDC and uses an offshore won-backed stablecoin structure positioned as an alternative to traditional KRW non-deliverable forwards, a market cited at roughly $27 billion in average daily volume.

Shiba Inu (SHIB) is trading near $0.00000610 and is holding above its 23-day and 50-day moving averages, while price structure shows higher lows forming through March. A double bullish divergence on the RSI and a breakout above $0.00000504 are being watched as signals of improving momentum. If resistance levels give way, the 200-day moving average near $0.00000842 is cited as a potential upside target.

Bitcoin and Ethereum traded in narrow ranges as markets weighed Middle East headlines, while meme coins drew more speculative flow. Shiba Inu gained 7.12% and Dogwifhat rose 10.35%, and Maxi Doge (MAXI) said its presale has raised more than $4.7 million. MAXI was priced at $0.000281, with the next presale price step scheduled for tonight.

Circle Internet Financial shares (CRCL) fell 22% on Tuesday to $98 after reports said a revised Senate Banking Committee draft of the CLARITY Act would restrict stablecoin-related rewards. The text would bar platforms from offering yield "directly or indirectly" for holding stablecoins or assets treated like bank deposits, potentially affecting business models tied to interest on reserves.

Tether says it has begun the process of commissioning a full audit by a Big Four accounting firm, expanding its disclosures beyond periodic reserve attestations. On March 23, 2026, Celo reported more than 5 million weekly stablecoin users and 7.2 million+ stablecoin transactions last week, pointing to rising USDT utility. The move comes as a draft of the US Clarity Act sparks fresh concerns about potential restrictions on stablecoin yields and related rewards models.

Tether has taken a strategic stake in AI sleep-tech firm Eight Sleep at a $1.5 billion post-money valuation, positioning the deal as more than a passive investment. The move draws on Tether's reported 2024 profit of over $13 billion and its $6.3 billion in excess reserves, which it has been deploying across multiple venture divisions.
